A Collision in Space 466 Million Years Ago Is Still Hurling Asteroids at Earth

Astronomers have found that the majority of meteorites that regularly fall into Earth's atmosphere today are the result of an asteroid collision that took place 466 million years ago.

Using chemical analysis from rock samples around the world, the team discovered that before that colossal collision, Earth experienced impacts from many different types of meteorite, meaning that our planet's history with meteorites is far more complex than we thought.

After examining the chemical makeup of these chrome-spinels, the team found that 34 percent of the pre-collision micrometeorites were primitive achondrites, a type of meteorite that only makes up 0.45 percent of the ones that hit Earth today.

They also traced some of the samples back to Vesta, the brightest and one of the biggest asteroids in the asteroid belt, which they say also experienced its own collision over a billion years ago.

These findings suggest that just because we experience a significant flow of L chondrite meteorites today doesn't mean that it has always been this way. In fact, the history of Earth's meteorite flux is only now becoming known.

Jeez. Can’t them asteroids learn to drive up there? Always a crashing into each other ‘n’ stuff! Land Sakes.

Coincidence? Hmmmmmm

Pff, it wasn’t the Russians. I bet there was a blonde trying to parallel park that asteroid that caused it!

Depending on the size of the rock, if it's going to bullseye an enemy nation, we need to let it.

You are in for a big surprise...

In that artist's interpretation, physics are totally ignored. The "impactor" has suffered not a trace of any effect -- much less reciprocal damage.

Whatever happened to "equal and opposite"...?

And the "10X" difference in mass is ignored, as well...

Are there no editors with brains left on this planet?

The larger object in the illustration must be of a lighter, looser material than the impactor -- but overall, yeah, both objects in that scenario would be getting vaporized, leaving hurtling small chunks going every which way.

[TXnMA]

I was referring specifically to the illustrator’s “heat glow” or “incandescence” — depicted on the larger object, only...

[SunkenCiv]

I’m pretty sure he’s not a professional illustrator, but point well taken. I think he did his entire body of work in the 1980s or 1990s, and at least some of it was done before SL-9 started hitting Jupiter in 1994.

Nope, no surprises for those that study the word.

The surprises are reserved for all you who will be gnashing their teeth as they watch.

Always!

This is not about reality; its fantasy universe.

I am at least as assured of my salvation as you are -- because my faith is in Jesus.

But, I'm not one who will have to stand before our Creator and explain to him how my personal hubris led me to insist to the world that HE must set His "daily clock" according to the rotation time of this third rate ball of dirt that He formed from matter that He Created billions of years earlier.

IOW, I don't allow my misinterpretation of Genesis -- for vain, egocentric, human reasons -- to blind me to the full, awesome TRUTH of His Creation.

Go right ahead; tell Him you don't believe He did this:

You’re assured of whatever the perpetrators of the ‘lies wherein there is no profit” are assured, but that will fall short of the wedding feast on the sea of glass mingled with fire.

Itching ears are pleased to hear that Torah has been cancelled due to lack of interest. That leads to “outer darkness,” as Yeshua assured.

The hubris is all yours here. Man made nonsense does not an eternity make. Earth’s inhabitants were the purpose of his creation, and the rest is stage props that he has promised will burn with fervent heat soon.

"hey also traced some of the samples back to Vesta, the brightest and one of the biggest asteroids in the asteroid belt, which they say also experienced its own collision over a billion years ago."

Now that is science. Not the waffling tripe of 'Climate change may cause beer bellies on men to expand twice their size in 50 years'
