This is a pallasite meteorite a rare slice of an ancient asteroid believed to have formed between its metallic core and rocky mantle over 4.5 billion years ago.

Those glowing crystal sections are olivine, meaning you’re looking at the shattered inner remains of a lost world from the dawn of our solar system.

isn't all material technically 4,500,000,000 years old?

I just took a shit that would beg to differ

The universe is estimated to be 13.8 billion years old.

But it was mostly Hydrogen and Helium for the majority of it. Although I'm defining material as atoms now, so that also a matter of point of view.

It's still mostly hydrogen and helium

But, like, a little less so.

Older. We are all stardust from prior supernovae.

The question you're really asking requires more robust definitions of "material" and "old" then you usually deal with.
