Uh huh. And this is a sensible, non-idiotic question that cant be looked up in seconds, quineg?

Irrelevant - it still makes it clear that he's asking for in-game info.

Youre dumber than the average dumb eve player.
Only you, at least, don't try to hide it.

I like you.

Use a jump planner to figure out the distance between low/null systems.

Forget lightyears. How fast is a parsec and which way is Kessel?

I can't believe Tesla asked this question. This has to be a troll thread.

Actually it would make more sence to use Parsec in New Eden as it is not cohereant to use the Julian Year.

Give or take gravitional distortion and the observer's perception based on the point and condition inherent in that observation.

What? Light travels the same speed in all reference frames.

depends on the medium it is traveling through (light in water is considerably slower than in air and that is again slower than in a vacuum, it's the principle refraction is based on), though gravitic lensing primarily changes the direction photos are travelling in, not their speed so much, though the visual effect is quite similar to refraction.

Medium is independent of reference frame. If light is traveling through water it'll still be traveling through water if I look at it standing on the shore or in a spaceship in orbit. And it'll be traveling at the same speed from both perspectives.

Gravitational lensing doesn't actually change the path of light - the light is merely following the straightest path through curved space-time, so it appears to bend because of the local curvature of space.

This is inaccurate.

Light always travels at the same speed.

When light travels through a medium,
it spends time interacting with "stuff", (atoms absorbing and re-emitting)
which makes it appear to be slower,
while it actually isn't.

Yeah, this is also correct. Thank you for adding that.

Oh ok. Sorry.

I thought that the passage of time appeared to be altered the closer to the speed of light you reached, therefore the length of time to travel the sdistance would vary depending if you were the subject or the object.

I really am trying to remember this stuff from school, so Ill take your word for it :)

The only real difference as far as light is concerned has to do with its wavelength. If you're traveling at a very high speed towards a light source, the light you receive will have a shorter wavelength (higher frequency), and if you're traveling at a very high speed away from a light source, the light you receive has a longer wavelength (lower frequency). Blueshift and redshift, respectively.

Light coming from deeper in a gravitational well will also be redshifted, and light coming towards you from further out from the gravitational well will be blueshifted.

This might be interesting for you.

It's not for those who believe they can read things and understand it immediately.


Great read.


A relevant part regarding time dilation:
Quote:
By the way, this is why time dilation happens: something that's moving very fast relative to you is moving through space, but since they can only travel through spacetime at c, they have to be moving more slowly through time to compensate (from your point of view).
