Raychaudhuri’s Equation in Cosmology

Yet another issue with the standard model: Renormalisation of divergencies

The Raychaudhuri’s Equation

 

The Raychaudhuri Equation is central to cosmology and one of the most famous equations known to a non-physicist, along with Mass-Energy Equivalence, the Ramanujam sum, the Einstein Field Equation, Euler’s formula, Euler’s identity, the Heisenberg Uncertainty Principle, The Schrodinger Equation, the Periwal divergency of String peturbation, the Standard Model Lagrangian Density, and the Dirac Equation. It was one of the most celebrated equations of the time.

 

The Raychaudhuri’s equation directly models the big bang, and star collapse among other things. It also can be used to prove that gravity is ALWAYS an attractive force in general relativity.

 

The elegance and simplicity of the Raychaudhuri Equation is just amazing… The Ricci Curvature Tensor operating on two vectors, that two, too which are 4-velocities… The magnitude of the shear tensor… The magnitude of the…EXPANSION TENSOR!!!… and the rate of expansion… ALL BROUGHT TO GETHER IN A 1 SINGLE EQUATION!!! That is just elegant. Very elegant!

Vegetarianism Part 12: From the Perspective of the Animal being killed+raised: Cruelty of Fur

My last animal rights post was written a loo…oong time ago. But now, since I have finished a major part of what I was doing in the Mathematics and Physics sections, General Relativity (ok, this not even half-completed yet) and Quantum Mechanics and Quantum Field Theory, I will finally write an Animal Rights Post, again. Note: That DOES NOT mean I will stop uploading the Mathematics and Physics videos. I still have to do videos on Raychaudhuri’s equation, Schwarzschild Metrics, Kerr Metrics, Reisnerr-Nordstorm  Metrics, Kerr-Newmann Metrics, Motivation behind GR…, many on Special Relativity, many on Hamiltonian and Lagrangian Mechanics,  many on Classical Mechanics, many on Maxwellian Electromagnetism, many on Newtonian Gravity, many on String theory, a few on LQG, many on criticising LQG, many on more basic calculus, etc. I also have to redo some (many,…( most, actually ) ) of my old math videos.

In this post, I’ll talk about the cruelty behind fur.

Many people fail to realise that fur coats and all other things made of fur are not made only out of the animal’s fur, but their entire skin. That means that the animal has to be killed, usually by skinning or something like that.

The animals whose fur is used are rabbits, chinchillas, foxes, dogs, cats, squirells, chipmunks, monkeys, apes (such as chimpanzees, and orang-gutans), bears, etc. They are caught from forests, etc. and kept in small filthy cages, all stacked upon one another, like the animals are “things”. Deaths often occur due to suffocation, hunger, thirst, or disease. Small animals such as rabbits, squirells and small cats are often kept in cages no bigger than a small little, average-sized drawer And there are perhaps 5 to 10 of them stuffed inside, stuck to the cages, almost. And 1 fur coat perhaps takes the lives of something like 200 rabbits or 50 foxes, or 500 chinchillas/squirellss.

When their fur is long enough and they are big enough, they are brought to the slaughterhouse of the fur farm. There, they are killed by one of the following means:

1. Upside-down Electrocution (usually for rabbits and foxes)

2. Throat-slitting and hanging upside-down to allow some of the blood to leak out. (for all animals)

3. Skinning (for all animals)

4. Head-chopping (for dogs and other large (bigger than a rabbit) animals, especially )

5. Pounding with a rock (especially for rabbits and other such small, little animals, such as squirells and small cats,)

Sorry, I had to put this  picture of a live rabbit skinned for fur:

Yet, some people wear fur to show off that they’re filthy rich murderous.

Issues with the Standard model; The Elegantly ugly theory

The standard model is elegant because  it’ is simple. It is ugly because it doesn’t explain anything. It is plain wrong because it doesn’t incorporate general relativity and thus it doesn’t have gravity in it. It is right because it explains Fermions, Gauge Bosons and Higgs correctly. But it doesn’t predict gravity! And it’s therefore PLAIN WRONG!
