Re: Time (some weird ass physics, man)

I usually here the phrase when someone's talking about the perception of time. During times of high emotion (trauma, joy, etc) time feels slower because of adrenaline and what else have you.

Time slows down as you approach speed of light though, regardless of perception.

All right, so assume time is a physical thing that travels at a fixed speed.

You are now going faster than it.

But the point is: how can time have speed if speed is distance per time?

I wasn't sure if you were talking about only the physics aspect, or if it were the phrasing that was confusing.

My physics-fu isn't good enough for time dilation, unfortunately.

For the ELI5 version of time dilation (which I have not seen in a SF book in forever), it's like this: faster-than-light space travel is, according to the currently-known laws of physics, not possible. However. SF authors get around this by having their ships fly almost at the speed of light. Remember this.

OK. So you know how astronomy/science shows on TV say that the stars we are looking up at are not "real-time"? What they mean is, when you look up at a part of the night sky from Earth, it may have taken millions of years for the light from one of those galaxies to reach your eyeball, at that very moment. Closer to home, the light we see from the sun in the sky isn't "real-time" either, it's eight minutes old.

So. Travel to a distant galaxy at almost-the-speed-of-light would still take a long time (generation ships are proposed as the answer to this). Hopping around to various stars in our own Solar system might be doable. However. thanks to the time dilation effect, the closer the ship gets to almost the speed of light, the further away they get from earth...and the longer the light takes to "reach back" to earth. So our ship could travel for ten years at almost the speed of light, but that light is still going to take thirty years to reach the earth, due to the distances covered, resulting in a round trip making the occupants of the ship twenty years older, but the residents of earth sixty years older, when they all meet up again.

*our own galaxy, not our own Solar system duh

No, I get the concept well enough. I'm just not good enough to explain it to someone else, especially if they spring questions on me. Thank you, though. :)
