The gravity decreasing as you approach the core is realistic. The further down you get, the less matter will be below you, pulling you down, and more matter above you pulling you up.
Stephen Prendergast I must add that matter does control gravity but... another to add in is time. try and study that up. time can change a lot of things even warp space. maybe make a anti- matter engine.
+Tjb140 Not really; I tried bombarding a planet for 3 hours with about 25 orbital strike platforms all dropping a constant stream of explosives that ended up blowing a hole roughly 3 km in radius and 1 km deep, but when I view the strike site from orbit I couldn't see it.
They should put a "molten core" in the planet, that would make deleting objects much more reasonable. Basically just a spherical object with a lava texture.
Ian Fitzgerald It was a joke, sorta... Unless you go through the core, if you continue in a straight line as some point you are going to be moving perpendicular to the gravity field.
The lower gravity as you go down is actually very realistic. As you go down, you start having stuff above you exerting its own gravity to pull you back up. At the exact center of a perfectly spherical body, you would be in zero G as you are being pulled equally from all sides. This is also why a hypothetical "Tunnel to China" wouldn't need engines. Gravity starts pulling you down, acceleration slows the deeper you go and completely switches to deceleration once you pass the halfway point. Interestingly enough, such a tunnel would have the same travel time from New York to Los Angeles as it would New York to Sydney.
+OtakuMage Wouldn't need engines if your entire tunnel was vacuum, otherwise air friction would slow you down and you'll eventually end up at the center. Plus you have the whole pressure and temperature and the mildly annoying issue of the metal core at the center of our planet... :p
+Bart Wijshake Molten metallic core. Look up how it works, The lava is called magma in the earth with its gaseous component mixed in, The magma comes up from the mantle, a thin layer of semi-molten rock. We live on top of the earths crust. The crust is in sections called tectonic plates that rest on top of the mantle which flows via heat based pressure currents called convection currents, its all a mix of rocky minerals and metals, Eventually, you get deep enough to reach the outer core, A highly liquid like portion of the core which has heavy convection currents and has many elements including pretty much all metals from hydrogen to francium and even higher up the chain, its the flow of these convection currents in the outer core that give the earth its magnetic field, the north and south polar magnetic field. Then you have the inner core, which is made of the same substance as the outer core, but due to how much pressure is being forced onto it from the weight of the outer core, mantle, crust and even the air all around us, its squished into itself from all directions and acts more like a solid, due to mass compression. contrary to popular belief, the inner core is not what makes the earths magnetic field, but from what we can tell, it may spin. Also the outer layers of the inner core and inner layers of the outer core may sort of break away and reform into each other as they bridge the gap of liquid and solid. Thats geology for ya! :)
Hi there, it’s me Jack the time traveler, I come from 3 years later and we now have the ability to drill all the way through the planet in space engineers
That sucks. I want to be able to drill *through* the planet and pop out the other end. Man, they need to get rid of the fucking speed limit anyway. 104 m/s are annoyingly dull.
***** Thanks, guys, I'll check that out. But the thing is, I want them to get rid of the speed limit altogether. I get that it's hard to do with the physics engine and all that but I really think it would add a big big bunch of goodness to the game if it were to work.
***** That's really unfortunate. It's one of my biggest complaints about this game. I want to build giant ships and accelerate to ludicrous speeds and get in trouble because I didn't think of also decelerating. I want to build fancy mechanisms for quick deceleration, using gravity or maybe something like an aircraft carrier's cable. Basically I want to be able to play with speed in mind in this game and that's just not possible with a speed limit. It's like a hard limit on my inventor's spirit. :D
+HOLyPumpgun | Gaming again, theres mods that remove the speed limit. and "i get that it's hard to do with the physics engine and all" umm yeah... case and point.
gravity has nothing to do with pressure. As you get deeper and deeper into a hole, there is more and more of the planet above you pulling you up, and less and lees of i underneath you, pulling you down. right at the centre, both are exactly equal, an you are net zero gravity.
everything with mass has a gravitational effect. every little atom. The way gravity works, the math works just as well and is much easier to do calculations with, if we just assume the mass of the whole planet sits at the centre of mass at it, when thinking about it's effects on anything above the surface. Now, as soon as you are underneath the surface, there is mass above you. rocks, dirt, grampas 57 chevy convertible....it all has mass, and it effectively pulls you up a wee bit. So slightly younteracting the grav. pull of the rest of earth. If you're at the centre, half the planet pulls you up, half pulls you down...net effect = zero gravity For a diffrent approach, Look up shell theorem, to see, how at any given depth into a planet, you can basically exclude everything further from the centre of the planet as you, the wholce damn shell, as the geometry and the way gravity decreases with the square of the distance means the ent pull of the whole shell 'above' you is zero. The further you go towards the centre, the less stuff there acually is exerting a net grav pull on you. at the centre itself, it's zero.
+Almighty Eragon That's unecessary work, it's even more expensive to make it go through the center of Earth than just have it simply fly off, I can work the math for you if you want...
it would't work as well as you're thinking. like frank said there's gravity on both sides of the planet... lets just say there was a perfect tunnel going straight through the center of the earth. you jump down... assuming no air is in the tunnel your acceleration would start becoming slower and slower till you reach the core, then you would start accelerating in the opposite direction (or decelerating). then once you reach the other side of the tunnel, your velocity would become 0 and you would just start the process all over again.
Anonymous Gaming Why you should get thrown back up? You enter your tunnel at a velocity v, accelerate until you've reached the masses centre then start deaccelerating until you reach the opposite surface (given you travelled through a perfect sphere and your mass didn't change) with a velocity v' that is exactly equal to v.
If I went to a planet I would probably dig a hole like that one for my base. I have always liked the idea of an underground tunnel network or city with one (or a few) central tunnels straight down like that, while the main bulk of the network is a series of branches at various depths.
Darin Anderson The last free Human city in the Matrix films...referenced in the first matrix, showed to us in The Matrix Reloaded, and attacked in The Matrix Revolutions. It was a massive underground city that had been destroyed and rebuilt quite a few times, only, (spoiler) no one ever knew it HAD been destroyed and rebuilt
Lazurkri Also the 'real world' turns out to be another level of the matrix, designed to contain the 1% of people who rejected the matrix, to trick them into thinking they are really free. That's why there is no trace of Zion being destroyed before because they just reboot and start again.
