Why wouldn't you say constant stuff. They're just a bunch of numbers which when calculated resulting in one number, this number says very little scientificly about a formula
+JustJason it's justified because "constant stuff" doesn't change the nature of the curve, a linear function times a constant is still a linear function. Linear transformations can be done at the beginning and the very end to make sure things are in agreement (e.g. the unit system), but don't really matter when it comes to finding a strategy to reason about the equation, in that respect they serve only to distract and potentially introduce calculation errors.
Sorry if I ask something incredibly dumb but shouldn't the extremely high pressure cancel the high temperature out? Or at least close enough. Your body would boil and evaporate if at sea level pressure.
That's not used as a factor in the video though, temperature doesn't matter because there is no air to transfer it. All factors aside from gravity (and all relevant factors to that such as density) and time are excluded for the purpose of the calculation.
+Penny Lane No it's pretty easy... i'm in last grade in france jsut before my graduation and all the physics calculations you see that here already and it's pretty simple. the only long part must be gathering the informations about density and stuff, after that its just aplying formules and math magic :)
HolyBookProductions I'm not saying it's hard. I'm just saying it'll take you longer than 40 minutes to do the non-simplified calculations. And yes, Aditya Khanna has a point in that I don't actually suggest jumping into a tunnel through the Earth that doesn't exist to save time. Primarily because most stop watches don't cope well with the pressure and the heat.
Penny Lane I doubt stopwatch would be a problem (it's least of our concern). There can be two people on opposite sides, with stopwatches. And actually, it takes less time for a pro physicist!
Thank you for this video! I love how you explain the concepts of physics, but to see the maths that goes behind it is very interesting, and something that I believe is lacking in many science-based RUclips videos. I know many may quickly lose interest when the maths takes over but I know there are many people out there, like me, who enjoy it. So please make more of these videos!! :)
I'm a black hole. I suck up all the information that I encounter, but hardly ever let anything exit my mind. It only happens in the form of Hawking radiation, when one of a pair of entangled particles (like your comment and my reading of it) enter my mind. Sometimes I explode and create new galaxies filled with bullshit like this.
+Mandragara He sneaked that in under the radar by skipping straight to the solutions of a simple harmonic oscillator :p. You would need to do the calculus in order to get those solutions, or to otherwise solve for the travel time.
+ninjafruitchilled as many wise people have said the best scientists just steal other peoples work. why mess about with calculus when someone has already done it for you
+Sam Winton Well the main reason would be to properly understand how it works. Also in this case it isn't very hard. But it would be a bit too far beyond what you could expect an audience to follow in a RUclips video, so it is clear enough why he didn't do it.
+ninjafruitchilled fair point. Ive done A level physics so the video was pretty simple to me. If calculus had been included i would have been screwed 😂
I don't get why we can cancel out everything that's obove us in the "shaved earth" model: the gravitational force depends on how far you're away. That means that if I fall straight into the hole, the part above me attracts me much more than the part opposite the earth pulls me down, because one is much closer than the other -> smaller radius, more attraction (G*m1*m2/r^2). Is my question clear?

It is also worth mentioning that, assuming Earth has constant density, it doesn't matters if you are falling through the center of the earth. You can go a little bit sideways, it would be also the same time. Or even completely sideways. Like trying to dig directly from London to Paris. If there is no friction with ground and if you will just jump in the hole, you will also arrive in ~42 minutes
Loved this video! Please do more with actual physics calculations in it (the speed is fine because those of us that actually want to go through the math can just pause!) definitely my favorite of your videos just for that!
A pendulum is simply a weight on a string or arm that is allowed to swing freely. Like a clock's swinging weight, or a swing in a playground. They are pretty simple to calculate how they behave, and are a good introduction to things that constantly change speed and oscillate, so they tend to be found in beginner physics classes.
I have seen completely serious posts display stunningly inept questions before, so I assume people are serious when they ask a question. If they are a poe, then okay. The next person to see the thread that doesn't actually know gets the answer for a question they don't have to ask anymore. And I cure my boredom for a few more minutes.

