You're listening to Bulletproof Radio with Dave Asprey.

Today's cool fact of the day is that being left high in dry is actually a good thing,

at least if you're a telescope, especially for something called Alma, the Atakama large

millimeter array.

And this is a telescope you've probably never heard about.

It's located on the 5,000 meter high Chinatore plateau in the Chilean Andes.

And one of the driest parts of the planet, in fact, they believe there was no rainfall

there at all for 400 years.

And this thing that you've never heard of has 66 high precision antennas with radio dishes

that weigh about 100 tons each.

Since 2013, we've been using this to study light from some of the coldest objects in the

universe.

This is molecular gas and dust.

It has a wavelength of light around a millimeter between infrared light and radio waves.

And we can look at things that we've never seen in the entire history of humanity and

see very distant light that's been shifted towards the red end of the spectrum.

In order to do something like this, it took thousands of scientists and engineers from

around the world more than a decade of work.

And it's a collaboration from four continents.

And it's the largest ground-based astronomical project in existence.

And the reason I'm talking with you about this is because, as you know, if you're a long-time

listener, I like to foreshadow what we're going to talk about in the show.
