The most advanced version of the cosmic string theory. M-theory exists in eleven-dimentional hyperspace, where two-branes and five-branes can exist. There are five ways in which M-Theory can be reduced down to ten dimensions, thereby giving us the five known superstring theories, which are now revealed to be the same theory.
The full equations governing M-theory are totally unknown.

Get the M-Theory mug.
To manifest a dream into reality. M theory relates to the concept of the overall string theory and quantum mechanics. The M Theory was derived by Ed Witten in 1995 and stands for Magic or Matrix or according to test! It affliliates quantum mechanics with the workings of thought verses action.

In golf, a hole in one is the perfect use of M Theory.
Jerry: I'm going to make a space ship and fly to the closest star!

Watson: How on earth can you do that?

Jerry: Easy, M Theory! Its elementry my dear Watson.

Get the M THEORY mug.
A theory states that any girl that starts with an M is not worth any of your time. She will break your heart and probably take your money.
You know that girl you were dating a while back? M____?

Yeah, what a fucking bitch bro.

Seriously, M Name Theory bruh.

Get the M Name Theory mug.
Potential partners who have a name starting with the letter “M” are likely to to be attractive, funny, and kind. Current science is limited but it’s believed they have an enzyme that is generated in their system that called the builtdifferentezine that allows for this condition to take shape. It’s often suggested one pursues a date of some kind or the contact information of an “M” specimen to further investigate this unusual condition.
Oh his name is Marcelese? Here’s my number, give it to him and tell him I want to grab coffee sometime! I need to test the M Theory
