Science and U: First Sign of Aliens? - A Neighbor's Choice

Dr. Weiping Yu returns with another refreshing segment of Science and U. Dr. Yu comments on the claim by Harvard professor Avi Loeb that alien debris passed near Earth in 2017 and that it was the first sign of intelligent life outside Earth. A new research suggests that "maybe 'dark matter' doesn't exist after all." Dr. Yu says that's what he's been saying all along! Is there something fundamentally wrong with the way we think about gravity? How does the environment affect our minds? The answers may surprise you. Listen to the full episode for all this and more.
