How small is small? How large is large? My own little view of the Universe(s) is that everything is connected to everything, so I am a part of everything and everything is part of me. We humans, with what we perceive to be highly functional brains, learn about the empirical universe(s) by measuring. So how far is it to the closest star from earth? On average, about 8 Light Minutes. The closest star is the one we call `Sun'. The Voyager 1 is approaching 20 Billion km away from us and the (reflected) light from earth takes about 18 hours to reach it. So it's about 18 Light Hours away. It took 38 (Earth) years for Voyager to get there. When we look up to the sky from earth, we are looking across time. The distance to the second closest star is 4.2 Light Years (approximately). It is called Proxima Centauri, a dim red dwarf star in the Alpha Centauri star system. We see it as it was 4.2 years ago! Here's some further distances to consider. All are approximate. Remember that as each distance listed increases, so does the time for the light to reach our human eyes. The distance is also how long ago we are viewing or measuring the object listed:As far as we know, this pale blue dot of ours is the only place in the universe where the universe has become consciously aware of itself. Ever human brain is a sense organ, governing the individual organism to which it is attached. But, above and beyond that, each individual brain and organism is also a cosmic sense organ experiencing the universe uniquely, and the universe is experiencing itself uniquely in and through it.
And, if the universe is self-creative--as it appears to be--and the self-creative universe is regarded as God, then every one of us experiences God uniquely, and God is experiencing ITself uniquely in and through every one of us. And everyone and everything is also inseparably united within this eternally self-creative singularity called God.
Farthest individual star visible to the naked eye: 2000-4000 Light Years. We see things from before the time that Jesus walked on Earth (and/or water?) with our own eyes. If you count the nebula and star clusters that we can see with our own eyes, the time and distance we see is 15 million Light Years! Estimated age of the universe, about 18 Billion light years. I cannot see that far. But parts of me are that old!
Atoms always existed - even before we `discovered' them. How small is small? How large is large? It is fantastic to be a part of IT all.
