Mu mum says that if I read under the bedclothes using a torch (flashlight) I will damage my eyesight. I told her it's an urban myth, but am I right?

I have read abt the scattering of light n all but that didn' make a good sense to me in text.. cud someone please explain it to me startin right with the basics!!

whenever I see nasa's space pictures I saw them colourfull but on other things like the video of astroids hittng the planet looks like black and white , why is it so?

I tried things on nasa website, they say bla bla about our eye sight and earth environment and light 7 rays. I don't understand.

There are several sets of pedestrian lights in Porthmadog . One green light flickers with a steady and definite pulse but only when I look a few feet to one side , when I look at it directly it is perfectly normal. It can only be because of where the image hits the retina , but why?

Whenever you see the Starship Enterprise off on a mission, an 'outside' shot always shows the vessel in full visiblity - but how visible would it be? must you always be illuminated by lights on the top, or a planet nearby? If we were away from any planets and suns, and I were to space walk a few hundred yards away from the ship, and it had no lights on the outside, would I only see stars and a black 'shadow' where the ship was? Or is there always residual light? could I for example see my own hand in front of my face? or is there a point where you can see nothing nearby, but only stars and galaxies in the distance?

If you have a current going through a fluorescent bulb tube and you smash it, for a split second there is a yellow flash as the gas escapes. What I'm wondering is what causes the yellow flash if the light coming out originally is a mix of colours that make white light?