Hey Arron, i wanted to give you an idea for a hangar. Basically its a small ship with welders attached but at the same time connected to the station using advanced rotors and conveyors to link it directly into the stations storage. To do this you will need 2 rotors to allow it to point in any direction like in custom turret designs, and on that a zigzag kind of thing with rotors to allow it to move forwards and backwards. This would be soooooo useful so you don't run back and forth refilling your welding ship with stuff. Pls like this so he sees it.
they could use the center of the planet to add some of the more completely fantastical science fiction stuff in. Like every one in 100 planets has a hollow center with with some rare element to mine like a metal that allows your ship to defy gravity without being powered or a crystal that can be used as an infinite power source.
+nevercallmebyname nah, SE is all about being realistic (without being too much of a sim). You can't defy gravity...ever. Some ore that is a very sustainable power source could work, but it should require you to have some form op top tier gear, or else it would be way too easy.
+CrazyDutchguy In a hollow planet situation or at the core of a planet the net acceleration due to gravity will be zero. The gravity is still there, but you'll be floating about the middle.
Hahaha! Well done Aaron, I wondered when someone would try this. I'm impressed Keen allows us to drill that deep into planets. I guess 4.5-5 miles deep is far enough for an underground base to be safe from orbital bombardments.
Just wanna let you guys and +LastStandGamers know, this video is no longer accurate; not sure of when it was changed but as of october 8, 2016, i know for sure that it has changed, because i'm writing this comment on a tablet while my computer is busy proving it... :P i'm 16.92 km deep, at time of writing, and gravity is at .72g; there's been no signs of problems, thus far, and those numbers are increasing enough that i've needed to update them three times while typing this. For those wondering what i'm doing, i've got a macro pressing w for .1 seconds, every .5 seconds, while my usual .1 second rapid fire left click macro creates obscene amounts of small block warheads directly in front of me, to fall, explode, and do my digging for me. It's in what was about to be my vanilla testing world; stable branch, and the only mod in it is a speed limit remover, unlimited one by (Midspace? Mexpex? can't remember, but it's one those.) any chance you could investigate/update this further, Aaron?
Maybe in the future the Space Engineers developers will add heat so you can't digg depper because your ship and yourself will melt. Maybe diffrent materials can handle heat better and be able to digg depper and depper too. The depper you go and better ore quality you get.
+Simon Engelholm heat would be very cool. also if a ship could melt from the reentry in the atmosphere or the player freezes to death in space if the ship interior has no heater. They could have the vents that allready are in the game collect N2 on the earthlike planet to use it as a coolant.
If you happen to clip your character through the terrain and fall to the centre of the earth (had this occur when a friend landed a ship on my head) the game becomes extremely glitchy. Gravity hits 0 as expected, but the closer the character gets to the actual centre of the planet, the glitchier the graphics become. It's the same type of graphics glitches that occur in some engines when the camera is outside of the skybox.
ive been a long time subscriber of ur channel, your videos have always attracted me more and more to space engineers, i already own the game on steam, and i like it and everything, but everytime i see ur creations, it gives me the hype to build complex stuff in the game, once i go in the game, start with my invention, get brain tumors and then exit the game,... ur commentary and play shows how basic me and a couple of my friends are in the game ;P
2:40 You're joking right? this is primary school stuff. The closer you get to a planet's core the lower the effects of gravity are. Sitting at the center of a planet (assuming there was a temperate hollow there for you to do so) you'd be under "zero gravity" as the gravity of the planet is acting equally on you from all sides.
24 25 Are you kidding me? Gravity is a fundamental to any physics class. If you went to school and never even learned about gravity I'd have to say the quality of your whole education comes into question.
Hey Arron, I'm surprised you haven't weaponized the monolith yet! Thing looks really dense...could probably do some serious penetration to heavy armor at a high relative velocity ;) I bet it would take a lot of G-force to accelerate it though assuming that it is even affected by gravity. Maybe one could use landing gears and a ship with a really long line of sight and hydrogen thrust to get it up to speed? Anyway thanks for the awesome vids, I always get super excited when I see new uploads from you! Have good one.
I actually do know what happens at the center of the planets, as a friend of mine once fell through the surface of the earth when we were trying to reach it with huge amounts of explosives. I convinced him not to exit his game, and we found that you can fall through the weird void that exists until something is mined until gravity drops to around 0.1 G, at which point you freeze up and the game spasms out. We have not been able to replicate this yet, but it is interesting.
+Pan kurczak Actually that IS how gravity works. As more of a planet's mass is above you, the less there is pulling you down. This isn't true for Earth only because Earth's density is not constant--but that has nothing to do with the physics of gravity. If it were the opposite, and most of the mass of Earth was at the crust, if you went down far enough you would be pulled back up.
+Pan kurczak I can not agree with You. We consider gravity to work like that to ease our calculations but any given (well You have to make exception for some theoretical particles but protons, electrons even photons are o.k.) particle has its own gravity which means that center of mass is just a point where all those forces are in balance. If You place yourself (in shape of perfect ball of matter :-D ) in center of mass of huge perfect hollow sphere made of lead, walls would try pull You to them but all those forces would negate each other. You might imagine it as static version of a Lagrangian point. :-)
The gravity decrease is actually following real-physics. From infinity to the surface, acceleration due to gravity follows the inverse square law (proportional to 1/r^2) so gravity increases as r (which can be seen as distance) decreases. However, below the surface the gravity starts to follow a linear pattern that decreases the closer to the core you get. If I remember correctly, that is because the closer to the core you get, the more material there is around you that is exerting a gravitational force in all directions. Not to sure on that last bit, the explanation, but I know gravitational force (and thus acceleration since f=ma) decreases after you go below the surface.
I've watched a few of your videos on space engineers for a while now, and it makes me wanna play it again haha. I got bored of it and haven't played it in almost a year because I got kind of bored trying to upkeep my asteroid base with constant mining, and I was singleplayer which got boring and lonely. Though I shall try it now that it has planets =D
At the moment, you're better off using voxel hand to dig a hole through the planet. Its a pretty cool effect if you have a high speed mod on. Once you get the the center of the earth like planet, the screen goes white, black tears start to grow and eventually the screen goes black, and everything becomes lighter as you approach the surface of the other side of the planet.
Hey Aron, the reason for the decreasing gravity is that the part of the planet that is above you pulls you in its direction. So if u are in the middle u have equal amount of mass around u that pulls you in its direction so u wont feel gravity in the middle of a planet
Vinn_mobile Stupit? Earth is flat. Chemtrails! Ok just kidding. Gravity pulls you to the center of the mass. If you are in the center of a planet, incredible gravity from every direction would affect you. You will be simply compressed.
+Skythedragon So you are trying to add to a conversation without having listened to the conversation? Person A: Man, did you see the game last sunday? Person B: Yeah! Did you know it was the player's birthday? Person C: I like ketchup!
