Has the speed of light changed
WebJul 1, 2024 · If the speed of light has changed then this should show up as changes in the time of arrival of the pulsar emissions today. Edit: As Gordon Davidsson (below) points out, SN1987A is not a good test here. Suppose that when SN1987A exploded the speed of light was faster than now. Whatever that speed was, the light from the ring would still … WebThere's no way to change the speed of light without affecting the fundamental way that the electromagnetic force works, which in turn, would show up in all sorts of processes. That's not to say that something like this COULDN'T happen, just that the amount by which it …

Light just follows a curved path in the curvature of space-time produced by a massive object (a consequence of gravity). But, gravity itself doesn't slow down light. Because, we've just corrected these gravitational waves (a century ago) to not to be instantaneous, but travel exactly at c as a consequence of SR, which declares speed ...
WebTheir speed is defined relative to the medium. You could argue that the medium serves as an absolute frame. But light does not have this property. There is no absolute frame we can use. I want to know whether the fact that speed of light has to be constant is a consequence of other fundamental laws of Universe, or is it just a fundamental law ... WebAnswer (1 of 12): If the change is only a small proportion of the current value than we would not notice in everyday life. On the other hand a large change making it only a few times larger than the speeds of everyday objects would make us have to make reletavistic correct calculations. Our se...