Great Video!! You guys should do more videos with the math being worked out... It might not please everyone, but it certainly adds a lot more value to the content.
Nope, everything he did was perfectly legit. Albeit, he took some mighty unrealistic assumptions to get to those points. However, it's an unrealistic question to begin with so it's all good.
If we were to include air and subsequently include terminal velocity in our maths, you would be unable to reach the other side. You'd reach the centre, then fall so far as to decrease your velocity from its terminal state to zero, at which point you then approach teh centre again. Eventually, you'd run out of momentum and be suspended at that central point, whereupon the intense heat would cook you inside out like a develled egg. Or a large turkey. Or basically any foodstuff that experiences such.
Mind shatter ... it's not possible to drill a hole through the earth from pole to pole since that would seperate the planet but gravity would simply pull the pieces together again ... not worth it ppl :/
+We-Play !-Play anything ! no it wouldn't, it would just be like a weirdly-shaped doughnut, and they don't fall into two pieces :P the diagram in the video is 2D, so I can see where the confusion came from :)
+We-Play !-Play anything ! But it's not cutting the world in half, as it looks in the 2 dimensional drawing, it's merely a hole dug through the centre, like a doughnut. The world probably wouldn't collapse on the holes if it was only big enough for you body. Also this video was entirely theoretical.
+SbAsAlSe HONRe Ugghh thanks for the explanation I forgot to account for that ... but wouldn't the metal inside spill out ... or will it stay in place due to the forces cancelling out on it ?
That's pretty awesome. That would be a really cool trip to step into a hole, and step out on the other side of the Earth 38 minutes later. Just make sure you don't miss the stepping out part. And, I guess, don't touch the sides.
Also bring a air tank, and pretty heavy duty insulation, and a space suit. Otherwise you'll suffocate, melt from the heat, and die from the hard vacuum. Also maybe bring an audiobook because that would otherwise be a boring 38 minutes.
I think its safe to assume the hole is self contained with impossibly resillient walls - this is a 'what if' you couldn't achieve in reality because a straight up hole would just instantly fill up with lava.
Awesome video, thanks! Just so long as no one turns around and says "why haven't we built this yet?!". I've had to explain to someone that this is not pragmatic, and never will be in the conceivable future. We're talking about drilling a hole through the mantle, through the core, through everything that idles at incredible pressure and heat. We and our perceivable future selves cannot deal with that; we can't even dig more than a few km through the crust before our best equipment starts to break down. And our tunnel has to endure the internal forces of the molten core not only squeezing it, but also moving around inside while the continents are moving at the surface (albeit both at a geologic pace, cm per year; but there's no super-ancient society that built tunnels through the earth for us to ride). And the Coriolis effect makes the ride down difficult. And then you need to survive the heat and pressure during the ride, not just the equipment. And.... Okay really there's no point enumerating further. But sometimes people read sci-fi stories and think they're an authority on the subject. So yea it's not realistic. Same with pushing the end of a pole that reaches between planets to produce faster-than-light communication... just no.

