To stabilise the spacecraft, couldn't you just force it into a constant freefall into the black hole, that you counterbalance with the Halo Drive? Using something like an anchor on a long string that is much closer to the black hole.
Damn I think you got it! Yes I don’t know why I didn’t think of this because I have a related paper in draft on a similar idea for the Sun. The outward force of the halo subtracts partially off the inward freefall acceleration which essentially hacks Keplers Third Law making the black hole appear lower mass. See arxiv.org/abs/0901.1606
Uhh, did I win something? :D I was hoping the same thing would work for a space elevator. having an electromagnet that gets pushed outwards by earths magnetic field and thereby stabilising the elevator. But I guess that is a bit more complicated.
This channel is incredible. I recently found this community and I love it. Such a peaceful vibe, I listen at night before bed to help me relax and have an existential crisis lol
Gosh, I LOVE watching your videos, because you are a Scientist who is not embarassed to speculate imaginatively about the cosmos and interstellar travel, and yet you always do so by “sticking to the rules”, and imagining realistic possibilities!
Found your channel a few weeks back... And I'm watching several episodes a day... And is a fantastic balance of astronomy/physics/math /theoretical science... Highly underrated channel too... Great work @cool Worlds.
Because ,as so technically and scientifically interesting it is this concept, and someone probably could use or create ideas from this to something different,it fails in practicallity. The closest black hole is at 1560 light years. And,to make you an idea,all Star Trek empires, are in a cluster not longer than 1600 light years in diameter.. Most Dune saga,with thousands of worlds involved, having to fold space in order to function, occurs at tens of ligths years of our solar systen,and between each of them. The closest star to to ours is 'just' 4,2 light years away So...using his system would be like...walking thousands of miles from your city,in order to take a jet ...to go and see your grandma...instead of walking to her house,just a few miles ,in the same city you live in. By the time It wouldn't be impractical to have to travel to the nearest black hole to use It,that would be just ,maybe, a "cheaper way" to go even far,far away
@mryellow6918 this is my guess from a basic look on Wikipedia so don't take me to seriously. I'm just a stoner from Canada. Micro black holes disappear almost instantly and being micro, the large size of the laser would only lose most of its energy, since only a microscopic amount of space time is being curved, losing most of the laser into deep space.
just found this channel, as many others probably have. definitely not a science student, not by any sense of the word; but the clarity and enthusiasm you bring to the topics you do is immensely elucidating, regardless of the subject. bonus is that as you're a professor that produces and interacts with actual validated research papers, citation and credibility of knowledge is much less of a potential issue. subscribed, interested to see what content comes in the future :)
Thanks for tuning in! Yes sadly being a professor means I can’t churn out videos every week but we have a bunch of great videos planned over the next few months!
Newbie here, as well. Amazing information here. Subscribed after watching 1 of his videos. Great comments, too. No hateful arguments. Nice place to be.
Yes, I agree. It's all very well watching an interesting theory video BUT without having the least idea about the producer/s of said video, you've no idea if it's just some nutjob in basement bedroom wanting attention or someone who actually has a clue which is the case here. Like you, I'm not a science student in any sense of the word either.
I love seeing the inclusion of images and clips from some of my favorite games, those being Stellaris and SpaceEngine! A lot of my own ideas regarding interstellar travel stemmed from game mechanics.
I don't have any physics related education what so ever but man do I love watching these videos! Very very interesting stuff even though I don't "really understand" most of the maths and physics behind it! Big thanks for all the work you put into this!
I found this guys videos one day ago, and His explanations are unbelievable. I graduated high school with a 2.6 gpa but this guy makes this stuff so easy to understand......good job man.......good job
Skywalker Shadai why do modern astronomists do everything in their power to come up with propulsion theories that MUST KISS EINSTEINS ASS OF HIS RELATIVITY THEORY? Everything must get heavier at relativistic speeds. Time must slow down for the person moving fast When you come up with insane ideas Like "stealing energy from a not just one but TWO FUKING ROTATING BLACK HOLES WHICH WE HAVE NEVER EVER OBSERVED EXCEPT BY LIGO WHICH THE SUPPOSED RESULTS FROM THE G WAVES WERE SO UNBELIEVABLY MINUTE THAT TO SAY IT WASN'T JUST COMPUTER OR DIGITAL NOISE IS ABSOLUTELY INSANE" EVEN IF IT WAS POSSIBLE WHERE WILL YOU FIND TWO BLACK HOLES? HOW THE FUK WOULD YOU REACH IT? YOU STEAL THE ENERGY HOW WILL YOU USE IT TO PROPEL YOURSELF? WHY DO ASTRONOMERS ALWAYS ALWAYS FORGET WE GOTTA SLOW THE CRAFT DOWN? 1000 years ago people didn't know what radio was or that light was just a SMALL PART OF THE EM SPECTRUM. If intelligent civilizations exist which they do, we would NOT HEAR THEIR RADIO SIGNALS. WHY? BECAUSE THE GALAXY IS MASSIVE. THERE ARE BILLIKNS OF GALAXIES. EVEN A RADIO SIGNAL FROM 500 LIGHT YEARS AWAY WOULD BE SO UNBELIEVABLE SMALL THAT IT WOULD REGISTER AS NOTHING OR STATIC. Humans since the dawn of civilization such as the Greeks for example up until the Renaissance, have had this incredible tendency to believe in a scientific theory for years. Decades, centuries. Or even MILLENIA. Surely aliens would be less LIMITED LIKE HUMANS BY OUR HUMAN BIASES AND BELIEF THAT EM WAVES AND SPEED OF EM WAVES ARE THE FASTEST SPEED IN THE UNIVERSE. THEY WOULD INSTANTLY RECOGNIZE THE FUTILITY OF USING RADIO OR EM WAVES AS A FORM OF COMMUNICATION. DON'T EVEN GET ME STARTED ON ALIENS USING ROCKETS TO GO ANYWHERE OTHER THAN MAYBE PUSHING A FEW SATELLITES UP INTO SPACE AND EVEN THEN THEY PROBABLY HAVE ANTI GRAVITY TECHNOLOGY. ALIENS MOST LIKELY DONT COMMUNICATE USING EM WAVES NOT TRAVEL IN SPEEDS USING MASS. THEY MOST LIKELY ARE ABLE TO CREATE STAR GATES, OR USE STARS AS WORMHOLES TO COMMUNICATE TO OTHER STARS, OR USE ANTI GRAVITY PROPULSION TO GO LIGHT YEARS PER DAY OR PER MONTH AT WORST CASE SCENARIO AND COMMUNICATE AT HUNDREDS OR THOUSANDS OF LIGHT YEARS PER HOUR. YOU SERIOUSLY THINK ALIENS POOR POOR ALIENS ARE LIKE HUMANS? WE JUST BARELY BEGAN UNDERSTANDING ANYTHING ABOUT TRAVEL TO SPACE IN THE LAST CENTURY. ALIENS WITH THOUSANDS OF YEARS AHEAD OF US CAN PROBABLY GO FROM STAR TO STAR WITHIN A FEW HOURS AND MAYBE TRAVEL THE LENGTH OF THE GALAXY IN A MATTER OF DAYS. WHO ARE WE TO IMPOSE OUR LIMITS ON ALIENS BASED ON OUR CURRENT LIMITED BELIEFS OF THE UNIVERSE JUST LIKE THE ANCIENT GREEKS IMPOSED THE IDEA THAT HEAVIER ROCKS FALL FASTER THAN LIGHTER ROCKS WHICH PEOPLE JUST BELIEVED AND WORSHIPPED THE IDEA WITH NO ONE HAVING TESTED IT
