You can say, how much is the form of hydrogen?

How much is in the form of helium?

How much is in the form of lithium, beryllium, boron?

I keep going up the periodic table.

And you'd get that 90% of that material that's in the form of matter, 90% of that 1% is basically hydrogen.

You know, the hydrogen or maybe it's slightly more hydrogen in the form of matter that we have in molecules.

Then the rest would be basically almost nothing.

So like the 10% of the 1% of the ordinary planets, rock stuff that we have is like stuff related to human beings.

Okay.

So we're almost not even the, we're like one grain of cinnamon essentially on the foam, on top of the latte, you know, sitting there steaming away.

So dark matter is the second most abundant source of energy, mass energy in the universe.

And we've known about its existence for a hundred years.

We've been able to infer the existence of dark matter for almost 100 years, and yet we've never, ever detected it.

And it may be impossible to detect it.

So this person that you were listening to, by the way, probably makes the rounds on podcast channels just the same.

And I know it's hard to sometimes tell the difference between a legitimate scientist, like I hope you're convinced I am.

And someone who might be doing stuff for clicks or for attention, I don't know that person.

Maybe they are, maybe they're not legitimate.

But there's a lot of pseudoscience and nonsense that goes on on podcasts nowadays.

So you just have to consider the source.
