What if the speed of light is not a constant?

Over the age of the universe, it, like other universal constants, *may* have actually changed. There were/are? some astrophysicists who believe this to be possible. The important thing about the speed of light, however, is that it is believed to be the *universal speed limit*. i.e., light can travel slower than light speed when it passes through various materials.

Even the effects of gravity are limited to and travel at light speed. The Sun is about 8 light minutes away. And so if the Sun were to suddenly disappear, Earth wouldn't feel the gravitational effects for about 8 minutes.