I love this. My education ended up going the way of mathematics (crippling fear of real world applications) but astronomy has a special place in my heart

Some thoughts/questions on caroming down the Halo Drive highway to pick up speed. 1. Can they be concatenated? If when approaching the deceleration blackhole (BH) could our intrepid voyagers chose to rather partially gravitationally sling shot AND add a further halo acceleration on their way out as they approach escape velocity, perhaps accelerating a further .2C to a maximum of .4C? I remember that they can't add acceleration as they depart the BH due to red shifting. But what about a tangental approach? Would an acute angle of added acceleration work out to be a further increase of speed on some (anticipated) intermediate vector? Or could they perhaps leverage a frame dragging blue shifting of their laser? I picture our halo-nauts (say 100 or so) encased in a solid carbon or similar process, as Han Solo in Star Wars, suspended and relatively impervious to moderate G-Forces under taking a ~75,000 year voyage of exploration/colonization out to perhaps 50 or 100 light years, using the method in my second question (50,000 years) get to, accelerate and then to decelerate to say .1C and then another 20,000 to coast to a near habitable system and a few thousand years of reverse slingshotting to park in that target system. 2. Could there be an angle of boomerang such that some additional acceleration could be realized as the ship left after a tangental encounter? I'm visualizing a beam entry such that the light would go say 195 degrees around the frame dragging BH and intercept the ship when it was a few light minutes on its way. 3. If so, would the following scenario work for even greater accelerations. Could our intrepid ship enter in to a very deep figure-eight orbit around both members of a binary BH system such that the ship could accelerate from one to the other and from that back to the other and so on until an escape velocity from the very close figure eight orbit of say .5, .6, or even .8C could be reached. I wouldn't think that any organic material would survive such accelerations-but for robotic probes or cargo it might be possible to withstand hundreds or even a few thousand Gs and would may be take only a few seconds or minutes from orbital insertion to then be flung out towards their next destination at very high relativistic speeds. 4. Shielding at relativistic speeds: Taking a page from the Russian VA-111 Shkval torpedo, would not a stream of ionized neon atoms (a low powered ion drive) fired out of the nose of our .6C probe have sufficient inherited kinetic mass to obliterate any interstellar dust particles before they reached the hull of the ship without significantly slowing the ship? Yes there would be a lot of radiation created by kinetic shield but first, most of it would be tangental and not actually reach the ship and two, as you said before, such ships would have lots of shielding built into the design. I really love this channel. It gets me thinking on a grand scale.
3. If we are assuming a relatively near by solar system you are approaching from could you use the halo drive in combo with a local star based gravity assist to create a perfect moment of momentum transfer from a sun and a halo drive?
Just found your channel and I can't get enough. We need more people thinking and talking about the concepts you are exploring. To think outside of the box that is this planet is so invigorating! Keep up the amazing work!
I’ve been watching this guy for a good minute now and just discovered he is far more than just a pretty face and entrancing voice; this guy is an actual professor at Columbia University and studied at Cambridge, got a Ph.D. in Astrophysics tan University College London with postdoc work at Harvard University before joining Columbia University in 2015. All this work gave him ample fee time to author more than 90 scientific publications and envision the Halo Drive. -Holy Hell, What have I done with my life; -what have you done with yours?
You stated that the estimated average distance between black holes = 12 parsecs = 12 * 3.26 light-years = 39.12 light-years. Even launching from an optimal place in our solar system (not Earth), we would still need to travel at sub-relativistic speed for a very long time before reaching a "relativistic fueling station". Anyways, we will have a lot to explore in our own solar system for 1000s of years to come, keeping us quite busy and giving us time to learn a lot more Science.
Richard Elkins This is true. But a black hole could come closer to us at some point in the future. But I still think it's important to check to see if other civilizations might have arisen closer to their own local fuelling station. They could already be on the move
Yeah. That was the first thing I did when I heard "12 parsecs". I went to my Google search for a calculator. We can explore the galaxy with telescopes. I was going to add "sending probes" through the black hole network. But at those distances, getting a signal back will take forever. As for humans in space, what we really care about are earth like habitats, where ever they maybe in the galaxy. For the amount of energy required, and time to get to get to a BH station, it would be far simpler to build our own habitats in space, around the solar system. It would require a level of AI and automation, that could mine asteroids, do outer space manufacturing, build megastructures. It would not be far out physics. It's in line with the trends for the next couple of centuries (automation). What I am not taking into account here, is a transhuman future. Here humans merge with AI, or humans upload themselves into AI, have essentially unlimited lifetimes, can put themselves to "sleep", till they arrive. Centuries would not matter. Here the BH network may have some meaning. But it would be a very different type of civilization, even existence.
@@Grassyknolldallas How is he wrong? A parsec is about 3.3 light years. So yes, it would take an absurd amount of time to get to the nearest black holes at sub-relativistic speeds.
Average just means average. It does not mean "the same distance everywhere". There are more stars at the core of the galaxy, and less here where we are. Don't expect a "central station" in your area.
I honestly think you’re breaking academic ground here in a way that many others will replicate in the future. Your channel gives you the opportunity to attract public interest for your research work. I’ve seen public outreach work punished so much generally, but yours is so much around your own published research so it’s unarguable to your peers that you’re putting in the expected effort to do research and get published. And you present it in an engaging way that I know that many conventional academics would struggle with. I look forward to see where this channel goes and what academia is like in another 10 or 15 years. Not every field will translate as well to RUclips videos as cosmology and astrophysics, but I can imagine steps in this direction at least.
An astute observation that seems to ring true as he was able to secure the necessary time on JWST to make a ground or space breaking discovery today in 2025.
