ring singularity
Also known as a "rotating uncharged blackhole" or a "Kerr blackhole". One of the four possible solutions to Einstien's field equations for general relativity. Unlike a standard blackhole, which has a single point singularity, a ring singularity is ring shaped because the blackhole is rotating. Any object that has spin and collapses into a blackhole would turn into a ring singularity. Ring singularities are known to be of special interest because of the unusual phenomenons that occur near the singularity, that would not occur at a single point singularity. The structure of the rotating blackhole is different. In a rotating blackhole, the outer layer is called the ergoshpere, which is shaped like a ovaloid. There are also two event horizons, the outer event horizon is taurus shaped. The outer event horizon acts like that of the event horizon found in a non-rotating blackhole. However the inner event horizon is different. Inside the inner event horizon space and time start acting normal again. The real interesting part is about the ring singularity at the center. The edges of the ring singularity act like a singularity found in any non-rotating blackhole. However the central region inside of the ring according to physicists acts like either a portal to another universe, a wormhole, or both. Majority if not all blackholes in the universe have a ring singularity. This is because all objects in the universe have some amount spin, including stars that collapse into a blackhole.
The Urban Dictionary Mug
The price was a little expensive, but the gift arrived as ordered. Thanks!
Great mug got one for my highschool crush
I was very pleased with the mug and I was thrilled that I could purchase a customized item that perfectly suited the person I was gifting. The only issue I had was that it didn't have the quote from the tv show the word came from as that was pictured on the mug prior to purchase.
Came out just as described! Had the full definition. Very pleased!
Perfect gift As a joke I gave one to my mate but I costumised it. It said tom drunk 24/7 ugly and got lovely hair. The lovely hair part was a joke coz he don’t have any. It was his favourite gift he got for his birthday and he drinks his beer out of it 😂

Great mug… got one for my girlfriend… instant sex
As always, these are well made mugs that stand up to most anything. And they make perfect gifts (in this case for dirty-minded members of a wedding party). I’m extremely pleased.
Is a great mug that I purchased as a gag gift for a coworker. You know the one who also as interesting words/phrases that only urban dictionary can explain. Great as a coffee mug and better as conversation piece!
👍

The mug exceeded my expectations. Really excellent quality and build
Jim, you’re a fucking idiot interfering with accurate ratings and legitimate feedback. Get a hobby.
Great gift!
A little spendy, but worth it.
My wife kept talking about "ways out" being a Denver version of "psych" and she was right, so I got her this once I found it on UD. She loved it!
