Einstein’s Unified Field Theory Realized? New Theory Unites Electromagnetism and Gravity Through Geometry

More than a century ago, Albert Einstein searched for a single theory that could describe two or more known interactions—electromagnetism, gravity, and the weak and strong forces—previously described in separate theories. The search for this “unified field theory” has ultimately been left unfinished. Now, a team of researchers says they have produced a purely geometric theory that can unite gravity and electromagnetism—two of nature’s fundamenta…
