As I was heading out into another sub-zero morning, I was pondering the gravitational pull of the our sun.
Now perhaps I’m naive, but it seems remarkable to me that we have maintained an optimal distance from our sun - for supposedly billions of years.
I’ve never seen one, but if someone is a aware of a chart or graphic showing the livable min-max zone in which human life on this planet is possible - I’d like to see it.
The reason it it interesting to me is that if there is an increase - or decay - of the our sun’s gravitational pull - of just a small amount, before two long (an eon or two), we would drift outside the livable zone...