do you guys forgot the days where jake (from vsauce 3) got a lot of hate comments because he uploaded a video with the same topic/lines as of cgp grey (yes im aware that in this case minutephysics uploaded it several months earlier while cgp grey uploaded it in a few days hence the quality/editing time for vsauce 3 to copy grey's video is inhumanely fast. hence vsauce 3 is innocent) why did they think vsauce 3 plagarized? both vsauce 3 and cgp grey used the most common/mind boggling/ sequence/ choice of words/ lines (the sleeping) they could find/come up with while surfing through the internet. few points to consider 1.) the ideas/words/common lines of this topic (just like the sleeping/death due to teleportation from vsauce3 and cgp grey's case) used in this minutephysics video can be found on the internet. should michio kaku file for them for stating his idea of death due to quantum teleportation (assuming michio kaku is the first eventhough there are others before him said the same thing about teleporters) 2.) taking out the most common lines found in the internet on both videos guess is that life noggin got the idea from minutephysics and work from there. should life noggin be getting hate for being inspired to minutepysics? it could be true that he copy pasted minutephysics but we dont have enough information to know. innocent until proven guilty it is unfair for a guy to get a lot of hate with not much evidence. he is guilty if he does this several times before/ again in the future. 3.) should the several "honest anime trailers" channels should be getting hate because they obviously got the IDEA AND FORMAT from screen junkies 4.) matthew santoro got several hate because he used a particular site's and basically copy pasted it. his originality is the background and jokes. the hate cooled down because he couldnt possibly made up the facts. The problem is he got it from few sites. 5.) should react channels get hate because they popped up with the success of fine bros? 7.) should kurzgesagt get hate for getting ideas from the internet? kurzgesagt: "Genetic engineering will change everything forever" with designer babies on the video posted 2 weeks ago. life noggin: "will genetic modification change humans" life noggin also says the phrase "designer babies" IN HIS OWN VIDEO POSTED 2 MONTHS AGO. SO SHOULD KURZGESAGT get hate? (no since designer babies is a phrase for genetically modified babies. but its uncommon thing to say since neither kurzgesagt nor life noggin knows about the "designer babies" phrases since they are not biologists. obviously life noggin got it from scientific articles/videos regarding cas 9/crispr FROM THE INTERNET) {Then kurzgesagt POSSIBLY saw life noggin's video and start from there (sounds familiar?) they COULD'VE get the research/editing done in 2 months with a channel that big.} (also similar art style on both sides although both are not famous at the time on their first year in youtube cant see who "copied" first could be a coincidence) NOTE: im not saying kurzgesagt's team plagiarized i said they couldve and it connects to #8. 8.) MOST SUCCESSFUL SCIENCE CHANNELS GET IDEAS FROM THE INTERNET TO INCREASE ENJOYMENT/PASS IDEAS EASIER. I HEAR COMMON THINGS ON THE SAME TOPIC BETWEEN SEVERAL SCIENCE CHANNELS (eg. the death due to teleportation is a good start of philosophical ideas {michio kaku} and makes the video more exciting) ITS A COMMON THING TO DO IN SCIENCE CHANNELS. (SO NEXT TIME JUST ADD THE SOURCES BELOW)
Here's something that ive been thinking about for a long time now: As you fell through the Earth, due to gravity slowing you after passing the core and now working against you instead of with you, wouldn't that resistance cause you to not quite reach the other side? as a result, you would just fall back towards the Earth's core and repeat the process, now with less initial height, thus less force to propel you past the core. so my question is, after youve repeated the process many times, and youve passed the core many times, with a decreasingly less maximum distance from the core than the last pass, what would happen once you were only falling a few feet each pass? and what would happen after that? would you just float idlely at the center of the Earth, as there is no force pulling you downwards, and equal force pulling you outwards from all directions? Or would you either be crushed under the pressure or be streched in every direction simultaneously from the gravity encircling you, and balloon out and be torn apart?
The force of gravity cancels in all directions, meaning there is 0 net force on your body and you just float there. It would be identical to being in empty space. That would only happen if there was something to slow you down though. In the video he assumes there's no air in the hole, so you would actually lose no energy to air resistance and just go back and forth forever. A linear orbit.
@pyropulse nobody likes people who are a prick for no reason about a silly hypothetical concept. Imagine having a superiority complex over something that is a stupid idea to begin with. I wrote that comment when I was 16, do you really think the law of conservation of energy or other laws of physics were on my mind at the time, or that I really even had a good grasp on what those are?
+Euan MacDonald year 7 was about when i started doing this kind of stuff in maths classes, so it makes sense. didn't have to piece together stuff this way until year 10 or 11 physics but all of the parts were already well taught in years 7 and 8.
I love this. It's pretty logical, expect the fact that to drill a hole through the earth, you'd have a bit of a problem, since the two parts will pull/push you in a non spheric way, which makes it a hell of a lot more difficult.
If the radius of the earth doesn't matter, then how big of an earth-density object could you still fall through/around in forty-two minutes, before the light-speed barrier became a problem? (That's assuming the object you were falling through/around didn't collapse under its own gravity into a black hole or something.)
This is assuming classical physics. Obviously, things break down when you reach high velocities. In that case, we'd need to use calc and Einstein's equations.
Also, you can build a frictionless, straight-line tunnel between any two points on the surface and the travel time will always be the same. It doesn't need to go through the centre of the planet.
had the earth bee flat then as we'd have moved across the centre of the earth we'd have started to sort of bulge as we'd gradually move towards the other pole until our height would become extremely close to 0 (but not 0) -RAhDuin
I would like to see the function of g. Or is the "pendula"-equation already the solution to this differential equation? It wasnt really clear, whether you used g as g(t) or g(R)...
i am mainly interested in finding a guy smarter than me as a love interest. but i think this is too smart for me. the main thing i got from this video is that i found the threshold of when my brain no longer can compute.
I think we'd be under so much pressure and temperature that we'd turn into impure diamonds by the time we come out on the other side. Well that's my optimistic thought :D
+Prince_q8cool I mean if we're taking stuff like that into account you can probably assume that during your travels the two halves of the Earth will attract themselves together again and squish you, so I imagine that's a bigger problem
3:18 I mean if you think about it the radius of the earth does factor in because density is mass divided by volume in volume is directly proportional to radius cubed
I hate that you never involve calculus in these videos, I get that a good amount of the audience won't understand it, but hopefully that curiosity will lead them to doing self study to learn calculus and understand what you did in the video.
LOL calculus self study. Alright bud. The majority of his viewers are still in middle school and high school so there is no way that they would even have a chance to understand it. A select few would, definitely, but that's not the target audience of this channel. You're thinking from a purely mathematical standpoint, but this is his job. He's gotta think about it from a business standpoint. The easier something is to understand, the more viewers will watch it.
Calculus is a great way to understand these things, but as Jason said, it will just deter people from watching his videos. In "A Brief History of Time", Stephen Hawking said that for every equation he puts in the book, the sales would decrease by half. So he only ended up putting one, just like Henry didn't use calculus in his video.
I self studied calc and I agree with daveed. He is thinking from a purely mathematical standpoint but that's what this channel is about. maybe he can make a new channel called 2-minute physics.
I'm not sure why you're being so dismissive about people understanding calculus - fundamentally, calculus is pretty simple. Derivatives are rates of change, integrals are areas under a curve, the two things are opposites, and everything else is just the working out. And besides, some people learn calculus in high school. I learned up to Calculus BC this past year (junior/11th grade).
+TristanBomb I started learning calculus on my own as a freshman in high school, and I'm still working on it in 10th grade. I didn't say it was impossible to understand, but most people who took it in college hated it and they probably don't want it in a RUclips video that they casually watch for light education

