Technically Incorrect offers a slightly twisted take on the tech that's taken over our lives.
Not everyone believes in climate change.
Some skeptics -- and even deniers -- are in positions of power and influence.
Stephen Hawking, however, has little time for their rhetoric.
In the second-ever episode of "Stephen Hawking's Favorite Places," -- which just started streaming on CuriosityStream.com -- the famed physicist uses Venus as an example how things can go wrong for a planet.
"Venus is like Earth in so many ways," he explained. "A sort of kissing cousin." Ah.
"She's almost the same size as Earth, a touch closer to the sun. She has an atmosphere," he said.
So he flies down to check Venus out -- thanks to some quite rudimentary CGI.
He gets through the clouds of sulphuric acid.
Sadly, he finds that the pressure on Venus is around 90 times that of Earth. "Enough to crush a submarine," he said. The temperature? A balmy 200 degrees-ish.
This is what happens, he said, when greenhouse gases are out of control. And this, he fears, is what will happen to our own planet.
A 2002 NASA study suggested that around 4.5 billion years ago, Venus, like Earth, enjoyed water. But, as the planet warmed, there was more water vapor in the atmosphere. More heat was trapped and a feedback loop continued until the oceans evaporated.
