Neil DeGrasse Tyson on why we should - or maybe should not - go to Mars

“The universe is under no obligation to make sense to you,” writes Neil DeGrasse Tyson is his new book titled “Astrophysics for People in a Hurry.” He talks about the multiverse, time travel, and why he opposes the idea of putting some humans on Mars in case a catastrophe wipes out Earth. Instead, he argues we should go to Mars for scientific innovation.
