And that results in that negative pressure that wants to pull those two plates together. That's called the Casimir force. A guy by the name of Casimir was a guy that derived that back in 1948. But it took us until the late 90s to actually measure this in the lab to the physics community's satisfaction. And so it's been studied.

hundreds of times since measuring forces at different regimes, if you will. And there's also something called the transverse Casimir force. So when you try and slide those two plates relative to one another, the vacuum wants to resist you sliding them. those two plays. And so this is a very real phenomenon.

And it's a wonderful illustration of the peculiar nature of reality at the microscopic level, right? So, you know, the theory was worked out in the late 40s. The experimental stuff was started in the 90s. And then there's been a bunch of work since then. And I think they're even looking at trying to use the Casimir force in MEMS devices. But all that- What is a MEMS device?

Microelectromechanical machines, some small gears that you can't see with your eyes, but they serve different purposes that people are trying to come up with for sensors, maybe some things in your car, some future chips that might be in your phone or something like that, things where they make micromechanical systems that they make them with light because you can't even see those kinds of things.

So... The quantum vacuum, this fluctuating field of particles and forces and so forth, is a very real phenomenon. And so this stuff I just described to you is the negative vacuum energy density that Alcubierre highlighted in his paper when he said โ We don't know how to make exotic matter in general relativity, so that circle on the Venn diagram doesn't tell us where to go.

But quantum mechanics tells us how to make negative vacuum energy density in the context of what we see in a Casimir cavity. And so maybe we can โ some future generation of scientists will figure out how to do something in some way to โ like if you ask what's in those rings around the IXS Enterprise โ Right.

You know, maybe it's some deeper understanding of the nature of the quantum vacuum and point. In fact, you know, I talked to you about. You asked me, when might this happen? And I said, I can't tell you when, but I know what I need to be doing next.