Actually it does make sense that the gravity would begin to drop the deeper down you go. I believe vsauce had a video explaining travel through the center of the world, it's all mass based and once you go down so far you'll actually begin to slow up as you approach the core. This is because the further down you go the more mass is going to be above you, so once you get to the core (ignoring the pressures and heat) you'll probably just float there. Good job on the dev's part for thinking about that and doing their research.
Hey, I don't know if you know this yet, but you can get to the center of the earth with voxel hands, and dig a tunnel just as wide. If you hold the button, you can usually fly straight ahead through the center at max speed. After the hole is cut, any thing can go straight through. It is 0 gravity at the center, and you can make really cool little orbits in the core with stones and things.
Alright i did it... well not really, but got far enough. you can go down with a ship till around 6.5k - 7k after that, items will disappear. you can still use your hand drill, but once you reach a point which is not to far from the "disappearing" point, your drill will start to auto-unequip. after that point you can spam the slot and have it work little by little, but then you get to a point at which you can't mine any more (my characters flashlight broke at this point too). This far down all you can do is use the creative mode voxel tools (spectator mode is recommended). and that my friends is how you drill through the planet, with voxel hands and a lot of time. PS: i believe that at the core of the planet gravity is 0.05g-0.00g.
figuring out the actual gravity acting on a drill going to the core of a planet is quite complex. There are three main considerations: a) the gravitational force due to the cores mass will increase, since you lessen the distance to the baricenter b) the deeper you got, the higher the amount of mass, which only contributes a small percentage towards downward force or even counteracts it, since it is "above" and "beside" you c) a planets mass isnt distributed evenly throughout its volume. So realistically speaking gravity would increase for a while, then drop until hitting perfect equilibrium once you reach the center of mass. All the way through youd experience fluctuations.
Haven't seen it mentioned yet, so here it goes: Lower gravity deep beneath the earth actually makes sense, because a lot of the planets mass will be above you, when you are deep underground. As gravity comes from mass, this means that the earth above you starts to get so massive, it pulls back at you, so you would actually feel less gravity deep below.
For anyone that's still curious: the gravity goes to 0.01g around the planets core (I assume 0 if you stand perfectly in the core) so you do just float around. Other than that there's nothing exciting down there. The lighting does go a bit strange because its day on one side and night on the other. And if you place a space station cube it seems to get a strange light in the corner that's right in the middle of the planet but I dont know what that is.
The gravity going down is actually realistic, when you get closer to the core the gravitational pull from the other side of the planet gets higher and in the middle it balances out. thus making you weightless. (Sorry for my bad English)
The gravity decreasing with great depth is wholly consistent with real life physics. At the center, there is a lot of pressure, but you are surrounded by mass in all directions, so you won’t accelerate in any direction. At the surface, there is only mass below, so gravity is higher.
the gravity going down makes perfect sense ,gravity doesn't pull you too the center but to mass ,once you go down far enough the gravity of the mass above starts pulling you up so if you got to the center you would feel the gravity from every point around you ,making zero gravity
Anyone else interested in watching Aaron and his gang turning a planet or moon into a Coruscant-style planetary base? This could turn into another awesome series to watch them drill through a planet, making a secret empire underground that would lure traveler in and ..... MUAHAHAHA
The gravity decreases inside the planet because part of the mass is above you, cancelling the field partially. At the center, there is no gravity because there is equal mass on all sides and so the net effect is zero. Im actually happy the game takes this into account rather than treating the gravity as having a point source.
I've got to the center of earthlike planet, it took me 7 attempts to design a mole that works by gravity and not being damaged by bumps, no mods used. It's got to the center over 9 hours of drilling and got stuck in the center, because of zero gravity. It's actually was wobbling for about 10 meters up and down like a yo-yo.
There are several reasons you would want to dig to/ through the core. Several of those reasons involve Bases. Some are Hangers and Ship Yards. And Lets not forget about SECRET BASES. And some good old fashioned Mining.
They have been added this "disappear" thing. In first time i have played with planets, i did drop warheads down to my hole, and i've been reaced the "center". It was the empty sphere with strange gravity in it - thats all i can remember
Hmm... The gravity dropping is what would actually happen as you get closer to the core of a planet, because of the fact that there is enough mass behind you to counter the gravity of the mass in front of you. I commend the devs for actually getting that to work.
@LastStandGamers it has to do with atmospheric pressure. as you dig further down, the pressure of the atmosphere is weighing down on you less. So it's not necessarily that the gravity has gotten lower. It's getting higher. but now the earth is holding up the atmosphere, instead of your shoulders, as an example.
The furthest down we drilled so far to my knowledge is 12066m (kola peninsula on russian soil), reaching 180°C on the bottom. Studies revealed through meassuring weight that gravity below ground is actualy lower as the mass above increases.
7km down... you could build one hell of an underground base with that!!! And being so deep, orbital bombardment would take forever to blast through into the base :D
Just out of curiosity, have you considered going around to the opposite side of the planet, and doing the same thing to see if you can somehow make your tunnels meet up in the middle? What about going around the core? IE: Dig sideways and down until you've marked out the boundary of where you can no longer dig?
I have gone much deeper. I think maybe it didn't work for you b/c you were creating the bombs with the admin tools. Maybe you should have tried spawning your drilling ship at the bottom of the hole it would have kept going deeper. I'll have to put up a video of my setup. Very nice drill you have there btw. :)
Step 2: mine off the entire 7km deep layer of a planet's surface. Then see if what's left can be affected. If not then build your base just slightly above the surface and let them attack you with warheads and such, and dodge. You'd have no problems with explosions if they are absorbed. It would be interesting, keeping this in mind, to test depths possible on constructed items, compared to objects moving into the anihilosphere from further out. Would you be able to construct something in that area, what would happen to projectiles from guns, rather than constructed 'warheads'? A lot can be done to see what is possible with this zone you've found.
It's probably to delete rogue ship parts that clip through the terrain upon impact at high speeds. I've noticed this happens as new grids are formed by a destroyed ship, and the "new" grids sometimes pop through the terrain. Since the gravity will pull everything to it, it makes sense to make a "kill zone" should the garbage collection system miss some grids that have clipped through the terrain.
