Physicists Discover an Unexpected Force Acting on Nanoparticles in a Vacuum
Nanoparticles can be pushed by pure nothingness.
Researchers have discovered a new and unexpected force that acts on nanoparticles in a vacuum, allowing them to be pushed around by pure ‘nothingness’.

Looks interesting, but I wish they wouldn’t call a vacuum “pure nothingness”.
Because only God is pure?

No, because a vacuum is full of whatever is left when you remove the air from a region of space filled with air, which certainly isn’t nothing.

Which the article says itself, right under the headline.

Is it an absence of somethingness?

So a vacuum is a like an Aero bar

Only if you limit “something” to those things that are not included in the things that make up a vacuum.

> To figure out how else Casimir forces could impact nanoparticles, the team looked at what happened with nanoparticles rotating near a flat surface in a vacuum. What they found was that the Casimir effect could actually push those nanoparticles laterally – even if they weren’t touching the surface.
Is this theory or experiment? If experiment, how did they stop the beams used for observations from influencing the motion?
(Check abstract)
“Working within the framework of fluctuational electrodynamics, we derive analytical expressions for the lateral force and analyze its dependence on the geometrical and material properties of the system.”
Oh, so theoretical only. Pity.
