a blog i wrote a good few weeks ago...

well anyway..... we were in physics today learning about how matter can have a wavelength and how light doesn't have a mass...

However i struggle to believe this theory. a) light exist in this world.. and to me for it to exist it has to have a mass... yeah??
yet here my physics teacher is telling me it has no mass yet it has a velocity, momentum and all this other stuff... which are related to mass mind you....

and also a fellow student raised the point about black holes....
if the black holes in space suck everything into it including light....it would have to have a mass... cos for gravity of the black hole to suck in the light, the light would need to have a mass.....yet here we are being taught it doesn't have a mass... hmmmm...


a tidbit to chew over in your mind......
ah well... those are my thoughts......
