Big Bang Theory

How can all matter came from an explosion that occurred from something that is a square centimeter. And if this is true and the universe is still expanding, how do constellations still in perfect form for thousands of years. Wouldn't they be expanding as well?

Well there are three problems with your opening argument...

>>"How can all matter came from an explosion that occurred from something that is a square centimeter."

This is not true. We have no idea how big the mass of the universe was prior to the big bang. However, it is estimated that the mass of our sun would have been compacted to a size several miles across. Considering we have the technology to understand the physics involved up to BILLIONTHS of a second following this phase, it's not so far fetched at all.

>>"And if this is true and the universe is still expanding, how do constellations still in perfect form for thousands of years. Wouldn't they be expanding as well?"

There's the slight problem of humans only being around for thousands of years out of the almost 14 BILLION years the universe has been around. Recorded human history spans only about 6 thousand years. That's only 4 x 10^-7 percent of the time the universe has been expanding. That's 1 TEN MILLIONTH of 1 percent. Small wonder we haven't observed much change.

There are several reasons I believe the big bang model, most of which are rooted in fairly elementary astrophysics.

1. It was proved in 1924 that the universe is expanding. Elementary measurements of the red-shift in light coming from distant galaxies proves they are moving away from us. The big bang easily provides the energy for this movement of the galaxies.

2. Cosmic background radiation (CBR) provides evidence of the nature of matter immediately following the big bang. This was discovered in 1964 in Holmdel, NJ at the Bell Laboratories with their radio telescope. CBR is the radiation that escapes a group of extremely hot atoms as they begin to congeal, much as happened in the formation of matter after the big bang.

3. We can study the nature of matter as it was in the big bang inside particle accelerators. This study corresponds to what we observe in nature, giving us little doubt that the beginning of our universe was very similar to the collisions in a particle accelerator.

Just a slight overview, but three completely different arguments of why the big bang is a extraordinarily probable cosmic event.

This does beg the question however, if the big bang did not occur, what did?

This round was forfeited because my opponent has no argument against cold hard science. Sometimes the truth hurts.

Well I'm devastated.... I'm not sure what to say. Con opens with some questions, and no real arguments. I provide 3 solid pieces of evidence to refute his claims (or really opinions...).

Seems pretty clear which way this went.
