Magnetism and gravitation

Try looking at the four physical forces

Magnetism is covered as an electromagnetic force, gravity is 'well' gravity and although the effects are covered by an inverse square relationship, electromagnetism is 10^36 times as strong as gravity. In addition electromagnetism is a polar force having a attraction and repulsion effect, whereas gravity is only an attraction.

So although there is a similarity in the effect of both these forces, they are in no way similar.

look up the governing equations of the resultant forces of each and compare. Did your teacher not tell you to do that? Make a chart of the similarities in the equations and that helps you understand.

Thanks fm. How could I have gone through life without knowing that? No wonder I never understood anything.

I understand definitions of gravity and magnetism. What I don't understand is where did come from the energy that magnet imprint ball with, repeatedly.

True

Of the four forces - although electromagnetism (don't forget the electrical part) appears on the surface most similar in outcome to gravity, they operationally appear miles apart. It's a lot more than the E/M is an extremely strong force whilst gravity is extremely weak. The E/M, nuclear strong and weak have clearly understood carriers and a working model for how they normally interact above an atomic level.

Gravity on the other hand Einstein postulated is more like an attribute of space-time itself (i.e. its curvature) than a force moving through it; space tells matter how to move and matter tells space how to warp. So this means gravity should be thought of not as regular force with force carriers (e.g. Higgs Bosons or Higgs Boson in a Higgs field) moving through a space-time field but rather an intrinsic property of the field itself.

So at its simplest gravity is a one step more abstract force than manifest weakly but very importantly in our perception of reality. At its most complex gravity hints at the underlying structure or reality itself and one model of reality is multiple, dimensionally different overlapping universes (a Multiverse) with gravity being the sole "force" that can cross between otherwise separate universes.

It all gets horribly complex fast - but basically theoretical models say consider space time as 10 dimensional (not 3) and the extra dimensions are hidden - possibly in very extraordinarily small dimensions but geometry of these dimensions is at least as important as the forces moving through them in determining how the universe actually works!

Nice. Like in Jet Lee's movie "The One". Only remain one unsolved problem: what's happen when only one remain. The one become a kind of god or the universe will collapse???
Tough question ha?
Maybe hollywood will solve it in a following movie.
