A MILLION MPH

How fast are you moving? Remarkably you are moving, by some definitions, around a million miles per hour. But, why don't we feel this motion? Is this speed useful in some way? And what does the question of speed really even mean? Join us today as Cool Worlds explores our motion through space. Written and presented by Prof David Kipping.

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

[@CoolWorldsLab]

@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.

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.

[@banehog]

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.

[@vill824]

@@banehog This calculation bit regularily represents a problem in the sci-fi series Star Trek.

[@sobo2]

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.

[@IroAppe]

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.

[@NoosaHeads]

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).

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.

I love astrophysics so much. This video is excellent.

Trace! I loved him on Seeker. That show just isn't the same without him.

If this video ends...I swear to God... EDIT: This video actually ended. I don't know what to do with my life now

[@southpakrules]

Wait for the next one

Well, you can always swear to God, right?

[@prototropo]

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 . . .

Dude, you just made me remember of Spaceship Earth. Thanks a lot! Stay safe there with your family! 🖖😊

[@JLK-cv1ze]

The problem with space ship Earth is that we are doomed to travel in the set direction 😕

@@JLK-cv1ze Sure, but I mean the TV program. You know? Yeah... I'm that old. 😕

Love this channel. Beautifully explained. I love the mystery of space!

Another brilliant piece of art to travel through the vastness of the internet and fill me and others with awe. :) I think there is a significance of having an "ultimate" frame of reference since it gives us an answer (in one way at least) of where our place in the universe is. Even if, like you explained, this doesn't matter we still have something to define our place with. Fascinating and thought provoking as ever! Thank you Dr. Kipping and team.

A million MPH is the speed my dog runs when I call him a dinner time ! I love my doggie and he loves me !!

"I guess the sun is almost ready to legally buy it's first beer." :D Loved this video so much it was an insta-subscribe. Although the speed references in MPH were a little confusing, and I'm an American! It's only because all the other science channels I watch use meters per second, so I found myself asking Siri to perform the conversions for me in some places. :P

[@curiouscrocodile3730]

What a BRILLIANT channel!! Thank you Professor, your presentations and explanations make it all so easy to follow and understand - we appreciate you.

[@ThePitt]

Amazing video. This channel is top notch.

[@jessetylerwade]

Always great content from you guys, thabks so much!

[@GeorgeStar]

It's great to have a science channel that explains science on a lay person's terms but doesn't patronize.
