What can science prove?

[Frank]

I don't think it’s this simple, science can only explain what it convinces to believe. Science is our tool, and we can't even decide for ourselves what things are positive or negative. It is easy to prove a positive, but proving any negative is almost impossible. The idea of a negative may only exists in our heads. In reality I can only think of a few negatives(black holes, death). People use the idea of negative when dealing with numbers, poles on a batter, and good and bad.

Indeed proving a negative (e.g. proving god doesn't exist using scientific data or analysis) is probably an impossible task (although arguably with every affirmative proclamation made by science we can conjure up a negative). If I have a goldfish in a fish bowl I can easily think of an experiment to conclusively prove it isn't immortal (kill it)!
