Inspire kids to become scientists by saying that…..……………………………………………………………………………………

Physics equations don’t need virtual particles.

…………………………………………

“Energy-time uncertainty relation” has nothing to do with virtual particles.

…………………………………………

In the absence of a non-perturbative formulation of quantum field theory,

we have to compute some amplitudes perturbatively (e.g. for outcomes of particle collisions) using Feynman diagrams imagined as virtual particles.

…………………………………………

Virtual particles are at least useful in the way pictures of chemical bonds are useful in chemical calculations, although from quantum-mechanical point of view these “bonds” are ephemeral.

…………………………………………

The semi-classical mixing of QFT and general relativity near the horizon of a black hole creates a virtual pair. One particle falls below the horizon, and the other acquires escape velocity producing Hawking radiation.

“Language alone protects us from the scariness of things with no names.”

……………………………………..

Foreign exchange market might work as an informal model to grasp a lattice gauge theory.

……………………………………..

Standard model needs gauge symmetries.

……………………………………..

Juan Maldacena’s space is a grid of countries and particles are travellers making money by speculating with currencies.

…………………………………………

To imagine the fundamental process that gives us magnets and keeps the lights on, kids need handy analogies not theories.

……………………………………..

Gravitational effects are negligible at the quantum level.

……………………………………..

General relativity and quantum mechanics can describe nature only within their domains of applicability.

……………………………………..

Since the gravitational field is a deformation of spacetime itself, gravity is supposed to act on particles interactions, or even on their existence.

……………………………………..

We still don’t know whether quantum field theory is stable if we take into account the gravitational field.

……………………………………..

Structures like black holes or cosmological singularities are the assumptions of general relativity, but their critical points, their subatomic singularities belong to the quantum realm. So physicists bother about such enigmatic structures to combine quantum mechanics with relativity.
