thanks guys. its funny that the more indepth into these things you go the more it is based on guess work. as how do we prove space is bent without actually going there because we have no way of accurately measuring spaces shape. The universe is a huge and magnificent mystery. I am lucky enough to see two supernovas happen and it boggles the mind to think i was watching something that huge yet it happened many thousands of years ago. The entire planets astronomy is so far out of date it boggles the mind. also i cant remember where i saw it but i remember scientists slowing the speed of light at super cold temperatures through a crystal to around 38 miles an hour. just found websit take a look:- http://www.jupiterscientific.org/sciinfo/slowlight.html I find it very frustrating that we will probably never truely understand the universe as it is like an amoeba trying to understand chess. Like star trek said "Space the Final frontier" Searching for answers is sometimes more rewarding than finding out especially if you dont like the answer! lol World Round and earth rotates round sun spring to mind!

thanks guys but saying that photons zero mass or only have mass because they are moving so fast makes no sense gravity from say a black hole only works on mass and also if mass increases infinately at speed of light there must be a mass to increase no matter how small and even the smallest mass no matter how small increased by infinity would be infinate not tiny ergo either our idea the affect of light speed on a mass is incorrect or light has infinate mass. The greatest achievement in science is the understanding that we know nothing!

Ok bear with me according to einstein nothing can go faster than light. as any any object at that speed would gain infininate mass which would obvioulsy be a problem. However as i understand it Black holes are formed by having such a strong gravitational pull that even light cannot escape. Now what this implies and I stress implies because we do not know for sure, that light has some mass for the gravity to effect. By logical reasoning this means that light traveling away from the black hole will have a force exerted on it strong enpough to slow and then reverse its direction taken another way light heading towards the black hole will have its speed increased by the same force. From this I come to two conclusions: firstly that photons have mass and secondly that faster than light is possible Very hard but possible as the idea of mass increasing as speed increases upto the "impossible speed of light" to be completely incorrect because simply put if a photon has mass then it is under the same rules as any other mass which would lead to light having infinate mass. Hope that makes sense thought about this for a while and cant see a flaw but please feel free to comment
