Thanks for watching everyone! As proof of that physicists like myself don't usually work in mph, we actually screwed up a number at 13:34 - the circumference of the Earth's orbit is 0.58 billion miles *not 1.5 trillion*. The speed stated is correct though, I think this is the only error!
A photon arrives at a hotel reception, and is asked by the receptionist, “do you have any luggage?”, to which the photon replies,”No, I’m travelling light.”
I don’t get it, You can still have luggage when travelling light. Travelling light usually indicates just one bag, which would mean he did have luggage.
I can’t tell you how happy I am to have found your channel. I watch all your videos in the day to learn, and at night to fall asleep to. I love both learning about the universe, as well as getting lost in it.

Your knowledge and delivery is first class. So glad I came across this channel . its quite humbling to realise how much you don't know when listening to Professor Kipping
Love everything about this channel! The voice of the narrator, the perfect balance between simple and complex explanations and details, the music, and so on. Amazing work, this channel should have few millions subscribers.
Watching these videos always reminds me that whatever problems or disagreements we may have here on Earth are inconsequential to the sheer size and greatness of space, and the time it's amassed. It's truly humbling.
This is why the idea of teleportation always bugged me. It seemed like, wherever on Earth you WANTED to end up, you'd always end up at a fixed, motionless point in space, watching the Earth race away from you as your eyes boiled. Cool power, bro.
I think you may be confusing two different concepts here. If you move *instantly* between two points in space (by some magic), there is obviously not an issue - that point will not have moved relative to where you left from, since no time has passed. If you disappear from one location first, then reappear somewhere else a moment later (using some kind of disassemble/reassemble technology), you would just calculate where the point you want to teleport to will be in say 5 seconds (not where it was when you left). Now the concept that *should* be bugging you in this regard is *time travel* - if you time-jumped say 1000 years back or forward in time, the earth would be nowhere near where it was in the time you left, and you would die in cold space instantly.
I think teleportation - if it were possible - would not only transport you from one point to another, but also change your velocity so it matches that of the destination. Imagine you teleport from somewhere in Germany to somewhere in Australia, say to Sydney. These are two places on the opposite side of the Earth. And due to the Earth rotating, Germany is heading in one direction while Australia is heading in the other. If your teleportation mechanism would not accommodate for the velocity difference - that is, for the different speeds and different directions of movements - you would show up in Sydney rushing through the air much faster than a bullet. If I'm right, at a speed of 9000 m/s, which is 27. Besides, teleportation should also adapt your orientation, or you'd show up in Sydney upside-down. And moreover, teleportation would resemble faster than speed-of-light movements, and that would cause time paradoxes. The video "Why Going Faster-Than-Light Leads to Time Paradoxes" explains this. Therefore i consider teleportation as impossible.
If teleportation is dissolving you at one point, and reassembling you at another point, that teleportation device at the destination already has the right velocity at which it assembles your particles. That's why, if teleportation works like that, that's not a problem. Now, the Star Trek assembly not on a teleportation pad, but freely on a planet, that's a question how we could assemble particles so far away from every device. But then yes, I think, if we are that far, we can calculate the right velocity so that it is ok.
If you were teleported, you'd have to be first disassembled into some kind of a sub microscopic particle or waveform. If chopping your head off would kill you, then disassembling you into quarks or strings would kill you even "better" ie teleportation would *always* result in your death. The facsimile recreated might have your thoughts and memories but you would be 100% brown bread. My advice is that if you ever invent a teleport machine, get someone else to try it out. (And maybe stick a fly in the machine, as well as the person. - Should be good for a laugh).

This is an excellent video in terms of content and its production. Also, you have great talent narrating the information: cogent views and engaging delivery. Well done!!
It is more intuitive, even for those that work in KM/h. The average human (including myself) can not scale down both kilometers to meters AND hours to seconds quickly and intuitively. I’d prefer he used KM/h, but MPH is better than M/s
@Conner McKinnon Right, it's pretty rare you meet someone who talks about the speed of their car in meters per second. My only claim is that MPH is more intuitive than M/S (to most), not necessarily it is the most intuitive as that varies depending on where you live.
@@CoolWorldsLab exactly. I can understand MPH much easier than M/s. Especially when the values are going to reach into the millions of MPH - which is already difficult enough to comprehend 😂🤣😂

Thank you for another beautiful video. I would like more on "frame of reference" and relativity. How come spin stability works - what do we spin relative to? Is there really no significance to the cosmic background radiation "wind"? Does space have properties that make movement and speed transfer bodies between zones of space influence? Could we even tell? Physics is a real honeypot for my attention... and your shows are just the best.

You’re videos make me drift off into the night thinking about travelling from earth all the way to the end of observable universe. I’ve thought travelling space ever since I was a child. Hopefully one day humanity has the ability to travel through space and see what is really out there, our beautiful universe. Thank you professor.

And if the answer to the fermi paradox is "unique life", then the responsibility to spread life throughout the barren universe weighs heavy upon mankind. A far greater "divine destiny" than any preacher could have ever imagined.

Stay thoughtful and stay curious. A beautiful way to round off a clear cut educational video.
These videos never fail to amaze me with all of your knowledge and you give such a broad Perspective of our universe and I’ve never been more interested in anything than I am right now about this Chanel just wish there were more vids! Keep it up
Orbital Mechanics is one of the most mind-blowing concepts for me
This channel is the only reason I disabled ad block on YT. Such amazing content, and it's all for free, least I can do is giving him the ad revenue
That really made my day I needed that🤙🤯
Best TH-cam channel ever✅🔥💯🥇
Brilliant and sobering! Stunned by your work and how you manage to make every video so riveting!🤓 please Kipping, carry on by all means!💚

Father of the vaccine!!!

