Beam of Protons Warms Up LHC













(The first ion beam entering point 2 of the LHC, just before the ALICE detector October 23rd 2009)

This past weekend (October 23-25th) particles once again entered the LHC after the one-year break that followed the incident of September 2008.

Friday afternoon a first beam of ions entered the LHC's clockwise beam pipe through the TI2 transfer line. The beam was successfully guided through the ALICE detector until point 3 where it was dumped.

During the late evening on Friday, the first beam of protons also entered the LHC's clockwise ring and travelled until point 3. Saturday afternoon (October 24th), protons travelled from the SPS through the TI8 transfer line and the LHCb experiment, until point 7 where they were dumped.

All settings and parameters showed a perfect functioning of the machine, which is preparing for its first circulating beam in the coming weeks.

Halo Cloud Explained













A strange halo cloud over Moscow had many in the Russian capital expecting a close encounter last Wednesday.

Millions witnessed an ominous ring-shaped cloud appear over Moscow’s western districts, prompting citizens to stop in their tracks to record the phenomenon and put it on YouTube.

The bizarre sight has taken the Internet by storm, so to speak.

However, scientists from the city’s weather forecast service dispelled fears of extra terrestrials landing in Red Square, saying the event was strictly environmental.

“It’s a purely optical effect, even if a spectacular one. You can see really strange things if you watch the clouds regularly,” weather officials told Russia’s Vesti 24. “Several air fronts have passed Moscow recently, including an inflow of cold air from the Arctic, and they combined to produce such a phenomenon

Indeed halo clouds have appeared elsewhere in the world, a notable example being the 'Dorset Doughnut' seen over Dorset, UK and captured in various images by the Cloud Appreciation Society.

Influence from Future in Large Hadron Collider












For those that can no longer access the NYtimes article. Here is a link to the arxiv article:

Search for Effect of Influence from Future in Large Hadron Collider

We propose an experiment which consists of drawing a card and using it to decide restrictions on the running of Large Hadron Collider (LHC for short) at CERN, such as luminosity, and beam energy. There may potentially occur total shut down. The purpose of such an experiment is to search for influence from the future, that is, backward causation. Since LHC will produce particles of a mathematically new type of fundamental scalars, i.e., the Higgs particles, there is potentially a chance to find unseen effects, such as on influence going from future to past, which we suggest in the present paper.
