In the early part of the 21st century, Myron Evans developed a new unified field theory which he called the Einstein Cartan Evans theory (ECE theory). The ECE theory showed the flaw in Einstein's theory of General Relativity. Not only can spacetime be curved to create gravity, it also spins to create all the electromagnetic effects. In fact ECE theory demonstrates that all physical phenomena can be explained with 4 dimensional geometry that includes spin and torsion and is a truly unified theory that unifies quantum mechanics, electromagnetism and gravitation. The ECE theory is explained at length at websites like www.aias.us and www.upitec.org
