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
I like the mug, it’s good quality, unfortunately the customization wasn’t correct. I got the “juff” mug and instead of the definition i had a quote from one of my friends as a bit, but it just came with the definition. I’ll still give it to him because the joke still works but I am a little disappointed.
Love the fact that Urban dictionary came up with such an accurate and quick meaning for Binger! Mug was a little pricy but God is my morning coffee so much better in this mug!!
This mug is incredible! It was a great gift for my friend named Jacob, who is definitely gay. (Even though he says he isn't 🙄)

Great mug, she loved it
I'm in a Spanish-speaking practice group, and the phrase "Ajo y Agua" came up, meaning, (more or less) "If you f***ed up, deal with it." (It's a long story, how "Garlic and Water" means this, but that's the fun of it.) Anyway, the Urban Dictionary site with the mug popped up on Google (reading my mind, as always) so I bought one as a gift. It's not cheap as mugs go, but I'm happy to say the mug is VERY good quality, looks exactly as it does online, and is packed in the most securely designed mug-transport box I've ever seen. You can't break it in shipping or reshipping! Also it arrived in just a few days. I recommend this product highly.
i like mug that say words
I purchased the eggplant color cup for my friend, purple is her favorite color and she loves her special cup, she cooks a lot, so I had Itis with Iris put on one side of the cup and the meaning on the other side because when she cooks that how everyone feels afterwards!! Thanks UD Diana K.
Wanted to try these guys out to see if they delivered and how it'd go. Went great. Got two mugs within 7 days, unharmed, printed well. THANK YOU
I ate the mug it tastes good

I have a “gift” for plathering. The definition is right on. Can’t wait to have a cup of coffee across the table from my guy who will TOTALLY get it.
