The only thing funny about the 21th Dec and happenings is

But this is normal experimental and scientific behaviour, nothing to worry here, I guess .... .

An experiment can't go on forever, at one time you get to the part where things happen and produce data.

Its just a coincidence, because of christmas being on monday this year .... .

In either case, I'll be in Geneva that day, very nice area btw.

I will be on top of CERN, LOL, literally.

I'll let you know if there are any "vibrations".

Will they be colliding any particles on the 21st ?

Thats what he experiments are all about. ??

In fact only by colliding particles other particles are created.

no.

"Alongside their best known use in particle physics as colliders (e.g. LHC, RHIC, Tevatron), particle accelerators are used in a large variety of applications, including particle therapy for oncological purposes, and as synchrotron light sources for fields such as condensed matter physics.

Because colliders can give evidence on the structure of the subatomic world, accelerators were commonly referred to as atom smashers in the 20th century.[3] "

"CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research - as a result, numerous experiments have been constructed at CERN following international collaborations."

CERN scientific achievements:

Several important achievements in particle physics have been made during experiments at CERN.
They include:

1973: The discovery of neutral currents in the Gargamelle bubble chamber.[3]

1983: The discovery of W and Z bosons in the UA1 and UA2 experiments.[4]

1989: The determination of the number of light neutrino families at the Large Electron–Positron Collider (LEP) operating on the Z boson peak.

1995: The first creation of antihydrogen atoms in the PS210 experiment.[5]

1999: The discovery of direct CP violation in the NA48 experiment.[6]

2010: The isolation of 38 atoms of antihydrogen[7]

2011: Maintaining antihydrogen for over 15 minutes[8]

2012: A boson with mass around 125 GeV consistent with long-sought Higgs boson.[9]

After friday 21th CERN will shut down, for maintenance reason, ...

it will shut down the accelerators for 2 years. Its because of the magnetic fields. They need to get strenghten up again.

Its like a big magnet, if it is used too much, they get weak.

Well, looks like CERN is too scientific for GLP, LOL.

See ya lata guys.

LOL.

Hey OP, Christmas is on Tuesday, unless France made some declaration to change it.

For me christmas is on monday, the 24th, church, presents in the evening, and an nice dinner.

In France it is on tuesday, thats true.

But I am no french :-).
