In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics but not general relativity’s description of gravity. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles. (Wikipedia)
It is expected that future studies into continuum mechanics will lead to the abandoning of the ‘big bang theory’ and other related theories.
The big bang theory conflicts with the principle of sufficient reason. There is much more ground for the assumption that dense quantum fields are formed out of electromagnetic radiation that originates from the sun. This assumption is supported by the equation E=m.c2, an equation that originates from the work of Lorentz and Einstein.
Continuum mechanics leads to a better explanation of natural phenomena like ‘vacuum’ and ‘cavitation’. Also, buoyancy is better explained. And finally, it is the ruling principle behind the theory of conservation of matter (mass).
The physical properties of quantum fields are highly dependent on what is called the state of excitement. The state of excitement of dense matter is related to its relative heat content. These elastic properties of matter are widely used by mechanical engineers for the generation of force.
