Olber’s Paradox
Part I – A Cat-and-Dog Fight
Maybe my “Location” hints at the answer?
Two members have been discussing here Olber’s Paradox, without ever naming it. It’s just another one of those things that Big Bangers claim is
yet more proof. They’re making it necessary for someone to go into this at great length, so it’s their fault if I have to fill up even more
space. Fortunately it’s infinite, no matter what they keep saying....
On page 1 “trace_the_truth” starts it going, thus:
“If there is an infinite amount of matter then there is also an infinite amount of stars. If the infinite stars have had infinite time for their
photons to travel omni directionally across the infinite universe then every line of sight from anywhere would end on a star.
“Space wouldn't be black. It would be white.”
Then on page 2 “Watcher-In-The-Shadows” takes up the challenge and says, “Light gets dimmer as it travels.”
“t. the t.” then drags poor Poe into the matter:
“(...) if there are an infinite sources of light in an infinite area, then with infinite time, every where you look will end in light. It is very
simple.
(...)
“As Edgar Allen Poe has said on the subject:
‘Were the succession of stars endless, then the background of the sky would present us a uniform luminosity, like that displayed by the Galaxy,
since there could be absolutely no point, in all that background, at which would not exist a star. The only mode, therefore, in which, under such a
state of affairs, we could comprehend the voids which our telescopes find in innumerable directions, would be by supposing the distance of the
invisible background so immense that no ray from it has yet been able to reach us at all.’
“... and of course, he illustrates a universe so large (perhaps infinite in size) which can't possibly be infinite in time. This is compatible with
the big bang theory due to the expansionary period and the speed of light.
“You say light gets dimmer as it travels. That is of no concern to an infinite universe with infinite stars and infinite time because the photons
are spreading out over an infinite area infinitely. In an infinite universe, every single photon from every single star has reached, and its
successors are continuing to reach, every single point in the universe until one star in the line of site has died.. but even then there are infinite
stars in that line of sight.”
“Watcher” thinks Poe is amusing but out of his depth as regards these matters:
“So Edgar Allen Poe *I do enjoy his literary works but that is neither here nor there* is a credible scientific source? And no, the scenario you
describe would not be the case. You assume that light can push light into the visible spectrum creating what you claim. Remember distant stars are
harder to see *read dimmer* than closer stars and whether or not space is infinite doesn't even factor in.”
The discussion gets ugly, with both of them accusing the other of using “ad hominem” arguments. In rhetoric this is an unforgivable sin. It
turns into a cat-and-dog fight.
Further ahead, on page 4 muzzleflash says, “why is the infinite universe not overflowing with light? several reasons
as mentioned earlier - light dissipates as it travels , or dimming
also, asteroids, planets, rocks, dust, gas , etc will block light
therefore it would be impossible to have a superluminous sky even in an infinite universe.”
Page 5 and beyond are still Terra Incognita for me but I’m working on it.
