A New Theory of Everything That Sets Scalars Equal To Tensors Looks Like Nonsense.

If your theory of everything has tensors set equal to scalars then it is wrong. Simply put...

Satoshi Kanazawa has caused a firestorm by asserting that African women are less attractive than other races women. For this he has been called racist. He actually didn’t say anything new, or for that matter scientifically incorrect. However politically incorrect and insensitively stated it was. The man is guilty of being so stepped in his scientific ivory tower that he forgot how what he says may affect real people in the world. That said the conclusions of such work no matter how disturbing and un PC must not be grounds for a scientist in any field to lose his or her job.
The big bang was given it's name by Fred Hoyle, in order to make the theory sound absurd.  He metaphorically called it an explosion.   In the mist of time most people even some scientist lost the metaphor part of that and thought of it as an explosion.  Others then stopped using the metaphor because it confused people.   
This is more of an entry about the use of language than physics.  That said here is the shortest possible argument for why the big bang was not an explosion for anyone who needs convincing:

Explosions are the free expansion of material from higher, pressure, temperature and density to lower pressure, temperature and density in a short amount of time. 
Really?  Seriously  according to OK Cupid's analysis of their data from asking 642533 people the question  5% of men (gay and straight) and 10% of women (gay and straight) think the Earth is bigger than the Sun.  This finding is in a posting by Ok Cupids researchers about gay Vs straight sex. 
99942Apophis A asteroid which if it were to hit earth would hit off the coast of California and do damage similar to the Earthquake. A 9.0 magnitude earthquake is equal to about 450 megatons of TNT being set off underground.  Due to the situation at the Daiichi nuclear plant near in Sendai Japan there is much talk of how nuclear plants should not be built in earthquake zones.
Where can one see the lunar eclipse online or at a viewing party.  Here are a couple of options and how to find out.

The best option would be to watch the eclipse online via NASA's live feed of the eclipse from Huntsville Alabama. Which I have embedded right here. 



Here I will explain the difference between matter, anti matter, dark matter, and negative matter in a concise and understandable way.   I have seen confusion pop up in various online forums and comments on the recent announced trapping of an anti atom by CERN. 

The first thing to know is that for a physicist there are four fundamental forces of nature which are always at work.  These are the familiar Gravity and  Electromagnetism, as well as the generally unfamiliar strong and weak atomic forces.   The atomic forces work on the length scale of atoms, Electromagnetism and gravity work on the length scale of the universe though in fundamentally different ways.
