No; no - it's a much milder effect than that in all the relevant ways. Basically we're going as fast as possible - light speed, straight in to the future, relative to nearby, stationary, objects. When you provide a velocity, you need to specify what observer is measuring it; that is something we see immediately from relativity.

Everything moves at the same speed, in a certain sense - "c", we call it. That seems counterintuitive, but it isn't, if along with the rotations you can picture there is another dimension in which one might steer - or rather, steer away from. We could take some of our speed through time and exchange it for some speed through space. This is time dilation. It is one piece more complex than that, as we are really talking about imaginary time, here. But "imaginary" in the complex plane sense. Flipping our perspective so that linear motion in one direction represents translation in complex time is called a Wick rotation.

You're thinking in terms of gravity, and I'm answering with geometry; but they are equivalent descriptions.

If you could sit somewhere near our observational horizon - say, 13 bly away, or somehow protected and hauling around a black hole, then we would appear to slow greatly - but also we would be very redshifted, and it would be very hard to get back. So practically you can kind of ignore it; but there is something there, if you really really want to run the world ahead into the future a little faster, and you are allergic to anesthetics.

You're absolutely right, basic theory of relativity. Time is a construct of humans. Does the universe know what time is?

Dont need to be sarcastic, just asking a question based on science. Nothing wrong with learning, its all we really have in the end

I wouldn't call it a great book... The book itself is mediocre, imho, but the idea behind it is very interesting, so yeah, it's still worth the read.

I believe time dilation is significant only under very extreme gravity. I can't really vouch for how accurate Interstellar would be.... I would tend to think that a planet near a black hole where time dilation is strong just couldn't be compatible with life and I cannot imagine it surviving as a planet.

It’s been a while since I saw the movie. I believe the one hour on the other planet created a +7 year earth time for the astronauts because an hour on that planet plus the trip home at near light speed was what caused the time. It’s a function that accounted for the delayed trip home and the travel at near light speed

Yeah that’s why I didn’t use that definition. Falcon Heavy is incredible but it’s not quite the same level presentation wise

Sure bud watever seems neato to you cuz thats all that really matters hail to you king of reddit and comprehender of time elsewhere !

Fascinating both for the story itself and the world building. Definitely worth a read.

Side question: what would communication or observation look like?

I mean, between two planets experiencing a big difference in relativistic effects like this. If you were to try to observe, or communicate with, a planet where time is moving much faster using EM waves how would this play out exactly?

Makes sense, i hope we find more answers soon! Very captivating stuff

I've always wondered what the experience of an individual was when falling into a black hole past the event horizon. From their/its perspective would it seem as if space was expanding infinitely away from them as they fall further into the singularity?

I don't know - they've been racing ahead with the installation of plumbing, buffer tanks, etc... they might be aiming to get it done in the the next month.

It's not like they ever work on only one thing at a time, and those panels are going to have to be able to come off reasonably easily anyway for maintenance and upgrades of the protected components.

IIRC it was Dr. Robert Forward.

To the observer us say a galaxy moving away at the speed of light time would stop for them as we view it because the light would no longer be able to reach us as they are traveling away just as fast as light. They out there on the other hand would kinda see the same thing of us time would stop as they are moving away to fast even though it would appear we are moving away to fast because everything is moving away from everything else all at the same time.

What about the fictional planet from interstellar, where 1 hour is 7 earth years on the planet? If thats possible, i see no reason to not believe that there are planets experiencing many years in the matter of a short time for us

Right so the sun is alive, got it

Another thing to note is the interstellar movie, where on the planet 1 hour is 7 years on earth. If a civilization lived on a planet like this but opposite, where 1 hour on earth is 7 years on their planet, or perhaps more, it could be very likely

A planet near the black hole would experience time much slower, not faster. Being in a gravity well slows down time relative to a point far away from it.

Absolutely!

In fact we already know this to be true. Our satellites experience time at a different rate than we do on earth and for that reason we must account for it when making calculations.

Your head and get agree differently too just due to their proximity to the earth.

Generally these things are so miniscule we will never be able to perceive them.

Perfect, who is the author? Their seems to be multiple books of the same title. Thank you
