Science & Mathematics - 25 November 2006

I am a highschool student(grade 12) and have been interested in space. I love learning about space and related subjects. I want to be an Astronomer. The problem is it requires math and physics. I love math but I am not good at it. I struggle in math often but I feel like I can't live without solving problems. Is this going to be a problem or if I work really hard I might have a chance at it?

Given that the universe is of infinite dimensions, could the "big bang" have been a localized event. one which has repeated somewhere in the universe several times? I have a difficult time believing that all the matter of the entire universe was compacted into any one location. Infinity can be a very hard concept to grasp but I do believe the universe has existed for infinity and will continue to do so. It just seems illogical to assume that there was no matter in the entire universe prior to any one astronomical event.

Consider the curve y=f(x), where f(x)= (x^2-1)/(x+2). Prove using the algebraic method, that f(x)>=a or f(x)<=b, where a and b are exact values to be determined.

Can you show me what is the so called algebraic method and what are the other non-algebraic methods of showing this?

My chem class did an experiment using a test tube with CuSO4.5H2O layered with NaCl then water. Iron nails were placed in the water.

By factual I mean supported by observable evidence viewable by all.. If there is no such evidence in your opinion then give observable evidence that disproves it. The Bible story of creation is here considered just another story book and is not considered observable evidence.

For the following reaction at a certain temperature, it is found that the equilibrium concentrations in a 5.00 L rigid container are [H2] = 0.0500 M, [F2] = 0.0100 M, and [HF] = 0.400 M. If 0.150 mol of F2 is added to this equilibrium mixture, calculate the concentrations of all gases once equilibrium is reestablished.
H2(g) + F2(g) 2 HF(g)

Recently I have done a ton of research. Why does NASA have so few pictures of the moon walks? How could they really misplace and lose the greatest footage of modern film? Flag, shadow, and other conspiracy theories and that famous mockumentary aside -- where are all the pictures? And how come the astronauts "can't" remember if they saw stars? What is that about? NASA has so few photos of the actual moonwalk it is ridiculous. If the astronauts really traveled through the radiation belts, how come they didn't take their rings off? Wouldn't radiation conduct and bury itself in jewelry? How come the power cords to the rover don't hover in low gravity? I am really not looking for conpiracy theories, just facts.

I have a theory that absolute zero (which has never been able to be reached despite alot of effort put into it) can be reached only in the absolute epi-center (ironic name in this case) of a black hole. We know that heat is made by particles moving, and hence why it is difficult to create absolute zero on earth, but what if there were a hyper gravitational drive such as a black hole to help negate movement of particles; IE packing in particles so tightly into such a small area that they are unable to move at all. With enough gravitational force wouldn't the particles shatter under the forces and create plates similar to what the earth has for layers or would it pack them in like packing peanuts and create an absolute zero environment?
