Big bang theory question
[From: ] [author: ] [Date: 11-04-27] [Hit: ]
The only thing we can say is that the Planck Time marks the beginning of the universe as we understand it.For all we know, something might have been expanding forever before that moment (whatever before means).-Before the Big Bang, present theory says all of the energy and matter that exists today was compressed into a point of singularity.Laws of physics dont apply to such a point.......
We are not sure how time itself could have flowed at that moment (or before); this does not mean time did not flow - it only means that we do not understand how.
To put it bluntly: we do not know how to apply the word "before" to that moment.
Therefore, some people go around claiming that this moment is the "beginning" of the universe. This might be an exaggeration. The only thing we can say is that the Planck Time marks the beginning of the universe "as we understand it". For all we know, "something" might have been expanding forever "before" that moment (whatever "before" means).

Before the Big Bang, present theory says all of the energy and matter that exists today was compressed into a point of singularity. Laws of physics don't apply to such a point. As to your point that Hydrogen and Helium take up space, that is not relevant to the period before the Big Bang. Hydrogen and Helium did not exist until after the Big Bang and expansion took place. More exotic particles existed initially, which cooled and combined with early expansion to form Hydrogen and Helium.

Umm.... yeeeaaahhh...
your understanding of the 'big Bang' is... limited. And not really right.
But you just go right ahead, there!

Your meter and rhyme is all wrong.
Start again.
Here is an example of a four-line stanza scheme from 'To Anthea, Who May Command Him Any Thing' by Robert Herrick:
Bid me to weep, and I will weep
While I have eyes to see;
And having none, and yet I will keep
A heart to weep for thee.

I'm only going to talk about part of this. "but the big bang was caused by hydrogen and helium exploding" This is not true, there was no hydrogen or helium. We don't know what caused the initial expansion in the big bang.
As far as how space came be to in the first place, well that's outside the scope of the big bang theory. In a VERY simplified form the big bang theory states that in the beginning of the universe all of the matter was contained in a very small space and then for some reason this space started to get bigger. Trying to use this theory to explain how space came to be in the first place is like trying to use Kepler's theory of orbits to explain why the Sun is there. It just doesn't work.