To answer your question, yes gravity decreases as your depth increases (on Earth anyways). Eventually your gravity would be 0 at the core, due to a net gravitational force of 0, as all forces begin to point outwards (from varying masses on the surface/away from the core) and thus, zero gravity
I have been to the center of a planet... Its actually really easy. Set up a macro on your mouse or keyboard that perpetually holds down the right mouse button. Then, in creative equip voxel hands. Hover over the ground looking straight down, press the RMB macro to delete the ground in front of you. Then you just turn off your inertial dampeners and walk away and let gravity do the work. It takes like 5 minuets or something like that to get to the bottom but it's pretty cool because there is a tiny anti gravity zone in the middle of the planet!
Building a underground base at that depth would certainly keep you safe. Only you would have required to build a lift system to get people down. and it would probably require a stair case that reached the surface and was hidden in a cave in case of emergencies.
Had a friend fall from orbit as an astronaut and we had faster speed mod. He hit the surface so fast he phased through the ground and his character flew toward the core of the planet. Then he literally began to orbit the planet from within. He was flying a few kilometers under the surface, perfectly orbiting the core of the planet at max velocity. Turning his jetpack with dampeners on had absolutely no effect because he was going at least 5 km/s. I was on Mars and could see his player transmission quickly bounce back and forth from side to side as he flew around. That was an interesting rescue attempt. Had to give him admin so he could teleport out. ;
Physics lesson: All gravitational forces balance/cancel each other out at the center so you end up with 0 gravity at the gravitational center of a planet, assuming you can get there. The gravitational center of a planet may be different then the geographical center because a gravitational force in one direction may be stronger than a g-force in another direction.
you can place some gravity generators along the tunnel sides to mantain the ship centered. Or wheels + suspension. Even a system that can balance the ship perfectly vertically (with gravity generators) would be enough to avoid collisions
idk how many of the comments you guys read, but i have a cool idea. What would happen if you used some sort of level editor to delete the whole planet except the middle part that deletes everything it touches? Would the gravitational field still be present? If so would that basically make the planet a space engineers black hole?
A purpose I might see is having an enormous hangar near a planet's core, either for shielding it with the ground, invading someone's base from below, or just for the cool factor. Imagine jumping inside a planet!
Better way to make it to the center: Go on a server with high ping and some speed mods, spawn in suit, and use your jetpack to increase downward acceleration. Once you've clipped through the planet, just remove your helmet and let gravity do the work.
Aaron, now with this info, what if you dig, straight down, on the side of a planet, like, 7km north of the equator and dig down 'till you pop out 7km south of the equator? would that allow for a 14 km tunnel to ship goods through? How far from the equator could you go to still have that work? (assuming it works at all)
It's cool that they made that when you dig into the planet, the gravity decrease. That's realistic in the way that you're attracted by the center of the planet, but also by the rock/dirt above you. So as you get closer to the center, the gravity decrease cause of the matter attracting you from all angles, to the point where the gravity reach the 0 level cause your at the center of the planet.
Continue drilling with your hand drill.
See you in 5 years.
+Burak Baggins it gets deleted

OH MY GOD HE DOESN'T AGREE WITH YOU. CAPS LOCK ENGAGE
The gravity decreasing as you approach the core is realistic. The further down you get, the less matter will be below you, pulling you down, and more matter above you pulling you up.
But the pressure can eventually crush you
Christopher Lefont
Pressure? Maybe in the future.
András Fogarasi well on earth you would die from the radiation from fusion and pressure but on a hollow earth yeah no gravity in the middle
Stephen Prendergast
I must add that matter does control gravity but... another to add in is time.
try and study that up. time can change a lot of things even warp space.
maybe make a anti- matter engine.
Stephen Prendergast fusion? What are you talking about?
this is a solid waste disposal method. A real way to get rid of that 2000k kg stockpile of stone.

They allow you to drill through planets now.
next objective: cut a planet in half
+CasualLetsPlay Also impossible, considering you can't even reach the core much less tunnel through the planet
+CasualLetsPlay Cut the planet in third? lol
+Demonicpain10 You can with voxel hands, i just left a comment explaining my experience that i had just now
+Jack Outside the Box I wonder if you removed a large portion of the planet, would it be noticable from orbit?
+Tjb140 Not really; I tried bombarding a planet for 3 hours with about 25 orbital strike platforms all dropping a constant stream of explosives that ended up blowing a hole roughly 3 km in radius and 1 km deep, but when I view the strike site from orbit I couldn't see it.
They should put a "molten core" in the planet, that would make deleting objects much more reasonable. Basically just a spherical object with a lava texture.
TuttyGaming I want fluids like Magma and Lava planets, or gas planets and oceans on the earth.
what are they hiding at 8km depth. a secret keen meme base?
That's actually where they translated Zero Wing.
That's where they hide the Atari E.T. Games....
It's obviously where they hide the clang
Huub900 or maybe they are hiding the birth catalyst of the old gods?
Maybe that's the one and only place where you can see John Cena?
How about drilling diagonally to try to "dodge" the core?
7k down, 60k total to the center. You really aren't getting very deep. You wouldn't be diagonal, you would eventually be horizontal.
+Ryan Gunn any core dodging would by definition become horizontal.
+Adam Boyd Lol, you make a good point :P
+Adam Boyd no I think it would act more like a week spherical generator at the core just need to thing round
Ian Fitzgerald It was a joke, sorta...
Unless you go through the core, if you continue in a straight line as some point you are going to be moving perpendicular to the gravity field.
The lower gravity as you go down is actually very realistic. As you go down, you start having stuff above you exerting its own gravity to pull you back up. At the exact center of a perfectly spherical body, you would be in zero G as you are being pulled equally from all sides.
This is also why a hypothetical "Tunnel to China" wouldn't need engines. Gravity starts pulling you down, acceleration slows the deeper you go and completely switches to deceleration once you pass the halfway point. Interestingly enough, such a tunnel would have the same travel time from New York to Los Angeles as it would New York to Sydney.
+OtakuMage Wouldn't need engines if your entire tunnel was vacuum, otherwise air friction would slow you down and you'll eventually end up at the center.
Plus you have the whole pressure and temperature and the mildly annoying issue of the metal core at the center of our planet... :p
+refreshfr That pesky, annoying metal core. Destroying dreams and ambitions since 4,540,000,000 BC.
refreshfr I said hypothetical, it has many issue of which air pressure is not the least. Casual use ICBMs are a more likely alternative these days.