I think that if you haven't been inspired by this, you haven't really understood it. Good job helping people do that. One question for now is whether we can expect Kerr BHs to give us enough push?
Excellent question. The mathematics behind the Doppler shift of a bomberanged Kerr geodesic are nontrivial and something I discussed in private with Claes Cramer. Sadly Craes left physics but he does a) agree a blue shift will occur b) think it’s possible to solve for said shift. Work in progress.
I've never heard of this idea before and at the start of this video I thought it was some kind of joke. But by the time the fact that we are expecting to find 100m black holes across the Milky Way came up (another thing I didn't know), many of which can be expected to be located just round the corner so-to-speak, I was like OMG! I did reflect that marketing this service and actually selling tickets to those of a nervous disposition might be a little....challenging. Incredible video, incredible channel.
You are simply amazing. I love how there are slowly more and more scientific channels on RUclips sharing their insight in truly scientific and educational way and not just in a way to get a lot of likes. I truly hope your channel grows in popularity. Your way of thinking is how everybody should think and your closing sentence really nails it. Dreams are what brought us to the moon and back and dreams will be what helps us solve our current ecological problems and one day will bring us to the stars. Looking forward to your future videos

hello david. you could be the new brian cox. you have a gift, like he does, to convey difficult concepts easily, but also you have the ability to think very coherently.
I just love listening to David not knocking anybody else on the channel but David is in my opinion one of the best informative youtubers there is. I''m just a normie that is facinated by this stuff
"one of a few dozen people living there at the time" *weeps indigenously* ...I'm just giving you a hard time. You have some amazing content! Thank you for making your channel.
My main problem with this concept is that even if you can overcome all the technical and engineering issues to achieve 0.2 c it's still not fast enough. 1.0 c isn't fast enough. We need something that can go 1000 c or we're just not getting out where the fun stuff is.
I like how he describes something that is, currently, pure fantasy (traveling 10-20% the speed of light) as "extremely challenging." We won't travel that fast (if ever) for hundreds or even thousands of years.
@@gamingcreatesworlddd2425 you're not wrong. But, there's a scale issue. Nothing, and I mean absolutely nothing humans have achieved in all of history (recorded or otherwise) comes remotely close to achieving the speed of light. There is literally nothing that compares as an analogue, a metaphor, etc. It is literally in the realm of fantasy, at least right now, of superman flying unassisted through the air.
Thanks once again for a thorough - and thoroughly enjoyable - video! For those of us who follow astrophysical topics including the future of space travel, it's become something of a tired joke to point out to the non-nerds that a spaceship doesn't have to look sleek & aerodynamic. However, in the case of relativistic speeds, it may indeed be a factor. A long, sharp, cone on the leading end of the ship (assuming it HAS a leading end!) might be quite useful. Many things about space travel in general strike me as calling for multiple approaches, even on the same ship (such as multiple propulsion methods: vital!) In this case, a good solid piece of metal or ceramic (or whatever material scientists can dream up), possibly with a rapidly flipping electrical charge, might make a good start. Maybes include: cold or hot plasma, aerogel, PTFE, & even a retractable laser cannon battery for targetable objects (guided & fired by computer), and, of course, as many of the above as don't actively interfere with each other. I'm sure other things can be thought up as well; the more the merrier. It seems to me that minimizing perpendicular surface area is key, as opposed to treating the idea like ablation shielding at 97% light speed! I agree with you fully that it's great fun - AND useful - to consider the possibilities of the future of a space-faring humanity! Rikki Tikki.
I just wanted to comment on your last statement. You couldn't be more correct about folks needing to take a minute to ask big questions and look for answers to them. Thank you for doing your research and making these videos. It has helped me in many ways with big questions I have. Cheers to you and have a great day! 👽🌬💨💨💨🛸
So far, you and PBS Space Time are my favorite physics channels!! Perfect way to spend time winding down at the end of the day while learning about the beauty of our universe! Thank you for all you do!
I love these complex videos that really make those of us with Scientific minds to really deeply think about how these processes could be imagined. I love the entire series tonnes. My 2021 resolution is to become one of your super contributors and a Patrionne
One deal breaker for relativistic travel I think would be the fact that although time dilation might make the journey shorter for you, by the time you get home everyone you know and love will be a remnant of a long forgotten era.
You and Brian Cox have a very very similar voice! but your intelligence and delivery of that intelligence or intel or data into digestible forms for many of varying intelligence to understand is something of beauty (I know for you it's probably easy to understand but other people reading put in plain English) david kipping has a beautiful brain and your teaching skills are eloquent... the delivery feels fluid and we are but sponges soaking up the information you pour out!
I love your work don't give up. This is my top five of your videos. You incredibly intelligent, however you relay your work into a easy pick up for newcomers!. Great job we need more people like you in humanity.
This dude looks like someone thought to themselves what the coolest person they could make is and we got this guy. Black leather jacket, british accent, awesome hair, and extremely smart.
I liked your idea to look to look for evidence of extraterrestrial life, or industrial activity, around these waypoints. It'd also be practical evidence for your work. You'd be the first scientist whose theories were tested by an alien species :)
E.M. H Imagine we finally develop a halo drive and journey to a black hole only to find out another civilization is currently jealously guarding it because they don't want anyone else using their highway system.
Build a ring that uses a stationary halo drive on the opposite side of the system or rotates to use the system in various directions to balance out the system till the moment of release. This would allow for the ring to contain lenses. Containing the entire system creates a modular model for all the stops in the system. I am working on the food systems :) Love this work!
The trick is to create a “sail” that can capture dark energy. Then, constant acceleration may be possible (such as convenient 1g). Even so, such a drive would only be effective for humans in the solar system, not interstellar. Concepts discussed by author Samuel Rose of the Scout Report Universe.
David, you are the MAN! This is the most exciting future propulsion work since 1994 Alcubier(sorry for spelling) and yet with your concept we already know that it will work! got any ideas on ionizing combustion products and magnetic nozzles?(just kidding don't want to distract you)
Thanks! This past year I had three big ideas I wanted to publish and this is the first of them. The second is in review right now so stay tuned and the third I’m working on.
