I am very curious about black holes, ever since I was told that a teaspoon full of the material from the average black hole weights more then mount-everest. I would love to learn all I can about them, and thanks SO much for your help.

I was wondering why mars' gravity is only 38% of ours...
I thought gravity had something to do with it;s speed of rotation- but it's day is almost the same length as ours...
Please help!

Also when it says that mars has some spots of magnetism left from an old planetary system, what does that mean, and how did that happen?

So confused!!!!

What do Biologists think of media representations of cloning. They really p**s me off. You know when they clone someone on a tv show and the clone is an exact replica! They don't realise that a clone would form as an embryo and take just as long to develop. Anyone give me good and bad examples of media representation of cloning technology?

I know in the good old days before digital cameras astronomers would stay up all night looking through the sky. Nowadays, I'd imagine they just program the motorized telescope and digital camera and shoot all night automatically. That way they can sleep all night like a normal person and look at their picture "prizes" the next day. Am I right, or am I way off?

The directions are: simplify the following.
the square root of 5 TIMES the square root of 10 MINUS 2times the square root of 18

so the square root of 5 is one 'thing', the square root of 10 would be another 'thing' and 2 times the square root of 18 would be another 'thing'.
plz show show

Since gravity creates time out of the annihilation of space would it be correct to say that regions of space with no matter don't have time?
