Neutrinos and Light-speed – some skeptical thoughts

I’m sure you are by now all familiar with the news, but just in case not, lets start with quick summary. An Italian experiment has unveiled evidence that fundamental particles known as neutrinos can travel faster than light. This comes from an experiment that is called OPERA (Oscillation Project with Emulsion-tRacking Apparatus), and lies 1,400 … Read more

Punching a Hole in Time

This latest item of science news leaves me wondering just how much of it is hype and how much is real, so I’m pushing it out into a couple of skeptic communities to see what folks think. Here is the claim …

First Demonstration of Time Cloaking

Physicists have created a “hole in time” using the temporal equivalent of an invisibility cloak.

(BBC) Antimatter Tevatron mystery gains ground

US particle physicists are inching closer to determining why the Universe exists in its current form, made overwhelmingly of matter.

Physics suggests equal amounts of matter and antimatter should have been made in the Big Bang.

In 2010, researchers at the Tevatron accelerator claimed preliminary results showing a small excess of matter over antimatter as particles decayed.

The team has submitted a paper showing those results are on a firmer footing.

Each of the fundamental particles known has an antimatter cousin, with identical properties but opposite electric charge.

Neutrino Transformation Could Help Explain Mystery of Matter

Cool story in Wired today … Two research teams have found new evidence of transformations in elusive elementary particles called neutrinos. The findings may finally help explain why the universe didn’t vanish shortly after its birth. “These results are just the beginning of the story for neutrinos,” said physicist Robert Plunkett of Fermilab in Chicago. … Read more

Signs of dark matter from Minnesota mine

Ron Cowen reports in ScienceNews that there are Possible evidence for WIMPs reported, supporting claims of Italy-based experiment

An experiment in Minnesota is the first to bolster a long-contested claim that detectors a continent away have found evidence of particles called WIMPs.

WIMPs are theorized particles considered to be leading candidates for dark matter, invisible material believed to make up more than 80 percent of the matter in the universe.  In the Minnesota experiment, called COGENT, a hockey puck–sized chunk of germanium deep in a former iron mine attempts to record rare collisions with WIMPS.

Moores law just keeps rolling on … Graphene is the new platform

Moores law is not an actual law, it is instead the well known observation, made by Intel co-founder Gordon E. Moore in 1965, that the number of transistors that can be placed inexpensively on an integrated circuit will double approximately every two years. In fact, when he first made this observation, he was simply predicting … Read more