@@CoolWorldsLab Very exciting, I look forward to it. If you would be so kind as to provide a hint on the category of the research I would be very grateful. Is it related to exoplanet research or another excursion into similar but unrelated (atleast directly) fields? I'm interested in getting some insight into where your inspirations stem from so that I might lend my brain capacity towards generating ideas that contrubute to the future of our civilization. Lately I've been occupied with figuring out how to extract anitmatter from thunderstorms, like those that happen in a particular bay in Venezuela, instead of trying to make it ourselves which is a nonstarter in my opinion. Its interesting that the ISS detects persistant anomalies near thunderstoms that have the appearance of flying vehicles, I can only assume that I'm not the first to have such an Idea, and one can imagine a group researching this would keep their progress secret. Sorry for the conspiracy theory tangent ;)
This channel is the best this guys information has been peer reviewed by students at universities and delivered to us with his channel what a great channel
Absolutely love your videos. Absolutely fascinating. Please write a book with all of these fascinating concepts including the mathematics involved explained for all of us space / spacecraft / astrophysics / geeks such as myself. Thank you so much for your video productions.
Thank you for a great channel! Do we know if primordial black holes also rotate? I'm asking because of the recent speculation that "Planet Nine" could be a primordial black hole.
I've only recently found this channel and been binge-watching, very good! The Halo drive is certainly and interesting concept... I have some concerns with regard to it's practicality as while the travel across the continental USA analogy is a good one it doesn't take account of lifespan vs distance to your nearest 'station'. Still, It's a reasonable rule of thumb that if a person can imagine something and it doesn't violate physics them somebody will do it eventually. Thoughts: -If there really are no show-stoppers this really does magnify the Fermi paradox. -On the subject of using the Halo drive as an energy source rather than for propulsion I presume the analogy of a water wheel might fit: Shine your laser around the black hole but arrange to receive the return light at a tangent to spin up your ship rather than push it along. That rotational energy could then presumably be used to do useful work... a good deal may be needed to stabilize your power plant but as it's essentially free that's not a practicable issue.
wow! Great presentation and an even greater idea. This idea beats anything I have heard yet on solving the interstellar flight problem. I hope you can get some traction with it amongst the scientific community. Its as deserving an idea as any, to be developed further.
could you redirect the push into rotation so that a station in orbit can harness the energy using the halo technique? You could use the excess energy to rotate two or more flywheels like water wheels and the spinning in opposition would also add stability. the rest of the energy would have to be balanced against the gravitational attraction and maybe the orbital motion like a sailboat tacking. My other idea is using a lattice of lasers creating artificial hill sphere resonant nodes. Mmm yeah that's elaborate. = D
I had the same thought... you could use the beam energy to rotate massive fly wheel rings that orbit the black hole. Then you could pull the kinetic energy off of the orbiting wheels as needed.
Alright. So the Mass Relays network can be real, just add black holes instead! Also I'm just so amazed by this concept, or generally by this channel. It's like... It's like what we think of Leonardo DaVinci and his inventions he couldn't create because of lack of good materials, but for our future!
All the problems we humans have/cause on earth are kind of pathetic after watching videos like this. In the sense that we should be dreaming big and try to accomplish stuff as the human race instead of fighting each other.
Hmmm, thinking big. So a globular cluster like Messier 22 for example with its black holes that happily coexist in close (relatively speaking) proximity could become a real jump off point to the rest of the galaxy given how nearby it is. Practically right next door. I'm thinking a coffee shop and a walmart.
I wonder what would happen if you threw a 2*10^43 Hz laser at a spinning black hole? could it be blueshifted further? can light have a wavelength smaller than planck constant? uuuuh brain hurts....
Is that Planck frequency? That would be an interesting experiment. Sadly we have no idea how quantum and GR can be fused really, making this unpredictable
What if, just what if...suddenly our history books changed saying "mysterious laser beam hit Pentagon dating 1800's" the black hole is actually is TIME WARP or a TIME TRAVELLING portal.. hehe
ImagIne for a moment that we are one of the "first" in our galaxy, if we can map and use these black hole highways, and leave maps of the ones we've discovered, thousands/millions of years from then there might be races who discover those highways and wonder at who the race was in the distant past that discovered them. WE could be considered one of the "Firstcomers", one of the precursor races that paved the way for others to follow. Kind of a cool legacy to leave long after we've gone, or advanced to beyond the meat bags we are now. Thanks Dr. Kipping, yet another video that makes me think, wonder, and ponder the future.
I honestly cant comprehend how light(something without weight or mass) could stop a ship weighing tons, moving at relativistic speeds 🤷🏼♂️ i think i need to go watch the breakthrough starshot videos on how they explain this concept. I dont understand how light could move an object
Don't take my word on any of this, it's just how my uneducated brain makes sense of it. Light has energy, even without mass. If light is 'absorbed' by something, it's energy can't just disappear, so it's converted into another form, of which i guess one possibility is heat. Heat is essentially a form of kinetic energy, the 'vibration' of atoms. In the reverse way, hot objects emit light again, cooling them down in the process. I have no clue what the loss factors are in the process of the creation of light in any of the ways we know of, or the conversion from light into storable energy of some sort.
@@JoshuaOhl it seems like e=mc2 is just oversimplified. A part of the energy apparently stems from 'momentum' which photons should have despite their lack of mass, but i can't wrap my head around the definition of 'momentum' of massless particles. from what i read, the formula should actually be "e^2 = (mc^2)^2 + (pc)^2", where p is the momentum.
There is so much I could say about this page and community. But I will just say thank you for such amazing content and amazing community. I have found my people.
Hi, this was good, although the short movie clip you showed said "you want to go in to the Black hole?" - "In, Through, Beyond" (and it is here where my argument takes place, the use of the word "beyond" isn't a vector in space time, expand....
What about counter rotating binary black holes? Do they exist? Could you position spacecraft between them and create energy? I would assume that they cancel each other out if they are too close.
To stabilise the spacecraft, couldn't you just force it into a constant freefall into the black hole, that you counterbalance with the Halo Drive? Using something like an anchor on a long string that is much closer to the black hole.
Damn I think you got it! Yes I don’t know why I didn’t think of this because I have a related paper in draft on a similar idea for the Sun. The outward force of the halo subtracts partially off the inward freefall acceleration which essentially hacks Keplers Third Law making the black hole appear lower mass. See arxiv.org/abs/0901.1606
Uhh, did I win something? :D I was hoping the same thing would work for a space elevator. having an electromagnet that gets pushed outwards by earths magnetic field and thereby stabilising the elevator. But I guess that is a bit more complicated.

History being made in the RUclips comments. What an absolute bonkers age do we live in?
This channel is incredible. I recently found this community and I love it. Such a peaceful vibe, I listen at night before bed to help me relax and have an existential crisis lol
Thanks for joining us Dustin
Same. It's 5am here
Same here. Its so fascinating and also so relaxing to relax to while unwinding for bed.
When Dr. Kipping appears on Event Horizon, it's an event @ my house.
I agree the voice puts one to sleep, but I am at a loss how to 'relax and have an existential crisis' fcol
If you were my teacher in high school, I wouldn't be an unemployed plumber. I hope your students realize how good you are at what you do.
