Futher back is faster expansion?

02/25/2009 7:14 PM

Scientists say the the acceleration of the universe is increasing.The further away an object is, the faster it is moving away from us.Ok, Ill buy that,but the further away, the farther back in time that object is, which to me says the the universe was expanding faster when it was younger.How do they resolve this fact to arrive at their conclusion of a presently accelerating universe?We have no idea exactly where the galaxies that we see are right now,only where they were billions of years ago. Curious.

Yes,

That does seem to be backwards somehow. It kinda reminds me of something I heard on the 'Amos 'n Andy' show years and years ago.

"Nobody nevah splained it to me dat way befo".

If we can see equally distant in all directions,a sphere of sorts, and we are not the center of the universe, then we cannot see the furthest limits of the real universe, and never will.We are limited by the speed of light as to the maximum distance we can observe.And so is every other observer in the universe.If the universe truly is accelerating it's expansion rate, at some point it is , or will be at or exceeding the speed of light.Galaxies will redshift into invisible oblivion, as I am sure some probably already have. Now just suppose that space time itself has an effect on light frequency, and the effect, on a quantum level, is not noticeable in sub-light year distances. The further light traveled, the redder it would appear.In effect,space time could have a very slight "red" tint to it.This could be misinterpreted as acceleration. ShoeShineBoy
