Particular question we have been asked which fundamental force of nature is the most difficult to include in the unified pure theory or ufti so first of all let us define ufti so unified pure theory tells means is an idea that everything every fundamental force right so let me define this theory first every fundamental force has the same origin every fundamental force can be described from a common origin.
00:41
From a common origin.
00:43
So this is a very lame and description of unified field theory.
00:47
So i'm keeping it simple for you so that we can understand what the question is asking.
00:54
So we have four fundamental forces, right? four fundamental forces in the nature.
01:00
So let me define all those first.
01:02
So first one is your electromagnetic force.
01:07
Right so it is electromagnetic force the second one is gravitational force the second one is gravitational force the third one is strong nuclear force right we can we generally are tell that it is strong force right we generally do not uh mention nuclear but it is eventually strong nuclear force and we have weak nuclear force or in general we tell that it is weak force.
01:40
So we have four fundamental forces in nature and every fundamental force has been, it has been an attempt to unify every fundamental force so that we can have a unified field theory that describes the origin of all the forces.
01:57
Now here there is one force that we are finding the most difficult to include in our unified field theory.
02:07
Now what is that force? right.
02:09
So that is gravitational force.
02:12
Now why gravitational force is such a it a we are facing such difficulty in incorporating gravitational force in our uft? now the answer to this comes from the nature of two theories...
