We're Thankful for What We Have
A Perfect Balance >
Often the hectic time around Thanksgiving may cause us to forget why we celebrate the holiday in the first place. With all the food and football and family to worry about, it's easy to get caught up in all the extraneous activity with nary a thought of thankfulness.
So, now that we've had a few days to regroup, make yourself a turkey sandwich, pour yourself a warm glass of turkey juice, and we'll look at some reasons to be thankful from the cosmic Big Picture perspective. Let's begin on Earth.
Thankfully, our planet is made of just enough "stuff" and is just the right girth to have just the right gravity to hold onto just the right gasses. Meaning, we get to hold onto heavier life gasses like oxygen and nitrogen and carbon dioxide. But we can't keep a grip on the slightly less weighty death gasses, like methane and ammonia.
Thankfully, our seemingly insignificant Moon keeps us tilted just right, has slowed our "day" to a comfy 24 hours, and provides us with life-enhancing tides.
Thankfully, our planet is just the right distance from the sun in just the perfect orbit. Any closer to the sun, we fry. Any farther, we freeze. And our orbit, being nearly circular, keeps us at just the right distance all year long.
Thankfully, we have some Big Planet siblings way out there with a planetload of gravity. This wonderful gift allows them to slingshot wayward comets and asteroids out of the solar system or just suck them up altogether. This has prevented us from getting struck more often, keeping us from constant and nasty day-ruining phenomena called global mass extinctions.
But, thankfully, they are also just the perfect distance away from us to leave us alone. If they were closer, our orbit would be all out of whack and we'd freeze and/or fry.
Thankfully our sun is a lowly G-type star. This is a type of star that is just the right size to lead an entirely long and boring life. Slightly bigger stars pour out a lot more radiation and live shorter lives. Smaller stars may live longer but have less life-giving radiation to feed a hungry life-filled planet.
Thankfully, our sun is a loner. Most of the stars out there are multi-star systems. If we had a system like that, you wouldn't be reading this. Two or more stars throw a planet's orbit all over the place or toss out the little guy altogether.
Thankfully, our star system is about two-thirds the way out from the center of our massive galaxy, the Milky Way. Closer to the center means lots more stars, more deadly radiation, and more life-erasing supernovae. Farther out there is less planet-building rocky stuff since matter is so dispersed "out there."
Thankfully our universe is expanding at the rate it is. If it had expanded more slowly, by now the gravity of all the universal bodies would have caused the universe to slow and then collapse on itself. If it had expanded any faster, there could have been little to no time to have huge pockets of stuff come together leading, with perfect timing, to the formation of stars and galaxies.
There then would not have been enough time for the formation of an average yellow star at the center of a nice little life-ready solar system --- a system which included a perfectly placed, perfectly sized, tiny rocky planet with just enough water and the perfect atmosphere to be a home to creatures which could see the beauty of the universe around them and then be thankful for it.
