スターシップは地球を彗星や小惑星から守れるのか

Earth does not currently have any ability to, uh, stop asteroids.

Uh, now with Starship, we, we then have some ability to, to stop an asteroid.

A-actually, technically, a comet would be the real danger, uh, because there are billions, uh, if not more than billions, maybe trillions of, uh, objects that are, uh, in the outer solar system of them with, uh, that are very long-period comets.

An example that most people are probably aware of is Halley's Comet.

So forget the exact periodicity, but it's slightly under once per century that Halley's Comet comes by.

Many comets that have very long periods that we are on-- simply don't know exist.

And for example, the comet, uh, Shoemaker-Levy, uh, when that hit, uh, Jupiter, it made a hole in Jupiter the size of Earth.

So if, so if that did hit Earth, the-- game over. Uh, every-everything's dead.

Though anyways, there's always some risk of such a thing occurring, and the probable lifespan of, of life is just much greater if we're, um, a multi-planet and ultimately multi-stellar, uh, civilization.
