What would make a perfect sphere perfect???

Question

Answer 1

Hi tom science

The most perfect sphere in nature is the event horizon surface of a non-rotating uncharged black hole. This most simplest form of black hole is called a schwarzschild black hole, and the event horizon the schwarzschild surface. Basically any non-spherical protusion on the surface would necessarily be radiated away during formation of the hole, leaving a perfectly spherical geometrical surface as the horizon (at least from the perspective of an observer at infinity in the geometry - as you fall towards the hole that geometry starts to change a bit).

So in this case what makes the schwarzschild surface a perfect sphere is the irresistable strength of gravity at this scale. The fact that gravitational forces are proportional to r^2 means that the least potential surface is always a sphere.


Hope this helps!

Answer 2

Every point on the sphere would have to be the exact same distance from the center.

That's it. No god here.

(although the only perfect sphere exists in "mathworld" ie the only perfect sphere is one defined mathematically; ie. x^2 + y^2 +z^2 = k, where k is whateveryoulike.)

Answer 3

GOD.
A sphere is only perfect in theory, in actual life absolute perfection is unattainable.
GOD is the only one that could perfect a sphere where pi would be exact..

Answer 4

I find it hard to believe that a perfect sphere exists, outside of mathmatics. I think this is mainly becuase any large body has a number of small imperfections and, alternatively, any small body has has a particular uncertainty associated with it (uncertainty principle).

Answer 5

Every point on its surface is exactly the same distance from its center.

Answer 6

look up the definition of pi
