How do photon, gluons, w and z bosons, and gravitons mediate?
Thx.

He asked for "english". I am afraid that the meaning of uncertainty and energy do not coincide with the usual field of meaning of the same words in English.
Skhandelwal said:Although, this time, I understood what you told me..it just made me more confused. How can massless particles carry energy?
Skhandelwal said:I guess you are right, I have a mental block here. But then how do we define matter? I used to think anything that has mass or energy is matter. Anything else is vacuum.
Sean Torrebadel said:There are some, rare, few, who don't believe that particles play catch... I believe it was Newton who first suggested that forces at a distance, through empty space, was ridiculous-and the first to admit that he had no idea. What makes any of us think that we are smarter than Newton? In other words, Newton vocated a medium. How particles passing through space, therein causing two bodies to come closer together, could have ever been proposed- is clear evidence that our intellect is decaying.
Sean Torrebadel said:Do photons have mass? I believe that the answer is 'undecided'. And this is why I related my interpretation of the different schools-ending with a hypothetical idea, since the matter remains hypothetical, unproven, and often controversial.
Attraction/repulsion is a concept in physics that describes the forces between two objects. Attraction refers to the force that brings two objects together, while repulsion refers to the force that pushes two objects apart.
Attraction/repulsion is caused by the interaction of electromagnetic forces between the particles that make up the objects. These forces can be attractive or repulsive depending on the charges of the particles involved.
Attraction/repulsion can affect the movement of objects by either pulling them closer together or pushing them farther apart. This can result in changes in speed, direction, and trajectory of the objects.
Attraction/repulsion can be measured using the force of gravity or the Coulomb's law, which calculates the strength of the electromagnetic force between two charged objects.
Some examples of attraction/repulsion in everyday life include the attraction between the north and south poles of magnets, the repulsion between two positively or two negatively charged objects, and the gravitational attraction between the Earth and objects on its surface.
