Earth Day!
Are we alone in the universe. The notion of infinity is so
compelling that one might be tempted to think that there
really should be another planet very much like ours, voire identical.
No, not really. Infinite space and infinite time are not the same
thing; infinite time is a narrative, and could be a series of quite
unique events.
And this is our current view of space/time: an evolving physical system
creating space as it evolves.
You're all alone, Blue!
