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

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.

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 KZread videos as cosmology and astrophysics, but I can imagine steps in this direction at least.

I’m being taught by an actual genius, never stop making these videos please.

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.

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.

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.

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.

I am so very grateful to have come across your channel. I love the content and How it is presented

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.

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.

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!

If I restrict it to those who also post sources then it would be the following: - What I've Learned: kzread.info/dron/qYPhGiB9tkShZorfgcL2lA.htmlfeatured Mostly about diet and food - SmarterEveryDay: kzread.info/dron/6107grRI4m0o2-emgoDnAA.html A lot of slowmotion video analysis of various awesome effects. - maiLab: kzread.info/dron/yHDQ5C6z1NDmJ4g6SerW8g.html A German chemist who does videos on various different topics and also fact checks other channels from time to time. - Today I Found Out: kzread.info/dron/64UiPJwM_e9AqAd7RiD7JA.html The name is program. Basically explaining a multitude of different topics that you mostly don't even think about. - minutephysics: kzread.info/dron/UHW94eEFW7hkUMVaZz4eDg.html Explains a lot of math and physics related topics with cool drawings. - Medicurio: kzread.info/dron/OU-lyJtyRZ5yvjPk1th7uw.html Explains various health related topics from a medicinal point of view (sadly hasn't uploaded in a while) There are more channels I watch that don't necessarily always have sources or that do more documentary style videos like e.g. Veritasium (kzread.info/dron/HnyfMqiRRG1u-2MsSQLbXA.html) or Everyday Astronaut (kzread.info/dron/6uKrU_WqJ1R2HMTY3LIx5Q.html) who explains a lot of rocket and space flight related topics. I also like to watch Isaac Arthur (kzread.info/dron/ZFipeZtQM5CKUjx6grh54g.html) who explores futuristic ideas based on current day physics (you do have to dream right :) )

This channel is incredible. Keep up the great work!

Awesome vid and loved the Stellaris map galaxy map shots you all used showing the hyper lanes between the systems lol.

Very interesting video, and Dr. Kipping has a great voice that's pleasant to listen to. Very enjoyable.

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.

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.

I love how the thumbnail is stellaris

Absolutely love this channel - thanks so much for posting!

This channel is incredible! I've never felt so inspired and so stupid at the same time!

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.

Excellent. Always enjoy the work you do to make these videos. Thanks

"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.

Awesome video. I started thinking this would be some futuristic fantasy, but along the way it turned out to be something that could be realized, and could have some short-term (in our lifetime) rewards. I really enjoy your videos. Please keep them coming.

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.

Can't help but to buy into the Orlando to Cali analogy...Im sold. Seems very possible

Love this channel. I’ve always been fascinated by the unknowns of space.

Came for the Stellaris thumbnail, stayed because I couldn’t turn it off. Needless to say I’m subbed

WOW... just... WOW!

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.

Incredible content yet again. Thank your Dr Kepp

COMBINING THIS WITH THE STATITES AND QUASAITES IDEA ... COULD LEEAD TO INTERESTING RESULTS...

Oh man this stuff is better than SciFi!

Love Kipping's videos....simply fascinating!!!...

Third video of yours I watched, definitely earned my subscription. You're doing a great job pal 👌🏼

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.

I feel like my brain has doubled in size just from this video.

@@CoolWorldsLab Thanks for taking the time to dumb this down so well for someone like me. It can't be easy. Every time l started to wonder about some issue then that was the next thing that you brought up. Your clear and measured pace of speech really helps the concepts sink in as well with a nice flow. I wouldn't be suprised if your subscriber count takes off one day. Cheers.

This explains why you understand our universe so well, you are the one doing research on it!
