Turning Earth Into a Telescope | The Terrascope
Вставка
- Опубліковано 1 тра 2024
- When it comes to telescopes, bigger is better. That's why we're investing billions of dollars into a new generation of "extremely large telescopes", such as the Thirty Meter Telescope (TMT). But is 30 meters truly extreme? Could it be possible to ever build a telescope on the scale of a planet? In a new research paper by our very own Professor David Kipping, a solution for turning the Earth into a "Terrascope" is presented. Join us on a journey though the history of telescope inventions as well David's own personal journey to devising this new radical approach to the telescope.
Written and Presented by Professor David Kipping

#Terrascope #EarthSizedTelescope #CoolWorlds - Наука та технологія
You and your channel are partly responsible that I picked up my old and greatest passions physics and astronomy again. And now I am going to start my bachelor in physics at university this autumn. Thank you for your inspriation
That’s amazing, best of luck!
MIT has many of their calculus and physics course online. Includes homework assignments, tests, etc...
Non-accredited of course.
@Boris Cuduco It helps, certainly---but of course you're wrong.
What's the deal with the urban legend/myth that the Vatican has an advanced telescope named "Lucifer"?
Indeed, it's never too late.
A scientist is nothing but a dreamer, if legends had not dreamed, we would not be here today. I truly enjoyed the passion you posses.
Bravo. Not just dreamers my friend, but they are in touch with the Universal Consciousness. Most great minds are, the Universal Consciousness can be touched much the way you tune into a certain radio station. Not every human can do it. Much the way you feel a loved one in danger, or you know a friend is calling before you pick up your telephone. It is energy and bandwidth. Thank you for your reply!
Actually a scientist is an analytical person driven by the facts and building on what those who have come before them have done

The terrascope is a great idea, although it was already proposed by Yu Wang (NASA) in 1998: ui.adsabs.harvard.edu/abs/1998SPIE.3356..665W/abstract
@@doctorpapoofnik1535 your head is not a fucking radio transceiver so shut up if you don't have any real evidence.
An incredible idea. The elegance of it is frankly stunning. The cost of placing things into space is plummeting and placing a detector at a LaGrange point is very doable for NASA, ESA, JAXA, or the Russian Space Agency so hopefully this will go somewhere (literally)
One of your crucial points was that a single professor recognized the potential of your idea and apparently encouraged your pursuit of this. Imagine if he had poo-poo'd it instead. There is the other real story - we must not only educate the younger generation but also encourage their successes and help them learn from mistakes that everyone will make. That is the way forward for humanity.
This was indeed an amazing 30 min journey. I'm literally speechless on the concept, presentation and emotion presented. Your students are amazingly lucky. Instant subscribe.
The terrascope is a great idea, although it was already proposed by Yu Wang (NASA) in 1998: ui.adsabs.harvard.edu/abs/1998SPIE.3356..665W/abstract
Thanks for the Subscribe reminder! good idea. GLT's are the future! ;~} (Gravitational Lensing Telescopes) I BET _'THEY'_ ALREADY SEE _'US'_ USING THIS TECH!
As an ordinary guy with little interest in astronomy,I found myself gripped by this presentation. Well done! I truly hope that your theories are put into practice.
Best thing about your vids is that you're not just spitting out what someone else wrote, you know this inside and out and can explain it beautifully, I love a challenge and I love to learn and your videos do both, keep it up mate incredible content :)
Thanks Jeff, yeah I always try to follow my own path in whatever I do and so my UA-cam channel does the same. Let's get researchers to talk about research! I don't think that's so crazy...
@@CoolWorldsLab Most of the greatest inventions and discoveries were byproducts of crazy ideas anyway so I wouldn't judge a crazy idea anyway. I also wish you the best in your future building career, not long before one of these are put into practice and change the world.
David, your coda for this video caught me at a sympathetically introspective point in my life. I'm 70, just retired last year after 40 years practicing medicine. The retirement wasn't voluntary, rather driven by a smallish stroke, a clot from my heart going to my cerebellum. The residual isn't very obvious, but my memory and attention have suffered just enough that it was unsafe for me to try for my long-planned retirement at 80, a half century of work. Oh well.
