The speed of light appears to be constant now, was it always? Maybe NOT. In the first few moments of the big bang the speed of light was more likely 50-60 times its now known speed. This is known as VSL (variable speed of light). This theory is still in the works, but more eggheads are looking into it. ~A~

Yes, but the speed of the universe has not. If It had fluctuated (speed of light) physics would have to be rewritten. C is always a constant, and will always be a constant in a vacuum. However it is distorted around strong Gravitational fields, black holes or gravity waves.

I know there has been a debate going on about change in physical constants over billions of years. It's high-end stuff though and has something to do with expansion of the universe. but in a million year or so the constants remain constant including C. I think Edward Teller, father of H-Bomb, first brought it up in 48, but I am not sure.

The speed of light in vacuum is exactly equal to 299,792,458 metres per second and it is defined as a constant. Therefore, it is not allowed to change! However, speaking hypothetically, if it were to change, the second would change accordingly to keep the speed of light constant.

Yes always constant, but it according to the power.
For example: If a sparkle in small wire it will appear for distance of 20 to 30 feets,
If its a blast means it will reach 200 to 300 feets,.
But if it is a thunder means??? u know very well.
The light speed is constant, but we have measure based on the force
Hope you are clear

A very good book by Stan Deyo (forgot the title) broached this subject. He believes that light speed has changed, and he uses this to explain the "old earth" theory.
Google 'Stan Deyo' he has a web page.

Amazing, always contradicting answers in science. no truth, no help, no satisfaction, a constant struggle to catch butterflies and the end of ALL rainbows

"Always" is a long time.
Another good question would be "Is gravity a constant?."
At the speed of light, for a given body (let's say a photon), time is nonexistent, by my understanding of relativity.

relatively easy travels at consistent velocity in each and every medium. finding on the medium, the value won't be the comparable velocity because it travels interior the vacuum, in spite of the shown fact that it quite is continuous in each and every medium. to illustrate easy is going in vacuum, it is going to trip at consistent velocity and if it strikes right into a close by crammed with air, it is going to nonetheless trip at consistent velocity, however the value in air and in vacuum might have diverse magnitudes. there will be a velocity exchange momentarily, yet besides that it will consistently trip with consistent velocity at diverse importance.

Bamma say he a closet scientist. Bamma say speed of light faster at edge of universe. Bamma say nobody measure it yet there. Bamma idol Einstein. Bamma study all his notes. Bamma even have same hair. Bamma say outter edge of universe have less dark matter to slow light down. Bamma say bigger the universe the faster the light. Bamma otta know.
