Panius Why does a singularity have to have mass? TreBert

Well, TreBert, it does depend upon what kind of
singularity we talk about...

http://en.wikipedia.org/wiki/Singularity

(Most of those don't have mass.)

The one talked about here in a.a is usually the
"gravitational" singularity. And that is defined
as...

"a point in spacetime in which gravitational
forces cause matter to have an infinite density
and zero volume."

And "infinite density" tells me that a singularity
of this type must have mass, "infinite" mass.
It is this infinite mass that theoretically became
the universe after the "Big Bang" took place out
of just such a singularity. And frankly, that idea
sucks rocks, IMHO. The thought of a singularity
being the central point of origin of the Universe
makes me gag.

happy days and...
starry starry nights!
