Oh wait @bolbteppa just posted that formula. Silly me.

You could only use $\gamma^\rho\gamma^\mu = -\gamma^\mu\gamma^\rho$ if the anticommutator were zero

Division by zero algebra Theorem 1: Given any algebraic structure $(S,\cdot,+)$ such that $\cdot$ left distribute over $+$ and the underlying set $S$ arbitrary, and that there exists a left or right multiplicative inverse to a left or right additive identity, the addition structure must have the following form:

2

Proof:
For all $x \in S$
$0+x=x$
Multiply both sides by the zero inverse on the left
$q0+qx=qx \implies 1+qx=qx$
Since $q$ is injective by definition of an inverse $X = qS \subseteq S$. By the above equation, all elements of $X$ dominates 1 on the right.
Now multiply both sides with some $y \in S$
$y1+y(qx)=y(qx)$
The morphisms $y\cdot$ can be injective, surjective, bijective or neither, thus $y(qS) \subseteq qS$
Now, note that the term on the RHS dominates $y$. Repeat the above argument, we end up with a linearly ordered decreasing chain of subsets of $qS$ that is the images after multiply…

Details on the multiplication structure still to be worked out, but 00=0 is a known no go condition

Proof involve running through 4 cases involving left inverse and right inverse

Any further investigation is not sustainable with PhD progress thus will be posponded until the PhD is completed

@0celo7 I thought about what you said and you've got a point. I think, a triple major is the way to go.

Math, Physics and Chemistry. With those, you have the universe's secrets at your fingertips when you graduate

@SirCumference you’re insane dude

that’s totally a bad ideA

the only thing you’ll have when you graduate is the realization that you don’t know shit about any of them and that your areas of study were to broad to learn anything related research in any single one of them.

13 bucks for a GR book!

It's only 20 pages but still

A piece of history

John Rennie

Advanced Stidues :-)

Slereah

the best kind

although from the look of things, I suspect this may be one of those books

you know the kind

cheap cover with xeroxed pages inside

Stop talking to yourself as a robot, @Secret, it's very annoying.

"It is one of the little ironies of our times that while the layman was being indoctrinated with the stereotypic image of black holes as the ultimate cookie monsters, the professionals have been swinging round to the almost directly opposing view that black holes, like growing old, are really not so bad when you consider the alternative."

"The worry is illustrated in Fig. 3.1 where all sorts of nasty things - TV sets showing Nixon's "Checkers speech", green slime, Japanese horror movie monsters, etc. - emerge helter-skelter from the singularity."

The worst possible scenario

"In Fig. 3.5b the black hole is even blacker because even those unfortunate observers who fall into the hole cannot 'see' the singularity, though they may well feel and, indeed, may be torn apart by the tidal forces as they are inevitably sucked into the singularity. Nevertheless, they may take some cold comfort in the fact that SCC holds."

John Rennie

@Slereah as I recall there is an apparent horizon that recedes before the infalling observer, so the observer sees only a horizon retreating from them. They only reach the horizon at the moment they hit the singularity.

Slereah

it's a rough ride

"Of course, the statement that no singularity exists will be hotly disputed by the ghosts of the observers who have been sucked into the black hole and have been snuffed out after only a finite existence (as measured by their respective proper times)."

Every sentence of that book is great
