we are all stardust
no but really
I mean except for the hydrogen in you. that came from the dawn of time itself
this chart changed my fucking life
you are 10% hydrogen by mass. all of it is leftovers from the raw energy of the explosive first moment of the universe
the very same hydrogen in the water in your blood, that hydrogen. all of it formed in the immediate first seconds of creation. it took nearly 400,000 years for it to cool down enough to become an actual gas as opposed to a dense hot plasma, and literally the entirety of time more to finally end up in the water you drank today
@starwall What frame of reference are those time estimates based on? CoMoving Objects?

What is the age of the universe in the Cosmic Microwave Background FoR? Could it be used for estimates as well? Or is it inherently less accurate?
