The observable universe

A distinction can be made that there is a difference between our observable universe and the entire universe. One estimate implys that the entire universe is at least 10x10x10x122 times larger than the observable universe.

@Vette888,
How was that estimate made?

@Vette888,
Why didn't you just write that it's 122,000 times larger?

@rosborne979,
The exact formula for this hypothetical calculation was not explained. Scientists have said with a good measure of confidence that at most less than 0.0001% of the volume of the Universe is presently or will ever be observable to us. So considering that fact it is not unlikely that the entire Universe could extend out infinitely.

Move along please, nothing to see here, please don't take up valuable space thank you, there is no question in the OP.


"What is the size of the Universe? A very important caveat is to differentiate the observable Universe of the entire Universe. The former, of course, corresponds to the part of it that can be seen from Earth and can be seen as a sphere centered on us with a diameter of around 93 billion light years. We don't know what lies beyond that horizon, and because of the expansion of the Universe "we" will not be able to observe much farther away than that in the distant future[6] (in fact we'll actually see less and less)[7], but it's thought that very likely more of the same stuff that forms our corner of the Universe. The size of the latter is unknown and ranges from some past suggestions of an Universe actually smaller than the observable one, and in which distant galaxies would actually be images of closer ones whose light had been able to circumnavigate it[8], to estimations based on probabilistic calculations or in predictions based on the theory of cosmic inflation. In that way, we have lower limits that range from 5[9] or 250 volumes[10]. If the inflation theory is right size estimations range from an impressive 3x1023 times larger than the observable universe [11] to at least a mind-blowing 101010122 megaparsecsWikipedia's W.svg[12], which is practically infinite. This assuming it's not actually infinite, as stated above."

The text is 10^10^10^122

Hypothetical calculation? I can't say I'm 100% sure I understand what that means.

@roger,
I can't be sure for sure but I think you just invented the "not the null hypothesis".

It's Too Late

Copy/Pasted Wiki just to pass the time
There's somethin' wrong here, there can be no denyin'
Numbers kept on changin', then maybe you just stopped tryin'

And it's too late, baby now, it's too late
Though we really did try to loft it
Somethin' inside has died, and you can't hide
And I just can't waft it, oh, no, no

What was there before the Big Bang. Well there was no light or darkness. So what was there. There was not even nothing. Would could ponder this thought for all eternity and never have an answer. Another thought is what if the Big Bang never happens and the Universe never comes into existence. This is almost unacceptable just because there is a Universe and the idea that the Big Bang never happens boggles the mind. It's almost as though the Big Bang had to happen.
