That dust itself has information.

I wonder what we can learn from that.

It's that kind of thing that happens on every scale.

It can be anything.

Interference, background, static, all that stuff.

Imagine if you could figure out stuff from that.

That just changes your whole dynamic of what you're trying to be able to transfer.

Here is the dielectric substance that helped us find the cosmic microwave background.

That's not going to be a quick answer.

Can we just pick like one thing?

Go pick one.

I'll pick one.

All right.

But that's a tremendous question.

Wonderful.

Okay.

The one breakthrough I think is going to be amazing is the ability to fly spaceships in formation.

When you fly spacecraft that are basically going in lockstep with one another, not deviating by even a millimeter over thousands or millions of miles of travel, then you can use something called laser interferometry.

Shine and position the light and the detectors in such a way that we can find gravitational waves from space at a level that's hundreds or thousands of times greater than we can on the ground.

That's exactly what I'm talking about.
