I know it’s incredibly, vanishingly unlikely but what would happen if an object with these characteristics smacked into Earth?

- _joel 1y agoThe end, unless you're a small proto-mammal ;). An object (depending on consistency) of about 100m is enough to wipe out a city and do enough damage to the environment. Something of 8-20km is in the same category as what wiped out the dinosaurs (10-15km).
- padjo 1y agoIt’s going at 68km/s so I think even microbial life could be in trouble.
- _joel 1y agoYou could very well be right!
- AlexGizis 1y agoSeems like it arrives with a bit more energy than a 10 on richter scale: https://www.edinformatics.com/inventions_inventors/richter_scale.htm https://www.edinformatics.com/inventions_inventors/richter_s... No, I can’t really imagine what that means, either.

- ra 1y agoWith this much mass and velocity - it would smash the planet, rupturing the entire crust at the very least. No matter how infinitesimally small the probability - the universe is infinite, and so it probably will happen. i3 is much bigger than the Chicxulub asteroid that ended the Cretaceous period (and extinct all non-avian dinosaurs).
