Reply to comment by redphoenix932 in Someone tell me how the Big Bang began 13 billion years ago, yet the *observable* universe is 83 billion light years apart? by novacks0001

space is chaos, it doesn't move nor can it do anything else. it is the nothingness between matter.

Space itself is expanding everywhere we look, flinging distant objects away from us faster and faster. This is called the Hubble constant. Physicists have no idea why, so they call it ‘dark energy’.

Some of what you see in the night sky is already beyond our reach forever, even if we could travel towards it at 1.0c, because the objects have accelerated away from us in the interval since the light was emitted.

space absolutely expands, and that expansion happens at a measurable rate. I've no idea what you think you're talking about.
