Except in the case of fluoresence/phosphoresence, light is light and equally visible before and after being reflected (still interacts the same with your retina). The light shining on your space suit will be scattered so spread over its whole surface rather than the pinpricks of distant stars but there won't be any more light visible.Clearly, light will scatter of your hands without having to go via the spacesuit... although if you're holding the palm of your hand up to your face it will be in the shadow of your head and only reflected light will shine on it.
quote:Originally posted by HadrianI was thinking that light is both like a wave and like a particle. Particles don't need medium to travel through, would particles travel better when there's nothing for them to interact with. Is light is like that, too. Would light travels faster in a vacuum than through any material?