Ah yes, terminal velocity, slow and boring.
in an endless black tube of nothing but temperature variation for more than half an hour? there's not even air in there and the sensation of falling only applies while youre still accelerating at a noticeable rate.
after a few minutes you wont feel, see or hear a thing.
Terminal velocity is something caused by air friction, which is taken out of the calculations like he said at the beginning of the video
Yes, ok. you are TECHNICALLY correct. happy? :P
jamham69 Yeah, you wouldn't feel, see, or hear a thing. You also wouldn't be alive.
If you made the tunnel, allowed time to fill it with air, then jumped in, air resistance would limit your acceleration to terminal velocity. But after passing the center of the Earth, your momentum would be competing against gravity and wind resistance. You'd never make it to China.

well ... 38 m and 6 seconds ... just 4 minutes less :P ... (or better , 3,54)
so THAT's the ultimate question! The question to life, the universe and everything!
Ah... a sweet reference
Oh come on, be honest now. It took you much longer to calculate all this stuff than 38 minutes and 6 seconds.
If you say, more time, then I'd say much less death.
+Penny Lane No it's pretty easy... i'm in last grade in france jsut before my graduation and all the physics calculations you see that here already and it's pretty simple.
the only long part must be gathering the informations about density and stuff, after that its just aplying formules and math magic :)
HolyBookProductions I think she was sarcastic.
HolyBookProductions I'm not saying it's hard. I'm just saying it'll take you longer than 40 minutes to do the non-simplified calculations. And yes, Aditya Khanna has a point in that I don't actually suggest jumping into a tunnel through the Earth that doesn't exist to save time. Primarily because most stop watches don't cope well with the pressure and the heat.
Penny Lane I doubt stopwatch would be a problem (it's least of our concern). There can be two people on opposite sides, with stopwatches.
And actually, it takes less time for a pro physicist!
Thank you for this video!
I love how you explain the concepts of physics, but to see the maths that goes behind it is very interesting, and something that I believe is lacking in many science-based RUclips videos. I know many may quickly lose interest when the maths takes over but I know there are many people out there, like me, who enjoy it.
So please make more of these videos!! :)
Fun fact: Mathmagical dust settling causes the creation of black holes.
i didnt have fun :(
Me neither :(
+Cognito Speaking of black holes, as a thing, they don't truly exist; they are merely intensely warped space//time around a singularity.
I'm a black hole.
I suck up all the information that I encounter, but hardly ever let anything exit my mind. It only happens in the form of Hawking radiation, when one of a pair of entangled particles (like your comment and my reading of it) enter my mind.
Sometimes I explode and create new galaxies filled with bullshit like this.
Quintum Anarchy
Sorry I don't suck up massless things. I'm a black hole, not the Higgs field.
My physics teacher had us explore this question in high school, like this video he really made learning fun and I wish more teachers were like that.
Good thing I don't go to school :D
This seems odd to do without integral calculus
+Mandragara He sneaked that in under the radar by skipping straight to the solutions of a simple harmonic oscillator :p. You would need to do the calculus in order to get those solutions, or to otherwise solve for the travel time.
+ninjafruitchilled as many wise people have said the best scientists just steal other peoples work. why mess about with calculus when someone has already done it for you
+Sam Winton Well the main reason would be to properly understand how it works. Also in this case it isn't very hard. But it would be a bit too far beyond what you could expect an audience to follow in a RUclips video, so it is clear enough why he didn't do it.
+ninjafruitchilled fair point. Ive done A level physics so the video was pretty simple to me. If calculus had been included i would have been screwed 😂
+ninjafruitchilled I was kind of ridiculously happy when he skipped the (double?) integration though.
Please make more videos like this one, it was really interesting and I loved how you showed all of the calculations.
I'd rather jump honestly...
I know right.
That sounds so morbid out of context.
In context too, since you'd die if you jumped in the hole.
LMAO, Perfect comment
I don't get why we can cancel out everything that's obove us in the "shaved earth" model: the gravitational force depends on how far you're away. That means that if I fall straight into the hole, the part above me attracts me much more than the part opposite the earth pulls me down, because one is much closer than the other -> smaller radius, more attraction (G*m1*m2/r^2). Is my question clear?
I can't wait to understand any of this when I take physics class.

