Thanks for the explanation! Those distances are almost incomprehensible to me.
Can’t help wondering what kind of life might exist in other galaxies. Maybe I’ve seen one too many reruns of the original Star Trek. Sort of took a shine as a kid to the lady with the green skin. :-)
Almost??
How about this then: We can currently observe galaxies that are an estimated 13-14 BILLION light-years distant!
That’s 13-14 billion TIMES 5.9 trillion (miles away), in ANY direction!! And scientists say all of this was once contained within a volume of space trillions of times smaller than the nucleus of an atom.
