Easy enough. matter (disregarding it starting as energy) does have specific points where it can collapse to. In stars the pressure from electrons keep the star in equilibrium with the force of gravity. Usually in binary star systems a white dwarf (burnt out very dense star) collects mass from its partner star (this is one of the most well understood examples)
http://csep10.phys.utk.edu/astr162/lect/su...ovae/type1.html which increases the core mass until it hits what is known as the Chandrasekhar (sp) limit which is about 1.5 solar masses. At this point the star's electron degeneracy pressure can not balance gravity and it collapse causing a supernova. Huge amount of energy (greater than the luminosity of an entire galaxy) is released and what is left in the star is a bunch of neutrons that form a neutron star. This star is usually about 10 miles in diameter yet has the mass of our sun, spins incredibly fast (see pulsars) and is held by Neutron degeneracy pressure. If this star accretes more mass beyond another limit (I forget how much) then it collapse again into a black hole. A Black Hole is theorized to have all of its mass at a point source. It is not testable as nothing can get by the event horizon (the "radius" of a black hole). So it can not be studied.
~The black hole. Must be another "God did it" excuse. Can't observe it, but it just happened. Not impressed with your answer.~

I don't understand your question...the Big Bang Theory does not break any physical laws (otherwise it wouldn't be a theory!).
~We can play dumb game all day. It does not compute because it puts Big Bang on a level playing ground for evidence, and repeatable tests, that you would place upon creation. I guess that must seem unfair

If I understand your question correctly, you are asking how we know that the universe came from this point and yet it doesn't resemble what it was? I answered this in the post. The Big Bang Theory does not say that the universe began as a point source (there is debate over what people think was happening at T=0) but the Big Bang only says that in the extremely young times of the universe (around T=10^-43 seconds) that it was very dense and very hot. But the Big Bang did not expand into space. The Big Bang happened everywhere! It happened where I am, where you are, etc because space is expanding, not matter expanding into space, and the matter is mostly embedded in space (General Relativity). The universe did not begin as a rock, and didn't break into small pieces. It was a huge amount of energy that was spread for all practical purposes evenly (that is why you see the Cosmic Microwave Background and an Isotropic Homogeneous universe!). You can not date energy because there is no method for energy to have a marker! If I am not answering the question, please rephrase it.
~O yes, the multible bang theory. Where everything just blows up. Kind of like fire works on the 4th of July. Bang bang bang. I like the tactic of when one question is not answerable, switch to another theory, nice.~

What you have displayed is a planetary nebula (the Cats Eye Nebula I believe) which is caused by a supernova explosing. That gas is still travelling at very fast speeds, but the whole disk there is extremely large (thats not the explanation just a side shoot). I addressed this as the Big Bang did not start as gas, but as energy which later formed into gas as the universe cooled.
~Nice dodge. You dodged that question like a politician. But I expected that. Time frames and odds science now ignores because it shows how unfeasible certain theories are.~
QUOTE
I think my answer to (a) is that gravity keeps them together? I am not quite sure of your question. Believe it or not the book is not closed on gravity as there is no Quantum Field Theory to explain it (which would help physicists make a Grand Unified Theory!)
Yes, and I very seriously doubt they will ever figure it out. The smartest minds in the world

.
Another nice dodge.

And to B there are different theories. We are either in an open, closed, or critical universe which depends on how much matter is in the universe. There is some critical density that would collapse the universe as we know it. So we take the density we observe and divide it by that number giving us a critical ratio of 1 which means that the universe will expand forever but at T= infinity it would be stopped and it would not recollapse, if the critical ratio is greater than 1, then it will eventually collapse, and if it is less than 1 then it will keep expanding for an infinite amount of time and still be expanding! There is a postulation of a new type of gravity that acts at large distances known as the Cosmological Constant first hypothesized by Einstein, but for a different reason. In Einsteins time it was thought that the universe was in a Static or Steady State. Einstein ran his General Relativity equations with what we know now, and it immediately collapsed. He realized this isn't possible and added in a constant that was supposed to "repel" gravity at large distances. No physical law is broken and mathematically it works. But he realized after Hubble discovered the redshifts in all distant Galaxies that his equations predicted an expanding universe and that he didn't need the Cosmological Constant. We think about it now because we see that the redshifts in the past due to the expansion were LESS than what we observe now. This either means our data is wrong (but many people have observed this independently) or that there is something making it expand which is extremely new and exciting physics!
The reason science is not willing to commit to an open or closed system is because that would also make them commit to an answer. Being able to switch theories to always make things look explainable, and to make them always look right in every answer. Is more desirable. And is also the same reason a theory will never become an absolute. Never having to admit to being wrong requires this.
The theory of cognitive dissonance states that contradicting cognitions serve as a driving force that compels the mind to acquire or "invent" new thoughts (theories) or beliefs, or to modify existing beliefs, so as to reduce the amount of dissonance (conflict) between cognitions. The person who is caught up in this also gets caught in the need of always being right. Which actually feeds the other.

