The electromagnetic force and the weak force have been unified by theoretical physicists into something called the electroweak force.
Q. What is unification in physics class 11?
Unification: It is the act of unifying the different laws valid for different phenomena in to a single theory that explains all the different phenomena. Eg. Electricity, magnetism and light are different phenomena and have different laws of physics for each of them.

Q. What is force unification?
The unification of forces is the idea that it’s possible to view all of nature’s forces as manifestations of one single, all-encompassing force. Today, scientists seek to unify this with the strong force—without which the nucleus of an atom wouldn’t hold together—under a Grand Unified Theory.
Q. What efforts have been made towards unification of forces?
According to the theory of quantum electrodynamics (QED), the most successful relativistic quantum field theory, the photon is the carrier of the electromagnetic force. Grand unified theories (GUTs) attempt to reconcile three of the four known forces: electromagnetism, the strong force, and the weak force.
Q. What was the last thing Albert Einstein said?
Albert Einstein’s last words will never be known. He spoke them in German, but the attending nurse didn’t speak German and so couldn’t recall what was said. He died in his sleep at a hospital in Princeton, New Jersey on April 18, 1955, leaving the Generalized Theory of Gravitation unsolved.
Q. Is everything a field?
Carroll’s stunner, at least to many non-scientists, is this: Every particle is actually a field. The universe is full of fields, and what we think of as particles are just excitations of those fields, like waves in an ocean. An electron, for example, is just an excitation of an electron field.
Q. What holds all matter together?
Gravity is the force that all objects with mass exert upon one another, pulling the objects closer together. The tiny particles that make up matter, such as atoms and subatomic particles, also exert forces on one another. These forces are not gravity, but special forces that only these particles use.
Q. Are particles made of waves?
Through the work of Max Planck, Albert Einstein, Louis de Broglie, Arthur Compton, Niels Bohr, and many others, current scientific theory holds that all particles exhibit a wave nature and vice versa. For macroscopic particles, because of their extremely short wavelengths, wave properties usually cannot be detected.
