What is Unified Field Theory?
Name: Ulises A.
Please explain to me, in layman terms, what the Unified
Field Theory is about? Thank you.
Hi, Ulises A. !!!
Well, in layman terms - and that is all I can also do - , you know
that there are four forces in the universe :
1 - gravity forces
2 - electromagnetic forces
3 - forces that maintain the proton together in the nucleus of atoms (strong force)
4 - forces related to the breakdown of atomic nucleus - radioactivity - (weak force)
Can you imagine another type of force, different from these ??
Many scientists are trying to unify all these fields in only one theory, and probably
they will do it in the future. The mathematics involved is very complicated.
Einstein took a precious role in this field and - through his theory - he could
develop some concepts like the warping of space-time to explain the gravity force.
For sure you know the idea of a heavy ball on the surface of a body made up of
The strong force holds the nucleus together, although the nucleus consist of
protons with strong repulsive electrical charge. James Clerk Maxwell formulated
the first field theory in his theory of ELECTROMAGNETISM. Later, Einstein
developed the general relativity, a field theory of GRAVITY. Later on,n Einstein
focused his attention on an unified field theory, but it was an impossible ntask for him.
Since then, the gravity remains beyond any attempts of unification.
Nowadays, new theories have been developed, that invoke quarks, leptons, etc,
and field symetrie. We have to wait a little more...
