Infinity...whoa!

To put a price on the most beautiful work of art to ever exist...One man paid $25 million to go into space for 14 days.

What an incredible scene to witness! What a feeling to experience! Weightlessness! Stars! The infinite darkness of the universe! Yet...our source of light..

The Sun.
Our source of light.
Heat.
Sun burns.
Vitamin D.
Happiness.
Squints.
Freckles.

I wonder how many more years the sun will survive. Like everything else in this world, it must have a beginning and an end! So many people ask "How old is the earth?" But who asks how old the sun is? An average main sequence star shines for 10 billion years until it starts to spread out and dim, aka a Red Giant. How much bigger will the sun be when it's a Red Giant? Will we, or whatever inhabits the earth at the time, be a part of a new era? An ice age? Or become extinct because of the harsh conditions? When the Red Giant phase is over and the sun is a planetary nebula....Mamma mia!!!!! How beautiful! A nebular explosion so close to us, so colorful and mysterious. Would the earth and the other planets in orbit around the sun be destroyed? Or would they no longer orbit the sun and just... float in space? Whoa. Floating in space is such a weird concept to grasp. When I think of the universe I think of it infinitely horizontal, I don't really think about it being infinitely vertical. Not that there is an up or down in space. Technically there isn't even an up or down that is consistent.. down all points to the center of the earth so why don't we call it.."core" ? Up always points out to the sky, to infinity and beyond! So why not call "up" something else? Yeah I know, it's easy. Up and Down. But. But... I don't have anything else to say.
