You're welcome man 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. "Pretty much all 14 of the CSM were in favor of a drone assign nerf for OBVIOUS gameplay reasons" - Sala Cameron
James Amril-Kesh 4S Corporation Goonswarm Federation 9618	Posted - 2014.05.08 19:34:00 - [4] - Quote 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.

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 :) http://www.reddit.com/r/explainlikeimfive/comments/22pi7o/eli5_why_does_light_travel/ 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). That actually clarified things significantly for me as well. "Pretty much all 14 of the CSM were in favor of a drone assign nerf for OBVIOUS gameplay reasons" - Sala Cameron
James Amril-Kesh 4S Corporation Goonswarm Federation 9631	Posted - 2014.05.08 21:16:00 - [6] - Quote 1 AU is about 8.32 light minutes (.32 minutes ~= 19 seconds). As said earlier, light doesn't travel slower in a medium, what happens is that it's absorbed (photon energy excites a valence electron in the material) and re-emitted some time later (excited electron releases its energy in the form of a photon to return to the base energy state). And again, light doesn't actually bend. Light always travels in a straight path. The space that the light is traveling through is curved.

Mr Epeen Assuming 2,500,000 LY exactly: A Nomad (most fuel efficient freighter) at JDC 5 has to make 222,223 jumps, consuming about 1,687,500,000 hydrogen isotopes at JFC 5 and JF 5. You'd need a little over 1/4 of a cubic kilometer of fuel (250,000,000 m3). An interesting exercise would be to see how many jump freighters full of fuel you'd need to get one jump freighter all the way across, but I don't feel like doing that math right now (and I'm not entirely sure how I'd set up that problem).
