Are their any specific dimensions. Has one tried to build and preserve something in such a structure? Does it get preserved? If yes why don't we use pyramids instead of a refrigerator?

Hypothetically: A hole is drilled directly and perfectly from the north poll to the south poll. A metal ball weighing 5 kg is dropped at one end (lets say the north poll). Describe exactly what would happen to the ball?

(Ignore air resistance and the fact that the ball would melt due to temperature)

I have heard that electrons don't fall into neucleus because they are moving at high speeds, but from where do they get the energy to move at such high speeds and why doesn't this energy diminish.

...I'm still confused. I was reading about PIR, or passive infrared motion sensors on www.howstuffworks.com and how they cannot detect anything behind a window. The article states that glass is transparent to visible light, but opaque to infrared. If motion detectors are supposed to detect IR energy (heat) and IR energy can pass through glass as some people state, then how come motion detectors don't get tripped?

Another thing I read was about greenhouses, and how they work by trapping in long wave IR energy on the inside. In other words, the IR energy isn't able to go through glass.

Err, could someone please clarify this for me? Thanks!

Ok not much on this kind of science so bare with me but I was thinking about how wood is a non conductor of electricity. Well my question is why is lightening still able to tear down thru a tree and sometimes split the tree. I first thought that lightening couldnt travel thru wood so then I thought there is a force or inertia traveling with the bolt. so does that mean the inertia is traveling at the speed of light? Seems to me if it was then we could learn to travel that way one day. Now this may be totally off the wall but i had to ask

I would like to know how to separate gold flour from a bunch of sand and dirt. I would rather not do this chemically as that can easily lead to spills and possible heath problems. I've had it assayed and it is a good purcentage gold, but I'm too new to prospecting to do this properly (first time actually) anyhow any help would be greatly appreciated.

imagine, that you have build a huge supercomputer which is able to simulate motion of atoms and waves in some small part of space. Now imagine that we have built exact model of spermatozoid and ovule and some necessary space around them.
Then if we run the simulation program it would be logical that after some time this model will become an embrion, even without our knowledge of how our brain works e t.c. just because of the laws of physics. And after some period this will become a human with the real intelligence. My question is, is there something wrong with this idea? Is it possible or am I missing something?
