I have decided to rescind this model because it is not logically consistent, the great gap was between the field equation and equations of motion. I completely accept that scalar gravity models as…

Recent Planck spacecraft observations of the Cosmic Microwave Background (CMB) – the fading glow of the Big Bang – have highlighted a discrepancy between cosmological results and  predictions…

In the 'sometimes what you don't find can be important too' department, a new high-accuracy calibration of the LUX (Large Underground Xenon) dark matter detector's sensitivity to ultra-low…

I believe I am not alone in being fascinated by the ongoing debates about this or that physics experiment being on the verge of destroying the Earth. Microscopic black holes produced by mistake in…

The ATLAS collaboration at the Large Hadron Collider, CERN's 8-TeV proton-proton collider now being recommissioned to run at the close-to-design energy of 13 TeV in 2015, has published a few days ago…

A new paper by Davison Soper and Michael Spannowsky has been sent to the Cornell preprint ArXiv last week. It proposes a new technique to reconstruct the decay of heavy particles within hadronic jets…

Yesterday I visited a high school in Treviso, a small centre in north-west Italy. The students of the last two years participate in a program called "masterclasses" which includes lessons on particle…

First principles are calculations that rely on established mathematical laws of nature without additional assumptions or special models. But when it comes to the early universe, what are those first…

On January 25th 1996 the CDF collaboration submitted for publication to Physical Review Letters  the result of their measurement of the rate of jet production as a function of jet transverse…

Black holes are all the rage these days, with theorists arguing about firewalls and Hawking's paper being handled by the press in rather improper ways. Meanwhile at the Large Hadron Collider ATLAS…
