The univers is expanding at the speed of light at the point of origen there must surely be a void created as matter is no longer being produced from the initial "BIG BANG" and as matter is being spread more thinly over time and space will the universe go on for ever or will it end not with a reversal of events through gravity or keep expanding into infiity until all light matter is extiguised and only dark matter remains.

Watch 9/11 Mysteries:

http://www.truth911.net

and Loose Change 2

http://www.seeloosechange.com

and this 10 minute video about strange explosions going off
at the Twin Towers before their collapse:

http://www.youtube.com/watch?v=Qa7PN-8T2VY

And this firefighter's testimony about what happened on 9/11:

http://www.prisonplanet.com/articles/august2007/080807_b_clinton.htm

Explain all the explosions happing in the basements and in
the lobby (ground floor) of the Twin Towers.

Explain all the molten metal, when it is a FACT that jet fuel
fire, (kerosene)
whose only source of oxygen is still air, does not burn hotter
than 250 C, and it is another 100% undeniable fact that steel
melts at 1532 C.

Explain all the molten liquid white/yellow hot steel DRIPPING
out of the South Tower, just before it's complete free-fall speed
collapse. (as if none of the lower materials below had any
strength at all)

MOLTEN METAL PRODUCED BY AIR FIRE! HOW?

People used it a lot 50 years ago, but now it is breaking apart. Some say they did not use enough cement, it has shale in it (scorio), it has coal in it. I think the sand may be too fine.Why doesn't it hold up over the years?

Suppose 8 marbles look identical, but once marble is slightly heavier than the others. Using only a balance scale, give a step by step "recipe" that will identify the heavier marble in exactly two weighting?

I have been searching the all over the internet for information on this insect and I can't find any. I think, but I might be wrong, that this is a hornet. It has one pair of wings, its thorax is hairy, and its entire body is black except its abdomen is half orange and half black. Also its legs are orange too. It makes its nest or home in the ground and its body is about 1.0 inches long. I have been searching the internet for some time now for information on this insect but can't find any.

ok , here is the question:

1) Does this function's graph intersect its horizontal asymptote?

g(x) = x / x ² + 1

2) Does this function's graph have more than one horizontal asymptote?

g(x) = | x - 1 | / x² - 4

3) Prove that the graph of every odd function with domain all real numbers must pas through the origin.

4) Show algebraically that -1 < 3x² - 1 / 2x² + 1 < 1.5


any help at all is appreciated, ~! thanks a lot~!! ^-^

It is my definition of religion:
Religion is a part of a person's identity. It is a part of daily life. Many people make lifestyle choices because their religion or lack thereof. It answers life questions that science cannot answer. It also provides security in life.
Can you help me make it sound more scientific,please?