It's not your teachers fault, that you are a loser.
Gosh, I LOVE watching your videos, because you are a Scientist who is not embarassed to speculate imaginatively about the cosmos and interstellar travel, and yet you always do so by “sticking to the rules”, and imagining realistic possibilities!
After watching several episodes I feel so smart due to the fact that your explanations are incredibly focused and understandable. Thank you
Found your channel a few weeks back... And I'm watching several episodes a day... And is a fantastic balance of astronomy/physics/math /theoretical science...
Highly underrated channel too...
Great work @cool Worlds.
And philosophy..
This is the most plausible almost light speed method I’ve ever heard of, why am I only hearing of it now?? Love your videos man!
I'm wondering if microblack holes can work
Because ,as so technically and scientifically interesting it is this concept, and someone probably could use or create ideas from this to something different,it fails in practicallity.
The closest black hole is at 1560 light years. And,to make you an idea,all Star Trek empires, are in a cluster not longer than 1600 light years in diameter..
Most Dune saga,with thousands of worlds involved, having to fold space in order to function, occurs at tens of ligths years of our solar systen,and between each of them.
The closest star to to ours is 'just' 4,2 light years away
So...using his system would be like...walking thousands of miles from your city,in order to take a jet ...to go and see your grandma...instead of walking to her house,just a few miles ,in the same city you live in.
By the time It wouldn't be impractical to have to travel to the nearest black hole to use It,that would be just ,maybe, a "cheaper way" to go even far,far away
@mryellow6918 this is my guess from a basic look on Wikipedia so don't take me to seriously. I'm just a stoner from Canada.
Micro black holes disappear almost instantly and being micro, the large size of the laser would only lose most of its energy, since only a microscopic amount of space time is being curved, losing most of the laser into deep space.
@@aqistoyyowhen Voyager got its ass flung to the Delta quadrant wasn't that 70,000 light years? And there was an Empire there, the Borg lol.
just found this channel, as many others probably have. definitely not a science student, not by any sense of the word; but the clarity and enthusiasm you bring to the topics you do is immensely elucidating, regardless of the subject.
bonus is that as you're a professor that produces and interacts with actual validated research papers, citation and credibility of knowledge is much less of a potential issue. subscribed, interested to see what content comes in the future :)
Thanks for tuning in! Yes sadly being a professor means I can’t churn out videos every week but we have a bunch of great videos planned over the next few months!
Newbie here, as well. Amazing information here. Subscribed after watching 1 of his videos. Great comments, too. No hateful arguments. Nice place to be.
@@CoolWorldsLab why is it sad being a professor?
Yes, I agree. It's all very well watching an interesting theory video BUT without having the least idea about the producer/s of said video, you've no idea if it's just some nutjob in basement bedroom wanting attention or someone who actually has a clue which is the case here. Like you, I'm not a science student in any sense of the word either.
@@CoolWorldsLab Better a few well thought out ones than a load of half a- - -d ones.
I love seeing the inclusion of images and clips from some of my favorite games, those being Stellaris and SpaceEngine! A lot of my own ideas regarding interstellar travel stemmed from game mechanics.
I don't have any physics related education what so ever but man do I love watching these videos! Very very interesting stuff even though I don't "really understand" most of the maths and physics behind it! Big thanks for all the work you put into this!
Yes same for me really love this cannel to interesting stuff

Skywalker Shadai why do modern astronomists do everything in their power to come up with propulsion theories that MUST KISS EINSTEINS ASS OF HIS RELATIVITY THEORY? Everything must get heavier at relativistic speeds. Time must slow down for the person moving fast
When you come up with insane ideas Like "stealing energy from a not just one but TWO FUKING ROTATING BLACK HOLES WHICH WE HAVE NEVER EVER OBSERVED EXCEPT BY LIGO WHICH THE SUPPOSED RESULTS FROM THE G WAVES WERE SO UNBELIEVABLY MINUTE THAT TO SAY IT WASN'T JUST COMPUTER OR DIGITAL NOISE IS ABSOLUTELY INSANE"
EVEN IF IT WAS POSSIBLE WHERE WILL YOU FIND TWO BLACK HOLES? HOW THE FUK WOULD YOU REACH IT? YOU STEAL THE ENERGY HOW WILL YOU USE IT TO PROPEL YOURSELF? WHY DO ASTRONOMERS ALWAYS ALWAYS FORGET WE GOTTA SLOW THE CRAFT DOWN?
1000 years ago people didn't know what radio was or that light was just a SMALL PART OF THE EM SPECTRUM.
If intelligent civilizations exist which they do, we would NOT HEAR THEIR RADIO SIGNALS. WHY? BECAUSE THE GALAXY IS MASSIVE. THERE ARE BILLIKNS OF GALAXIES. EVEN A RADIO SIGNAL FROM 500 LIGHT YEARS AWAY WOULD BE SO UNBELIEVABLE SMALL THAT IT WOULD REGISTER AS NOTHING OR STATIC. Humans since the dawn of civilization such as the Greeks for example up until the Renaissance, have had this incredible tendency to believe in a scientific theory for years. Decades, centuries. Or even MILLENIA. Surely aliens would be less LIMITED LIKE HUMANS BY OUR HUMAN BIASES AND BELIEF THAT EM WAVES AND SPEED OF EM WAVES ARE THE FASTEST SPEED IN THE UNIVERSE. THEY WOULD INSTANTLY RECOGNIZE THE FUTILITY OF USING RADIO OR EM WAVES AS A FORM OF COMMUNICATION. DON'T EVEN GET ME STARTED ON ALIENS USING ROCKETS TO GO ANYWHERE OTHER THAN MAYBE PUSHING A FEW SATELLITES UP INTO SPACE AND EVEN THEN THEY PROBABLY HAVE ANTI GRAVITY TECHNOLOGY.