+refreshfr metal? i thought we had lava in the center... :/
+Bart Wijshake Molten metallic core. Look up how it works, The lava is called magma in the earth with its gaseous component mixed in, The magma comes up from the mantle, a thin layer of semi-molten rock. We live on top of the earths crust. The crust is in sections called tectonic plates that rest on top of the mantle which flows via heat based pressure currents called convection currents, its all a mix of rocky minerals and metals, Eventually, you get deep enough to reach the outer core, A highly liquid like portion of the core which has heavy convection currents and has many elements including pretty much all metals from hydrogen to francium and even higher up the chain, its the flow of these convection currents in the outer core that give the earth its magnetic field, the north and south polar magnetic field. Then you have the inner core, which is made of the same substance as the outer core, but due to how much pressure is being forced onto it from the weight of the outer core, mantle, crust and even the air all around us, its squished into itself from all directions and acts more like a solid, due to mass compression. contrary to popular belief, the inner core is not what makes the earths magnetic field, but from what we can tell, it may spin. Also the outer layers of the inner core and inner layers of the outer core may sort of break away and reform into each other as they bridge the gap of liquid and solid.
Thats geology for ya! :)
Hi there, it’s me Jack the time traveler, I come from 3 years later and we now have the ability to drill all the way through the planet in space engineers
We do?
Ima wait to see how many likes this comment has in 3 years before i respond
That sucks. I want to be able to drill *through* the planet and pop out the other end. Man, they need to get rid of the fucking speed limit anyway. 104 m/s are annoyingly dull.
just download a mod, there's one that increases it to like 500m/s
***** Thanks, guys, I'll check that out. But the thing is, I want them to get rid of the speed limit altogether. I get that it's hard to do with the physics engine and all that but I really think it would add a big big bunch of goodness to the game if it were to work.
theres speed limit remover mods, buts a bitch to stop
***** That's really unfortunate. It's one of my biggest complaints about this game. I want to build giant ships and accelerate to ludicrous speeds and get in trouble because I didn't think of also decelerating. I want to build fancy mechanisms for quick deceleration, using gravity or maybe something like an aircraft carrier's cable. Basically I want to be able to play with speed in mind in this game and that's just not possible with a speed limit. It's like a hard limit on my inventor's spirit. :D
+HOLyPumpgun | Gaming again, theres mods that remove the speed limit. and "i get that it's hard to do with the physics engine and all" umm yeah... case and point.
In reality deep inside planet gravity is lower, because mass of planet is surrounding object. In theory in planet core gravity should be almost 0g.
What? The gravity should grow.
You would be compress in the middle of a planet (is speed=0m/s)
At the core, effectively zero
gravity has nothing to do with pressure. As you get deeper and deeper into a hole, there is more and more of the planet above you pulling you up, and less and lees of i underneath you, pulling you down. right at the centre, both are exactly equal, an you are net zero gravity.
LutzDerLurch What? No!
Gravity is going to the center of the mass!
everything with mass has a gravitational effect. every little atom.
The way gravity works, the math works just as well and is much easier to do calculations with, if we just assume the mass of the whole planet sits at the centre of mass at it, when thinking about it's effects on anything above the surface.
Now, as soon as you are underneath the surface, there is mass above you. rocks, dirt, grampas 57 chevy convertible....it all has mass, and it effectively pulls you up a wee bit. So slightly younteracting the grav. pull of the rest of earth.
If you're at the centre, half the planet pulls you up, half pulls you down...net effect = zero gravity
For a diffrent approach, Look up shell theorem, to see, how at any given depth into a planet, you can basically exclude everything further from the centre of the planet as you, the wholce damn shell, as the geometry and the way gravity decreases with the square of the distance means the ent pull of the whole shell 'above' you is zero.
The further you go towards the centre, the less stuff there acually is exerting a net grav pull on you. at the centre itself, it's zero.
If there weren't a speed cap you could use this kind of tunnel as a slingshot for ships getting out of orbit
+Almighty Eragon The speed effect would be zero, since gravity works the other way when you go past the core.
There are mods increasing the speed limit
you would have to use thrusts to speed up as you go down, its just to make gravity and the distance help you reach escape velocity
+Almighty Eragon That's unecessary work, it's even more expensive to make it go through the center of Earth than just have it simply fly off, I can work the math for you if you want...
it would't work as well as you're thinking. like frank said there's gravity on both sides of the planet... lets just say there was a perfect tunnel going straight through the center of the earth. you jump down... assuming no air is in the tunnel your acceleration would start becoming slower and slower till you reach the core, then you would start accelerating in the opposite direction (or decelerating). then once you reach the other side of the tunnel, your velocity would become 0 and you would just start the process all over again.
I was expecting some giant alien spider spawning as you reached the center...
This is quite GROUNDBREAKING
jhfridhem NOOOOOOO OH GOD. NO
This joke was ROCK SOLID

The winner doesn't exist.
The fact that the gravity is lowering is quite realistic.
+Anonymous Gaming Why?
Science man. Look it up
Anonymous Gaming
F = G * (m1*m2) / s^2
with your distance (s) decreasing and all the masses the same the gravitational force gets stronger
Then explain how you get thrown back up after you are about at the middle of the way to the center...
Anonymous Gaming Why you should get thrown back up? You enter your tunnel at a velocity v, accelerate until you've reached the masses centre then start deaccelerating until you reach the opposite surface (given you travelled through a perfect sphere and your mass didn't change) with a velocity v' that is exactly equal to v.
This is a certafied Dwarf Classic!
Rock and Stone Brother✊🤟
You could use the hand drill or the voxel hands at the bottom of the hole
+Nicholas Mills yes you can and i did it with the voxel hands
+Nicholas Mills Hand drill disappears as well lol
rly?
+Nicholas Mills yes it does. I thoroughly tested this out in a bug report feature after they announced planets and said you could drill through.
trekie4747
If I went to a planet I would probably dig a hole like that one for my base. I have always liked the idea of an underground tunnel network or city with one (or a few) central tunnels straight down like that, while the main bulk of the network is a series of branches at various depths.
+Darin Anderson So Zion then
+Chris Harvey or NORAD.
Chris Harvey It rings a bell... what is Zion?
Darin Anderson
The last free Human city in the Matrix films...referenced in the first matrix, showed to us in The Matrix Reloaded, and attacked in The Matrix Revolutions. It was a massive underground city that had been destroyed and rebuilt quite a few times, only, (spoiler) no one ever knew it HAD been destroyed and rebuilt
Lazurkri Also the 'real world' turns out to be another level of the matrix, designed to contain the 1% of people who rejected the matrix, to trick them into thinking they are really free. That's why there is no trace of Zion being destroyed before because they just reboot and start again.
Hey Arron, i wanted to give you an idea for a hangar. Basically its a small ship with welders attached but at the same time connected to the station using advanced rotors and conveyors to link it directly into the stations storage. To do this you will need 2 rotors to allow it to point in any direction like in custom turret designs, and on that a zigzag kind of thing with rotors to allow it to move forwards and backwards. This would be soooooo useful so you don't run back and forth refilling your welding ship with stuff. Pls like this so he sees it.
