ological aging get sped up too? I watch enough space/science YouTube to keep hearing about how time works differently when you’re traveling really fast in space or really far or something and each time I try to have to explained to me, it never connects. And I’ve watched a few popular YouTube videos explaining how it works but it still makes 0 sense to me. I trust GBS goons will be able to help me out and explain why a person in a rocket going really fast apparently ages faster/slower compared to the people on earth. Also is it possible to have someone go fast enough that they age slow enough to time warp into the future and only be a month older and the world 100 years in the future?

If someone had a really powerful and precise telescope that could follow your spaceship and look through the window as you zipped across the sky at close to the speed of light - to the person looking through the telescope you start to look like you're moving/aging/living in slow motion. From your perspective, if you could look out the window and see what people are doing in cities and whatnot, everyone else seems to be moving normally.

The person going fast will appear to age slower to people who are not traveling that fast. To the person going fast it will appear they are aging at the same rate they always do.

buglord posted:Wait slower for who? The rest of us or the person going fast? The person going fast. When you see the sun, you’re seeing it as it was 8 minutes ago because it takes that long for the photons to reach your eyes. Photons don’t really age because they are moving at the universe’s maximum speed limit. Picture a tiny man riding on a photon from the sun; by the time he arrives at your eyes you’ve aged 8 minutes during his journey while he essentially is exactly the same age as he was when he left.

The important part of the statement is "THAN". Faster or slower than a chosen second frame of reference/point of view. For you, nothing seems "faster" or "slower" with anything that is moving along with you (your spaceship, your brain/thoughts, the poop in your butt). It's about how light is always measured to travel at the speed of light to ALL observers regardless of their own motion. Another way to interpret the math is to say that it's about differences in acceleration rather than velocities, if I'm remembering things correctly, but it's been a while since school. If you want a pretty thorough and step-by-step walkthrough of the math/principles, this guy's vid (https://www.youtube.com/watch?v=KZ8G4VKoSpQ) is not bad. Some of it is feels like a narrated a wikipedia article, but seeing each step built up and the background of the then-accepted science plus it's paradoxes and problems can be very helpful for most people. If that fails, it will still be great as a sleep aid. e: PBS' SpaceTime has some less mathy explainations and prettier graphs+graphics, but there isn't really a single video that explains everything, so it's hard to recommend a starting point. Maybe the first half of this one? https://www.youtube.com/watch?v=6MfJ59lkABY Roumba fucked around with this message at 04:40 on Feb 9, 2023 |

Here's an interesting one: due to the expansion of space you can go faster than the speed of light away from things but not faster than the speed of light towards things!

It's all relative, OP. There's no such thing as an isolated "fast". You can only move fast in relation to something else.

Space and time are the same thing, so the faster you move through one the slower you move through the other since they add up to moving through the same total this is correct

Light photons do not experience time. The universe begins and ends in an instant for a light photon. Relative to you, time speeds up when you go fast, so when you hit the speed of light, the universe ends. That's why it's not possible to go faster than light speed. I believe the other type of thing like this is entering a black hole. If you could somehow withstand the force of gravity to survive, the universe would end from your perspective as you entered it, and from the universe's perspective, you would appear to freeze in time right as you entered.

Time is different relative to outside observers but you will age the same relative to yourself. e.g. if you were traveling really fast in space for 10 years then you would age 10 years but people on earth might have aged 50 years. e: this time dilation effect also happens with gravity like in Interstellar. The closer you are to the source of gravity, the slower time moves. So even on Earth if you and another person are born at the same time and then they live on a mountain while you live near the sea then you will be different ages as time passes.

the speed of light of constant, not relative. so the closer to that speed you get, the slower you experience time relative to observers moving slower than you. from your perspective, everything is normal. from the observer's perspective, everything is normal. the clock on the ISS moves fractionally slower than clocks on earth because the ISS is moving fractionally closer to C than we are.

also any time a physics concept references "the observer" it means "the measurer". the only way to measure stuff is to interact with it in some way (by bouncing photons off it, for example). there's nothing magical about consciously "observing" something AS MANY SCI FI BOOKS MISUNDERSTAND GODAMMIT

Bula Vinaka posted:Light photons do not experience time. The universe begins and ends in an instant for a light photon. This most succinctly describes the two ways relative time dilation affects time in layman's terms. So basipally as relative velocity/gravitational force increases on an object say a space ship, local time (and everything it affects like aging) slows down in relation to something that isn't the space ship, like an observatory. Relative velocity and gravity causing time dilation is even measurable between Earth and the ISS. The astronauts age microseconds slower than the people on earth because they're going orbital velocity while simultaneously aging faster due to Earth exerting less gravitational force on them. https://en.wikipedia.org/wiki/Time_dilation Nyan Bread fucked around with this message at 06:31 on Feb 9, 2023 |
