A theory long held as fact since the early 20th Century is that the speed of light is a constant as summed up in E=Mc2 (Otherwise known as Einsteinís theory of general relativity).
Now, however, a debate has started over the question of is that really true. If not, then Einsteinís theory gets tossed out the window.
If the speed of light was faster in antiquity than it is now, than the universe is MUCH younger than currently postulated since the age of the Universe is currently theorized based on the assumption that the speed of light was, is and always will be a constant.
Question #5 Can you prove empirically that the speed of light has remained constant since the beginning of time?
