Question

Can we find a unified theory of physics?​

Answer 1

Answer:

In physics, forces can be described by fields that mediate interactions between separate objects. ... In the mid-19th century James Clerk Maxwell formulated the first field theory in his theory of electromagnetism.

But unfortunately, it was not true. Few of Einstein's colleagues were impressed by this work. And within a couple of years, even Einstein accepted that his approach was deeply flawed. If Einstein was going to find a viable unified field theory, he would have to find another way of approaching the problem.