ALIENS MOST LIKELY DONT COMMUNICATE USING EM WAVES NOT TRAVEL IN SPEEDS USING MASS. THEY MOST LIKELY ARE ABLE TO CREATE STAR GATES, OR USE STARS AS WORMHOLES TO COMMUNICATE TO OTHER STARS, OR USE ANTI GRAVITY PROPULSION TO GO LIGHT YEARS PER DAY OR PER MONTH AT WORST CASE SCENARIO AND COMMUNICATE AT HUNDREDS OR THOUSANDS OF LIGHT YEARS PER HOUR. YOU SERIOUSLY THINK ALIENS POOR POOR ALIENS ARE LIKE HUMANS? WE JUST BARELY BEGAN UNDERSTANDING ANYTHING ABOUT TRAVEL TO SPACE IN THE LAST CENTURY. ALIENS WITH THOUSANDS OF YEARS AHEAD OF US CAN PROBABLY GO FROM STAR TO STAR WITHIN A FEW HOURS AND MAYBE TRAVEL THE LENGTH OF THE GALAXY IN A MATTER OF DAYS. WHO ARE WE TO IMPOSE OUR LIMITS ON ALIENS BASED ON OUR CURRENT LIMITED BELIEFS OF THE UNIVERSE JUST LIKE THE ANCIENT GREEKS IMPOSED THE IDEA THAT HEAVIER ROCKS FALL FASTER THAN LIGHTER ROCKS WHICH PEOPLE JUST BELIEVED AND WORSHIPPED THE IDEA WITH NO ONE HAVING TESTED IT

Some thoughts/questions on caroming down the Halo Drive highway to pick up speed.
1. Can they be concatenated? If when approaching the deceleration blackhole (BH) could our intrepid voyagers chose to rather partially gravitationally sling shot AND add a further halo acceleration on their way out as they approach escape velocity, perhaps accelerating a further .2C to a maximum of .4C? I remember that they can't add acceleration as they depart the BH due to red shifting. But what about a tangental approach? Would an acute angle of added acceleration work out to be a further increase of speed on some (anticipated) intermediate vector? Or could they perhaps leverage a frame dragging blue shifting of their laser? I picture our halo-nauts (say 100 or so) encased in a solid carbon or similar process, as Han Solo in Star Wars, suspended and relatively impervious to moderate G-Forces under taking a ~75,000 year voyage of exploration/colonization out to perhaps 50 or 100 light years, using the method in my second question (50,000 years) get to, accelerate and then to decelerate to say .1C and then another 20,000 to coast to a near habitable system and a few thousand years of reverse slingshotting to park in that target system.
2. Could there be an angle of boomerang such that some additional acceleration could be realized as the ship left after a tangental encounter? I'm visualizing a beam entry such that the light would go say 195 degrees around the frame dragging BH and intercept the ship when it was a few light minutes on its way.
3. If so, would the following scenario work for even greater accelerations. Could our intrepid ship enter in to a very deep figure-eight orbit around both members of a binary BH system such that the ship could accelerate from one to the other and from that back to the other and so on until an escape velocity from the very close figure eight orbit of say .5, .6, or even .8C could be reached. I wouldn't think that any organic material would survive such accelerations-but for robotic probes or cargo it might be possible to withstand hundreds or even a few thousand Gs and would may be take only a few seconds or minutes from orbital insertion to then be flung out towards their next destination at very high relativistic speeds.
4. Shielding at relativistic speeds: Taking a page from the Russian VA-111 Shkval torpedo, would not a stream of ionized neon atoms (a low powered ion drive) fired out of the nose of our .6C probe have sufficient inherited kinetic mass to obliterate any interstellar dust particles before they reached the hull of the ship without significantly slowing the ship? Yes there would be a lot of radiation created by kinetic shield but first, most of it would be tangental and not actually reach the ship and two, as you said before, such ships would have lots of shielding built into the design.
I really love this channel. It gets me thinking on a grand scale.
3.
If we are assuming a relatively near by solar system you are approaching from could you use the halo drive in combo with a local star based gravity assist to create a perfect moment of momentum transfer from a sun and a halo drive?
Finally, a RUclips channel with an actual scientist at the cutting edge of astrophysics. Very refreshing. This channel is gonna go places.
Just found your channel and I can't get enough. We need more people thinking and talking about the concepts you are exploring. To think outside of the box that is this planet is so invigorating! Keep up the amazing work!
I’m being taught by an actual genius, never stop making these videos please.
My god this channel is so underrated. Your vids and your work are awesome

All this work gave him ample fee time to author more than 90 scientific publications and envision the Halo Drive.

You stated that the estimated average distance between black holes = 12 parsecs = 12 * 3.26 light-years = 39.12 light-years. Even launching from an optimal place in our solar system (not Earth), we would still need to travel at sub-relativistic speed for a very long time before reaching a "relativistic fueling station". Anyways, we will have a lot to explore in our own solar system for 1000s of years to come, keeping us quite busy and giving us time to learn a lot more Science.
Richard Elkins
This is true. But a black hole could come closer to us at some point in the future. But I still think it's important to check to see if other civilizations might have arisen closer to their own local fuelling station. They could already be on the move
Yeah. That was the first thing I did when I heard "12 parsecs". I went to my Google search for a calculator. We can explore the galaxy with telescopes. I was going to add "sending probes" through the black hole network. But at those distances, getting a signal back will take forever.
As for humans in space, what we really care about are earth like habitats, where ever they maybe in the galaxy. For the amount of energy required, and time to get to get to a BH station, it would be far simpler to build our own habitats in space, around the solar system. It would require a level of AI and automation, that could mine asteroids, do outer space manufacturing, build megastructures. It would not be far out physics. It's in line with the trends for the next couple of centuries (automation).
What I am not taking into account here, is a transhuman future. Here humans merge with AI, or humans upload themselves into AI, have essentially unlimited lifetimes, can put themselves to "sleep", till they arrive. Centuries would not matter. Here the BH network may have some meaning. But it would be a very different type of civilization, even existence.
Richard Elkins your calculations are wrong, thanks for trying
@@Grassyknolldallas How is he wrong? A parsec is about 3.3 light years. So yes, it would take an absurd amount of time to get to the nearest black holes at sub-relativistic speeds.
Average just means average.
It does not mean "the same distance everywhere".
There are more stars at the core of the galaxy, and less here where we are.
Don't expect a "central station" in your area.
This is probably one of the best channels I've found in a long time.
I'm an econ major but damn this stuff is tempting me to get at least a minor in physics
I honestly think you’re breaking academic ground here in a way that many others will replicate in the future. Your channel gives you the opportunity to attract public interest for your research work. I’ve seen public outreach work punished so much generally, but yours is so much around your own published research so it’s unarguable to your peers that you’re putting in the expected effort to do research and get published. And you present it in an engaging way that I know that many conventional academics would struggle with.
I look forward to see where this channel goes and what academia is like in another 10 or 15 years. Not every field will translate as well to RUclips videos as cosmology and astrophysics, but I can imagine steps in this direction at least.
An astute observation that seems to ring true as he was able to secure the necessary time on JWST to make a ground or space breaking discovery today in 2025.
I think that if you haven't been inspired by this, you haven't really understood it. Good job helping people do that. One question for now is whether we can expect Kerr BHs to give us enough push?
