Speed of Light

A comment I left on Ray's Post: The age of the universe

Someone asked him, "Dear Ray I have a question for you, considering God made the world and the universe in six days and considering He created Adam in about 4004 BC why is it that scientists say that the most distant planets are over 20,000 light years away. This means that the light from these planets has been traveling in space for 20,000 years, far longer than the universe has existed even if you count a day of creation as a 1000 years?"

My reply was, "Everyone needs to keep in mind that 20,000 light years away is a measurement of distance NOT time. I just thought I would point that out before I start reading all these comments. You are taking great assumptions thinking that light can travel at one speed.

In a lab setting they even slowed and stopped the speed of light. (Google: Bring Light to a Stop)

I remember that Carl Sagan explained in Cosmos that if a spaceship traveled at the speed of light when he returned back to earth after 5 years many hundreds of years (Corrected to: Mere minutes turned into many decades) would have passed on earth. Everyone that space traveler knew would be long gone. So if speed of light indeed effects time then one can see, quite simply, that the appearance of millions of years is actually a short time at the speed of light.

BTW you all do understand what God is right?...1 John 1:5

In Cosmos maybe Carl Sagan was talking about 2 Peter 3:8.

UPDATE: Is there a fellow geek/nerd out there that can tell me, in reference to Lorentz transformation (Lorentz factor), how to calculate the difference between (x) earth time and (y) speed of light time?

For example 1 minute of (X) equals, let's say 30 years of (Y)...and does it grow linearly, any takers? I just read "If space is homogeneous, then the Lorentz transformation must be a linear transformation."

Great I found the formula. Now I have to figure how to enter this into my HP 32SII calculator

Now I just read "Indeed, a constant 1 g acceleration would permit humans to travel as far as light has been able to travel since the big bang (some 13.7 billion light years) in one human lifetime"

That is if light can be accelerated, which is the case as in black holes right? (People, like Einstein, believe that light cannot be accelerated. They jury may still be out.)If light can be slowed and even accelerated, as in black holes, then it could be seen that light could reach a point at a perceived length of time which relative to reality of (y), the spaceship, took a very short time.

UPDATE 2: I concede that explaining about God in this manner does a real injustice to the Gospel. Not to mention how extremely unbiblical it is.

Also someone recommended a book called "Starlight, Time and the New Physics" by professor John Hartnett. Building on the work of secular cosmologist Moshe Carmeli, Dr. Hartnett's book explains how we can see distant starlight in a young universe while at the same time doing away with the big bang 'fudge' factors of dark energy and dark matter. I might want to get a copy of that one.
