The problem is that the universe is very, very large and the speed of light is very, very slow.
And as we can't go faster than the speed of light, so from the human perspective, the universe is set in concrete.
So here we are concreted into this tiniest, of tiny corners and we will never go zooming around even our own galaxy, never mind the universe.
And because the speed of light is so slow we can't even see beyond 13.7 billion light years. We are faced, thanks to the nature of light, with an event horizon at only 13.7 billion light years. Why, even the memory of my computer is measured at 2,000 billion bits. And my brain is much larger.
And to top it all off, the universe is accelerating away from us, and all except the Milky way will pass from our sight, so we are indeed light locked, forever.