When I was 30 I had dreams, analogous to your first terrascope musings 13 years ago. Some were realized, some weren't. Life often got in the way. I've given up flagellating myself for the failures, and instead pat myself on the back for the successes. Some of those ambitions might have been fulfilled earlier, maybe, but it's just as true that some could have been later, or not at all. Look back 13 years - do you now have better ideas for how you could have worked around not having job security, money, street cred, infrastructure to support your vision? I'm guessing not, because if you did, you'd be telling US how to do it. But ultimately you're right - do your best to do it perfectly. But when, inevitably, you land somewhat short, take it and feel good about it.
That’s also very true. I think the best approach is just to accept failure is a part of life, but follow enough threads and one or two might just work out. And if everyone does that, we’d be riding a revolution every day.
Boy can I relate. I'm also a physician forced into early "retirement" for medical reasons. "Life got in the way.". I think John Lennon said, "Life is what happens when you're busy making other plans." Thanks for sharing your experience!
I read an article about the Wasserman-Wolf problem (spherical aberration) being solved only last month and presumed this video would be discussing that. Alas, not only has that been solved but this 13 year-in-the-making piece of work arrive at a really interesting time for telescopes (now terrascopes!). Your videos truly make me believe humans can prosper in the future but we need scientists in positions of power to steer us on the correct journey. Scientists and educators like David are the people who will take humanity in a positive direction.
As a fellow (yet to be) researcher (I have started my PhD), I really like your way of presenting your work and making your newly published paper available to everybody. This is how science should be! Your videos are very inspiring and your ideas are fantastic. Huge respect...
Kipping is a contender of being the modern day Sagan.
We'd have to audition him on his rendition of "billions and billions..."
@@OslerWannabe Oh absolutely!
Yes, I totally agree....
The terrascope concept is really amazing. And I can relate to your almost lost ambition that finally has come to fruition. I relate because I have had a similar but somewhat worse experience. I am a pediatric oncologist in an underdeveloped region of an underdeveloped country. For me, to achieve what I have now was extremely difficult, and not only I had all the social and economical barriers in such a place, but also most people judging and saying that my aspirations were futile. When I started, the first one to ever consider specialize in neuro-oncology in my institution (the only one caring for kids with cancer in a place bigger than UK and with many millions of inhabitants) there were less than 10 ped brain cancer survivors in our follow-up. Now, there is 100+, and the number grows by the day. Every single life that I changed, every single dream of a kid that could became reality simply because they were alive to go after it, every one was sufficient for me to know I had won, that I had accomplished what I had dreamed. So much people that turned their backs on me, so much "great specialists" that have told me "It will fail". My will was almost broke so many times, and yet I had to crawl, almost strengthless, I had to cling myself to a feeble hope, I had to carry on, for the kids that I had lost before, some of whom died in my arms. Now I am profoundly tired but profoundly satisfied contemplating what I could make in this life almost alone, except for my beloved partner and familly. So, thank you for this vídeo that made me remember so many things and cry, knowing that as you I was one of the few privileged in this life, I have so much to thank the universe for. Have peace, and again thank you.
It is truly an honor to have the opportunity to learn from you, amazing quality and execution, a scientific role model! You truly honor the scientific method, no other channel comes close to such quality! It would not surprise me to see you being in the lead of the next space telescope project, let's just say that!
Thank you so much for this work. the best 30 minutes i've spent today
Thanks!
Thank you. 👏👍
My best 30 min today was in the restroom.
Same here
@@CoolWorldsLab Fantastic project, David! Thanks for sharing it with us on this channel.
Having dreamt of becoming an astronomer all my childhood, which I finally turned out not to be, your videos are for me a great way to reconnect with the wonders of the sky. I appreciate not just the brilliant research work that you and your team does but also your personal commitment to share it with the lay persons we are. Your presentations are always were clear and didactic and your storytelling talent a delight, making you not just a brilliant scientist but also a truly competent communicator.
One single regret. Recently your channel added background music to its videos. It is not necessary! In my opinion it is even distracting. Your presentations are self sufficient :)
This terrascope concept should be done, this is amazing. I thought we were hitting the ceiling of how big we can make telescopes.

Very cool. Thank you for taking the time to share your research! It's very rare for professors to have an educational UA-cam channel, let alone one as high quality as yours.
Thanks guys!
I'm an astrophysics major at UCLA and I absolutely love your content. You're videos are so intricate and captivating. Please keep it up! Really gets me stoked for my generation of astronomy 🙏
Wow thanks Erick that means a lot - consider Columbia for grad school if you decide to apply!
