Why are Galaxies Flat?

December 31, 2012

GalaxiesThe question is nothing more than the difference between a sphere and a plain. When it comes to free matter, geometry is a property of strong and weak forces. On the grand scale, gravitational and inertial forces dictate shape.

Moving from the spheriosity of the central black hole to the planarity of the outer arms, galaxies seem to be a 3-D conundrum. It’s acknowledged that axial rotation overcomers gravitation; hence the shape of our solar systems and ringed planets.  True that planets bulge at their equatorial plane! But then why is the sun and planets flat?

The answer to why is probably a simple one! Could it be that galaxies are entirely spherical?  The visual limitation arises from the presence of unseen dark matter and dark energy.
