If we want views, we have to go conspiracy theory.

We got to go Sasquatch, we got to go UFO, UAP Chronicles.

and all the moon landing stuff.

Yeah, no, that's a very plausible scenario.

Yeah.

There are several challenges with it, but it is certainly one that is perceived as a potential explanation.

I should say the most likely explanation that scientists believe comes down to either changing the composition of matter in the universe to include this type of invisible matter or to include matter that we already know exists.

We already know we have detected dark matter.

It's just, it's a very incomplete form of it.

They're called neutrinos.

So neutrinos are every bit as real a form of dark matter as protons are ordinary luminous matter, non-dark matter or visible matter.

And now these are mysterious particles that have very, very, very light weights, masses, very low masses, and they travel at very high velocities, close to the speed of light.

But they have exactly those properties.

They only interact with nuclear forces, so they don't interact with

electrons or light, so you can't see them.

But we've detected them for 85 years now or 80 years, known about their existence.

But the problem is they don't make up, they do make up some of that 20% or whatever, 25% of the dark matter slice of that pie that we talked about.

But the amount that they make up is only about like a quarter of that amount at most.

So they're not sufficient to explain all the dark matter, but they give what's called an existence proof of it.

Like, you know, for example, if we knew that there – so the fact that there were dinosaurs actually gives some tiny credibility to the Loch Ness Monster, OK?
