Even though Einstein did not manage to develop a Unified Field Theory, other researchers have already started their search for a perfect blend between String theory and Grand Unified Theories. In addition to this, the new theories have succeeded in accounting for Quantum Mechanics as well.
Did Einstein try to develop a Unified Field Theory?
The answer is yes! Back in 193, the scientist made public a set of papers aiming to provide in-depth information into the “affine connection” that was implemented by Eddington. Later that year, he decided to publish a second study that argued the possibility to restore determinism to quantum physics. Unfortunately, back then, the other scientists did not fully understand Einstein’s theory, and every bit of its research went down the drain.
8Seven years later, he was still working on his Unified Field Theory, working at the same time with five-dimensional theories. The work continued for two more decades, including a wide number of ideas, but none of them included the laws of quantum mechanics.
Years have passed by, and researchers have managed to get closer and closer to a Unified Field Theory. While Einstein’s research mainly focused on gravity and electromagnetism, other physicists included the weak and strong nuclear forces. Strong nuclear force deals with holding the neutrons and the protons together, while weak nuclear force influences the radioactive delays.
What researchers are looking for is to discover a theory that defines the quantum mechanical nature of the world. The most accurate theories that have been identified until now include the string theory, where fundamental objects have a much more extended shape and present one-dimensional strings.
Even though, in reality, the newly rising theories do not have that much in common with Einstein’s discoveries, the researchers are still attempting to answer the same questions.
