As you can probably tell, I struggled with finding a good illustration of this thing! If you have some artistic talent and come up with anything let please message me!

So, you wrote a paper. And then made a video about it on UKposts. In the spirit of open science I really hope this will happen much, much more often in way more fields. People need to know whats up in the labs and see the great minds living there.

Dude I felt every single word of that childhood story, I still look up at the night sky almost every night wondering whats out there.

But that's ok, sometimes the dream is enough. The dream is enough to keep us inspired... Thank you for sharing your dream, David!

The interstellar soundtrack is just ❤️... Goosebump moments!!

If i'd have had this guy teaching physics at school, i totally would have gone into physics for the rest of my life. Thank you Prof. Kipping.

I love your videos, Mostly because you easily explain complex ideas, but you don't dumb it down so far to where it seems to kill brain cell's

This man is absolutely captivating, makes me miss college like crazy

I could literally listen to these videos for hours. Very soothing but also extremely accessible and engaging. Brilliance in speaking like this is an art and the passion displayed for the subject matter is truly inspiring. Thank you!

I'm impressed. So simple and common sense according to our current understanding of physics. I wish you much success and hope to see you find a way to test a proper theory for it! Well done sir!

Im so glad this video was on my recommended. Subbed instantly. Please more videos like this. I love the Interstellar music when u explained the slingshot.

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)

Beautiful! We need more ideas like this. We’re surrounded by free and vast amounts of energy. We just need to harness it.

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.

I found your channel this evening. It's 2:45 am and I'm still watching your videos. You're one of the best teachers of these concepts in a way that the average person (like me) can mostly understand while still appreciating we are just being shown the very very tip of the surface of its complexity that I've ever seen. Subscribed!

Congratulations for reaching 10,000 subscribers !

I’m really honored to find this channel! Your insight and your discoveries are simply amazing! Thank you so much for sharing with us mere earthlings! God bless people like you that can see outside of the box!

I like that there's one of one of the pieces from the Interstellar soundtrack in the background

wow !! so refreshing to see someone ( on UKposts) propose an idea and have it backed-up with a written paper that can be peer-reviewed . You scientific honesty does you a great credit

Most of the videos on space/the universe makes me fall asleep but yours keeps me ingrossed

I can't believe I haven't heard of this man,or theory. This is genius. Revolutionary.

So basically we need to build a few mass relays and scatter them around the galaxy and have a central citadel to control them all.

This man's voice is so relaxing and soothing. I drift off before the end in a sort of trance. He is great though.

What a mind-blowing, fascinating idea for an alternative drive for space traveling! You have the spirit of an intellectial pioneer. Thanks so much for sharing!

Your videos are very emotional and compelling. Thank you for another lesson :-) Subscribed!

This guy's channel is absolutely great, love the material selection. Excellent, easy to follow, clearly articulated presentation for a layperson. Just awesome.

7:13 In short, the Dyson Slingshot is not for the faint of heart... 10:33 The light skims the event horizon ...loops around and actually comes back to you." How cool is that?!? Great video! Thanks for making!

Good idea. And important for SETI too. I'm not a scientist, but I suppose that Astronomers can look for life possibly moving along black hole highways in any galaxy. Can even make a map! Theoretically, life could be spread out across an island chain in the galaxy between these black holes, like an archipelago

This is the most interesting video I have watched about anything - many thanks Prof Kipping.

Thanks for the wonderful video david! Love your clear presentation and well laid out thoughts! This was my first video of yours and cant wait to check out the rest! And I love your idea about your dreams!

I had the same dream growing up during the Apollo missions. The Halo drive sounds like a great concept. You may be the equivalent to Zephram Cochrane, inventor of the warp drive in Star Trek! Great vids, keep up the good work.

Laying out under the nights blanket of stars listening to your words . Magic.

This channel is my favorite discovery of the year, such amazing content and so well explained ! Mind blown

the conclusion almost made me cry . love the concept #HaloDrive 😍

I'm so glad I found this channel. The work you do is amazing.

I like the fact that you try, the best humanly possible to be honest and unbiased as possible, and that's why I subscribed.

Wow !! I have now listened to this video in its entirety ! It's very well explained , even I easily understood it ! I am most perplexed by the number of dislikes , to me it makes no sense at all !

Fantastic! Someone will surely use the ‘Kipping Halo Drive’ one day! Bravo!

That was amazing and has actually blown my mind. Thank you Sir for sharing. So glad I've found your channel.

Brilliant. Absolutely brilliant. Sometimes it's taking existing ideas and looking at them a new way. Also gives a target for future observations like unusual activity near binary black holes.

Just brilliant! Astrophysics is so beautiful. I'm in love with this YT Channel. Congrats.

This presentation's quality is top notch! And the idea itself is also great. At the very least it keeps the dream alive!!

While I have nothing of fundamental value to add to this lovely concept so brilliantly explained, I would like to thank you for sharing it with all of us. I look forward to to seeing it brought to life in film in the very near future... As it seems as simple to understand as it was difficult to calculate. Hope you'll continue your work on the UKposts series, as they are most enjoyable.

I'm new to the channel, but I have watched most of the contents already. The way you explain things are amazing. Its always a blessing to be inspired by such an amazing mind.

Most certainly a brilliant idea Sir. Well Done!!

