@@MaddEndd hey not bad! Diffraction, event horizon, blue shift, I like it!! Fraser Cain is looking for images for his video too, can I send this along? The only issue I see is that the beam is emitted from one side but absorbed on the other, which would impart a torque on the spacecraft causing it to enter a pretty insane spin.

Regarding the torque, wouldn't that depend on the mass distribution on the ship. Granted I havn't drawn the ship so it is left to the imagination how it is designed. I had focused a bit more on the visualisation of the laser and the black holes. While I was doing that there where a couple of questions that popped up here and there. Does the spin of a black hole affect the laserbeam? Another thing, if we assume that the laser has a round cross-section, does the blue-shifted laser have an eliptical or maybe even egg-shaped cross-section? I actually have a couple more of those questions but that would push it a bit.

"cell's" I see what you did there

This gave me goosebumps. Thank you for making these videos. Here is a sort of a background story as to how big of a difference you've made in my life: I was having an existential crisis for a very long time, because I as many others didn't see the meaning of life. But not because of an bad event or because i was not working hard towards becoming better (and not having many opportunities to evolve), but rather because I had no dream, no final goal. Since I can remember my sole goal was making my father proud ( not that I did not love my mother, but she was always satisfied with whatever I did while I had to work to get praise from my dad). I aced my way through mid school, then high-school. Then I entered an Electrical Engineering program at a Dutch University and kinda got to the point when my dad was also constantly happy with me. The constant work load kept me busy, but I was empty. i aced my third year as well and reached year 4 and my father passed away form cancer. ( that's October 2018). What that did was kinda allow me to evolve to a whole new level mentally physically, but still. what was supposed to happen just continue grinding hoping that my dad is watching? I still had no particular purpose. I had to take a break from uni for half a year to fix the mess due to my dad's death (in my home country).So I did some soul searching in my free time and I stumbled across your video on the Kardashev scale. I think the video(as in you) gave me purpose in life. Like legit. (and also helped my choose what I would do for my Master (in other words I will go into renewable energy, for example)) You gave me the dream of helping our race progress towards Level 1. Because yes I was acing my exams, but i did not know what I wanted to do with my diploma afterwards. I don't know why I want this (progressing us to level 1)( probably my ancient monkey brain wanting me to help the tribe), but the feeling of knowing what you want. I think that by showing me the scale of things you helped me expand my mind even more. They say that in order to prevent a mid age crisis one must choose their goals to be abstract and unreachable ( and I was searching for a goal like this for 2 years, but being healthy and strong and following the Bushido code was not inspiring enough, or as much as this is). I have always been fearless, but now I am afraid that I may not have enough time to do as much as I want to towards this goal and this is probably what inspiration means and motivation. Actually wanting to be alive, because it would allow me to maybe create and/or witness something Great ( maybe a bit of the cyberpunk age). I was never a fan of cosmic travel, because i was not aware that so much was actually possible, but after watching this video I feel like I've unlocked this passion that I had kept down and its amazing. I know that I may not have time to know everything that I want to know, but I will do my best to push our civilization forward. (starting to repeat myself :|) Now, I have never posted a comment on youtube, might be a dumb idea, but I thought that maybe I could express my gratitude and kinda give you insight into how big my gratitude is with the whole background story paragraph. ( Also I am kinda writing this at 00:05 and I hope that when i read it in the morning it would make sense at least at the key points) ( I will cringe so much in the morning)( no I am not under the influence of any substance) ( I am having a very hard time pressing the send comment button, but if I spend another 20 minutes looking for writing mistakes I may not send it so here it goes)

Aside from all of the other issues which you mentioned, the major problem would be, slowing down once you reached or got anywhere near your destination. Hoping that such an advantageous double-star system would be near enough, or in reasonable proximity, of your destination would likely make the destination choices relatively limited. Regardless, a novel idea, & your visual portrayal was quite sufficient for me to understand the concept.

@@imtoouncreative8263 You have a valid concern. The energy to decelerate the spaceship from approaching (against the gravitational field) is way higher than the energy acquired from the coming back photons, or at least equivalent. Because the energy used for decelerate is going against the entire mass of the spaceship and the black hole(s), while the energy increase by the laser beam is pretty much massless. I'd like to see the calculation of the comparison between the two.

Very cool idea. One issue that occurred to me, though, is that tight black hole binaries don't live very long. Black holes binaries with a semi major axis of ~3 solar radii will merge due to gravitational wave emission within a Hubble time, and the orbital velocity of such a binary would be comparable to the escape velocity of the sun ~300 km/s (only a factor of a few larger than the velocity of stars around the galaxy). In tighter binaries the lifetime scales very steeply with semi major axis (I think it should go like t~a^4), while the velocity only scales as v~a^-0.5. Therefore, it seems that tight black hole binaries are going to be rare.

The laser fired from the ship towards black hole will firstly redshifted in wavelength and then the laser turn around from the black hole will then experience a blush it as it is moving away from the black hole, so over all in brief , the laser is keeping the energy conservation.

@Coloursv7

5 жыл бұрын

But since the blackhole is moving relative to the ship the time spent redshifting is less so than the time spent blueshifting, ending with a higher energy beam than you started with until the ship is moving at the same velocity as the blackhole at which point you reach equilibrium where redshifting and blue shifting are equal but you still have all the fuel/energy you started with plus more. Energy is still conserved as in this process as the blackhole will lose the energy which you gained.

Hi, this video blew my mind when I first saw it, and I just watched your interview on Event Horizon. I'm wondering: how hard is it to target the laser accurately enough for it to take this geodesic path back to you? Could we build a Halo Drive with current technology (ignoring the problem of getting to the nearest black hole)?

I love your channel! Really inspiring and simultaneously mind-blowing

Absolutely incredible work, thankyou for sharing!

Great concept, thanks so much. If an alien civilization was using a system like this, would we be able to see it? Would we see a bright flash or something if the beam crossed our path? Or is all of the beam absorbed or reflected by the spaceship? Interesting to think how this might be detected.

It’s an ultra efficient system so not much leakage... the best bet is seeing an increase rate of binary mergers beyond that expect naturally

Interesting concept, but whatever miniscule energy you get from the returning beam, will be offset by the immense energy you have to spend to escape the gravitational pull of the black hole. Unless you are planning to use this from far away. The nearest currently known black hole is some 3,000 lightyears away. So good luck waiting 6000 years for your energized beam to bounce back :)

Isn't it possible that the initial "push" from the laser beam cancel out the energy gain from the laser after the slingshot? thereby gaining no net energy. Also, how would one capture the laser energy back since the push from the laser would cause the craft to move and not be in the same position as before?

yeah you would need to account for the initial kick that firing the laser gave you and thus fire the laser slightly further away from the exact boomerang geodesic but it would still work.
