how do my eyes work
Discussion
if i shut my eyes, i can't see anymore. I assume this is because light shoots out of my eyes and bounces off stuff and back into my eyes, allowing me to see. if i shut my eyes, then the lights can't get out so i can't see. This also explains why if put a torch up to your hand you can see light shining through your hand.

Yes, thats exactly how it works. 
So I guess that the torch shining through your hand thing, the torch actually gathers the light coming out of your eyes, the bits that make it through your hand, and reflect it?
Like a mirror but more powerful?
And also why, when I stand in front of a mirror I have red glowing eyes?
It all makes sense now!

this also explains why cameras give people red eyes, because human brains edit out the light beams from people's eyes, part of the reality filtering system the brain operates (whereby most of what you perceive is "filled in" by your brain), cameras however, can't do this.
also, this is the reason everything gets darker when you put sunglasses on.
telescopes let you see stuff far away by magnifying the light from your eyes down to tiny spots so it will shine a long way, if you don't do this is just bumps into stuff and gets lost, this is why humans can't see very far without telescopes.

You've been reading up on the history of how people used to think eyes work haven't you.actually no, I was just aware that people did once propose this explanation.
so anyway....
why if i jump in a lift that is going down do i feel light? (in terms of weight). If I am driving a go kart at 70 mph and i throw a frisbee how fast will the frisbee go? can i stop a train with a really, really fast bullet?
and whilst we're at it why are cats scared of brooms?

Paging 968...This new thinking answers a lot of questions for me, thankyou! Life is making a lot more sense now and I know not to look directly into the eyes of loved ones for too long to avoid damaging their eyes (worst enemies are OK though).
I was wondering though how come you can't see in a dark room even if everybody has their eyes open? Are the eye-beams afraid of the dark?

The frisbee will flip back and hit you in the face thanks to the wonders of wind resistance
No - a really big bullet perhaps - one shaped like a wall perhaps, but not a really fast small one. Unless you count the train exploding as a means of stopping it then possibly yes.
ETA I have no clue about cat psychology.
