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.

... because we have to beat China to growing vegetables on the dark side of the moon?

Correct and there is no way to test it so it will always remain a theory.

First, why was this not placed in Breaking News where it belongs?

Second, this is obviously fake news because it does not end with the obligatory and mandatory scientific observation, “more research and funding is needed.”

Third, they got the number of years wrong. It was 300 million LAST YEAR. This year it is 300,000,001. Obvious math error. Just careless.

It is our own fault, maybe we need to think about why the asteroids don’t like us.

Glowbull Warming - it has to be the cause afterall, anything that happens or even could happen that is bad, is caused by this.

A brown dwarf swept by waaaaay out past Quora and nudged the orbits of stuff in the Oort cloud? Maybe Kuiper belt too. It would take a long time for those nudged orbits to get here.

It’s a conjecture without any solid evidence. The Dinosaurs took a million years to die out. Plus there were many dinosaurs that were no bigger than chickens. The theory that they were too big and climate change killed them all doesn’t hold water. Something else was at work.

But since it’s an attractive theory we’ll pretend it answers the question and science can go merrily onward to bigger and better things.

Just think. Our solar system is about 2/3's out from the galactic center. Not all that much happening out this way in the boonies.

That's a good thing for most non-self-loathing people.

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).

Fractions of a second, in geologic time.

The researchers aren't sure what has caused the spike over the past 290 million years, but they believe it may be due to the "large collisions" that took place in the main asteroid belt between the orbits of Mars and Jupiter.

That would be about the time the planet that use to orbit between Mars and Jupiter was destroyed by the Martians.

"The Martian Race had encountered the people of the fifth planet, grokked them completely, and had taken action; asteroid ruins were all that remained, save that the Martians continued to praise and cherish the people they had destroyed"

("Stranger in a Strange Land" - Heinlein)

Nibiru was captured by our solar system 290 million years ago.

If you will only read the book “Not by fire but by Ice”, you will learn what it is that killed the dinosaurs, it was not asteroids. While it is somewhat complicated the problem is Volcanoes. It is a little complicated but Robert Felix in the book referenced above does a convincing job of explaining how its happens. It has happened several times in the history of the earth, mass extinctions that is.

The destruction “theorized” by some from asteroids is just theory and there is very little evidence to support the theory. There is much evidence to the contrary and it is interesting reading about it. I do caution anyone reading the above book, you will become a global warming denier if you aren’t already.

While many of the clues of what happened in the past are duplicating themselves we don’t know what yet to expect in the near future but for sure the global warming nuts are just that, nuts.

no one knows why?

We’re in a bad section of galaxy spiral arms?

Galactic collisions happen.

More likely that just appears to be the case. That the evidence from before is just no longer recognized because it has been mostly erased by time and occurrences, (other asteroids slamming into the earth, volcanic eruption, flooding), that have transpired on earth.

A better question would be “Why not?”

The about to be smitten one is likely right-handed.
