A few nice tattoo images I found:

"A twist in the fabric of space where time becomes a loop"
This is the Mobius Tattoo. A scientific calculation that can be used in Astrophysics to describe a closed system if gravity is strong enough to bend spacetime into a loop. Basically meaning that if you travel far enough, you will end up where you began without really knowing it.
This is my first Tattoo and it turned out great. This is on the inside of my Right Bicep. I will be adding another space or scientific tattoo to my other bicep next year. And yes… certain parts of the Tattoo process hurt like a son of a gun…Look at the note to where it hurt a lot. 🙂
