4 anti-scientific beliefs and their damaging consequences

The rise of anti-scientific thinking and conspiracy is a concerning trend.

3 proofs that debunk flat-Earth theory

We're finally here! We've been counting down the 10 most popular videos of 2018. This is #1...

  • Hey flat Earthers, it's time to put your theory to bed once and for all! "There are so many proofs that the Earth is round, it's difficult to know where to start. And it's not okay to think that the Earth is flat; this is not a viable argument," says NASA astronomer Michelle Thaller.
  • Thaller explains three observable proofs that instantly debunk flat-Earth theory with irrefutable evidence of the Earth's round, curvaceous, gloriously spherical shape.
  • The ancient Greeks figured out we were living on a sphere over 2,000 years ago, and there are things you can do to prove that the Earth is indeed round—just go to a body of water and look at ships or boats on the horizon with binoculars. Watch the video for the details!

How skepticism can fight radicalism, conspiracy theorists, and Holocaust deniers

Why have some conspiracy theories been pushed back into the public? Because when you try to force them out of the mainstream, they'll find a wider audience on the fringes.

Liberal college students have taken to shouting down certain right-leaning speakers on campus that they don't agree with. Michael Shermer, the publisher of Skeptic Magazine, thinks that is the worst thing you can do. He posits that all you do when you prevent someone from speaking is make certain people want to hear them more. This has led to the rise of the conspiracy theorists and why fringe ideas—from something as silly as flat-earth believers to something as morally reprehensible as Nazism and Holocaust deniers—have been pushed back into the mainstream. Michael's new book is Heavens on Earth: The Scientific Search for the Afterlife, Immortality, and Utopia.