Excellent question. The mathematics behind the Doppler shift of a bomberanged Kerr geodesic are nontrivial and something I discussed in private with Claes Cramer. Sadly Craes left physics but he does a) agree a blue shift will occur b) think it’s possible to solve for said shift. Work in progress.
I've never heard of this idea before and at the start of this video I thought it was some kind of joke. But by the time the fact that we are expecting to find 100m black holes across the Milky Way came up (another thing I didn't know), many of which can be expected to be located just round the corner so-to-speak, I was like OMG! I did reflect that marketing this service and actually selling tickets to those of a nervous disposition might be a little....challenging. Incredible video, incredible channel.
You are simply amazing.
I love how there are slowly more and more scientific channels on RUclips sharing their insight in truly scientific and educational way and not just in a way to get a lot of likes. I truly hope your channel grows in popularity. Your way of thinking is how everybody should think and your closing sentence really nails it.
Dreams are what brought us to the moon and back and dreams will be what helps us solve our current ecological problems and one day will bring us to the stars.
Looking forward to your future videos

"one of a few dozen people living there at the time" *weeps indigenously* ...I'm just giving you a hard time. You have some amazing content! Thank you for making your channel.
My main problem with this concept is that even if you can overcome all the technical and engineering issues to achieve 0.2 c it's still not fast enough.
1.0 c isn't fast enough. We need something that can go 1000 c or we're just not getting out where the fun stuff is.
Depends, are you on the ride or not.
The spice melange should improve matters
I like how he describes something that is, currently, pure fantasy (traveling 10-20% the speed of light) as "extremely challenging." We won't travel that fast (if ever) for hundreds or even thousands of years.
Still innovation only comes if we break our barriers he only talked about 10 to 20% not that oh we can travel faster than light
@@gamingcreatesworlddd2425 you're not wrong. But, there's a scale issue. Nothing, and I mean absolutely nothing humans have achieved in all of history (recorded or otherwise) comes remotely close to achieving the speed of light. There is literally nothing that compares as an analogue, a metaphor, etc. It is literally in the realm of fantasy, at least right now, of superman flying unassisted through the air.
Thanks once again for a thorough - and thoroughly enjoyable - video! For those of us who follow astrophysical topics including the future of space travel, it's become something of a tired joke to point out to the non-nerds that a spaceship doesn't have to look sleek & aerodynamic. However, in the case of relativistic speeds, it may indeed be a factor. A long, sharp, cone on the leading end of the ship (assuming it HAS a leading end!) might be quite useful. Many things about space travel in general strike me as calling for multiple approaches, even on the same ship (such as multiple propulsion methods: vital!) In this case, a good solid piece of metal or ceramic (or whatever material scientists can dream up), possibly with a rapidly flipping electrical charge, might make a good start. Maybes include: cold or hot plasma, aerogel, PTFE, & even a retractable laser cannon battery for targetable objects (guided & fired by computer), and, of course, as many of the above as don't actively interfere with each other. I'm sure other things can be thought up as well; the more the merrier. It seems to me that minimizing perpendicular surface area is key, as opposed to treating the idea like ablation shielding at 97% light speed! I agree with you fully that it's great fun - AND useful - to consider the possibilities of the future of a space-faring humanity! Rikki Tikki.
Yes very true. The starshot sail plans to tip over on its side during the trip to minimize its portfolio for the same reason
I just wanted to comment on your last statement. You couldn't be more correct about folks needing to take a minute to ask big questions and look for answers to them.

Hey I'd also recommend the channel SEA, he does very similar videos.
I love these complex videos that really make those of us with Scientific minds to really deeply think about how these processes could be imagined. I love the entire series tonnes. My 2021 resolution is to become one of your super contributors and a Patrionne
One deal breaker for relativistic travel I think would be the fact that although time dilation might make the journey shorter for you, by the time you get home everyone you know and love will be a remnant of a long forgotten era.
The universe imposes a terrible cost
You and Brian Cox have a very very similar voice!
but your intelligence and delivery of that intelligence or intel or data into digestible forms for many of varying intelligence to understand is something of beauty (I know for you it's probably easy to understand but other people reading put in plain English) david kipping has a beautiful brain and your teaching skills are eloquent... the delivery feels fluid and we are but sponges soaking up the information you pour out!
Brian’s amazing so that’s a very kind complement and comparison!
Brian WANKER Cox, nah
This channel is a hidden gem on RUclips.
Nerdgasm! Theoretical work with good foundations is always so very interesting
I love your work don't give up. This is my top five of your videos. You incredibly intelligent, however you relay your work into a easy pick up for newcomers!. Great job we need more people like you in humanity.
This documentary it’s the best one so far
This dude looks like someone thought to themselves what the coolest person they could make is and we got this guy. Black leather jacket, british accent, awesome hair, and extremely smart.
Draws a lot from professor Brian Cox , his look and presenting style
I liked your idea to look to look for evidence of extraterrestrial life, or industrial activity, around these waypoints. It'd also be practical evidence for your work. You'd be the first scientist whose theories were tested by an alien species :)
E.M. H Imagine we finally develop a halo drive and journey to a black hole only to find out another civilization is currently jealously guarding it because they don't want anyone else using their highway system.
This is so nursing to my spirit in these turbulent times. To imagine the possibilities and dream of such things. You are so appreciated sir.
Such an amazing channel. Feels like I should be paying for this information.
Yeah, too valuable right !!!
Build a ring that uses a stationary halo drive on the opposite side of the system or rotates to use the system in various directions to balance out the system till the moment of release. This would allow for the ring to contain lenses. Containing the entire system creates a modular model for all the stops in the system. I am working on the food systems :) Love this work!

This channel is what you get when superman fights misinformation and educates the public instead of fighting crime
The trick is to create a “sail” that can capture dark energy. Then, constant acceleration may be possible (such as convenient 1g).
Even so, such a drive would only be effective for humans in the solar system, not interstellar.
Concepts discussed by author Samuel Rose of the Scout Report Universe.
Wow! I've never seen a video like this before!
This explains why you understand our universe so well, you are the one doing research on it!
At 9:26 - I hope you mean a "stationary" rather than "stationery" black hole. A stationery black hole would be made of paper, envelopes and pens.
What about a black hole made from paperclips? ruclips.net/video/3mk7NVFz_88/видео.html

Glad to be a contemporary of David Kipping and his group of enthusiastic students!!! Keep up the good work!
David, you are the MAN! This is the most exciting future propulsion work since 1994 Alcubier(sorry for spelling) and yet with your concept we already know that it will work! got any ideas on ionizing combustion products and magnetic nozzles?(just kidding don't want to distract you)
Thanks! This past year I had three big ideas I wanted to publish and this is the first of them. The second is in review right now so stay tuned and the third I’m working on.
