Just a random thought. I was reading a headline about a galaxy that was 300 light years away. Did not read the details. But, I felt that 300 light years is a a bot short distance when it comes to galaxies. So, I checked the size of milky way and found it to be 100, 000 light years in dia. There are galaxies that are 980, 000 (M87) light years in dia and another one at 1.5 million light years (Hercules A) in dia.
But, how can it be? I dont claim to be good at Physics. But something tells me that there should be a simpler and closer path connecting most of the universe.
It was just yesterday that I was seeing a video where I heard that we really do not know what happened from 0 to 10^-43 sec of big bang. Well, so, there was no physics (at least as we know it today) during that time. So, matter could travel at speeds exceeding that of light in that duration. But, did matter travel that much distance in less than 10^-43 sec? Or, was matter always present at those points where it is currently present (or at least close to it)? What was really the speed of matter just after 10^-43 sec?
May be physics has answers. I need to read further :)