Go for it! I retired from 'work' at 70 years old. I've been having a creative ball ever since.
must be nice
It is. I'm getting radical and turning into a nerd. Growing old disgracefully take time and effort.
I retired at 32 and I am 52 Today . Been having a pretty cool time of it ... Earth is Flat :) QC
lucky lad
@@QuaaludeCharlie Retiring at 70 is honorable. Retiring at 32 is obscene. preposterous. offensive. Certainly
nothing to be proud of... Oh,. I see from your last sentence, you're joining us from 10,000 b.c. ... I HAVE TO KNOW: RETIRED FROM WHAT? WASHING WINDOWS? _'BRAIN SURGEON'?_
So, if this process provides a 50K flux increase, then when observing systems with exoplanets a 0.1 second exposure provides the light gathering results of a 1.3 hour exposure. During that time the atmosphere can't move much so while there would be atmospheric distortion, there wouldn't be any motion blurring.
I'm thinking that you should be able to get close to the theoretical resolution of the earth-diameter system by taking each .1 second image and applying a convolution to turn the slightly blurred dots of the stars into point sources and then stacking them as amature systems do using webcam images.
If that's right, then you should be able to actually directly resolve exoplanets with a very small telescope on orbit. A quick back of the envelope suggests that a 3 unit cube sat with a 10 cm lens similar to the "Flock" sats should be sufficient. If that's right, you could fly a "flock" of Terrascope sats for very little money.
It might be worth proposing a single sat testbed to the nice folks at Planet Labs.
I'm not going to pretend to have understood what you're saying but, assuming you're not talking nonsense, it's great for a mere mortal like me to see bright minds in action and working together.
True
What does it mean in reality? Could we see an exo planets relief surfaces like continents and oceans if it has one?
I dont have the required knowledge of physics, or astronomy to understand these complicated words but im happy that at least some humans are actually intelligent
Hrvojo, it sort of depends... the diffraction limit of the "lens" is of a lens 8000 miles across, but the atmosphere is always distorted, so distant stars will be smears instead of point sources. You have to use software to unsmear each image by forcing those distant stars into single pixels. Then you stack them. Theend resolution depends on the accuracy of your software and how smeared the image was. I could do the math, but it would be little better than my guess.. which is yes.
Hi David, I've been using UA-cam since the mid 00s and this is probably my first comment in all these years. This is the first video of yours that I've watched.
Thank you for putting this together and explaining your idea so clearly. It really is an exciting concept and I hope and pray that you live a long and happy life and get a chance to build a terrascope or atleast see one in operation somehow. (Hopefully I get to see it as well! Inshallah.)
I really admire your patience and perseverance in researching this concept and your message at the end about not waiting to chase our ideas/dreams really hit close to home.
Your video is very wholesome in that regard and the way you presented your ideas evoked an intellectual humility that I have only sensed while watching Carl Sagan's videos.
Keep working, making educational messages and may you see your work in action someday soon! Good Luck!
You have a true gift for making stupidly complex topics both easy to understand and entertaining, your passion is infectious and makes me excited for science and space. Can we clone you?
Thanks Andy - I feel the same way about Sagan, Attenborough and Feynman as communicators. I don’t think we need clones though, as great as they were, because each new voice adds a new and fresh verse to the song :-)
@@CoolWorldsLab seeing your videos reminds me of Einstein in regards to the fact you are able to deliver it so simply. But if im being honest more so Leonard susskind in the sense it would be a pleasure to just sit down and have a drink with you.
Love your videos, and congratulations on getting your idea submitted!
In one response you said "each new voice adds a new and fresh verse to the song ", let me tell you David, you are the best singer for me. A big hug from Uruguay.
The earth isn’t flat. Its telescope shaped. Take that globe earthers.

The sense of urgency is never too late. Hats off to you and keep the torch lit...
Wow, I thought I knew all the astronomy and futurism channels on youtube. How have I not seen you before, amazing content!! Fortunately I broke my foot so I'm ready to binge your channel well into the night. I legitimately feel lucky for this. awesome!
Glad you found us!
So well explained that I could see where he was headed at each step before he got there. An amazing educator.
Thanks!
This is gaining traction in so many scientific circles now outside of UA-cam. It's amazing everytime I read about it and I think of this video every time.
Excellent work!

