And it blasted out into the universe surrounding it. And that happens enough times in our galaxy that the galaxy is actually a pretty polluted place. It's smoggy. It's dusty. It's dirty. And the dust is actually little microscopic meteorites. So on my website, BrianKeating.com, I give away – actually, I have a special link, BrianKeating.com slash Huberman.

I will give away actual meteorites that come from your ancestral homeland of Argentina. And you'll see when you get them, they're highly magnetic. They're very dense. And I give you the material, the composition of these meteorites and the assay. We do X-ray crystallography on them. It's really cool.

The actual composition of them is determined by this last event that a star does before it dies, which is to produce iron.

So we did discover a microwave signal from the galaxy, not from the Big Bang, not from the cosmos, but from particular and unique to our galaxy, which is that when a star explodes, it produces this material, mostly made of iron, these micrometeorites that I talked about, put on my website for your listeners. And these micrometeorites are also going to act like little compass needles.

They're highly magnetically susceptible. So the Milky Way, everything in the universe has a magnetic field. You have a magnetic field. Birds have it. Even bacteria can have it. And our planet obviously has it. And the galaxy has it. What happens when you put a compass in a magnetic field? Those needles get aligned with the magnetic field. That then produces a type of polarization.

Now, polarization is the least familiar. Light has three characteristics. Its intensity, its color or spectrum, and its polarization. Almost nobody knows what polarization is. But it's really the essence of what makes light a wave. If you think about an ocean wave, the ocean wave is going up and down, undulating up and down.

And the undulation, the direction perpendicular to the sea surface, is sort of its polarization. Happens to be that water waves are actually polarized longitudinally, but forget that. Or if you and I, separated by a meter and a half, two meters, we have a rope between us. If we oscillate that rope up and down at a certain frequency, the frequency will be the spectrum, the color of the light.
