Light speed questions

Question

just wondering, might be weird or stupid to u...idk. tell me where im wrong and where im right, if im even right lol. btw im 15 so be easy on me

the speed of light varies from its source. i based this off the big bang problem where all matter that exploded went faster than the speed of light. but nothing can go faster than the speed of light without time stopping. but you will say it was the start of time, but still the matter exist within the time. therefore it would be traveling backwards in time at the point of the beginning of time...idk. another reason is say you got the light from the sun, and the light from a supernova. the light from the supernova is faster than the light from the sun, saying that both are traveling the same distance and to the same object. so what is the source if time cant exist if its the same speed as light? wouldnt the source have to be infinite? isnt everything approaching the speed of light or at least trying? what if light is the source, and all other light we see is just weaker light approaching the source? what if everything in the universe is light? what if we are all just lesser light or a type of wave aproaching the main light? i know by now you think im nuts, so i will just say this to make it even nuttier...And God said, "Let there be light," and there was light.

Answer 1

No, the speed of light does not seem to vary.  The inflation of space itself does appear to have been faster than the speed of light early in the universe's history.  We really don't understand the mechanism that caused this.  And it's not the same as something traveling faster than light speed through space, which doesn't appear to happen ever.

That thing about space and time and the speed of light being a triangle is wrong, but the truth is something like that.  Space and time form a funny sort of triangle where the hypotenuse is the square root of time squared MINUS distance squared.  This hypotenuse, called an interval, is constant between two events for any observer in any frame.  Where the speed of light comes in is as a conversion factor between space and time.  To convert units of time into units of space, you need to multiply by c.

You are trying to apply your classical intuition (and what's worse, an intuition perverted by religious dogma) and apply it to situations where it just doesn't apply.  I won't say that science and faith are antithetical, but you need to keep your religious prejudices at bay if you want to practice science.

Answer 2

The idea about variable light speed as an alternative to the cosmic inflation theory to explain the horizon problem was proposed by John Moffat, and now championed by João Magueijo.

By all measurements, since man could measure it, the speed of light is the same for all observers, regardless of the motion of the observer, or the light source. The relationship between time, velocity, and the speed of light is given by the equation:

∆t' = ∆t / √(1-v²/c²)

This has been proven over and over, and is even factored into GPS satellites.

It might interest you to know that Georges Lemaître was a priest, professor of physics, and astronomer who proposed what became known as the Big Bang theory, which he called his "hypothesis of the primeval atom". He was a pioneer in applying general relativity to cosmology, suggesting a pre-cursor of Hubble's law in 1927, and published his primeval atom theory in Nature in 1931.

Your writing has a little to be desired, but I applaud you in thinking for yourself. Keep studying and learning. Who knows, maybe in 10 years or so your name will be up there with Galileo, Newton, Einstein, Dirac, Planck, Bohr, Feynman, and Hawking.
