What is the downside of using nuclear energy? I know that a nuclear meltdown would wreck a city and be an enivronmental disaster for decades, but I've heard that new reactors are much safer these days, and if we put more nuclear reactors in remote locations, I don't see how this could be a problem...(I think this is a better price to pay than dependence on foreign oil, which seems to be stirring up WW3 and the more scary prospect of the threat of nuclear war...doomsday)

Why petrol is the only victim of the Global worming concerns?
I think that to take a narrow look on that problem is dangerous.
Therefore my question:
Is the electricity pumping causing Ionization of the oxygen and the ozone by the taking electrons from them and holding them in the electric webs.
If I am right than increasing of Electricity ”production” as a substitution for the carbon energy sources will give us much bigger problems then we can imagine.
If some one knows the physics and have time to answer Please let me know.
Am I right??

The reason I ask is this is that if somone actualy wanted to teach intelligent design in a science class I honestly don't knwo how they could come up with more than 15 minutes worth of class room material to discuss it. I persoanlly think its not a real scientific theory, but just out of curiosty, I waned to know people's ideas.

It's a circular column in a double volumn space. No way to pour it in one time (8m height). Is't necessary to stop first pour in the middle, or where?

OK, I know that this sounds like a dumb question but I'm having trouble trying to find out how to put in the matrix in TI-89 and get it in the row echelon form, reduced row echelon form, to solve it and so on. If you are familiar with TI-89 please help me to find that out. Please, describe me the simplest steps on some example.Thank you!

I have always read that if Jupiter had been of sufficient size it may have formed a small dwarf star. I understand star forming dynamics and the star is determined by its mass. It is not like a stars say, " get out of here all you not hydrogen and helium molecules." there still has to be residual larger elements within the star. I imagine most would be in a plasma state because of the intense heat and energy. Some molecules when given enough time and pressure crystalize like carbon becoming a diamond. Would these heavier elements become compacted in the center of a star? If so, I guess you could change the color of the star by adding enough mass. (It would need alot though)

I have to make a rubber band powered car for science. I have no idea whatsoever! I don't even see how a car can be powered by a rubber band! Can you tell me how to make one and how it works?!
Thank you.

Today, it is thought that a black hole's gravity is too strong for light to escape, but at the same time x-ray radiation does escape from black holes. Given that light is one weaker form of radiation, that seems to be a contradiction of our knowledge of gravity.

Do we need to a adjust our understanding to be that black holes do not produce any light because the high gravity beyond the event horizon has changed the electron vs the nucleous ratio. Light is no longer be produced. It is not that gravity is able to hold it.

X-ray radition is produced from the tremendous energies within the black hole's destruction of each atom's neucleous. That is Einstein. The electrons from these atom's have already been stripped from the atom. The electron's that produce light were stripped at the event horizon. Therefore, no more light production within the black hole.
