The 2024 Legal Defense Fundraiser has ended early due to the Board's decision to settle the suit. Donations will go towards the creation of a legal defense fund. Discussion on the matter can be found at the RationalMedia Foundation noticeboard. Thank you for your generous support.

Virtual particles could use some help. Please research the article's assertions. Whatever is credible should be sourced, and what is not should be removed.

Virtual particles are particles described by quantum physics that exist for an extremely limited space and time. The term virtual should not confuse you into thinking that these particles do not exist. They really do exist, interacting with other particles, producing a measurable effect on their surroundings.[1] The very laws of physics prevent them from ever actually being directly seen or measured.

Virtual particles do have mass, even when they are part of massless forms, such as photons.

How?

The vacuum of space (or, more correctly any "space") has an energy level. Nothingness is in fact something.[2] Due to the uncertainty principle, virtual particles will always appear from the energy of a vacuum and always appear in pairs. These particles "borrow" energy from the vacuum and immediately collide and annihilate themselves, repaying the energy back into the vacuum and thereby do not violate the laws of thermodynamics. This process has implications for the development and eventual dissipation of black holes; when a virtual pair appears next to the event horizon of a black hole, one particle may fall in and if that happens the other will free itself. In order to maintain the first law of thermodynamics (energy cannot be created or destroyed) the black hole must then give up a little of its own energy to repay the lost energy - this is called "Hawking radiation."

Why they matter to non-physicists

If a RationalTypePerson™ is ever out walking along the beach, minding his own damn business, and a loonie fundie creationist comes up to him, to try to convince our rational thinker of the very "irrational" position he holds in regards to his "faith" in the "religion" of "Darwinism", the Fundie type will almost always, at some point in the argument, arrive at this comment: "Evolution does not work because of the Laws of thermodynamics".

Now such fundie will rarely understand what they are saying, they are just touting off a line as it was touted off to them, probably by the likes of Ken Ham or Kent Hovind. The fundie will not really explain his position, he will just shout out "Violates Second Law".

The wise and thoughtful Rationalist will shout back "Virtual Particles".

Virtual Particles, by all accounts of modern quantum physics, do exist. They can, in fact, appear and disappear, literally be self-created and self-destroyed in an instant, inside of a vacuum. In that sense, these very real particles are one of several very obvious violations of the "Law" (which is really a model anyhow) of Thermodynamics.