Tests are not just what can be done in a lab. If a theory postulates something that has not been discovered yet, then a test for the theory is whether the postulation can be discovered. This has happened in two cases. The first is the Cosmic Microwave Background, and the second is the relative abundances of the elements due to Nucleosynthesis. That is very solid evidence.
My point about Creation Science is that it does not expand on science and it does not make any new discoveries, but only works to either try to thwart science (which it has failed to do so) or it tries to find a loophole or "complexity issue" to say that there is a creator. This happens very often when there is a new set of data or discovery that is not understood. This is true with the redshifts (though they were a bit late for that one!) and continues with evolution and the like.
People of faith have a very hard time believing science for a few reasons. One, very few actually understand what the theories state. I have had enough christians not know what the Big Bang Theory is to verify this (the comments on this post have also agreed with it).
O yes, the: We are stupid because we won't accept your theory.
Unlike you, and people like Hitler. We don't need to force our views down the throats of all who would listen. And we don't make up names (childish) to call those who don't believe as we do, come up with websites to mock individuals (childish), to make our forced reality seem more true (A Hitler tactic).
Is there a class for this? Name calling and mocking 101? Or is it a part of science?

And on the last comment. Its funny how this website is a "place for honest, civil dialogue on origins" and yet the moderators are all fundamentalists? And there is a vast majority of people (as I have noticed) that are christian on this thread. To be a fair area of discussion there would have to be a larger amount of scientists than creationists because science is extremely broad and mostly dealt with by specialists in the field. A person who studies particle Physics is not a master in any sense with Cosmology and vice versa, nor do biologists have an understanding of quantum field theories etc. While we could just have the pope be the fundamentalist side or a few high theologins since I am sure a theologin is supposed to understand all of the Bible (but please correct me here if I am false, this is only an assumption).
Because of your attitude, I would call you a evolutionist fundie. If you don't like that word. maybe you should consider not using it yourself to call others that name who disagree with you.

I have heard of this noise that sounds in a forest argument, but thats not science, thats philosophy as far as I know. No scientist studies that. The redshift argument does not contradict itself, nor has anything I said. Please point out this contradictions so I may put forth a better argument.
I was asked this in science class. Because this is part of the brain washing needed to question reality so that science can place it's own reality in your mind. Then get you to do the rest. The reason I posted that question is to show how actual reality is always questioned to a point to where no one seems to know what real reality is anymore.
Answer to question: Sound does not require someone there to hear it to happen. That's real reality.

You figure out how to expand space in a bottle and observe it and that could happen! But...its not necessary to have a lab test, there are other ways to test things than in a lab. We know the weight of Jupiter by its moons. Do we put a scale under jupiter? No. But using our calculations that have been proven again and again to work, then its safe to say that we know the mass of jupiter.
And unless you have an actual absolute to compare that to, how do you really know you are correct in Jupiter's weight? In other words, what would be the sure way to check your figures?
So by saying you are right, but really having no sure way to check in a actual "proven method". Shows you just have created your own reality. Jupiter weights so much because a method says so. So what if another method comes up and proves it wrong? Your answer and reality changes. But if that method cannot be tested by an actual proven method. Then it is also up for being proven wrong as well.
But each method creates a personal created reality of truth that is controlled by the individual that decides to believe it (this is what makes it a religion). And if that individual can convince others to believe the same thing, then that reality becomes their own self made reality of truth as well. But do these self made realities change the actual truth? Nope.
