Still Waters

Ever heard this life advice? When solving a big problem seems impossible, break it into smaller steps.

Well, scientists just took one of geology's biggest controversies and shrunk it down to atomic size. By zapping single atoms of lead in a tiny zircon crystal from Australia, researchers have confirmed the crystal is the oldest rock fragment ever found on Earth 4.375 billion years old, plus or minus 6 million years.

Yes, but unless you were there to see the rocks form, you can't know how old they are.

Bullocks, the dating methods we are using are inaccurate. There is no way to tell how old it truly is.

They're actually not inaccurate. That's why we use them.

Regardless, if that image is the same type of rock, it's beautiful. Just goes to show that with age, there's beauty.

This article says a collision. A while ago an article here theorized the Earth stole the Moon from Venus. I feel like Vinnie Barbarino "I'm so confused!"

if every geologist in the world slammed their head into a desk upon seeing this post, it would cause a minor seismic event. fact.

I've seen the instruments used for this, in the basement at Geoscience Australia in Canberra. There are several around the world.
