Thank you Einstein and DKV:

If I told you there were 200 tombs in Egypt?s Valley of the Kings you might reasonably ask me how I derived that result. Many things in science have fixed results derived by mathematics, physics or even common sense.

How did we arrive at a speed of light at 186,281 miles a second? What is there about our Sun light that musters out instantaneously at that speed and never changes? What happens to that blast off that inhibits the speed to stay forever the same and why do we think that this scenario is logical?

I think this question is on topic with the posting. Whose going to give us an answer?
