Were did matter space time and matter come from. If the Big Bang only produced hydorgen and helium, how did we get all the elments? Were did the big ball of matter get it's energy? How do they know how old the universe is. How can they know that the big bang will happen agian?

Your question as to whether the Big Bang will occur again is one scientists have debated for years. It all seems to revolve around how much total matter, normal and dark, there is in the universe. The amount turns out to be an important variable in the equation: not enough and the universe can't keep itself gravitationally bound, so the universe goes on expanding forever, too much and the aggregate matter draws itself back into the primordial singularity - i.e., the Big Crunch. The current thinking is the former, I believe.
But creationists/intelligent design folks (and yes, they ARE the same thing) will tell you that because scientists are divided on this issue it proves that scientists know nothing. Debate is healthy and something the IDers should learn to appreciate. Of course their "theory" (barely qualifying as a hypothesis, really) won't stand any degree of scrutiny.

1. Hydrogen and Helium were not the "only" elements produced by the Big Bang and it's aftermath.
2. But, Heavier elements were produced in the "Furnaces" of the stars.
3. Well, the "Big Ball" was actually infinitely small and you might want to look at "String Theory" (Branes) and maybe "Fractal Universes".
4. Determining the "Age" of the Universe is just "Science" LOL
5. We do not know that the "Big Bang" will happen again in "Our" Universe. Not to say it may happen again in "Another" Universe.

Your questions require a course in cosmology.
The big bang produced only hydrogen. Heavier elements are made inside stars via nuclear fusion.
Mass and energy are the same thing, via Einstein.
Estimates on the universe's age are based off the redshift of very distant galaxies (how fast they are moving away from us), and the exact temperature of the cosmic background radiation - the echo from the big bang.
We don't know if the big bang will happen again...

To be honest, nobody knows the answer. But all of us can speculate.
Bigbang produced hydrogen, helium, then the continuous fusion inside the stars produce the rest of the elements.
where did matter space time come from? i think it simply existed, becuase this would be simplest answer, else if i think that 'x' created matter, then my next question would be what created 'x' ad infinitum.......
Man loves mysteries and the universe we live in seems to have infinite mysteries to keep us entertained for eternity. Hope you get the point :)

Where did it come from? We don't know. Why did it appear? We don't know. However, we can be reasonably sure that the universe had a beginning.
There was no explosion, there was (and is still) an expansion.

a)Atoms joining together.
b) Of the union of the atoms.
c) By chemical reaction of the atoms joining together.
d) Nobody knows it yet as the source of the big bang is still a theory
e) It keeps on happening but not as big as they have conceived of the big bang and they have been observing the living and dying of the distant stars.

They don't really know anything. It's just a theory that supporting mathematics and logic was developed for.

There are things Yahoo! Answers is useful for. This is not one of them. You need to go to Wikipedia.

i dont believe in that theory cause i believe only in God, He knows the origin of everyhting!right? Science is just a science! but God Is God!
