Question

Can we find a unified theory of physics​

Answer 1

Physicists caution that a weakness of string theory is it has not yet been confirmed by data. There are also other approaches to unified field theory, such as quantum gravity, which tries to describe gravity in the terms of quantum mathematics

The handwritten page was part of Einstein's 1930 paper attempting to put together the unified field theory. An Albert Einstein "puzzle" has been solved thanks to a missing page of manuscript emerging in a collection of his writings acquired by Jerusalem's Hebrew University, officials announced Wednesday.

A theory of everything (TOE), final theory, ultimate theory, or master theory is a hypothetical, singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all physical aspects of the universe.Finding a TOE is one of the major unsolved problems in physics.String theory and M-theory have been proposed as theories of everything. Over the past few centuries, two theoretical frameworks have been developed that, together, most closely resemble a TOE.