Bruh u still wont get it
That's cute.

Of course it takes 42 minutes to fall through any sphere. You don't have to do any calculations to figure that out.
So it takes 42 minutes to fall through a 30 feet sphere?
+nimbuzz obviously
+nimbuzz If its density is that of the earth yes. Keep in mind a 30 feet sphere wouldnt exert much gravitational pull on you tho. Math is neet

If no other force is present, yes.

I lost you at "I recently received this question"
It is also worth mentioning that, assuming Earth has constant density, it doesn't matters if you are falling through the center of the earth. You can go a little bit sideways, it would be also the same time. Or even completely sideways. Like trying to dig directly from London to Paris. If there is no friction with ground and if you will just jump in the hole, you will also arrive in ~42 minutes

The fuck is a penualamum thank goodness you put that cat in the parabola because I would have been so lost
A pendulum is simply a weight on a string or arm that is allowed to swing freely. Like a clock's swinging weight, or a swing in a playground.
They are pretty simple to calculate how they behave, and are a good introduction to things that constantly change speed and oscillate, so they tend to be found in beginner physics classes.

If we were to include air and subsequently include terminal velocity in our maths, you would be unable to reach the other side. You'd reach the centre, then fall so far as to decrease your velocity from its terminal state to zero, at which point you then approach teh centre again. Eventually, you'd run out of momentum and be suspended at that central point, whereupon the intense heat would cook you inside out like a develled egg. Or a large turkey. Or basically any foodstuff that experiences such.
Mind shatter ... it's not possible to drill a hole through the earth from pole to pole since that would seperate the planet but gravity would simply pull the pieces together again ... not worth it ppl :/
+We-Play !-Play anything ! Also there is molten metal and stuff in the middle...
+We-Play !-Play anything ! no it wouldn't, it would just be like a weirdly-shaped doughnut, and they don't fall into two pieces :P the diagram in the video is 2D, so I can see where the confusion came from :)
+We-Play !-Play anything ! But it's not cutting the world in half, as it looks in the 2 dimensional drawing, it's merely a hole dug through the centre, like a doughnut. The world probably wouldn't collapse on the holes if it was only big enough for you body. Also this video was entirely theoretical.
+SbAsAlSe HONRe Ugghh thanks for the explanation I forgot to account for that ... but wouldn't the metal inside spill out ... or will it stay in place due to the forces cancelling out on it ?
Thank you! Great content and superb delivery, loved the triple shot of the stick men falling!
That's pretty awesome. That would be a really cool trip to step into a hole, and step out on the other side of the Earth 38 minutes later. Just make sure you don't miss the stepping out part. And, I guess, don't touch the sides.
Also bring a air tank, and pretty heavy duty insulation, and a space suit. Otherwise you'll suffocate, melt from the heat, and die from the hard vacuum. Also maybe bring an audiobook because that would otherwise be a boring 38 minutes.
Jacob Siemons haha yeah, that too
I think its safe to assume the hole is self contained with impossibly resillient walls - this is a 'what if' you couldn't achieve in reality because a straight up hole would just instantly fill up with lava.
+elevown but the earth would also probably stick back together cause of the gravity I guess

