| 6/1/23 | ![]() 56 - Asteroid Collisions Are Not Certain Extinction Feat. Professor Birger Schmitz | When we think of asteroid impacts, we often just picture Chicxulub and the mass extinction of three-quarters of the plant and animal species on Earth, 66 million years ago. But asteroid impacts can be less impactful to life, like the Popigai and Chesapeake impactors - not as big as Chicxulub but still big enough to create craters of over 80 kilometers across, way back around 35 million years ago. Cosmic material could even actually help life bloom. | — | ||||||
