The political climate in the United States has Stephen Hawking, the British cosmologist many consider to be one of the smartest people alive, questioning his next trip to America, where he's spent quite a lot of time.
While his travel plans to the U.S. might be a little less certain, he says he's more determined than ever to get to space.
In a wide-ranging interview with Piers Morgan on "Good Morning Britain," the physicist was very critical of President Donald Trump's appointment of Scott Pruitt to run the Environmental Protection Agency.
As I've explained here at length, Pruitt made his name as Oklahoma Attorney General by suing the EPA over a dozen times and his vision for the agency's future seems to be anathema to its stated mission.
Hawking called Pruitt "a man who does not believe carbon dioxide causes climate change" and suggested that replacing him would be among his top priorities for the current administration.
"Climate change is one of the great dangers we face and one we can prevent," Hawking said.