Bravo for your response. You are correct to your point. This man here, Professor David Kipping, take science to the level of the Great Carl Sagan. In fact.....Professor David Kipping is the next Carl Sagan! Amen!
Yes. I think it would be easier to build than the solar gravitational lens FOCAL.
Inspired. The thing I'll take from this is to never forget your dreams, thanks for that.
ummm... sure 🤔
@@ntactime_w3488 clearly the concept is epic however dreams do come true, just ask Gabrielle.
I appreciate the words of encouragement you gave at the end of the video. You're a good man. I wish you the best in your work on this terrascope.
UA-cam recommended your video. And it was simply amazing. I tought it was another documentary that would end talking about some near future sci-fi tech, but when you showed your paper and study, i was shocked. This is something truly incredible and most of all genuine and inovative. Shows how a commom concept about bending light, can lead to bending light with gravity and then the atmosphere for building a telescope. You are what humanity looks for: someone who can transform existing old concepts into better, effective, cheaper and more useful things for society. I felt deeply touched buy your story.
I watched those final moments with a smile at my face and a sensation of joy for all the headcracking moments you had and that it finally paid off. I can feel you’re realized because of such great outcome for you work.
Thanks and keep going dude
Cheers from Brazil
Gregor-just wanted to say I agree, and I think you would love all the other Cool Worlds videos. They’re incredible.
Outstanding concept ! Great advice at the end of the video , certainly made me think about things.
Thanks Andy, I appreciate you tuning in!

Fantastic presentation and a great example of dumbing down science for average janes and joes.
Thank you!
Pioneers are what makes humanity be noble and I hope you achieve this project.:)
I had these dreams but unfortunately left it too long to do anything about them. In the UK schools in the summer of 1975 I was (almost) physically forced to "drop my silly ideas and get a proper job". I got my maths degree and electronics too but it led me only as far as fixing peoples TV's & videos. I 'branched out' just to earn a living when I should have gone back to Uni' at the tender age of 27. I didn't push the point hard enough or have the confidence in myself to really start learning again. I could go on on but the essence of my message is, please do not wait and unless it is extremely positive advice, ignore people and go for your goal. Do NOT end up like me........Really too old at 61 to change my life for the better. I have a house and a mortgage and nothing else. I seem to spend my life cursing myself for leaving it all too late. DO NOT do the same! Follow your dreams and you WILL get there in the end. Thank you yet again for a very important & imformative video which in true Carl Sagan style makes it possible for the layman to understand. This was his special gift to us all and I beleive you have that very same gift...........Cheers.
It might not be the best option to advance in astronomy or the most valuable one, but I think we can all agree that this is so cool and the concept it self of using nature and universe as tools instead of making our own tools is really inspiring and makes me think that a lot of time we don't have to go so far to find a solution, we just have to think smart. well done sir 👏
Fascinating. Congrats! I too believe the key to unlocking many cosmic mysteries is working with nature itself.
You got it. We are a part of nature and we have to learn to work with it, I think that harmony will unlock a bright future for us.
Over the last two decades, I have literally watched thousands of people present videos.....this is the first time I have ever subscribed.
I was personally very disappointed when I came to know about the 650 AU needed for utilizing Sun's gravitational lensing. Your video brought me out of that depression and is giving us hope. I am wishing you all the best for this to succeed. May this be a turning point for human space exploration
But the video about that sun lens telescope explains a lot about how to process the image, how to collect the light, how to engineer such a telescope in less time with much less "me myself and I"
Turbulence in Neptune's colder atmosphere might be closer to Laminar flow, its also a larger world and much darker out there and less light pollution from civilization or light that is reflected off other objects.
Great remark! Yet Uranus looks like a better pick.
Uranus is only half as far away. I would start there if good enough. I agree though that bigger is better. Jupiter is much closer and much bigger, but turbulent as you say.
One of the best space vids I’ve watched in a while (and I watch a lot)
Can we start a petition to have this terra scope research funded?! Brilliant idea. And don’t be so hard yourself. You’re teaching millions about science and in a week’s time I’ve already learned so much. From your Long Island neighbor - cheers
The last 8 minutes brought tears to my eyes; I'm 66 years old now, and there are a couple of young dreams I never pursued... I hope your advice encourages many younger persons to re-evaluate their priorities and chase their dreams while they can...
