Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

We are proud of the book for you.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

We are proud of you.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

Oh, you're so kind.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

Thank you.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

Thank you so much.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

Okay, please continue.

StarTalk Radio

Please continue.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

Charles, you take this one.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

Amazing.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

I haven't heard about the Scharnhorst effect being asked in a very long time.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

A scientist named Scharnhorst, I think it was around 1990 or so, hypothesized that if you took two perfectly smooth metal plates and brought them within a millimeter or a millionth of a millimeter within one another โ€“

You would create zones because of the quantum fluctuations of the universe where the index of refraction was less than one.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

What it practically means is that in those tiny zones that are only a fraction of an inch across, the speed of light could actually exceed the speed of light in vacuum.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

This would be a hypothetical.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

There's been no way to be able to test it, and the effect is tiny.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

So it would be one trillionth of a trillionth of a trillionth of a percent faster than the speed of light in vacuum across this zone, which was less than a millionth of an inch across.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

So it's this really neat effect that if we could test it,

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

It would be neat to find.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

Unfortunately, we cannot create, at least as far as we know, if the Scharnhorst effect is true, these kinds of pumped spaces that our questioner is asking.

StarTalk Radio
Cosmic Queries โ€“ Spontaneous Symmetry Breaking with Charles Liu

Because the causality and the speed of light and the stuff like that at those micro levels cannot translate into a macro level thing like being able to draw energy from nothing.
