If I'm reading this right, does this mean that classical physicists were right about the ether all along?

No, for several reasons. One is that ZPE does not establish an absolute frame of reference (which was the primay reason for assumming the existence of an ether.) Another is that an "ether" in which "things" exist and move is inherently a dualist model of reality, whereas modern physics is based on fundamental unification of forces, particles and geometry. Finally, ZPE is not a "medium" or "transport substrate" for wave propagation, which was the key characteristic of the hypothetical "ether."

This is a very impressive group. A collaboration of researchers from Cal Tech, MIT, Oak Ridge, Stanford, Princeton and others.

The California Institute for Physics and Astrophysics (CIPA) is dedicated to exploring fundamental problems in physics (e.g. gravitation, inertia, the nature of mass) as well as very-long range technological possibilities that may emerge from the properties of the quantum vacuum.

The propellor or the jet engine of an aircraft push air backwards to propel the aircraft forward. A ship or boat propellor does the same thing with water. On Earth there is always air or water available to push against.

Was this absurd statement really written by someone with a physics background?

How is this statement absurd? It seems perfectly true.

There's no point to it.

Go check your physics for "On Earth there is always air or water available to push against." This is a common misconception by the masses.

Um, so propellor-driven locomation would actually work in a perfect vacuum?

Where did you come up with that outrageous conclusion?

There's no point to it.

Ok. What's your point?

[sourcery]

Where did you come up with that outrageous conclusion?

It seemed to be the best interpretation of the point of your question. If that is not what you meant, perhaps you could clarify?

I was thinking the exact same thing as I read the article.

[ShadowAce]

If I recall some high-school physics (a VERY long time ago), planes move forward by a combination of the air being pushed rearward, but also by the partial vacuum created in front of the motor that results when the air is being pushed backwards.

I could be wrong, but that is what I remember from high school.

Go check your physics for "On Earth there is always air or water available to push against."

Just took a survey out the window, and it appears there is air out there and sometimes water. What is the problem, aside from earth should be lowercase?
