I am biologist and just new to the field of quantum mechanics and trying to understand the subject by reading. It is said that virtual particles are created due to the uncertainty of energy when ...

And if that is the case, can an infinite amount of it be created? Does this mean that the potential energy or the energy that can potentially be created is infinite?

Do virtual particles take energy from the fabric space and when they annihilate in the split second they distribute that energy back to space, therefore abiding by the law for the conservation of ...

I have heard several pseudoscientific explanations about the Heisenberg Uncertainty Principle and find them hard to believe. As a mathematician mainly focusing on functional analysis, I have a ...

I have heard virtual particles pop in and out of existence all the time, most notable being the pairs that pop out beside black holes and while one gets pulled away. But wouldn't this actually violate ...

What actually are virtual particles? In various places around physics SE, documentaries and occasional news headlines, I see the term "virtual particles", normally virtual photons. I have tried ...

I am reading the book of Lawrence Krauss "A universe out of nothing", where he explained that the vacuum is not empty. It is a boiling brew of virtual particles that come out of their existence. And ...

When spontaneous electron / positron pairs annihilate, do they emit photons? If so, does this not negate the first law of thermodynamics?

Background Knowledge Researching on light led me to wave-particle duality and its properties regarding photons. All the sources I have seen agree that the frequency of the wave nature defines how we ...

Edit: my question is not directly about Feynman diagram, but instead about the nature of off shell objects, were they as common as the on shell ones. I am trying to suggest that if an electron goes ...

I was reading an answer in this exchange trying to explain Hawking Radiation to non-physicists (like myself) An explanation of Hawking Radiation . It informed me that the whole "virtual particle ...

It is my understanding that virtual particles are those that are internal to a particular interaction. They do not fulfill the requirements of a freely-travelling particle (ie a plane wave) and as ...

I've read at several places that a static magnetic (and electric for that matter) field can be thought of as made by virtual photons, at least that's what I understood. Now, in Special Relativity we ...

I was under the impression that the "handedness" of a massive spin-1/2 particle refers to its chirality rather than its helicity. This answer, this one and Srednicki's QFT textbook seem to use the ...

In Prob 1.2 of Griffith's "Introduction to Elementary Particles" 2nd ed., it says that: However, I don't understand why it states that "they must temporarily violate the conservation of energy by ...
