If mass is considered to bend space time fabric..
does electric charge bends anything?

well many people believe this but why not space ime fabricdavenn said:and there is no space-time fabric![]()

thats the thingDrakkith said:Davenn means that 'fabric' is a misleading word. A fabric is usually thought of as a 2-dimensional object (or very thin 3-dimensional). However spacetime is 4-dimensional, with 3 dimensions of space and 1 of time. The diagram of a sheet being bend downwards by a massive objects is a 2-dimensional analogue of what is really going on. Unfortunately it's just really, really hard to visualize the curvature of a 4-D manifold.![]()
roger larouche said:I can't think of any force , no matter it's origin or it's composition ; would not have any effect on matter in it's path or in it's surrounding.
Drakkith said:The strong nuclear force does not interact with electrons, even if they pass through the nucleus of an atom.
roger larouche said:The definition of a force do not have any value without resistance in it's path or in it's surrounding ~~ and ''Energy has the same definition''
Magnetic force, for instance, has no effect on plastic or glass.roger larouche said:I can't think of any force, no matter its origin or its composition ; would not have any effect on matter in its path or in its surrounding.

David Lewis said:Magnetic force, for instance, has no effect on plastic or glass.
roger larouche said:A force cannot be created nor calculated at it's value ; if it's ''opponent'' ( plastic ) do not offer any resistance
As force involves acceleration, something has to be accelerated, which does not want to. It's usually called Newton's first law, and not "resistance". La résistance was a Belgian and French movement against the German occupation during WWII.roger larouche said:Yes~Forces only exist as a result of an interaction. witch mean; +++ resistance more forces.
