A Coronal Mass Ejection, an Impact Larger Than Tunguska, and a Gravity-Deflected Asteroid - the Thre

追加: 2026-05-17

[00:00:00]We don't have the ability to cope with a major coronal mass ejection that targets the Earth. We're vulnerable to that.

[00:00:06]Now, all of these things, it's feasible to technologically address them, scientifically address these [music] threats. For the immediate though, I think that the most potential likely threat is an impact along the lines of Tunguska, Chelyabinsk, or, you know, an order of magnitude bigger. [music] The point is a slightly different trajectory or a deflection by Earth's gravity field, what can happen is that objects that are orbiting between Earth and Jupiter, they can get deflected and >> [music] >> over a a succession of orbits, they can close in on Earth.
