Gravity will begin to pull the galaxies back towards the center of the universe. When this happens, every galaxy will show a blue shift in it's spectrum. Recall that a blue shift means that a galaxy is moving towards the earth.
As galaxies race back towards the center of the universe, the matter and energy will again come closer and closer to the central area. After many billions of years, all the matter and energy will be once again packed into a small area. This area may be no larger than the period at the end of this sentence. Then another Big Bang will occur. The formation of a universe will begin all over again. A universe that periodically expands and contracts on itself is called a closed universe. In a closed universe, a Big Bang may occur every 80-100 billion years.

This is what's being taught to our children in school.

It's bad enough there's no evidence for the Big Bang, that it's just speculation being passed off as science, but where can they possibly have evidece for a "closed universe, and multible big bangs?" And a time period, every 80-100 billion years. They would say anything to avoid a Creator.
Anyone agree with me, this textbook is giving speculation and not science?

I'm just showing what's in the textbook, and being passed off as fact. There is no evidence for this, and shouldn't be passed off as proven.

Theo...............this is just one example of the lies being taught to our children, the textbooks are full of them. They take non-proven speculation, and present it as fact.
If our children are told from the 1st grade on that the universe is billions of years old, they will never believe in God or the Bible.

That is not textbook speculation, it is following the observable laws of science to their inevitable conclusion. Gravity draws objects of mass together. This is undeniable, unless of course you say "God makes things fall to earth" - in which case there really is no hope for you. The thing which is not known is whether the energy of the expanding universe will continue to be more than the gravitational pull of the matter created. As for there being no evidence there is PLENTY of evidence. If the universe is not expanding then why do galaxies move away from each other? Why does light shift to the red end of the spectrum, suggesting that the source of said light has got further away since it was emitted?
Multiple big bangs will always be a matter mostly for philosophy, as there could be no EVIDENCE for it (you see, that's what science needs before it says 'this is so' - not for it to be written in a book from the iron age) - as all matter and energy from a previous universe would be contained within the singularity and would therefore leave no trace of itself in its previous existance.
I hardly think saying "a big man in the sky did it" is a more logical or reasoned argument.

The 'Big Crunch' idea looked good for a long time, but in fact there were always three models: 1. Closed, 2. Flat or 3. Open.
These correspond to 1) the universe being able to overcome its expansion, and recollapse; 2) the universe continuing to coast until it slows down to nothing in infinite time, and 3) the universe expanding without limit, with gravity never pulling things back together.
The first really good data indicated that Flat was correct - which was a bother, because why would gravity and expansion be so closely balanced? But that was all blown away in about 2003.
Some astronomers studying supernovae discovered that there's actually a mysterious repulsive force that is *accelerating* the expansion of the universe! Dark Energy seems to be the cause, and herds of cosmologists are trying to find out why and how.
It will never recollapse, and will keep expanding, faster and faster. Exciting, huh?

And damn right the children should be taught that.
It makes sense.
But it isn't multiple big bangs..... it is only the one. It just repeats itself.... Time isn't as linear as you would assume.
As for galaxies accelerating away from each other.... that is true, but yet they will still come together.
Think this way... If someone runs away from you in the street..... they may be moving away.... but if they keep running all the way around the world, still moving "away", they will eventually come right back to you from the other direction. And who is to say the Universe won't work the same way? It makes far more sense than to assume that it has genuinely unlimited dimensions.

Ya... lets teach our kids about the christian god that finds blood sacrifices "pleasing" in the old testament...and how god needed Jesus blood in the new testament to make everything alright!!! Lets not for get to included the fact that the best idea god could come up with to populate the planet was incest!.....The kids love the talking animals in the bible too...the donkey, snake....and who could forget the burning bush!
You Christians are nuts....your god is a god of blood offerings!!!
And you wonder why the rest of us don't want you in our schools, courts, or governments!! You should all be locked away in a nut house!!!

Dark energy is causing the Red shift of the Universe to increase.
The Universe is expanding and doing so at an increasingly fast rate.
Latest data indicate this theory you mention is incorrect

This is scientific not religious and it's far from certain that the Big Bang/Big Crunch cycle happens. It is a possibility, the other major possibilty is that the Universe will continue to expand forever.

Possibly.. Think about it this way. All the gold that you see was created most likely in a supernova. So all of the tons of gold and silver on the earth was created by a star that exploded before our solar system was here. Simple mind bottling.

Latest research suggests no pulling back. The expansion of the universe is accelerating.

OH MyZ! I hAVE AbSlUTeLY No iDeA! :P hmmmm... well, i know that my hair is blonde, and i know that the Earth's water SHOULD be blue, and that we should all contribute to saving the whales! SAVE THE WHALES PEOPLE!! lol jk
But anyways, I have absolutely no idea. When I get to talking about all of this mind boggling stuff, it just gets so deep!
