QuoteThe rocky object that wiped out the dinosaurs 65 million years ago may have been a comet, rather than an asteroid, scientists say.
The 112-mile (180 kilometers) Chicxulub crater in Mexico was made by the impact that caused the extinction of dinosaurs and about 70 percent of all species on Earth, many scientists believe. A new study suggests the crater was probably blasted out by a faster, smaller object than previously thought, according to research presented this week at the 44th Lunar and Planetary Science Conference in The Woodlands, Texas.
Evidence of the space rock's impact comes from a worldwide layer of sediments containing high levels of the element iridium, dubbed the Cretaceous-Paleogene (K-Pg) boundary, which could not have occurred on Earth naturally.
The new research suggests the often-cited iridium values are incorrect, however. The scientists compared these values with levels of osmium, another element delivered by the impact.
Their calculations suggested the space rock generated less debris than previously thought, implying the space rock was a smaller object. In order for the smaller rock to have created the giant Chicxulub crater, it had to have been going exceedingly fast, the researchers concluded.
See? Them their sientists keep chanjing there mind. Only teh BIBBLE is unchanjed!

Osmium! Exactly! Just what I always thought. You can't wipe out dinosaurs with iridium. For a job like that, it takes osmium, or better yet, full strength Osmium Plus with bleach.
You need the bleach to get your whites whiter. That just totally sounded racist when I repeated that in my head.
I don't know about you guys, but if I came into possession of a time machine, the first 'time' I'd visit would be the Cretaceous period just to witness these magnificent beasts. They were far more worthy of the Earth than Humans have ever been and likely will ever be.

And he was never heard from again.

I suspect they actually went extinct after caveman 'cowboys' rode them to death as so eloquently depicted at the creation museum.
So a comet hits the planet and 70% of the existing species die off. But there were no people then. I think if a similar sized comet hit the planet today, it would be a matter of hours or days before we killed each other off and took nearly every other living thing with us.
Scientists would immediately realize that the ability of the planet to sustain the current population would be severely impacted for years to come. Those scientists would inform their leaders of this. Their leaders would decide to nuke everyone else lest those countries nuke us first. Next thing you know, everything and everyone is dead or dying. We're humans. We fuck shit up. Its what we do.
I've never fucked anything up in my life... everything has gone completely as planned since birth..

Yeah, except the Earth would probably end up being populated by the descendants of crazy people with concrete bunkers, bottled water and canned goods.

Yep. The only survivors would be the preppers because they're ready for that sort of thing and the Duggars because there is just no way to kill all of them. That's evolution for ya.