Awesome video, thanks!
Just so long as no one turns around and says "why haven't we built this yet?!". I've had to explain to someone that this is not pragmatic, and never will be in the conceivable future. We're talking about drilling a hole through the mantle, through the core, through everything that idles at incredible pressure and heat. We and our perceivable future selves cannot deal with that; we can't even dig more than a few km through the crust before our best equipment starts to break down. And our tunnel has to endure the internal forces of the molten core not only squeezing it, but also moving around inside while the continents are moving at the surface (albeit both at a geologic pace, cm per year; but there's no super-ancient society that built tunnels through the earth for us to ride). And the Coriolis effect makes the ride down difficult. And then you need to survive the heat and pressure during the ride, not just the equipment. And.... Okay really there's no point enumerating further. But sometimes people read sci-fi stories and think they're an authority on the subject.
So yea it's not realistic. Same with pushing the end of a pole that reaches between planets to produce faster-than-light communication... just no.
I just realized I'm dumber than I first thought.
That is an important step towards getting smarter. Good for you :)

Pro tip: make sure no one else jumps in the other side during your fall
do you guys forgot the days where jake (from vsauce 3) got a lot of hate comments because he uploaded a video with the same topic/lines as of cgp grey (yes im aware that in this case minutephysics uploaded it several months earlier while cgp grey uploaded it in a few days hence the quality/editing time for vsauce 3 to copy grey's video is inhumanely fast. hence vsauce 3 is innocent)
why did they think vsauce 3 plagarized?
both vsauce 3 and cgp grey used the most common/mind boggling/ sequence/ choice of words/ lines (the sleeping) they could find/come up with while surfing through the internet.
few points to consider
1.) the ideas/words/common lines of this topic (just like the sleeping/death due to teleportation from vsauce3 and cgp grey's case) used in this minutephysics video can be found on the internet. should michio kaku file for them for stating his idea of death due to quantum teleportation (assuming michio kaku is the first eventhough there are others before him said the same thing about teleporters)
2.) taking out the most common lines found in the internet on both videos
guess is that life noggin got the idea from minutephysics and work from there. should life noggin be getting hate for being inspired to minutepysics? it could be true that he copy pasted minutephysics but we dont have enough information to know. innocent until proven guilty it is unfair for a guy to get a lot of hate with not much evidence. he is guilty if he does this several times before/ again in the future.
3.) should the several "honest anime trailers" channels should be getting hate because they obviously got the IDEA AND FORMAT
from screen junkies
4.) matthew santoro got several hate because he used a particular site's and basically copy pasted it. his originality is the background and jokes. the hate cooled down because he couldnt possibly made up the facts. The problem is he got it from few sites.
5.) should react channels get hate because they popped up with the success of fine bros?
7.) should kurzgesagt get hate for getting ideas from the internet? kurzgesagt: "Genetic engineering will change everything forever" with designer babies on the video posted 2 weeks ago.
life noggin: "will genetic modification change humans" life noggin also says the phrase "designer babies" IN HIS OWN VIDEO POSTED 2 MONTHS AGO. SO SHOULD KURZGESAGT get hate? (no since designer babies is a phrase for genetically modified babies. but its uncommon thing to say since neither kurzgesagt nor life noggin knows about the "designer babies" phrases since they are not biologists. obviously life noggin got it from scientific articles/videos regarding cas 9/crispr FROM THE INTERNET) {Then kurzgesagt POSSIBLY saw life noggin's video and start from there (sounds familiar?) they COULD'VE get the research/editing done in 2 months with a channel that big.}
(also similar art style on both sides although both are not famous at the time on their first year in youtube cant see who "copied" first could be a coincidence) NOTE: im not saying kurzgesagt's team plagiarized i said they couldve and it connects to #8.
8.) MOST SUCCESSFUL SCIENCE CHANNELS GET IDEAS FROM THE INTERNET TO INCREASE ENJOYMENT/PASS IDEAS EASIER. I HEAR COMMON THINGS ON THE SAME TOPIC BETWEEN SEVERAL SCIENCE CHANNELS (eg. the death due to teleportation is a good start of philosophical ideas {michio kaku} and makes the video more exciting) ITS A COMMON THING TO DO IN SCIENCE CHANNELS. (SO NEXT TIME JUST ADD THE SOURCES BELOW)
Here's something that ive been thinking about for a long time now: As you fell through the Earth, due to gravity slowing you after passing the core and now working against you instead of with you, wouldn't that resistance cause you to not quite reach the other side? as a result, you would just fall back towards the Earth's core and repeat the process, now with less initial height, thus less force to propel you past the core. so my question is, after youve repeated the process many times, and youve passed the core many times, with a decreasingly less maximum distance from the core than the last pass, what would happen once you were only falling a few feet each pass? and what would happen after that? would you just float idlely at the center of the Earth, as there is no force pulling you downwards, and equal force pulling you outwards from all directions? Or would you either be crushed under the pressure or be streched in every direction simultaneously from the gravity encircling you, and balloon out and be torn apart?
The force of gravity cancels in all directions, meaning there is 0 net force on your body and you just float there. It would be identical to being in empty space. That would only happen if there was something to slow you down though. In the video he assumes there's no air in the hole, so you would actually lose no energy to air resistance and just go back and forth forever. A linear orbit.

