Olbers' Paradox.

Beyond the boundaries of established science an avalanche of exotic ideas compete for our attention. Experts tell us that these ideas should not be permitted to take up the time of working scientists, and for the most part they are surely correct. But what about the gems in the rubble pile? By what ground-rules might we bring extraordinary new possibilities to light? If you have a personal favorite theory, that is in someway related to the Electric Universe, this is where it can be posted.

I realize that the bigbang explanation for Olbers has a number of parts (which include physics that i cant fully understand), but i consider that the key part is that the BB universe is not eternal. Actually no other part is needed.

Yes.
Yet that answer is quite absurd and demonstrably incorrect. You could stand 1 metre away from a candle for eternity and never be heated to 1,000°C. Nor receive any increase over any shorter period of time.
The starting point for this single candle argument is that if our universe was infinite & eternal then the correct form of Olbers' Paradox should ask why isnt the sky at an infinite temperature. This cant be disputed.

If every star etc is replaced by candles, then crawler's paradox arises, & this is that....
......... if u then snuff out one candle at a time from every star then at what stage does Olbers' Paradox cease to exist.

The answer to crawler's paradox is that there is no intermediate stage at which OP ceases to exist.
(1) The first stage is reached when the most feeble star consists of only one visible candle. OP lives on.
(2) Then the next stage is when that one candle is snuffed so that that star no longer shines. OP lives on. There are plenty of stars remaining.
(3) Then the next stage is when the brightest star has only one visible candle. OP lives on.
(4) Then the last stage is when that one candle is snuffed. OP ceases to exist.

If u dont agree then u must explain where & how in between (2) & (3) OP ceases to exist.

Re (1)(2)(3)(4), what i am actually talking about are 4 steady state infinite eternal universes consisting of thems candles. U know what i mean. I dont actually mean one universe that is going throo stages, but the wordage is easier.

It can if you understand dispersion and distance.

Olber's misunderstanding is due to believing that the light from a star is a constant flow of photons as we experience from the sun. In that scenario the sky would be constantly white, as we would would perceive light from all directions. In reality only the nearest stars emit light that we perceive in this way (visible stars). For the rest they are so distant we may only receive 1 photon a second/day/week etc. which our eyes are not able to register. That's the reason the sky isn't white and has nothing to do with it's age or infinite existence.

Yes, mightbeso, but i am talking about an eternal infinite universe, a universe with no mechanism for removing energy, whilst somehow new stars are being created all the time.
The answer being that there is indeed a mechanism for removing energy, which has eluded mainstream, but hasnt eluded me.

Don Scott on Olber's Paradox

For stars/galaxies/clusters, dimmer than the 6th magnitude there is simply not enough light, as received by the human eye/brain mechanism, for perception. The sky therefore, looks dark.
Why would a bunch of invisible (to the human eye) things accumulate into something visible?
I copied Thornhill's comments from the THOTH magazine of 2004. The above posting from nick c is from page 1 of this present OLBERS' PARADOX thread.
Thornhill's comments & other theories have been digested on page 1 & 2 etc of this present thread. But i wanted to re-mention that Thornhill's theory seems to be incomplete, he gives zero explanation.
And of course we should have OLBERS & OLBERS' not OLBER & OLBER'S, but its too late to make edits.

OLBER'S PARADOX
By Don Scott

"Why is the sky dark at night?"

According to the following logical thought sequence (mathematical
derivation), it should be horrendously bright.

1) The apparent intensity of a light source decreases with the square of
its distance from the observer. (Assuming no interstellar dust absorption,
this is true. Lumens received from a star will vary inversely as the
square of the distance to that star.)

2) If the distribution of stars is uniform in space, then the number of
stars at a particular distance, r, from the observer will be proportional
to the surface area of a sphere whose radius is that distance. This area
is directly proportional to the distance squared. A = (pi)r^2

3) Therefore, at each and every possible radial distance, r, the amount of
light coming toward us should be both directly proportional to the radius
squared (the number of stars) and inversely proportional to the radius
squared (they get dimmer with distance).

4) These two effects cancel each other.