A true scientific experiement. "Hey, what happens if we do this?" "Idk, fuck it, let's do it!" Great video mate.
they could use the center of the planet to add some of the more completely fantastical science fiction stuff in. Like every one in 100 planets has a hollow center with with some rare element to mine like a metal that allows your ship to defy gravity without being powered or a crystal that can be used as an infinite power source.
+nevercallmebyname nah, SE is all about being realistic (without being too much of a sim). You can't defy gravity...ever. Some ore that is a very sustainable power source could work, but it should require you to have some form op top tier gear, or else it would be way too easy.
+CrazyDutchguy In a hollow planet situation or at the core of a planet the net acceleration due to gravity will be zero. The gravity is still there, but you'll be floating about the middle.
***** a hollow planet would collapse in on itself due to gravity and again form a sphere over time. Hollow planets are not possible.
CrazyDutchguy It's a hypothetical situation. It can't exist but we can still model what would happen if it did.
I'm sorry for having a computer.
Is it really so bad to want a little science fiction in my space gaming experience?
Hahaha! Well done Aaron, I wondered when someone would try this. I'm impressed Keen allows us to drill that deep into planets. I guess 4.5-5 miles deep is far enough for an underground base to be safe from orbital bombardments.
Just wanna let you guys and +LastStandGamers know, this video is no longer accurate; not sure of when it was changed but as of october 8, 2016, i know for sure that it has changed, because i'm writing this comment on a tablet while my computer is busy proving it... :P i'm 16.92 km deep, at time of writing, and gravity is at .72g; there's been no signs of problems, thus far, and those numbers are increasing enough that i've needed to update them three times while typing this. For those wondering what i'm doing, i've got a macro pressing w for .1 seconds, every .5 seconds, while my usual .1 second rapid fire left click macro creates obscene amounts of small block warheads directly in front of me, to fall, explode, and do my digging for me. It's in what was about to be my vanilla testing world; stable branch, and the only mod in it is a speed limit remover, unlimited one by (Midspace? Mexpex? can't remember, but it's one those.) any chance you could investigate/update this further, Aaron?
CONGRATULATIONS!!!! on your 700th video
Maybe in the future the Space Engineers developers will add heat so you can't digg depper because your ship and yourself will melt. Maybe diffrent materials can handle heat better and be able to digg depper and depper too. The depper you go and better ore quality you get.
Deeper
+Simon Engelholm heat would be very cool. also if a ship could melt from the reentry in the atmosphere or the player freezes to death in space if the ship interior has no heater. They could have the vents that allready are in the game collect N2 on the earthlike planet to use it as a coolant.

Back at it again Dr. Evil I see.
If they ever add active volcanoes w/ lava, then you will have a use for this.
O.O You've build many crazy contraptions in the past .... but this? Is by FAR the most ambitious ;D
Ambitious, not victorious ;D
If you happen to clip your character through the terrain and fall to the centre of the earth (had this occur when a friend landed a ship on my head) the game becomes extremely glitchy. Gravity hits 0 as expected, but the closer the character gets to the actual centre of the planet, the glitchier the graphics become. It's the same type of graphics glitches that occur in some engines when the camera is outside of the skybox.
ive been a long time subscriber of ur channel, your videos have always attracted me more and more to space engineers, i already own the game on steam, and i like it and everything, but everytime i see ur creations, it gives me the hype to build complex stuff in the game, once i go in the game, start with my invention, get brain tumors and then exit the game,... ur commentary and play shows how basic me and a couple of my friends are in the game ;P
Aaron, you have stopped nothing. Drill through the opposite side of the planet and meet in the middle.
themikead99 the planet is 220 kilometers wide. He only made it 7000 kilometers. He still would not meet in the middle.
7000 meters not kilometers
Congrats... you've made a giant colon that poops everything out into oblivion.
2:40 You're joking right? this is primary school stuff. The closer you get to a planet's core the lower the effects of gravity are. Sitting at the center of a planet (assuming there was a temperate hollow there for you to do so) you'd be under "zero gravity" as the gravity of the planet is acting equally on you from all sides.
We didn't learn that in _high school_, let alone primary.
Gazelle Samyueru
Well then your education was woefully remiss.
i never saw a school in my life which teaches anything about gravity :/
24 25
Are you kidding me? Gravity is a fundamental to any physics class.
If you went to school and never even learned about gravity I'd have to say the quality of your whole education comes into question.
Vriska Serket Well no shit our education system is non functional.
Hey Arron, I'm surprised you haven't weaponized the monolith yet! Thing looks really dense...could probably do some serious penetration to heavy armor at a high relative velocity ;) I bet it would take a lot of G-force to accelerate it though assuming that it is even affected by gravity. Maybe one could use landing gears and a ship with a really long line of sight and hydrogen thrust to get it up to speed?
Anyway thanks for the awesome vids, I always get super excited when I see new uploads from you! Have good one.
I have a good idea, why don't you make a space elivotor?
Elevator*
+Hayden Murphy did you see the latest patch video on the space engineers channel? someone did it and its awesome
+Fefeland Do it anyway.....
I actually do know what happens at the center of the planets, as a friend of mine once fell through the surface of the earth when we were trying to reach it with huge amounts of explosives. I convinced him not to exit his game, and we found that you can fall through the weird void that exists until something is mined until gravity drops to around 0.1 G, at which point you freeze up and the game spasms out. We have not been able to replicate this yet, but it is interesting.
Of course gravity decreases the further you go sown
+Pan kurczak that's irrelevant, if you went to the centre of the earth, gravitational force will equal 0
+Pan kurczak Actually that IS how gravity works. As more of a planet's mass is above you, the less there is pulling you down. This isn't true for Earth only because Earth's density is not constant--but that has nothing to do with the physics of gravity. If it were the opposite, and most of the mass of Earth was at the crust, if you went down far enough you would be pulled back up.
+Manofiron norifonoM Thats exact
+Pan kurczak
I can not agree with You. We consider gravity to work like that to ease our calculations but any given (well You have to make exception for some theoretical particles but protons, electrons even photons are o.k.) particle has its own gravity which means that center of mass is just a point where all those forces are in balance. If You place yourself (in shape of perfect ball of matter :-D ) in center of mass of huge perfect hollow sphere made of lead, walls would try pull You to them but all those forces would negate each other. You might imagine it as static version of a Lagrangian point. :-)
+Pan kurczak Took long enough to find, but I'm glad the comment chain didn't devolve into this: gifsoup.com/view/2382683/angry-mob.html
The gravity decrease is actually following real-physics. From infinity to the surface, acceleration due to gravity follows the inverse square law (proportional to 1/r^2) so gravity increases as r (which can be seen as distance) decreases. However, below the surface the gravity starts to follow a linear pattern that decreases the closer to the core you get.
