Neil deGrasse Tyson hit hard in an interview with Yahoo News and Finance anchor Bianna Golodryga.

Here are just some of the things he said of the USA:

“It’s the beginning of the end of an informed democracy, the moment people are debating whether an objectively established scientific truth is true. The moment that happens, there is no informed decision-making.”

“If you’re going to ignore their reports, there is no future for a country that wants to thrive in terms of its health and its wealth and its security,”

“If you don’t have that, just watch America fade. We’re already kind of fading. Just watch it continue to fade and just disappear.

It’s not a cliff, so you don’t know it. You don’t ‘oh, we’re stepping over the edge.’ No, no. It’s just, we’ll become less relevant. The world starts making decisions without us, where we used to lead those very same decisions.

”

“I’m so disappointed that the country that I grew up in ― that put men on the moon, that developed the internet, that invented personal computers and smartphones ― that people are debating what is and what is not scientifically true.”
