Gravity and magnetism
What are the definitions of both forces as we know today? Can a rotating
galaxy create a magnetosphere? Can gravity and magnetism work together and hold a galaxy together? Is dark energy real or just a type of magnetism/gravity thing? Cursing and sick replies unwanted. Thanks for scientific replies. |

Gravity and magnetism
Dear A J K:
On Apr 9, 1:32 pm, "A J K" wrote: What are the definitions of both forces as we know today? magnetism: the curvature of spacetime due to "net charge motion". gravitation: the curvature of spacetime due to the presence of mass. Can a rotating galaxy create a magnetosphere? I don't see why not. Can gravity and magnetism work together and hold a galaxy together? Magnetism is unlikely in the long term. Charge imbalance sufficient to assist in a temporary "grip" will rapidly disperse. Is dark energy real or just a type of magnetism / gravity thing? It describes observations that we make. "Real" or not remains to be seen. http://www.astro.ucla.edu/~wright/cosmo_04.htm .... down to the last paragraph http://www.jb.man.ac.uk/mru2007/rationale.html http://courses.washington.edu/phys55...plain%20It.htm David A.
