a question about light

Postby Mattk61 » Sun Dec 27, 2015 3:14 pm

Hi, Just a quick question that ive been thinking about. There is probably an obvious answer.

light travels at 186,000 miles per second, so if I turned on a torch can the light from that torch be seen from that distance away? If not, why not?

I dont think it can, but surely if light travels so fast it should.
