What would be the effect if the speed of light was to suddenly double?
If the speed of light in a vacuum was doubled, what effects would that have on the universe?
Can we increase the speed of light in a vacuum? What is the speed of light in a vacuum dependent on? If the universe is expanding when will it exceed the speed of light? If the universe expanded from the big bang to the size of our galaxy in a micro-second, this must mean everything in creation traveled much much faster than the speed of light; how is this possible? What would happen if the speed of light was 0? Is the speed limit of the universe really the speed of light? Is it possible to move at 98% the speed of light, then have the entire universe move the other direction at 5% the speed of light? If you could travel the speed of light, what would happen? If the universe is expanding much faster than the speed of light, could that be a reason why we don't see much of the universe, only the "new events"? Will the speed of light ever change? Since the speed the universe is expanding is increasing what will happen when we reach the speed of light? Has the speed of light changed? Is light speed actually not the speed limit in the universe? What would happen if an object would reach the speed of light? Why is the speed of light so small relative to the size of the universe? Is expansion of universe faster than the speed of light? Assuming the Many Worlds theory is correct, is there a universe in which the speed of light is different than our own? How would that change things? How can the universe be expanding faster than the speed of light? Special Relativity: What would stop someone accelerating beyond the speed of light if they had achieved 99.9% of the speed of light? How much time would it take at an acceleration of 1G to attain the speed of light (disregard relativistic effects)? According to relativity, the speed of light is same for all observers but does it change when light changes the medium? If so, then would it affect the value of c and affect Einstein's equations? How can the far reaches of the unobservable universe be expanding at faster than the speed of light? We all knows that universe is expanding. Suppose that there are two different galaxies travelling in the opposite direction from each other at the speed of light. Can one will be able to see the other one ever? At what speed is the universe expanding? Is it faster or slower than the speed of light? Could the Big Bang have been a Big Vacuum? What is the speed of the universe with which it is expanding? What would happen if I travel with a speed of light? Is the universe expanding more than the speed of light? If yes then doesn't it break the cosmic limit? If the universe starts shrinking, would the time go backwards or would it just be the same? How was the speed of light ascertained?