If I remember correctly, that is because the closer to the core you get, the more material there is around you that is exerting a gravitational force in all directions. Not to sure on that last bit, the explanation, but I know gravitational force (and thus acceleration since f=ma) decreases after you go below the surface.
Behold! Science and religion in harmony, thank you Jebus.
Is that an intelligent RUclips comment? Has Hell frozen over?
I only have to say it once, STARKILLER Base in Space Engineers
Marek! you promised we could dig straight through!
underground hidden base to store stuff and ships
Pretty good idea but how would you acces it? Gow would you get the ships out/in?
I've watched a few of your videos on space engineers for a while now, and it makes me wanna play it again haha. I got bored of it and haven't played it in almost a year because I got kind of bored trying to upkeep my asteroid base with constant mining, and I was singleplayer which got boring and lonely. Though I shall try it now that it has planets =D
Aww. So you can't build an intra-planetary rail system like in Total Recall.
Jorne De Smedt haha. I love that movie
At the moment, you're better off using voxel hand to dig a hole through the planet. Its a pretty cool effect if you have a high speed mod on. Once you get the the center of the earth like planet, the screen goes white, black tears start to grow and eventually the screen goes black, and everything becomes lighter as you approach the surface of the other side of the planet.
how about your character drill tool?
Hey Aron, the reason for the decreasing gravity is that the part of the planet that is above you pulls you in its direction. So if u are in the middle u have equal amount of mass around u that pulls you in its direction so u wont feel gravity in the middle of a planet
Your warhead strategy is not unique to Space Engineers or a new idea - they've been doing that with TNT in Minecraft for years.
why? thats such a waste....
This is my favourite video ever
Gravity will be 0 at the bottom, that's how real life works too
Vinn_mobile Stupit? Earth is flat. Chemtrails!
Ok just kidding.
Gravity pulls you to the center of the mass. If you are in the center of a planet, incredible gravity from every direction would affect you. You will be simply compressed.
This must have taken a long time! Thanks
planetary annihilation: Ragnarok
dig to the other side with this thing, and make a quick-travel device to get to the other side of the planet
+Skythedragon Did you even watch the video? He already covered that... You can't do it.
I watched the vid without sound, cuz I was listening to music
+Skythedragon So you are trying to add to a conversation without having listened to the conversation?
Person A: Man, did you see the game last sunday?
Person B: Yeah! Did you know it was the player's birthday?
Person C: I like ketchup!
you are person C. Try to be person A.
A is a social kind of guy.
lol, love it!
Actually it does make sense that the gravity would begin to drop the deeper down you go. I believe vsauce had a video explaining travel through the center of the world, it's all mass based and once you go down so far you'll actually begin to slow up as you approach the core. This is because the further down you go the more mass is going to be above you, so once you get to the core (ignoring the pressures and heat) you'll probably just float there. Good job on the dev's part for thinking about that and doing their research.
Can you destroy a planet then? Like trim it as much as you can until you have a little asteroid
I imagine the amount of save data that'd generate would eventually halt your efforts
Hey, I don't know if you know this yet, but you can get to the center of the earth with voxel hands, and dig a tunnel just as wide. If you hold the button, you can usually fly straight ahead through the center at max speed. After the hole is cut, any thing can go straight through. It is 0 gravity at the center, and you can make really cool little orbits in the core with stones and things.
Alright i did it... well not really, but got far enough. you can go down with a ship till around 6.5k - 7k after that, items will disappear. you can still use your hand drill, but once you reach a point which is not to far from the "disappearing" point, your drill will start to auto-unequip. after that point you can spam the slot and have it work little by little, but then you get to a point at which you can't mine any more (my characters flashlight broke at this point too). This far down all you can do is use the creative mode voxel tools (spectator mode is recommended). and that my friends is how you drill through the planet, with voxel hands and a lot of time.
PS: i believe that at the core of the planet gravity is 0.05g-0.00g.
figuring out the actual gravity acting on a drill going to the core of a planet is quite complex.
There are three main considerations:
a) the gravitational force due to the cores mass will increase, since you lessen the distance to the baricenter
b) the deeper you got, the higher the amount of mass, which only contributes a small percentage towards downward force or even counteracts it, since it is "above" and "beside" you
c) a planets mass isnt distributed evenly throughout its volume.
So realistically speaking gravity would increase for a while, then drop until hitting perfect equilibrium once you reach the center of mass. All the way through youd experience fluctuations.
Haven't seen it mentioned yet, so here it goes: Lower gravity deep beneath the earth actually makes sense, because a lot of the planets mass will be above you, when you are deep underground. As gravity comes from mass, this means that the earth above you starts to get so massive, it pulls back at you, so you would actually feel less gravity deep below.
HAdn't watched teh vidoe yet but...*finally*!!
For anyone that's still curious: the gravity goes to 0.01g around the planets core (I assume 0 if you stand perfectly in the core) so you do just float around. Other than that there's nothing exciting down there. The lighting does go a bit strange because its day on one side and night on the other. And if you place a space station cube it seems to get a strange light in the corner that's right in the middle of the planet but I dont know what that is.
The gravity going down is actually realistic, when you get closer to the core the gravitational pull from the other side of the planet gets higher and in the middle it balances out. thus making you weightless. (Sorry for my bad English)
The gravity decreasing with great depth is wholly consistent with real life physics. At the center, there is a lot of pressure, but you are surrounded by mass in all directions, so you won’t accelerate in any direction. At the surface, there is only mass below, so gravity is higher.
the gravity going down makes perfect sense ,gravity doesn't pull you too the center but to mass ,once you go down far enough the gravity of the mass above starts pulling you up so if you got to the center you would feel the gravity from every point around you ,making zero gravity
"Preperations A through G were a complete and utter failure. Ladies and Gentlemen, I present to you, Preperation H" Dr. Evil
Anyone else interested in watching Aaron and his gang turning a planet or moon into a Coruscant-style planetary base? This could turn into another awesome series to watch them drill through a planet, making a secret empire underground that would lure traveler in and ..... MUAHAHAHA
The gravity decreases inside the planet because part of the mass is above you, cancelling the field partially. At the center, there is no gravity because there is equal mass on all sides and so the net effect is zero. Im actually happy the game takes this into account rather than treating the gravity as having a point source.
