You know, one thing about this speed of light thing and traveling through
the galaxy has always puzzled me. In literature on modern cosmology I keep
reading that the universe is around 15 billion years old since the big bang
from which everything started. We now have telescopes that can bring in
light that left galaxies some 12 to 15 billion years ago. So, if the big
bang started us all out from the same point at the same time, and nothing
can travel faster than light, how did we get here first to receive that
light? It's a puzzlement.
