可以用粒子傳任何力?

In fact, we guest that the 4 basic forces are transmitted by particles.
The EM (electromagnetic) force is transmitted by photon (EM radiation, simply, light).
The gravitation force is suggested transmitted by griviton, by theory, it is very hard to find out griviton.
The strong and weak force are transmitted by photon type particles, but I forgot its name.

It is not 可以用任何粒子傳送任何力, it is the 4 basic forces MUST be transmitted by particles.

Since all forces are the result of the 4 basic forces, say if you pull a block by a rope.Macroscopically the force is transmiited by you through the rope to the block.

While in microscopic, the force you use are come from the contraction of muscles, which is comes from the chemical energy of molecules, and this is the change of the bonding of atoms and so on.

Same case can use on the rope, the force is transmitted through the molecules of the rope, which is the bonding of molecules, finally it is the EM forces.

So you can say the all forces are transmitted by particles, but the paticals are transmitted in varied distance.

Thay are usually very short ranged.
