Universal Constants and BBT

I dug up this old news snippet for info though I watched something about this on tv science programme.

When the universe was very young, the the laws that governed it may of been different. It is suggested that since the Big Bang light has slowed down. How can we tell by looking back with telescopes to measure the universal age and expansion using only constants that we know of today? If light speed was faster than maybe the earliest galaxies would be further away than we believe today and what implications does this have for the doppler shift we see from distant early stars? Would photon properties alter after billions of years of travelling which could affect results?

Was Einstein wrong?

ICR ditched c-decay (which requires altering two other constants, for that matter) a good fifteen years ago.

Apologies for posting the link http://www.talkorigins.org/faqs/c-decay.html but I can't explain it well enough myself. :\

I don't think this was a creationist arguement but something to do with the universe expanding faster than light could of possibly travelled probably during the period of inflation. And I heard this talked about more recently than fifteen years ago. Good webby link.

In the second to last section of the third link you posted it says:
"The studies do not support the idea that the speed of light was exponentially faster in the past."

 

[webboffin]

Arikay, I am not supporting the theory or denying it, but really finding out what it is all about. The links I gave are for reading up what I don't know.

 

[Arikay]

Ah, ic.

Ive been reading up on it too, I havnt gotten to the talk origins article yet.

 

[webboffin]

It's okay Arikay it is unusual for me to just ask about stuff, lol

Would light speed need to alter for the massive cosmic inflation? Maybe there is no link to light speed and inflation. But then I think what affect would this have on space/time as space would expand very rapidly?

Found another website: Inflation for beginners.

Another website suggested the speed of the universe inflating was 100 times that of the speed of light.
