Thanks hamster143. I think I can consider my questions answered. Thanks to both of you.

Thanks mgb_phys. I read somewhere that the amount of solar neutrinos hitting the side of the Earth facing the Sun are about the same as those being detected on the far side of the Earth. Thanks heaps for the non-technical answer. Does the change in the atom change its radioactivity?

I just watched the movie 2012. Now I know it's just a movie and a bit of fantasy. What I want to know is, is there any type of radiation from the Sun that can penetrate a few miles into the Earth's crust and have some sort of effect on the rock down there. For example, can the amount of...

Yes, but I didn't think of it like that. So it's no really a question worth answering... Thanks again for your help.

Thanks for the reply, Uk_Ghost. So the Earth, or any other planet, doesn't actually have gravity? I mean, is gravity just the attraction of two objects with mass? If an object was somehow isolated and couldn't interact with other objects, then it wouldn't really have gravity?

If I had a hypothetical gravity measuring device that had no mass, would it be able to measure the gravity of a planet, that does have mass, as it approached it? Or would it not detect any gravity because the device has no mass? I hope this makes sense...

Thanks very much for the responses. I read about the Inverse Square Law and Maxwell's 'update' of Faraday. So the magnetic field just gets weaker the further it gets from the magnet. What about my point two? The tone generated wasn't a tone that went from weak to strong or high pitched to low...

Does the strength of a magnetic field become weaker at a constant rate the further you get away from it? I ask this question for two reasons. 1 - When iron filings are placed on a piece of paper and and a magnet is placed under it, there are definite lines of magnetic force visible that...
