Dinosaur-killing asteroid was likely a giant mudball, study says

NASA sent a spacecraft to intentionally knock an asteroid off its course.

One the size of Everest traveling 15 miles per second?

[dfwgator]

In before the Far Side cartoon.

[Boomer]

Interesting theory. Sounds plausible.

[Red Badger]

We don’t have anything that powerful except a Hydrogen bomb.......................and even that would be pathetic..........

That one is especially funny as the dinosaurs are furtively looking around like they don’t want to get caught smoking.

[Red Badger]

It reminds me of my HS days behind the gym.......................

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................

"...resulted in the extinction of an estimated 75% of animal species, including most dinosaurs except for birds."

Hurray for Chickens!

I never bought into the theory that some asteroid caused enough dust to kill off the dinosaurs. This is the THEORY that has been told over and over through the decades that it is now a fact (just like propaganda such as glowbull warming becomes fact)

There’s a thing called gravity. I recall when Mt St Helens blew its top off. Clouds of smoke and debris. Smoke is a fine particle and should be capable of staying aloft for some time. But over a few days it all came down. Mother nature has a cleaning effect in the weather department where much of it likely was collected in moisture droplets and fell, the rest came down naturally with gravity. No matter how high up this dust went, if there was gravity there, it came down in days or weeks - not years.

The same nonsense applies to Egypt massive stones that were supposedly moved by slaves pulling them on the sand using ropes and logs. That’s pretty much been proven a joke.

A more likely theory is a disease that killed them off.

Why do you hate science so much?

[Does so]

“One the size of Everest traveling 15 miles per second?”
.

What’s that in MPH?

Feet per second?

[Boogieman]

Well, it’s about 0.008% of the speed of light.

[Does so]

But not the speed of LIGHTNING..

Thanks Red Badger, nice twofer.