This is amazing work, strange that I was looking up how telescopes are created and function just weeks beforehand, but thinking about using gravity as a lens was outside of the box. I applaud you good sir, sometimes all it takes is a different way of thinking to revolutionize an area of study.
You truly are underrated. Wishing for your channel to exponentially grow on a daily basis.
Thanks Nardi
Probably the most motivational, inspirational words I've heard so far! This video was great!!!
I don't know how I stumbled across your channel, but I'm so glad I did. I'm not well versed in astronomy by any means, but just listening to your ideas and presentation is inspiring to me. Thank you.
Beautiful! Thank you to the cool world team!
The musicality of your clear voice and sharp diction, the time you take to build up and catch our attention, the smooth combination of poetry, science fiction and dreams with hard science ! It’s beautiful, it’s how to make something as simple as possible but not too simple, it’s highly pedagogic, it’s generous. So yes, you already managed to create the most powerful halo drive imaginable: inspiration, indeed David!
Thank you for this energy.
Yes its trou 👍its very original and cool Spirit😇👌🧠🧠🧠🗣
Is the sun focused by the earth into a spot behind the earth with the same effect, making a portion of space focus 20k - 40k times the power of the sun?
Could this be used for solar sails, solar power, asteroid forging or mirror redirected to mars for heating?
What? Not a single flat earther commented? How is that possible?
First time viewer, loved the video!
Thankyou David for sharing your ideas, your research dream with us from such a personal point of view. I too have a research dream that began in my youth where an idea came to me in 2002, my second year of university. That's 17 years ago, now. It has always stuck with me, motivated me and brought me real joy! As you say, though, life has its everyday, mundane, routine requirements that are low risk. All new ideas that go against the average of things entail some degree of risk, and I have found that I've had to take repeated risks to stick with my youthful ambitions. Sometimes bringing me to question whether I should be taking those chances at this point in my life. If ever there was a clear message of encouragement to keep going with these ambitions, your video discussing you accomplishing your dream is it! It literally brought me to tears as I could 100% relate to your story and felt less alone with attempting to do something similar, and felt greatly encouraged. Like your concept of a telescope that can connect worlds, I'm also greatful for UA-cam being able to connect like minds. Thankyou once again and good luck with your future endeavours. I've subscribed to your channel as I find it thought provoking. Melanie. ☺
David, is it possible to combine the refractive lensing of the Earth with the gravity lensing of the sun, to lower the latter's focus distance from 550 AU to something lower? Perhaps somewhere nicely in the almost stable L2 point?
Great idea Professor Kipping. Every time I'm at a star party with my 10" telescope, I only dream and think of ways of capturing more light. Yours is the less Sci-Fi and more scientific idea then mine - lol. Looking forward to your next video.
Thanks Mark!
Thinking back to my own academic career as a Master's student, I must observe that your students are extremely lucky to have you as their mentor.
I’m thrilled to have found your channel. Learning so much! Love your ideas, and how you explain complex theories in ways I can understand. Thank you so much! 👍👍
Fascinating prospect! I'd be surprised if this technology isn't prominent in our future.
Wow - you are an incredible communicator! You took a truly complex concept and made it so very, easily understandable. Your passion is inspiring. I don't know crap about astronomy, but you even intrigued me. I so hope you make this happen - you have many years left my friend. Don't worry about the time it took you to develop the idea. Those years were not wasted, but an investment in creating your security and learning how to work within our human system. Now you have the skills to make it happen. So make it happen, now!
Great attitude! I'm deeply interested in your field of work! Good advice at the end. Thank you!
Your dreaming and the effort you put on this project is so beautiful that it ended putting me into tears. Somewhat witnessing at first hand this evolution and process of researching, imaginining new possibilities and following an idea that came out of your head, has been something I didn't expect to watch this close, I wasn't expecting for someone to put in video for me to watch their projects and developments this openly and while still ongoing, it made me too emotional. The thrill of discovery is really something else, taken directly from dreams, I did not expect this.
I'm already subscribed, but I'll make sure to stay close while your projects are ongoing. Scientists displaying to the world personal endeavours like this is something that should definitely be more common. I don't know the best wording to express this all, but my deepest thank you for this and what you do.
I enjoy listening to pop science youtubers, but, as a science man, I enjoy listening to actual scientists more. So happy for you, man!
Thank you for being so generous with your time and knowledge. I love following your journey. 🤓
Brilliant idea. This is one of those "why didn't I think of that" ideas, that you know someday will become reality.
