I like forces, I find gravity interesting,

Hmm... good question. Physics gets very interesting when you read about the really high level stuff (String theory, quantum theory and stuff like that). A Brief History of Time is a good book which explains all those sort of things. I'll go for light (though colour is quite similar).

I like just the general space-i-ness of physics best, that we are just a tiny dot in a huge expanding universe.

It's pretty humbling, isn't it

It makes you realise that you are nothing special. You're just a life form living on a small insignificant planet orbiting around a star on one arm of a spiral galaxy.
Someone who weighs 50kg makes up about 0.00000000000000000000000000000000000000000000000017% of the weight of the observable universe.

wow! I like space, and planets. Does anyone know much about black holes??? I read something about them and don't they pull anything from miles around into it's centre, and as you get closer to the edge of a blackhole (well, if you could, because you'd be taken into the centre before you'd look at the clock.) time slows down. Does anyone know anything else. Black holes are interesting.

Sure, what do you want to know? You're right, black holes are interesting. The reason why they slow time down is their massive gravitational pulls. Gravity slows time down.

The class next to ours in science today were watching a video about black holes today. I tried to listen, but those stupid things called walls muffled my hearing!

A Brief History of Time has quite a bit about black holes.

We did that. Unfortunatly, it was coursework, so it went wrong for me.

We were doing an experiment where we had a long strip of paper and we had to use alternating current to make marks on it. It didn't work for me and I eventually realised that I had it on direct current instead!