5) So every spherical shell of radius r should add the same additional
amount of light.

6) Ergo: In an infinite universe, if we sum (integrate) the light coming
from all the infinite number of possible values of r, the sky should be
infinitely bright.

But the sky is not infinitely bright. Why?

The resolution of this paradox can be achieved by considering how
astronomers solved the problem of defining the ABSOLUTE luminosity
(brightness) of a star. Because of (1) above, the more distant a star is,
the dimmer it appears to be. In order to set up a standard, astronomers
arbitrarily agreed that if a star was placed at a distance of 10 parsecs
(approximately 32 1*2 light-years) from us and if it looked like a
magnitude 1.0 star at that distance, they would agree to say that its
ABSOLUTE LUMINOSITY was 1.0.

There is a well-known relationship between distance and apparent magnitude
of a star. For example, if we put that same 1st magnitude star at a
distance of 517 LY (light-years), its APPARENT MAGNITUDE would be only
6.0. Humans cannot see any star whose magnitude is higher (less luminous)
than 6.4. The 200 inch Hale telescope at Mt. Palomar can see down to
about magnitude 23 or so.

There are approximately 8400 stars in our night sky that are brighter than
magnitude 6.4. We do not see the others; they are too dim. Yes, yes, Carl
Sagan used to talk about millions and millions of stars ? but we can only
see about 8400 with our naked eyes. Carl was well known for his tendency
to exaggerate. We get the impression of millions and millions when we
look up at the Milky Way, but we can see only 8400 stars ? that's it ? and
that1s under ideal conditions.

Of course, some stars are VERY much brighter than absolute magnitude 1.0
and thus would be visible farther out than 517 LY. But, many are much
dimmer too, so as a rough approximation let us consider the average star.
If it is farther away than 517 LY, we cannot see it (AT ALL). So it might
as well not be there AT ALL. The total light in our night sky (at least
the way we can see it with our naked eyes) is not affected by much of
anything that is dimmer than magnitude 6.4 (typical stars farther away
than around 517 LY). Even for the blue-white giant stars whose absolute
luminosity puts them at ?10 or ?12 (much brighter than absolute magnitude
1.0), there exists some finite distance beyond which they too become
invisible to us ? their apparent magnitude slips down beyond 6.4.

There are a very few vastly distant objects that we can see such as the
Great Andromeda Galaxy M 31. It is over 3 million LYs away. But it is
such a concentrated collection of stars and plasma that it looks to us
about as bright as a single magnitude 4 star.

The point is this ? the infinite sum implied in step (5), above, is
incorrect. The sum STOPS (is truncated) at a distance of about 500+ light
years for the typical star (and somewhere beyond that even for the
brightest ones). There is an upper limit on the absolute brightness of a
single star; there is no such thing as an infinitely brilliant star. So
there is a finite upper limit to the integration process described in step
(5) above. It doesn't go out to infinity.

It may also help to remember that the human eye is different from
photographic film or a CCD chip. It does not integrate over time. The
longer we expose a photographic plate to starlight the brighter the image
becomes. (There is a limit even to this process in film due to what is
called reciprocity failure.) But, humans can stare at the night sky all
night long and not see anything they didn't see after the first few
minutes. Things don't get brighter for us the longer we look at them. So
theoretically the longer we expose our CCD camera chip, the brighter the
image (deeper into space we can see). This is not true for the human eye.
We can see the 8400 or so stars that we can see, and all the zillions of
others might as well not be there AT ALL as far as our humble naked human
eyes are concerned.

Olber's Paradox is not a paradox at all if you look at it correctly. It
is yet another example of theoretical mathematics applied incorrectly to a
real world phenomenon. Or a mathematician might say, "They got the upper
limit on the integral wrong."

You are correct. The scientist who first proposed the famous paradox was named Olbers, so the possessive should be Olbers'. But seeing it written as Olber's seems to be common (though incorrect), and Wikipedia is even worse, where the title of the entry is written as "Olbers's". I posted a screen shot of the Wki page because they will probably correct it.

No it's not too late, at least for the title of this thread. The title has been corrected to Olbers' Paradox.
