Big Bang, Deflated? Universe May Have Had No Beginning

[yuiyoshida]

If a new theory turns out to be true, the universe may not have started with a bang.

In the new formulation, the universe was never a singularity, or an infinitely small and infinitely dense point of matter. In fact, the universe may have no beginning at all.

"Our theory suggests that the age of the universe could be infinite," said study co-author Saurya Das, a theoretical physicist at the University of Lethbridge in Alberta, Canada.

The new concept could also explain what dark matter — the mysterious, invisible substance that makes up most of the matter in the universe — is actually made of, Das added. [The Big Bang to Civilization: 10 Amazing Origin Events]

Big Bang under fire

According to the Big Bang theory, the universe was born about 13.8 billion years ago. All the matter that exists today was once squished into an infinitely dense, infinitely tiny, ultra-hot point called a singularity. This tiny fireball then exploded and gave rise to the early universe.

1. So we are NOT stardust? Damn. n/t

[Javaman]

10. nope, just accidental soup.

it happens. but personally, I think we could use a little salt. lol

11. Shoot. So my daddy was right. lol. n/t

2. and how does he explain the redshift of the expanding universe? Why is it expanding, or for that

matter what is it expanding into

[DetlefK]

5. This is not about expansion.

This is about how small exactly the universe was before the expansion: Was it infinitely small (singularity) or did it have a finite size?

[still_one]

7. Actually the expansion is explained by the singularity. How does he explain it?

That is what the Big Bang is all about

His theory is the universe was infinitely large and started out that way. How does his theory explain the redshift?

[DetlefK]

9. ??? No...

1. He postulates that the universe is infinitely old, not infinitely large. (The theory of the universe being infinitely large was calculated and discarded decades ago.)

2. For example: You can expand a balloon. But that doesn't mean that the balloon was a singularity before you expanded it.

3. When my doc says I've gained 5 lbs..

I tell him it's not true! That's just some random dark matter attached to my butt...nothing that a diet or exercise would help.

4. This has been my theory for a long time

but this isn't an area I actually study and I am not a science nerd. It is just something I thought as I was studying these subjects in school. A young universe just doesn't make sense not to me and not in light of that big mass that they have found that is like bigger than a billion suns. Someone that is more into science could probably give me ten reasons this theory doesn't make sense.

6. The premise is weird.

http://arxiv.org/pdf/1411.0753.pdf

The propose a Bose-Einstein-condensate that consists of particles in their ground-states, with little to no momentum. But they propose that those very same particles are ultra-relativistic... (I guess, because they need the energy to spawn all the heavier particles.)

And they don't take into account the decoupling of particles from the cosmic equillibrium. Cosmic neutrinos have an average temperature of 1.9K, the rest of the universe has 2.7K.

8. Existence/reality as we know it..

Is "Endless" with no beginning or end. (My Theory)...A endless sea of Black hole's leading to "Parallel Universe's".. The "Big Bang" was just our Material Existence/reality extruded through a massive black hole. The science theory says material enters a black hole but where does it go...? or end up. Bingo,...The big bang (so-called).I believe this to be the best explanation.And it's all mine.
