Hilbert Space
Named for its putative inventor, mathematician David Hilbert (who some claim found the solutions for Einstein's equations before "L'il Albie" did himself), Hilbert Space is a concept which has been often applied in mathematics, quantum mechanics, and in general metaphysics (for instance, concepts like "parallel universes"). In short, a Hilbert Space is a mathematical construct such that within any plenum of n-dimensional spaces there exists an infinite number of said Hilbert Spaces (subsumed within an n+1 dimensional superset). Fancifully, science fiction writers point to the infinite plurality of 4D Hilbert Spaces that could exist within our "normal" 5D continuum, and suggest that each such Hilbert Space may really exist and that these Hilbert Spaces could be engendered by time-travel to the past. Thus, each 4D Hilbert Space in a 5D superset of "Universes" could possess a unique history, entirely different from all other universes contained within the 5D "Universe".
The Urban Dictionary Mug

Loved this mug! So unique and you can edit the text to add something unique.
I gave it to my friend who took money from me and never returned.
I love the fact that I was able to customize my name since I've never been able to find anything with my name. The only downside is it's smaller than I thought it would be (I guess I didn't pay much attention to that), wish it was bigger, only about 10 oz total.
It's simply awesome; and plus, the word means a lot.
Really fast and looks great! Took a chance on Christmas gift and it was a success!
Awesome mug feels really nice good weight and color although I think the shade could be a little brighter when it comes to the highlighter yellow, I am still pleased with the outcome and the fact that a whole passage was so neatly printed onto the product, very pleased with the packaging too! That made it so easy to wrap just in time for Christmas. Who knew!!
okay so the mug was mid but when you have a genz meme and give it to one of the most serious people you know then it's pretty funny
Nice mug, great feel‼️
Perfect!
Good quality ceramic cup! Worth the novelty price!

Perfect gift for my gf
Looks great! Came quick
Gave it to my nerd brother. He used it consume liquid

Love it

as a fan of non-Z-generation-UD (since 2000 more or less) , especially of old-school definitions ("phat!") (as Nick, the more time passes by, the more I reach my inner age = 75 XD) , I totally appreciated the delivery in time for Christmas! (whispering) Perhaps printing quality in the Spain printing company is not as good as in the US, but - hey! - I got it before Christmas as a gift for my thank-God-non-Gen-Z-sister! ;) hugs from the eighties, and from Italy, and thanks!

This is SO cool. Morning coffee will always memorialize my new addition to the English lexicon.

Too inappropriate
Item came at appropriate time in good condition.
epic
Got exactly what I wanted. Very happy with my mug.
