Although there have been multiple responses here made with seeming certainty, the answer is that this is a wide open question, the answer to which is currently not knowable. There is nothing but speculation, as we here on earth do not have a large enough context from which to answer this question. Based on the highly limited context that we do have from earth, the answer seems to be that the speed of light is absolute. However, it is very possible that this is not the case.

Light can be slowed down by the materials it has to pass through, but for the same material (or no material) it is a constant. Anyway there is a theory involving a very slow deceleration of the speed of light since the birth of the universe, but this would cause creation of energy, and at the moment we don't have proof of any violations of the thermodynamics laws

Yes, no matter how you're moving you'll always measure the speed of light in a vacuum as the same. However, light slows down when it goes thru substances like glass, air, water.

Yours is a assertion of the "twin Paradox." even if it is not a paradox. The frames of reference for each twin are no longer equivalent. in basic terms one physique (Alvin) gets sped up, as a effect we are able to tell the variety between the two frames. in basic terms the physique it somewhat is sped up has time dilation. evaluate: the two Albert and Alvin start up interior the comparable physique of Reference. they're in windowless area ships. The rocket for each deliver is carefully vibration-much less. The rocket of in basic terms one deliver is going to fireside. What test can Albert and Alvin do to be sure in the event that they're the single being sped up? They each have a a million kg mass and a pair of meters of string. (Or a million kg mass and a spring scale) If we anticipate it replace into Alvin, what does Alvin see that Albert would not see?

Yes. I assume you mean "speed". No matter where you measure it, and no matter how fast you're going, the speed of light in a vacuum is always the same.

Peed of light? What's that? Is it near Uranus?
