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.
Only hydrogen and helium formed shortly after the big bang. The heavier elements like carbon were fused inside stars later, and the heaviest during supernovae. The carbon in that meteor is the same age as the carbon on Earth, since it was part of the same dust cloud that formed our solar system.
Yeap this is correct. I was just trying to illustrate the general idea in my reply. Things get funny on the other side too when you start considering decay and halflife as well.
And the heaviest from neutron star collisions.
The absolute heaviest is when your mom collides.
I mean, technically yes but typically when they say something is formed at the Big Bang they mean in the hydrogen/helium state. Because while it's probably true that everything has always existed from the beginning of time, it hasn't stayed in the same state or form for very long.
