Asteroids have been crushing Earth for nearly 300 million years and no one knows why
Fox News ^ | January 18, 2019 | Chris Ciaccia

Asteroids have been hitting the Earth for nearly 1 billion years, but the atmosphere has largely shielded the planet from some catastrophic events. However, some space rocks make their way through — including the one that wiped out the dinosaurs.

But a new study notes that, over the past 290 million years, asteroids have been impacting the Earth at triple the rate they were previously and scientists aren't sure why.

After looking at 1 billion years' worth of asteroid impacts on both the Earth and Moon, researchers found that dinosaurs' fate was perhaps an inevitability.

Remember that Gary Larson cartoon? God is watching his monitor as a grand piano is falling toward some guy on the sidewalk. God is getting ready to press the SMITE key on his keyboard.

Uh, we were in the wrong place at the wrong time?

Yeah, that’s been a theory — that sea level changes affected them. There’s also been a hypothesis that they were affected by increased volcanic activity. Bottom line is that no one really knows for sure at this point.

Maybe we are targets in an intergalactic shooting gallery?

Pretty sure it’s gravity.

Well, can we (cheaply) alter the trajectory of the few dangerous ones to hit the moon instead of us? After all, isn’t that is what the moon is for?

I always liked the opening where Bruce is driving golf
balls at protestors from the oil rig.

Good times!

1. Because there are more rocks in space than what we can see and detect.
2. Said rocks are in their own orbit or are being drawn to the sun.
3. Our own orbits intersect with these rocks of various sizes with varied levels of effect on us.
4. If we can only cut back on the use of carbon based fuel this would stop happening.

Maybe because we are in the way.

Those darn dinosaurs...

If the dinosaurs had invested more on their space program and less on their SUVs and lame liberal social programs (that didn't work) they'd still be here today.

Even use the moon’s gravity as a cue ball and knock the bigger ones in another direction, say Mars or Venus! Home Run!

It is still theory. What they came to realize about a decade ago is that a bunch of ‘critters’ (mammoths are a great example)...died in a sudden manner. We aren’t talking about a hundred years, or a year, or even a month...but an event that pretty much wiped them out in North America in a matter hours/days.

A lot of this speculation goes back to this meteor event and the rapid evaporation of the North American glacier....during the Younger Dryas period (12,900 years ago).

I'd say trajectory and momentum where gravity is, of course, a constant.

This is starting to look like a calculus problem...

We're in a snowstorm.
A very slow motion snowstorm indeed but eventually everything will be covered.