This is a pretty simple video. actually.
I love this. It's pretty logical, expect the fact that to drill a hole through the earth, you'd have a bit of a problem, since the two parts will pull/push you in a non spheric way, which makes it a hell of a lot more difficult.
In my net math class, I am going to use "constant stuff" as a variable.
*Next
~My constants aren't and variables don't~
If the radius of the earth doesn't matter, then how big of an earth-density object could you still fall through/around in forty-two minutes, before the light-speed barrier became a problem? (That's assuming the object you were falling through/around didn't collapse under its own gravity into a black hole or something.)
If the object would accelerate you up to almost-the-speed-of-light speeds the *fallen distance* would actually decrease. That's my guess.
This is assuming classical physics. Obviously, things break down when you reach high velocities. In that case, we'd need to use calc and Einstein's equations.
The question was how long it would take to fall through earth
1 minute in he begins talking about shaving earth
Also, you can build a frictionless, straight-line tunnel between any two points on the surface and the travel time will always be the same. It doesn't need to go through the centre of the planet.
But when speedy thing comes in, speedy thing comes out
I understood that reference!!
The math is melting my brain, I don't get it
What he said. A math equation is just a machine on paper. You follow a simple set of instructions and the machine does almost all of the work for you.

No, the Coriolis effect is cancelled because you go from north to south.
Ofcourse not, you'll burn and turn into gas and carbon*. Btw you'll be slowed by air resistance so you won't make it to the other side.

+Prince_q8cool I mean if we're taking stuff like that into account you can probably assume that during your travels the two halves of the Earth will attract themselves together again and squish you, so I imagine that's a bigger problem

I hate that you never involve calculus in these videos, I get that a good amount of the audience won't understand it, but hopefully that curiosity will lead them to doing self study to learn calculus and understand what you did in the video.
LOL calculus self study. Alright bud. The majority of his viewers are still in middle school and high school so there is no way that they would even have a chance to understand it. A select few would, definitely, but that's not the target audience of this channel. You're thinking from a purely mathematical standpoint, but this is his job. He's gotta think about it from a business standpoint. The easier something is to understand, the more viewers will watch it.
Calculus is a great way to understand these things, but as Jason said, it will just deter people from watching his videos. In "A Brief History of Time", Stephen Hawking said that for every equation he puts in the book, the sales would decrease by half. So he only ended up putting one, just like Henry didn't use calculus in his video.
I self studied calc and I agree with daveed. He is thinking from a purely mathematical standpoint but that's what this channel is about. maybe he can make a new channel called 2-minute physics.
I'm not sure why you're being so dismissive about people understanding calculus - fundamentally, calculus is pretty simple. Derivatives are rates of change, integrals are areas under a curve, the two things are opposites, and everything else is just the working out.
And besides, some people learn calculus in high school. I learned up to Calculus BC this past year (junior/11th grade).
+TristanBomb I started learning calculus on my own as a freshman in high school, and I'm still working on it in 10th grade. I didn't say it was impossible to understand, but most people who took it in college hated it and they probably don't want it in a RUclips video that they casually watch for light education
