Stony meteorites reveal the timing of Jupiter’s migration The gas giant caused iron-vaporizing collisions in the asteroid belt 5 million years ago.

The "million" in the article is spelled with a "b." It's also spelled wrong in the title of the piece at the site.

None of us would be typing here tonight if Jupiter had moved through the asteroid belt as recently as a few million years ago.

I was thinking 5 million years ago is the blink of an eye in celestial time. The age of dinosaurs was 75 million years ago. To have Jupiter careening around the asteroid belt only 5 million years ago would have caused catastrophic meteor showers on earth.

Jupiter “collected” those nasty asteroids billions of years ago. Such serendipitous, multiple events make me certain we are alone in the Cosmos.
