Ever notice how nobody ever scales pictures of the impactor/event even remotely correctly?
If the Kt impactor was 6 miles that gives a viewable surface area of about 55 square miles moving into a viewable surface area of about 100,000,000 square miles.
Napkin math scaling results in a general grasp of this as imagining having a 2-1/2 acre surface being impacted by a .20 cal bullet.
Now imagine the .20 round going in fast enough to your 2-1/2 acre target to create a uniform coating of dust over the whole thing, and a several foot diameter crater at the impact site.
If “artist impression” sized asteroids hit the earth at 15+ miles per second we’d pretty much just be a cloud of ionized gasses...
The Earth would shatter................
Why do you hate science so much?