Hi David, I'm a subscriber from Italy. I just want you to know how much I appreciate your AMAZING work; I love this channel as much as I love "Veritasium", "Smarter Every Day" or "Curious Droid" (which I think are some of the best science-related channels out there). I really wish you to get the number of subscribers you deserve -a million should be enough-. Keep up the good work!
Totally agree, Alessio! I'm from Germany, just accidentally came across this video today and I can't tell how much I appreciate it!

I so much wish to once meet all this science luminaries in real life, that's truly a big dream of mine!
@@annalemma5688 I already knew all of them (Scott Manley in primis), I just couldn't put them all on my list ahahahah! I'm really glad to acknowledge that I'm not the only one interested in such topics, it feels really good to see that other people are just as passionate about 'em as I am :)
You are a Truly inspiring person and we're lucky to have people like you in this world🌟🔭
I loved the the visualization you made there with emojis and signs, creative!
Fantastic idea and presentation! And thank you for sharing your thoughts. " Ideas and dreams relocated to the wasteland of lost ambitions". Well, that hit home.... as I'm sure it did others.
The ending is the best part to a brilliant presentation. It makes me want to go through older ideas of my own to see if any might have merit for pursuing today. That's quite an inspiration! Thank you.
26:51 "...Relegated to the wasteland of lost ambitions" sums up almost every project I've dreamed of starting. I'm hoping this will inspire me to take a chance and just force myself to spend some time building and finishing a DIY project. Nothing crazy like a terrascope lol, but it's a struggle to force myself.

I am a big fan of pop-science, and I have watched quite a bit of it on UA-cam, but this channel has managed to become my favourite.
You guys have a real talent for creating content that is the perfect blend of: easy too understand, interesting, novel, and educational. And of course the images of space are stunning as well. I really hope you guys continue to make a lot more of these.
David is the new Carl Sagan.
It's incredibly refreshing to see intellect and inquisition in place of the usual UA-cam nonsense. Please keep doing what you do..whether you know or not youre inspiring young minds to question and that's a beautiful endeavor.
This is a brilliant piece of science. I hope it works.
First and foremost this is truly inspired thinking and your explanation is genius. I will definitely be following your work on this and would definitely donate towards your work if you decide to crowd source. So I'm not a scientist just a fan. That being said I wonder if any type of configuration of mirrors positioned between or behind the telescope could increase the magnification or possibly decrease the size of the Terrascopes orbit? Or maybe lenses on both the poles? Your way smarter than me so you've probably already ruled these out. If you have I'm curious as to why. Keep up the good work.
P.S. LOVE LOVE LOVE the Halo Drive concept!!!!!
That's a great thought.
I don't know why, but your comment about going back to realistic goals and proven tech being "bollocks to that", hit hard.
Maybe because I too, am very curious about the cosmos and the endless void that we are in; And knowing that we can only see so far away and never beyond than limits of realistic goals and proven tech.
Whenever I look up at the night sky, I don't just see beautiful stars, but also in awe and dread of how vast and lonely it feels. The incomprehensibly vast and the unknown. I envy people who lived in the early days of astronomy, discovering new stuff and I envy the future generations that might leave our home to explore the galaxy.
Thank you so much Professor, the extra time and thought that goes into your prologues will mean more than you’ll ever know. No matter what field, study, or craft you devote yourself to, I’d like to offer another perspective. It was a regret for you not to pursue this project earlier in your life-but what’s to say that it wasn’t meant for you to set it aside until this moment. Seeing it from another angle, with clearer grasps on concepts, or perhaps entirely new perspectives. Whatever the case may be, your sentiment hits home-never give up on those ideas, dreams or ambitions. Even if they originated thirteen years ago, they may one day stand among your greatest achievements.
I hope to see this idea come to reality, i really like it. Also, your voice is very relaxing.
This sounds so crazy, it just might work!
Beautiful concept and beautiful video. The last bit about following your dreams was great. You are a good man, Prof. Kipping. And I do hope for a fleet of terrascopes, arescopes, jovoscopes, titanoscopes out there some day.
This was awesome.
Your words at the end of the video were great.
I've always been interested in physics but I'm currently going to college for mechanical engineering. You make me wanna switch majors to physics or come back and get it.
You're scaring me man. I'm in a combined program where I do physics stuff and then move on to mechanical but physics is getting me kinda hooked!
