### Segment 1 (00:00 - 00:00) []

Without dark matter, we wouldn't exist. It had to collapse and clump and make proto galaxies before ordinary matter could do it. — You're telling me that there protogalactic dark matter galaxies out there? — There were in the early universe and then ordinary matter felt in there. — It wouldn't so much be dark cuz that would imply it absorbed light, but they don't interact with light. They would just be invisible. — Well, made of dark matter, right? So, — There's nothing to see. — Well, except No, no. If it if if it doesn't interact with light, right, — then light just passes through rendering them transparent. — No, because of Einstein's gravitational lensing. — Oh, you see the lensing effects. — You see distant galaxies, the light from behind the dark galaxies will get bent. — Okay. So, it gets bent, — but the dark matter thing itself would be invisible to you. — Yes. — You could just walk through it and you wouldn't even know. — Yes. — Ooh, that's cool. — Chuck, have you met my dark matter friend?
