Only 10% of the normal matter in the universe (baryonic matter made of protons, neutrons, and electrons) is located in the stars.
Where have all the baryons gone?

It seems like physics has been taking three steps backward for every step forward for the last 20 or so years. That is, there was a time when I thought I was close to understanding it. Now it seems hopeless. Consider cosmological inflation!

Yes, Rick there are alot of misconceptions about the Big Bang.
The more one learns the less one seems to truely know.

I guess physicists have to retain their jobs somehow. If the 'theory of everything' were discovered, there would be no interesting work left to do in physics except mindless computations.

IMHO, the only sin is ignorance, and such trite remarks as those above only seem to try to unsuccessfully justify ignorance.
Whoever generally believes that "Ignorance is bliss" is an idiot.

This can also be taken to mean that, in the process of learning, one becomes increasingly aware of how much more one must learn in order to achieve competence

Exactly what I meant Dan.
Thanks 4 the clarification.

http://www.sciam.com/article.cfm?chanID=sa...52383414B7F0147Was it a colossal explosion? Can galaxies recede faster than light? How large is the observable universe? Even astronomers frequently get the answers wrong.
....The expansion of the universe may be the most important fact we have ever discovered about our origins....
....Forty years ago this July, scientists announced the discovery of definitive evidence for the expansion of the universe from a hotter, denser, primordial state. They had found the cool afterglow of the big bang: the cosmic microwave background radiation. Since this discovery, the expansion and cooling of the universe has been the unifying theme of cosmology....
....James Peebles of Princeton University, wrote in 1993: "The full extent and richness of this picture [the hot big bang model] is not as well understood as I think it ought to be ... even among those making some of the most stimulating contributions to the flow of ideas...."
....Because expansion is the basis of the big bang model, these misunderstandings are fundamental. Expansion is a beguilingly simple idea, but what exactly does it mean to say the universe is expanding? What does it expand into? Is Earth expanding, too?

If expansion of the universe continues, as most cosmologists now believe it will, space will become a cold, lonely place 10's of billions of years from now.

Don, do you agree with this quote of Socrates?
It makes sense if 'True knowledge' is different to 'knowledge'. But this implies that knowledge is never equal to True knowledge.
If True knowledge did exist we could, therefore, not know about its existence.

I don't know if I know nothing,
or should I say I know I don't know nothing.
I think what Socs' was saying is that as you unlock and open one door a multitude of new options (information/knowledge) presents themselves, where one needs to find tke keys (information) to unlock the doors (knowledge) .
And, the more insight one gains, through elevated levels of consciousness, the more one realizes the massive potentialities that exist out there and one becomes forced to ask what is correct input and what is incorrect input, as data continuosly imprints itself into your stream of conscoiusness, whether consciously or subconsciously.

Does the mind mimic the universe?
Only 10% of the normal matter in the universe (baryonic matter made of protons, neutrons, and electrons) is located in the stars.
Where have all the baryons gone?
Do we only know 10% of absolute reality in all its truthful objectiveness?
Is the rest Dark matter, since we have as of yet uncovered it's existence and therefore, truth about the nature of reality?

Of course, one who earnestly endeavours to uncover and answer some of nature's riddles never truly knows nothing, for a definite buildup of information and knowledge does occur. Its just that one becomes more aware of the amount of information that one does not know.