@@alexgehl8691 same dude. I'm my 4th year in engineering and I'm thinking of coming back to get a physics degree if not just switching entirely right now lol. Physics is so interesting.
Today I found an internet article on sciencemag about your idea....it spreads fast :))
This channel is the best! I’m literally going back to re do my maths and physics GCSE in the new year after watching your videos and hopefully go further. Happy new year Prof 🙌🏻
That’s amazing to hear, good luck!!
I love this idea so much more than any other since:
1. Not having a stupid scam Quick-starter plan to take money.
2. Admitting that there are flaws that we could find if we work on the project.
3. Great logical science that anyone who knows basic physics know.
I used to think of things like 'solar power roadways' was a good idea, but with a trail of thought it makes no sense. Instead of the solar telescope this could solidify the idea to then lead to such projects.
Great video!
Send this video to Elon Musk.
Edit: Glad to see other people had the same idea.
Okay
ROFL .... only if you can including a check with this video and don't mind everyone in the world attributing this idea to him ... be my guest.
It's the kind of stuff that NASA is responsible for...
Bandwidth is important, but true progress would be speed. Sadly, the Universe is a cruel mistress & will likely never allow for faster-than-light communications. Rather depressing to think that one may never be able to send a postcard home from Club Med Andromeda, boasting about the epic alien piña coladas & sexy topless alien girls frolicking on the beaches.
@@petrzalkai Funny thing is, he's getting the job done. His money, his mouth.
thought provoking concept and presentation - hope something comes from it. best of luck!
27:07 I understand my friend. It got to the point when every time I opened my mouth I would hear "another Pipe dream" and "you are having dilutions of grandeur" Great way to encourage a teenager!! Now I'm 46 and I never dared to dream. I wish I had failed, lost, and, died rather than lived this broken life I'm living.
Sounds like it has merit, very smart on using natural resources that has been given to us like planets.. I love it.
I like the wAy your 🧠 Works. My heart rate increased when you started talking about The Green Flash! 🤔
Thanks you for you message at the end. It really hit home.
The way you ended that segment, not waiting to start something now, after hearing your story....I am so inspired. Somehow equally making me feel like I am proud of you (even tho we have never met), and inspired by you. This was exactly what I need to hear. Not to mention the fact that Terrascoping is a truly interesting subject.
Thank you for being such an inspiration and reminding me just why I went back to studying ^_^ .. Not just to get a fancy job, but to get the chance to work with my own ideas again
Love the idea of the Terrascope! Looking forward to following this project as it moves forward.
But I also love the dream and passion (and caring) Dr. Kipping shared in the "Dreams of Our Youth" portion.
Most of those dreams are destined not to be fulfilled -- and indeed, as we get older, we likely realize many of them are better off that way. And yet...we are such stuff as dreams are made on. And dreams are such stuff as we are made on. In the arc of our life, the pursuit of our dreams may be more important than the achievement of them. We don't live four score and ten; we live now.
Awesome work and a beautiful closing statement which resonated deeply with me. Thank you! I'm sure that some day we'll see spectacular things thanks to your terrascope!
Damn, loved the whole video, but that last segment was totally worth it. Great video.
that's interesting. Just a couple of days ago I was playing around with the idea of using a black hole as a telescope, just as a thought experiment for fun. but your idea sounds more feasible.
Same here! It's pretty crazy how many people come up with similar ideas independently.
Brilliant, you did it again. :) I'm beginning to sense a pattern, what else could we accomplish using the astronomical objects at our disposal? You certainly got my mind racing, thank you for the much needed inspiration. I'm a programmer by trade, and I'm recognizing the traits of a skillful (scientific) hacker in the way you approach problems. I hope this idea comes to fruition, the images of interstellar objects we could acquire using this method would certainly be jaw-dropping. You mentioned the kind of image detail we could expect by using the sun as a gravitational lense, how would the terrascope compare to this in your opinion? Thank you for taking the time to explain your paper so clearly! Now I'm off to tackle my own project which I've put aside for way too long. ;)
Wow, fascinating video. Hearing about the whole process of inspiration that led you to the idea was a great touch; the terrascope concept was a very clever insight, and the way you concretized it in your research was very compelling and impressive.
I just want to add that I subscribed 10 mins into this video. Your channel is truly amazing, beats my local science festival / science week!
This was inspirational on so many fronts. Thank-you!