I've got to the center of earthlike planet, it took me 7 attempts to design a mole that works by gravity and not being damaged by bumps, no mods used. It's got to the center over 9 hours of drilling and got stuck in the center, because of zero gravity. It's actually was wobbling for about 10 meters up and down like a yo-yo.
This is a very Thunderbirds style operation.
Well now tazoo has a place to hide all of his...blunders. No proof it never happened. 👍;) tazoo
that was pretty awesome! thanks! :D
There are several reasons you would want to dig to/ through the core.
Several of those reasons involve Bases.
Some are Hangers and Ship Yards.
And Lets not forget about SECRET BASES.
And some good old fashioned Mining.
They have been added this "disappear" thing. In first time i have played with planets, i did drop warheads down to my hole, and i've been reaced the "center". It was the empty sphere with strange gravity in it - thats all i can remember
Hmm... The gravity dropping is what would actually happen as you get closer to the core of a planet, because of the fact that there is enough mass behind you to counter the gravity of the mass in front of you. I commend the devs for actually getting that to work.
Shaft deep into the lithosphere? (puts sunglasses on) You can dig it!
@LastStandGamers
it has to do with atmospheric pressure. as you dig further down, the pressure of the atmosphere is weighing down on you less. So it's not necessarily that the gravity has gotten lower. It's getting higher. but now the earth is holding up the atmosphere, instead of your shoulders, as an example.
The furthest down we drilled so far to my knowledge is 12066m (kola peninsula on russian soil), reaching 180°C on the bottom.
Studies revealed through meassuring weight that gravity below ground is actualy lower as the mass above increases.
Just build a base right underneath the core and bam! you are almost invincible, baby!
Is this a physics range issue, or could you drill an arc around the core. That, in and of itself, would still be an amazing feat.
7km down... you could build one hell of an underground base with that!!! And being so deep, orbital bombardment would take forever to blast through into the base :D
Just out of curiosity, have you considered going around to the opposite side of the planet, and doing the same thing to see if you can somehow make your tunnels meet up in the middle? What about going around the core? IE: Dig sideways and down until you've marked out the boundary of where you can no longer dig?
I have gone much deeper. I think maybe it didn't work for you b/c you were creating the bombs with the admin tools. Maybe you should have tried spawning your drilling ship at the bottom of the hole it would have kept going deeper. I'll have to put up a video of my setup. Very nice drill you have there btw. :)
Step 2: mine off the entire 7km deep layer of a planet's surface. Then see if what's left can be affected. If not then build your base just slightly above the surface and let them attack you with warheads and such, and dodge. You'd have no problems with explosions if they are absorbed. It would be interesting, keeping this in mind, to test depths possible on constructed items, compared to objects moving into the anihilosphere from further out. Would you be able to construct something in that area, what would happen to projectiles from guns, rather than constructed 'warheads'? A lot can be done to see what is possible with this zone you've found.
In one of the trailers for Space Engineers they digged throw the whole planet with a drilling ship.
It's probably to delete rogue ship parts that clip through the terrain upon impact at high speeds. I've noticed this happens as new grids are formed by a destroyed ship, and the "new" grids sometimes pop through the terrain. Since the gravity will pull everything to it, it makes sense to make a "kill zone" should the garbage collection system miss some grids that have clipped through the terrain.
To answer your question, yes gravity decreases as your depth increases (on Earth anyways). Eventually your gravity would be 0 at the core, due to a net gravitational force of 0, as all forces begin to point outwards (from varying masses on the surface/away from the core) and thus, zero gravity
Love his outro music so much.
I have been to the center of a planet... Its actually really easy. Set up a macro on your mouse or keyboard that perpetually holds down the right mouse button. Then, in creative equip voxel hands. Hover over the ground looking straight down, press the RMB macro to delete the ground in front of you. Then you just turn off your inertial dampeners and walk away and let gravity do the work. It takes like 5 minuets or something like that to get to the bottom but it's pretty cool because there is a tiny anti gravity zone in the middle of the planet!
Building a underground base at that depth would certainly keep you safe.
Only you would have required to build a lift system to get people down. and it would probably require a stair case that reached the surface and was hidden in a cave in case of emergencies.
Had a friend fall from orbit as an astronaut and we had faster speed mod. He hit the surface so fast he phased through the ground and his character flew toward the core of the planet. Then he literally began to orbit the planet from within. He was flying a few kilometers under the surface, perfectly orbiting the core of the planet at max velocity. Turning his jetpack with dampeners on had absolutely no effect because he was going at least 5 km/s. I was on Mars and could see his player transmission quickly bounce back and forth from side to side as he flew around. That was an interesting rescue attempt. Had to give him admin so he could teleport out. ;
Physics lesson: All gravitational forces balance/cancel each other out at the center so you end up with 0 gravity at the gravitational center of a planet, assuming you can get there.
The gravitational center of a planet may be different then the geographical center because a gravitational force in one direction may be stronger than a g-force in another direction.
you can place some gravity generators along the tunnel sides to mantain the ship centered. Or wheels + suspension. Even a system that can balance the ship perfectly vertically (with gravity generators) would be enough to avoid collisions
idk how many of the comments you guys read, but i have a cool idea. What would happen if you used some sort of level editor to delete the whole planet except the middle part that deletes everything it touches? Would the gravitational field still be present? If so would that basically make the planet a space engineers black hole?
have fun getting out with drill tool, have fun getting out xD hydrogen
Can totally see the developers adding a molten core to explain that deletion process.
A purpose I might see is having an enormous hangar near a planet's core, either for shielding it with the ground, invading someone's base from below, or just for the cool factor. Imagine jumping inside a planet!
Better way to make it to the center: Go on a server with high ping and some speed mods, spawn in suit, and use your jetpack to increase downward acceleration. Once you've clipped through the planet, just remove your helmet and let gravity do the work.
Nice, I will definitely be using this to magically destroy trash. lol
Aaron, now with this info, what if you dig, straight down, on the side of a planet, like, 7km north of the equator and dig down 'till you pop out 7km south of the equator? would that allow for a 14 km tunnel to ship goods through?
How far from the equator could you go to still have that work? (assuming it works at all)
It's cool that they made that when you dig into the planet, the gravity decrease. That's realistic in the way that you're attracted by the center of the planet, but also by the rock/dirt above you. So as you get closer to the center, the gravity decrease cause of the matter attracting you from all angles, to the point where the gravity reach the 0 level cause your at the center of the planet.