@@CoolWorldsLab Very exciting, I look forward to it. If you would be so kind as to provide a hint on the category of the research I would be very grateful. Is it related to exoplanet research or another excursion into similar but unrelated (atleast directly) fields? I'm interested in getting some insight into where your inspirations stem from so that I might lend my brain capacity towards generating ideas that contrubute to the future of our civilization. Lately I've been occupied with figuring out how to extract anitmatter from thunderstorms, like those that happen in a particular bay in Venezuela, instead of trying to make it ourselves which is a nonstarter in my opinion. Its interesting that the ISS detects persistant anomalies near thunderstoms that have the appearance of flying vehicles, I can only assume that I'm not the first to have such an Idea, and one can imagine a group researching this would keep their progress secret. Sorry for the conspiracy theory tangent ;)
It would be interesting if Venezuela had significant energy resources besides oil, geopolitically speaking

Thank you for a great channel! Do we know if primordial black holes also rotate? I'm asking because of the recent speculation that "Planet Nine" could be a primordial black hole.
I've only recently found this channel and been binge-watching, very good!
The Halo drive is certainly and interesting concept... I have some concerns with regard to it's practicality as while the travel across the continental USA analogy is a good one it doesn't take account of lifespan vs distance to your nearest 'station'. Still, It's a reasonable rule of thumb that if a person can imagine something and it doesn't violate physics them somebody will do it eventually.
Thoughts:
-If there really are no show-stoppers this really does magnify the Fermi paradox.
-On the subject of using the Halo drive as an energy source rather than for propulsion I presume the analogy of a water wheel might fit: Shine your laser around the black hole but arrange to receive the return light at a tangent to spin up your ship rather than push it along. That rotational energy could then presumably be used to do useful work... a good deal may be needed to stabilize your power plant but as it's essentially free that's not a practicable issue.
wow! Great presentation and an even greater idea. This idea beats anything I have heard yet on solving the interstellar flight problem. I hope you can get some traction with it amongst the scientific community. Its as deserving an idea as any, to be developed further.
This channel is freaking awesome! May be my new favorite channel
This channel is incredible. Keep up the great work!

I love how the thumbnail is stellaris
could you redirect the push into rotation so that a station in orbit can harness the energy using the halo technique? You could use the excess energy to rotate two or more flywheels like water wheels and the spinning in opposition would also add stability. the rest of the energy would have to be balanced against the gravitational attraction and maybe the orbital motion like a sailboat tacking. My other idea is using a lattice of lasers creating artificial hill sphere resonant nodes. Mmm yeah that's elaborate. = D
I had the same thought... you could use the beam energy to rotate massive fly wheel rings that orbit the black hole. Then you could pull the kinetic energy off of the orbiting wheels as needed.
Alright. So the Mass Relays network can be real, just add black holes instead!
Also I'm just so amazed by this concept, or generally by this channel.
It's like... It's like what we think of Leonardo DaVinci and his inventions he couldn't create because of lack of good materials, but for our future!
All the problems we humans have/cause on earth are kind of pathetic after watching videos like this. In the sense that we should be dreaming big and try to accomplish stuff as the human race instead of fighting each other.
David not for nothing but you are so cool! You are the best. These are fantastic concepts.
Hmmm, thinking big. So a globular cluster like Messier 22 for example with its black holes that happily coexist in close (relatively speaking) proximity could become a real jump off point to the rest of the galaxy given how nearby it is. Practically right next door. I'm thinking a coffee shop and a walmart.
That’s an interesting thought I hadn’t considered
Non Binary Halo Drive is an amazing band name
I wonder what would happen if you threw a 2*10^43 Hz laser at a spinning black hole? could it be blueshifted further? can light have a wavelength smaller than planck constant? uuuuh brain hurts....
Is that Planck frequency? That would be an interesting experiment. Sadly we have no idea how quantum and GR can be fused really, making this unpredictable
It would probably create a kugelblitz black hole
What if, just what if...suddenly our history books changed saying "mysterious laser beam hit Pentagon dating 1800's" the black hole is actually is TIME WARP or a TIME TRAVELLING portal.. hehe
ImagIne for a moment that we are one of the "first" in our galaxy, if we can map and use these black hole highways, and leave maps of the ones we've discovered, thousands/millions of years from then there might be races who discover those highways and wonder at who the race was in the distant past that discovered them. WE could be considered one of the "Firstcomers", one of the precursor races that paved the way for others to follow.
Kind of a cool legacy to leave long after we've gone, or advanced to beyond the meat bags we are now. Thanks Dr. Kipping, yet another video that makes me think, wonder, and ponder the future.
Some sound words at the end there
I honestly cant comprehend how light(something without weight or mass) could stop a ship weighing tons, moving at relativistic speeds 🤷🏼♂️ i think i need to go watch the breakthrough starshot videos on how they explain this concept. I dont understand how light could move an object
Don't take my word on any of this, it's just how my uneducated brain makes sense of it.
Light has energy, even without mass. If light is 'absorbed' by something, it's energy can't just disappear, so it's converted into another form, of which i guess one possibility is heat. Heat is essentially a form of kinetic energy, the 'vibration' of atoms. In the reverse way, hot objects emit light again, cooling them down in the process.
I have no clue what the loss factors are in the process of the creation of light in any of the ways we know of, or the conversion from light into storable energy of some sort.
E=mc2. Energy is mass and vice versa, correct?
@@JoshuaOhl it seems like e=mc2 is just oversimplified. A part of the energy apparently stems from 'momentum' which photons should have despite their lack of mass, but i can't wrap my head around the definition of 'momentum' of massless particles.
from what i read, the formula should actually be "e^2 = (mc^2)^2 + (pc)^2", where p is the momentum.
We're like cosmic ants lol
the sound track i hear in your every video is what I always used to meditate with. so right choice.
There is so much I could say about this page and community. But I will just say thank you for such amazing content and amazing community. I have found my people.
This channel should have way more subscribers.
Awesome vid and loved the Stellaris map galaxy map shots you all used showing the hyper lanes between the systems lol.
Hi, this was good, although the short movie clip you showed said "you want to go in to the Black hole?" - "In, Through, Beyond" (and it is here where my argument takes place, the use of the word "beyond" isn't a vector in space time, expand....
This channel is like Isaac Arthur if it had something to do with the actual universe we live in. Keep it up
Can't help but to buy into the Orlando to Cali analogy...Im sold. Seems very possible
I was skeptical until the railroad analogy. This sounds fantastic. Let's do it!
What about counter rotating binary black holes? Do they exist? Could you position spacecraft between them and create energy? I would assume that they cancel each other out if they are too close.
