If eternity future is possible.. why not eternity past?..

The Big Bang model holds that everything that now comprises the universe was once concentrated in a single point of near-infinite density.

Well now, if you concentrated a single atom into single point it would be literally of infinite density, wouldn't it? So how stupid is that? Just wondering.

We know what happened after the ‘Big Bang’ - “The Big Cigarette” okay I stole that from Johnny Carson.

[Imnidiot]

Far out! Except for the fact that everything has a beginning (even his endless cycles of universes), it makes perfect sense. Cool.

[Kevmo]

for your various ping lists

Still does not explain the origin of information or morality!

OH.... THANK YOU.

Something to talk about besides the MYSTERY MISSILE and BRISTOL PALIN.

Now I can go back and read the article. Had to get that out to you, right away.

God has no beginning and no end.
Penrose’s view of a cyclical chain is compatible with that mystery.

The actual Gurzadyan & Penrose paper is here:

for those who can understand it, a group to which I do not belong.

"Penrose believes these circles are windows into the previous universe, spherical ripples left behind by the gravitational effects of colliding black holes in the previous universe."

[YHAOS]

In the beginning there was . . . something . . . ??? . . . maybe?

Beep.

Whaaa/ The Big Bong?

My understandig of entropy is that it is a word ,just a word, for disorder of phenomina. So if a disorder in nature of any kind exists it has entropy which in some sciences can be described by symbolic e.g. mathematical manipulation(s). Maybe this gets us closer to defining existance.
I also would ask the question- If at some time past existance was some tiny dot(maybe not so tiny) what happens to our perception of space?

Here is what I take issue with, in these BANG threads.

I was taught the Universe was infinite and everlasting.
The concept there was a big bang implies it is finite.
Scientists claim they know the size of the Universe, when actually it is just the limits of their equipment. That’s why, over time, the ‘size’ of the Universe has increased. Ironically, at the farthest edge of the viewable universe, where the matter should be the thinnest, in the darkest spot we can find, it is packed full of galaxies.

So, the word UNIVERSE needs to have a standard definition.

Is is either infinite, or it is not. If we could settle that, it would make discussion so much easier.

The Big Bang model holds that everything that now comprises the universe was once concentrated in a single point of near-infinite density. Before this singularity exploded and the universe began, there was absolutely nothing - indeed, it's not clear whether one can even use the term "before" in reference to a pre-Big-Bang cosmos, as time itself may not have existed yet. In the current model, the universe began with the Big Bang, underwent cosmic inflation for a fraction of a second, then settled into the much more gradual expansion that is still going on, and likely will end with the universe as an infinitely expanded, featureless cosmos.

I'd love to have someone try to explain the mechanism behind this expansion.

If black holes, which are only part of this universe, exert such a strong gravitational field that even light can't escape, how do they explain how the entire mass of the whole universe could be contained within this minute point, and not be trapped forever in it by its own gravitational pull.

How did it escape itself? What kind of and amount of force was necessary to overcome that kind of gravitational attraction?

[csense]

The universe's continued expansion into eventual nothingness causes the black holes themselves to evaporate, which ultimately leaves the universe in a highly ordered state once again, ready to contract into another singularity and set off the next Big Bang.

All Penrose achieves here is in unnecessarily complicating the dilemma by forcing the question, how does nothingness contract. But I say unnecessarily because the ordered state that the universe expands into, according to his proposition, is indistinguishable from the ordered state that it contracts to. Something that Penrose doesn't understand, or simply refuses to address.

“key assumptions in Penrose’s theory, particularly that all particles will lose their mass towards the end of the universe.”

Oh goody! So I can quit dieting, quit exercising and quit counting calories - just wait until the universe ends and poof, my weight is down to a healthy level!