@@reidflemingworldstoughestm1394 If I can't comprehend it then stop yelling at me for underestimating it! If you want me to know how fast you are so badly then just fucking tell me. GOD.
I’ve always been curious about this exact topic. And you’ve explained it so eloquently. Keep up the good work, this channel is gold 🙌🏼
Me too !
I cannot help but echo my usual comment to your videos: you are the best, professor! 🙏
I reached my level of comprehension for one night. I subscribed, and will watch again tomorrow. To fully grasp all this in a practical way might take me a year. This is a fantastic video. Thank you.
You’re videos make me drift off into the night thinking about travelling from earth all the way to the end of observable universe. I’ve thought travelling space ever since I was a child. Hopefully one day humanity has the ability to travel through space and see what is really out there, our beautiful universe. Thank you professor.
Pleased to have found this channel. A joy to hear such clear, crisp narration and the background music kept suitably low (such a problem for us with hearing difficulties).
Love space. Thank you for the education :)
17:20 - Love the fact that you've compared it to a DNA double helix, that's exactly what I was thinking :D
I’m shocked I haven’t found your channel sooner. It’s quickly become my favorite space channel on YT.
No one is coming to save us from ourselves, it’s up to us to care for our spaceship earth.
And if the answer to the fermi paradox is "unique life", then the responsibility to spread life throughout the barren universe weighs heavy upon mankind. A far greater "divine destiny" than any preacher could have ever imagined.

Relative velocity is like vehicle insurance, “never admit fault, the other object hit YOU, you didn’t hit it.
If this video ends...I swear to God...
EDIT: This video actually ended. I don't know what to do with my life now
Wait for the next one
Well, you can always swear to God, right?
Ditto! I get so excited when a new Cool Worlds is released, and feel molecularly deflated as we approach atmosphere re-entry.
Neither Twin Peaks, nor Star Trek, nor Twilight Zone held me in such thrall.
Mary Hartman . . . possibly . . .
Get a life maybe
@@sonarbuge7958 The rest of us are here because we do have lives.
this man has the most elegant narrative voices on youtube
Omg I've missed you guys !!! Greatest science channel on TH-cam !!! Rivals Brian Cox in pure passion of physics in my opinion.
Thank you for all your work. It's so beautiful and intuitive, not only in terms of science and physics but all so in terms of philosophy and life.
"In many ways, the answer doesn't really matter... It's the relationship between things that matters."
This is one of the science breaking news source on planetary movements an the hunt for exo moons. This will be the ONE channel on TH-cam that will be the most rewarding when more exo moons are found. Bravo on this most fascinating source of Exo Moon Exploration.
I think the Webb telescope next year might be able to detect them
Thank you for opening our minds. Great presentations. Your students are so blessed. All intrigued viewers are blessed too. 🇨🇦
I love astrophysics so much. This video is excellent.
I listen to these videos while at work and absolutely love it he has a very comical voice but the information is mine blowing and inspiring!
Another brilliant video, Professor. Love the Interstellar soundtrack interspersed throughout.
This is the best video I have ever seen concerning this subject. It’s a fascinating topic. Thank you for once again educating us, Dr. Kipping!
There are at least 7 definitions of a mile. The imperial units are far from simple and very unnatural these days.
12 inches is 1 foot 3 feet is 1 yard 1000 yards is 1 mile never heard of anything different
The unit of 1 foot was first used and measured by the Romans it literally was the length of the roman foot soldiers boot
@@markmitchell450 it’s actually 1760 yards in a mile. The metric system is much more intuitive. 1000 millimeters = 1 meter, 1000 Meters = kilometer. It’s all the same numbers and not some random amount of yards.
@@markmitchell450 well you’ve not researched it well.
One mile = 10 miles in Sweden, don’t ask me why
@@darrenjones9359 but that is a mil not a mile
@@stridenbear same route smartarse.
Wow.. You deserve millions of subscriptions and views. This channel deserve so much more than this. Keep up the excellent work! Thank you so much for the great content!
Here watching from Uganda !. And you mentioned Kampala 😊
I was actually very tempted to fly there for this video….
@@CoolWorldsLab huh. Please 🙏 make sure you come !. I will be glad to host you 😊🥳🥳🥳
Bro I used to live there for a year, I went to Kampala international school lol
@@lukekirby9123 wow small world . You should come back 😊. Where are you apparently ?
@@mandyronald8187 I'm from the UK lol but I lived there for a year when I was 14, it was an experience of a lifetime, I never knew lake Victoria was that green! I'll probably never have the chance to go back tho 😭
I am so happy to find you and learn so much. Thank you so much!! As others have said, I can literally listen to you day and night!!
It is very exciting to hear other videos and scientists talk about professor K's papers and even just mention his thoughts. I'm quite sure all those involved with Cool Worlds hear these type of things all the time. Us old dumb guys who don't understand 90% of the things bring said in the videos. Yet the 10% we do think we understand have made this channel our favorite. Love hearing our favorite physics rock star being quoted.
That is one very old globe you used there!
I really enjoy your videos. Your presentation of information is easy to listen to and comprehend.
Sublime and succinct, truly in awe.
You are such an inspiration!! The way you teach, your video and especially you..... you just made me wanna learn more about it.... thank you 🙏
