Ok, I got it.
I jut discovered the fetch tool.

"The 93 billion light year figure you cited is the diameter"...
/////
It makes sense that the cubic Cartesan Graph of the Universe would be 13.5 billion light years in every direction since that is the Age of the Universe.
Of course the actual light itself would emanate in a spherically shaped ball centered at the point of the Big Bang.
I did not read the link refered to yet, but the idea of 92 billion light years seems wrong, intuitively.
How could Electromagnetic radiation, (not visible light), which came flooding out of the Big Bang 13.5 billion years ago be any further away than 13.5 BLY?

There *are* some actual points of agreement between astronomy and Biblical literalists. For example, the Bible says the Earth has a sun and a moon, and astronomers agree. The Bible notes that there are stars, and astronomers agree.
What about the first verse Gen 1:1?
How was the "In the beginning" any different in principle that the present discovery of a Big Bang beginning to a previously non-existent universe?
It seems to me that Genesis was out on a limb until Hubble found suppport for the claim that the cosmos was NOT always there.
That would be a biggie, wouldn't it?

It turns out that space/time is not fixed, that space is expanding over time at a rate known as the Hubble constant, which is approximately 74 km/sec/Mpc (Mpc is a mega-parsec, a million parsecs, or about 3.2 million light years). Space itself (along with the matter and energy contained within it) that is a mega-parsec away is receding away from us at a rate of 74 km/sec. Space that is 2 mega-parsecs away is receding away from us at twice that rate, 148 km/sec. This recession velocity is due to the creation of new space in the intervening space.
Hmm...
That makes sense.
But I thought Dark Energy was deduced because this expansion of Space itself demonstrated that the galaxies were accelerating.

Hi Kofh2u,
1) Is your position that any breakdown of events into 7 stages lends support to the accounts in Genesis?
2) Don't you need 6 stages of events followed by a static 7th stage?
3) And doesn't your position mean that any breakdown of events into other numbers of stages argues against the accounts in Genesis?
4) Or more to the point, isn't the number of stages in anything irrelevant?
5) Shouldn't you be looking for actual correspondences between scientifically verified events and events in the Genesis?
For example, in your first diagram the 3rd stage still has no atoms, but on the 3rd day in Genesis there were already plants and trees "of every kind." Seems to me like there's no correspondence at all.

Hi Mr Percy,...
I don't think I can respond to this under the present dictates of the administration.
However, it is confusingthat science refers to the edge of the visible universe as being @ 13 billion light years away, while the Hubble Constant is used to explain that Space measures 93 Billion LY in diameter.
"But, as Law's team reports online today in Nature, subsequent observations confirmed the galaxy's great distance. Residing in the constellation Pegasus and named Q2343-BX442, the surprise spiral has a redshift of 2.18, which means it is 10.7 billion light-years from Earth and therefore existed just 3 billion years after the big bang. "
So what my question amounts to is a definition of Size of the Universe.
It seems that science is saying Space is way larger than the separation of the pieces of matter inside it.
But even that concept suggests that something is confusing when we "see" the most distant galaxies on 12 billion LY away, but talk about a unverse 8X that size.
How sure are we about these theories in regard to the size of the Space/time dimensions when astronomers talk about 12 BLY for the most distant galaxies?
Are we to asume that Space has expanded withput matter or energy present in the most distant volumes of Space?
And is it really the same thing to ask how large isthe Universe when we might ask how much space (empty and otherwise) now exists?
