I mean that a light source is put somewhere in an empty peice of space which goes on forever. Will the light produced by the source go on forever or stop somewhere in space

If you put a light source, lets say... a lightbulb or star, in a corner of a universe with nothing in it to block it or anything. What will happen. Will it go on forever or what and why?

My friends and I are doing a project on digestions and it would help if we could find out how to test for enzymes. Thanks:-)

I searched on google. Most came back with the answer: Melt it down and conduct electrolysis

You could but you would need a whole lot to disolve it

Yep create a big fire but I don't think water would do the trick. liquid Nitrogen should

Don't think it would work. The rock might blast into his house. Or get one of those plants like YT2095 said.

H2SO4 for cars even though i don't think they are used anymore
