Stephen Hawking thinks we'll destroy this planet by 2127, meaning it will no longer be suitable for human life, so it is time for us to start searching for a new home. Hawking has set his sights on Mars.
I did not get the detailed version of his reasoning, just the NPR, Cliff's Notes version, but I figure it has to go something like this, man pollutes, man poisons, man is blind to his actions, and at the same time believes the smart people will find answers to all the problems he's causing. Man's faith in in the fact that he recognizes how stupid, selfish, and destructive he is, but believes there are people out there who don't behave like he does. He denies the effects of his action knowing how stupid that is, but figures changing his way of life isn't worth the hassle, so a little, white lie makes sense, the lie being that he has any effect at all.
Little? How many little lies does it take to make a big truth? Like light bulbs, it's as many as can be sold before the lights go out for good.
They say Donald Trump tweets or speaks more than four proven lies a day, every day. He would be the tobacco guy denying the harmful effects of smoking. He'd be the General Westmoreland guy talking about how we've already killed all the Viet Cong twice. He'd be the climate denying guy who thinks the world is just too big to be destroyed by us, little us. His understand of Malthusian economics appears to be about as great as his understanding of The Constitution. Nowhere does it say that the president gets to do whatever the hell he wants. It says the president gets to do that within reason. So of course we get a president whose ability to reason was learned over real estate deals. Location, location, location, those are the three things you need to know in real estate, right? And Donald Trump has the location he's always coveted. Like Yertle the Turtle he's climbed to the top of the heap. What was the moral lesson of that story?
Stephen Hawking is a big picture guy. He's seen how things come and go, how the processes of creation and destruction are constantly at work in the little spheres creating huge changes in the giant spheres. He may have decided that we are too unskilled in our understanding of how the little spheres work to have any chance of saving the large sphere we live on, that we are already too far gone, and our only hope is a new world.
Another scientist then refutes Hawking, saying that the carrying capacity of the earth is 35,000,000,000 humans assuming they consume 1500 calories a day, and this means that we have plenty of time to figure out a solution to our problems. He would be right if food production was the only problem, but it's not.
Our problem is a whole host of Yertels teetering on top of the backs of all the turtles beneath them, all scared to look down. Stephen Hawking has looked down and has seen turtles burrowing into the mud of humanity.
