we have unified field Theory which actually started with early attempts by Albert Einstein to unify general relativity which described his theory describing the force of gravity and electromagnetism there were only two forces of nature known at the time then uh eventually physicist found that there are two other forces the weak and strong the nuclear forces uh subatomic forces and we have now the standard model which describes three out of four known forces of nature electromagnetic weak and strong with spectacular experimental success but of course a lot of questions remain for it has a lran of
standard model has something like 19 parameters a lot of people not satisfied with it they feel that there are much deeper theories have to be discovered right
