Mystery; Size Comparison of Stars, Planets, Universes, Galaxies

How big is the Earth and ‘our’ Sun compared to other Suns that telescopes can see and measure? In the video above, we explore this question. 

The biggest Sun that astronomers can see is so large, it would take a jet flying 900 miles an hour close to 1,000 years just to fly around it once. Our sun that the planet Earth revolves around would only be a tiny speck of dust by comparison.
How big is our planetary system, compared to the universe and nearby galaxies? How far away are they? What is the edge of the known and visible universe? These questions are answered by the above video. The mystery is contained in this size… 

We know so little about your own Earth, and we know almost NOTHING about all of these other galaxies, much less what is beyond the limits of what our best telescopes can see. 

Bottom line, there are more mysteries in the cosmos than logical knowledge. What we know in sum total is probably .0001% of the totality visible, if that much… We are not the center of the visible universe, and the cosmos does not revolve around us. If we can appreciate this mystery and embrace it, we may gain some measure of humility and reduce our hubris. 

As a next step, we may even start to think about what is good for seven future generations, instead of just short sighted ego and greed based thinking that consists of thinking just about what is good for me, here and now? We have been given the Earth in trust for future generations. Let’s treat it that way. Let’s leave in better condition than when we got it.
