Imagine a hollow iron sphere, say 6" in diameter and 1" thick. OK, you cut this sphere in half and magnetize it such that both pieces are N on the outside and S on the inside. What would happen if you forced the 2 pieces back together? It SEEMS like the S pole would be trapped on the inside, unable to connect to the N but that would be a monopole which doesn't exist, so what would happen?

this is for my Physics10 class, our professor challenged us to answer it. You have two balls, a smaller one within the larger one. You set it in freefall by dropping it from an elevated surface. What happens inside? Does the smaller ball fall at the same time? WHile in freefall, is it at the top or bottom of the larger ball?

I dont know much about this subject, but I find it fascainating. When I was in school, I remember my math teacher showing us this picture of a "shadow of a cube in the 4th dimension". It made no sense to me, but amazed me at the same time. I know that the 4th dimension is Time, and I remember her saying that we could not possibly imagine what a cube in the 4th dimension would look like, but that this picture would be a "shadow" of one in the 4th dimension. Does anyone know anything at all about this subject and can enlighten me?

From what I understand, the closer you get to the speed of light, the slower time moves. So theoretically, could our world have been created in the "six days" as purported in the Bible? Of course the sun hadn't been created till day 4, so I realize the inherent problem--but if they were indeed 'earth days'--with the relativity of time taken into consideration--is it possible if the observer were moving at the speed of light?

We are told that before the big bang, laws of physics as we know them today did not exist. No dimension or time. This being the case the bang itself was a change of state, so time must have been or the bang could not start? Please explain.

OK, so maybe I didn't add enough detail... if a point source of light (lets say a galaxy far, far away..pun intended) contains X photons/sec that are directed toward our own planlet, based on the distance (beyond 13 billion light years just for fun, imagine a shpere 13billion light years in radius and our planet as a single point on the sphere) and potential interference of matter (possibility of hitting a dust paricle etc. 0.00001% no idea on if this is in the ball park) how many photons /sec must be generated by the point source in order for us to detect that source today (given a collection/viewing time of 10 min with a 10meter lens)? in other words what is the required "density" ( yes I know the term is not correct) of light in order for us to detect the source? and the big one... how far away can a point source be and still be detected by our telescopes?
