Great great observations and discussions guys. Love them. Space and time has always baffled my mind. Recently I just read that what ever we been taking for granted or else how we thought universe was created called Big Bang might not be the start really. They are saying that universe started before Big Bang. Big bang was just a collision so there was space and universe before that. Although not related to science, like Vedas say time is not constant I totally believe in it coz time slows down in space and our atomic time in earth is completely different if we take time in space so I truly believe that speed of light is the fastest in only in this universe. I am sure there are photons that travel faster than speed of light. As much as I try to go deep in study about space I feel like I am stuck by the black hole. It's too complex and we have really small amount of answes right now.
