Ok, First I want to state upfront I am not a scientist, just a welder with an over active brain and a question that has been keeping me up at night.<br />I've been searching through posts and lurking for awhile I keep reading that FTL travel is at this moment due to current Hypotheses impossible, mostly due to mass increase at relativistic speeds.<br />So the question is energy, you have to eject mass backwards to accelerate forwards in a linear fashion, so first I thought about ejecting photons IE light or another EM wave then I read photons have no mass. <br />My question Is if Photons have no mass how can they be affected by gravity ? Like a black hole sucking in Light ect. if it is due to space warping around the black hole then wouldn't that make space a medium in it's own right that light has to travel through.<br />Another thing why do they always show black holes warping space into a cone, if a black hole is caused by a collapsed star wouldn't it exert the same force on space in a 360deg globe ?<br />thanks in advance for info or even pointers to find this, I did take physics in High School but either I didn't pay close enough attention or we never discussed it.
