"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! You can follow Michelle Thaller on Twitter at @mlthaller. - Dr. Michelle Thaller is an astronomer who studies binary stars and the life cycles of stars.
