The Quantum Vacuum

by Bob Leon

1st June 2017

How did something come from nothing and where did the material for the Big Bang come from? Many cultures have created various myths to try to answer these questions.

Modern day physicists and cosmologists have ideas in keeping with theory and observation eg. quantum mechanics and relativity theory which at times can be counter intuitive and controversial. Another theory is a Dirac matter anti-matter. This is a model of vacuum as an inifinite sea of particles which go in and out of existence. Another effect is the known as the Casimir effect where two plates in a vacuum are pushed together because of virtual waves outside the plates and the greater pressure is between the plates.

The two main stays of physics are quantum mechanics and general relativity and attempts have been made to link them without much success so far. Quantum mechanics predicts that if something is not forbidden then it must happen. It is also possible that many other Universes exist whose physics may be very different from our own.
