You have a spacecraft that moves relative our universe very near to the speed of light.Let us say that you set up two light-bulbs, one in the nose and one at the ships 'tail/end'.You yourself are placed inside the middle of the ship observing them both (free line of sight)My question(s) is:)light-bulb = oyou = x -------ship------- ---> 'o' 'x' 'o' ---> ------------------A. Will the frequency's from those light-bulbs differ?
Time and gravity goes together
So you see it as connected to acceleration only.What would then differ that from its final motion?What energy transfer would acceleration give (and deduct) the light that a final very high uniform velocity wouldn't? -------Would it be that under acceleration its (the spaceships) frame never would be at rest?But when 'cruising' the frame always keep its uniformity.Reasonable?------------Awh, it sounds good, but it doesn't explain why the energy would differ, does it:)
QuoteTime and gravity goes togetherHmm... only in the sense that time and space go together, and where gravity is regarded as a change in space-time.While the idea of everything existing in it's own time-frame is widely known from the traveling clocks experiment, if you go along with the idea that space and time cannot be separated and can only properly be treated as a single spacetime concept, then it would seem that everything also exists within it's own space-frame. More correctly, everything exists in it's own spacetime-frame and movement, which is what you're talking about here, is the product of space and time.
Thanks Lightarrow.Looks like I'm missing something to simple to see:)To me red/blueshift seems to have more to do with creating a 'gravity well' behind the tail of the ship when accelerating?
