Question:
We know that there exist four forces in nature which are:strong nuclear forces,
electromagnetic force,weak nuclear force and gravitational force.
NOW is it possible to unify these forces into "single basic force" which is the most fundamental
force and from which all other forces of nature are derived?
Replies:
Ahmed,
It is simple to join electromagnetic force and weak force: they are the same force. There is
one difference. What we call weak force involves the generation of a heavy particle, W+, W-, or
Z. All force between this particle and the other particles involved in the reaction is purely
electromagnetic. As for strong force, that may or may not be the same. It uses a different
kind of charge. Electric charge has two varieties, positive and negative. The charge involved
in strong force has three varieties. Since vision is based on a set of three colors, scientists
decided to call it color: red, green and blue are the names for the three charge varieties.
Since strong force is interaction of a set of charges, it may or may not be considered linked
with the electroweak force. Gravity is
still a problem. A positive charge combined with a negative charge makes a neutral charge. A
combination of red, green, and blue charge can also create a neutral object. Gravity is based
on mass, and scientists do not know how to make a neutral mass. In many ways, gravity has
properties that do not agree with the other forces. One involves light. Gravity actually
exerts a force on light. Gravity exerts a force on everything. The force varies from object to
object, but the acceleration is the same for everything. Albert Einstein tried to explain it
with his Theory of General Relativity. Scientists are still working on it.
