The Quote Of The Week- Dark Matter Stopped Before Reaching Us

"In the case where the dark matter particle is light (less than 1 GeV) and the interactions is either contact or mediated by light (but not massless) particles, there is parameter phase space that cannot be probed by current underground detectors eve ...

DZERO: The Top Quark Mass Is 1.6 GeV Higher Than You Guys Say

Very recently, a combination of the precise measurements of the mass of the top quark obtained by the CDF and DZERO experiments at the Fermilab Tevatron collider with those produced by the ATLAS and CMS experiments at the CERN LHC collider has been produce ...

Why Energy Seems Quantized Especially To Crackpots

I receive much crackpot email. There is a very common misunderstanding often central, one I have not seen a good answer to anywhere. This is partially due to that few who write about physics counter crackpot theories well. Allow me to explain this point w ...

Tricking The Uncertainty Principle- Going Beyond The Standard Quantum Limit

"Subatomic particles act in quantum ways—they have a wave-like nature—and so can atoms, and so can whole molecules since they're collections of atoms," Schwab says. "So the question then is: Can you make bigger and bigger objects behav ...

The Action of General Relativity

In this blog, I will review my thoughts on the action of general relativity, how it is used for the field equations and equations of motion.  There is much to consider, so perhaps this will create a means for discussing this deep subject. The Action ...

A New Hypothesis About A Theory: The 80-Year Quest To Turn Light Into Matter

Physicists say they have discovered how to create matter from light- a feat thought impossible when the idea was first theorized 80 years ago. There is just one problem. In order to test the newest hypothesis, a new& machine would have to be built. In ...

ATLAS Challenges You: Can You Discover The Higgs?

I came to know through a social network (I have many colleagues as friends there, and they usually post more useful stuff than cute kittens) that ATLAS has launched a very intriguing competition. One you can participate to, if you have some programming ski ...

I Just Ate Your Earth-Like Planet

Some Sun-like stars are 'earth-eaters.' During their development they ingest large amounts of the rocky material from which 'terrestrial' planets like Earth, Mars and Venus are made. Trey Mack, a graduate student in astronomy at Vander ...

Anomalous Whew: Particles Near Absolute Zero Don't Break The Laws Of Physics After All

The laws of physics are absolute- in theory.  And with an exception. So absolute doesn't always mean what we think it means. How heat and temperature related to energy, the laws of thermodynamics, seem to violate the laws of physics theoretically. But ...