Great concept and beautiful video. It’s also interesting to think about possible technosignatures around binary black holes.

This is an incredible video. Thank you very much sir. I truly appreciate this. Especially today after seeing the very first actual picture of a black hole.

I only watched one of your realizations and it so captivated me that I subscribed right after. Thank you! I will share them to the world. Wonderful job!

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.

Why am I crying? Thank you!!

That was one crazy concept explained surprisingly simplistic. I'm almost not sure which of these is more impressive. Either way, after seeing only two videos of this channel, I already love it.

Brilliant. I always get emotional with these videos. Thank you so much Dr. Kipping.

Great stuff as always, David. I have that dream too. Thank you.

Congratulations on such a well made, informative and fresh science channel, you've just earned a sub from me, I only wish I had more scientifically minded friends to share your great channel with!

Completely hooked and binge watching. Thanks for the information

your videos are like therapy for me

Best channel you may happen to discover through “recommendation”. For once, well done to UKposts!

Wait, i have a better idea: *you cannot fast travel when enemies are nearby* Damn it

I absolutely love your channel. I understand only about 10% of the subject matter, but the way you talk about it, along with the soundtrack is absolutely fabulous. I've even got my wife listening to you. We jump in bed at the end of the day and just listen to you. We learn a bit and get completely relaxed. Win Win!!! Cheers!

Everything was on point..... Really loved the video.... It's soooo explanatory.... Thank you for sharing your dreams.

AWESOME STUFF MAN!!!!! LOVE IT

Wow! Very cool video I love your videos thanks for this it really fuels the imagination.

Long live. I also wanted to touch the stars. Still now, often at night, I look up at the starts and wonder. I know I can't touch them... but via your videos my childhood dreams get a new meaning. Please keep uploading such videos.

And a scene from 'Sunshine', best sci-fi movie ever :) Love ur thinking and explaining.

🎯You are exactly the kind of UKpostsr I want to listen, I personally Boost my General Knowledge with these Types of Video content📈 thanks Teacher🎓

This leaves the problem of decelerating on the other end -- you would have to aim at ANOTHER pair of orbiting black holes and do the same thing when you arrive

Absolutely incredible work, thankyou for sharing!

Amazing intelligence but greater of a story teller. Your ability breakdown enormous amount of information is quite incredible so thank you! Map out these black holes (halo drive “stations”) and create a highway system, as we did in the early 1900s. We first created local then Interstate highways, and built gas stations along the way so travellers could reach across the USA. Is that the similar concept??

Excellent video, I'm now a subscriber. Nice work.

This inspired me to go look at the stars. I saw nothing but clouds because I live in the Pacific northwest.

Elegant. Beautifully presented. Thank you sir.

i just keep coming back to this video, it excites me so much just thinking about this whole concept, i love it!

Really thoughtful and clear video David, awesome!

I've just read "Collapsing empire" by John Scalzi and it blew my mind :D Your video also blew my mind. It is all amazing

Excellent vid ! Informative AND the music effect was soft and effective. THANK YOU !

Explanation is so simple. Loved it.

Great content ♥️!!

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 :)

I have to say, as I have said before, I don't understand the full extent of what you are saying because I am not intelligent enough. But I do certainly understand what you are feeling in your words. You have heard this many times, I am sure, but you have the type of voice, that makes people want to listen and learn. I am in my 60's and enjoy being taught that you are never too old to learn, and certainly enjoy. Thank you.

Great explanation on using the slingshot procedure to increase speed. Thanks.

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.

I had the same thoughts as a teenager, that I wouldn't be able to travel in my lifetime and missed the window, but I hope for people on Mars and testing the frozen water moons for life in my lifetime......

Professor David? You sure deserve lot more subscriber. Easy to listen and easy to understand the maths when you talk about them. . I wish you could be in the next program/series of Cosmos!! Carl Sagan will be Proud. Seriously🙂🙂🙂

Wow! You are amazing. And I really like the way you present information, not so much technical, but yet so scientific and precise. Keep on posting videos like that! I enjoy watching, one of the reasons because you are not mainstream like scishow e.c. And you really know what you are talking about! I subscribe! :)

You Sir, are amazing. Maybe you WILL live to travel the stars. We never know what tomorrow will bring.

Great! So all we have to do is get the spaceship to the binary neutron star. How do we do that?

One of the best videos I've watched in the past year.

Your work here is consistently excellent and enthralling. Thank you from all of us.

Before aiming for the stars, perhaps we should first learn how to transfer our consciousness to a more spaceflight-friendly container.

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.

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

I can listen to you for hours!

Ambitious idea, ISRO used slingshot to put a satellite just above the orbit of Mars. The only shot we have is to have a giant spaceship with fusion reactor, ion propulsion. Ion propulsion start slow but have multiplicity factor, at certain point we will reach near light speed. Problem is we have to slow down too, survive softball size meteors and radiation etc. To pull this off we need eons the tme.

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?

These videos are such high quality. Please make more!

Amazing video and explanation. Thank you for doing it.

He’s great at this niche. The open minded science plus his storytelling makes me feel smarter than I am 😂

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)?

Subscribed, notifications on. I'm coming from your earth telescope video. I'm very impressed. I can't wait until one of your ideas (already existing or soon to come) gets implemented!

You had me at way points. Beautiful.
