Casimir Effect Debunked

You might have heard about the Casimir Effect whose popular explanation would have you believe in “Six Impossible Things Before Breakfast.”

Casimir Effect advocates claim that a force is generated from absolutely nothing (!)
More specifically they allege it comes from the “Vacuum Energy” of an electromagnetic field.

Its experimental definition admits it only “works” with “two uncharged conductive plates in a vacuum.“

Tiny Clue: This means Casimir Effect does Not Work with (fairly obviously uncharged) Ceramic Plates !

That’s Problem #1. If the explained effect is independent of electromagnetic effects, just requiring an ultra-slim slice of vacuum between two plates, then it should make no difference if we test it with metal or ceramic plates.

Problem #2. On the superficial level of humans “uncharged conductive plates” seems reasonable.

On our macroscopic level, a metal plate may not exhibit a charge. A metal surface has a gigantic number of outer electrons not bound to any one atom. Instead, they form an “electron sea” – generally at no charge. (“The farmer doesn’t charge to cross his field, but the Bull might.”)

But on a microscopic level – there is an atomic lattice with millions to bazillions (technical term) of metal atoms. However, no metal made so far with millions of atoms is perfectly pure. It always has impurities with other elements.

And at each impurity intersection with the non-metal there is a charge difference. Sometimes there’s a charge change from negative to positive – or vice versa.

If an impurity provides extra electrons that local intersection becomes slightly negative charged. And when an impurity removes electrons the local intersection becomes slightly positively charged.

So all of a sudden the physical experiment contradicts its theoretical definition. Its no longer composed of “uncharged conductive plates.” Meaning it is really not possible to conduct (pardon me) the experiment with full control over all variables. And since any Casimir Effect is so excruciatingly, vanishingly tiny, its reality evaporates back into Alice’s Adventures through the Looking Glass.

Here’s a more technical article explaining (Spoiler Alert) the true origin of the Casimir force is van der Waals force. A force which both attracts and repels.

Notably, “Casimir’s original goal was to compute the van der Waals force between polarizable molecules” of the conductive plates. So it can be interpreted without any reference to the zero-point energy (vacuum energy) of quantum fields.

“Proof that Casimir force does not originate from vacuum energy”
