CMS construction at Point 5: current status from Camera 1The current time at Point 5 is: Thursday, 15h34Wednesday, 15h24 - this page will reload every 5 minutes
This image shows the free space in the hall with YB-1 on the righ and YB0 on the left. HB- has been inserted inside YB0 and prestressed against HB+. Concrete towers have been erected to survey mapper rails being installed inside HBs. HB+ cradle is being moved near main shaft PX56.
If you'd like to know where the cameras are physically positioned, take a look here.

A SEMMI ÖRVÉNyÉBEN
Newton: absolute space AND absolute timeMach,Leibnitz: relational to all other objects, üres térben nincs gyorsulás,tömegEinstein: spec.rel-ben absolute space-time ált.rel –ben acceleration is relational to gravitation: spacetime is A something
Before QM and Higgs:They specified the benchmark for defining accelerations
Higgs Ocean = Asymmetric solution for symmetic theoryHiggs-field condenses at 10**15 K (10**-11 sec) NO mass before
NOW we know: WHY objects resist accelerations????
A VÁKUUM ANYAGA
A természetes rádióaktivitás felfedezése óta nem fedeztünk fel semmiféle új anyagfajtát
- sugárzás: He atommag kvarkokból
- sugárzás: Elektron nyaláb
- sugárzás: Foton nyaláb
HIGGS-BOZON tölti ki az egész teret
Az üres atom
Az atommagban pontszerű kvarkok vannak, de pontosan mérhető a sugara.
Mennyi a valami?
Az elektron pontszerű részecske: az elektronhéj az üres(!!)
Az atom és mag sugarának aránya: 1OO OOO.
A valami aránya a semmihez: O.OOO OOO OOO OOO OO1.

Nem sok ez egy kicsit???? Mengyelejevnek elég volt 66 elem.
It describes all fundamental particles of our Universe
As far as we know them at present …
They are controlled by UNIVERSAL laws of physics …
There are (at least) 26 constants of Nature
12 masses, 3 coupling strengths, 11 mixing parameters
Some of these are left – right asymmetric !
And we know that this theory is incomplete …
Why is the universe constructed with this range of seemingly random numbers?
Why do the elementary particles have just the right properties to allownuclear process to happen, stars to light up, planets to form around stars, and on at least one such planet, life to exist?
In string theory, particle properties are determined by string vibrational patterns.

Fact 3) The combined strands of the superconducting cable being produced for the LHC
would go around the equator 6.8 times. If you added all the filaments of the strands together they would stretch to the sun and back 5 times with enough left over for a few
trips to the moon.
Fact 6) The ATLAS cavern could hold the nave of Notre Dam cathedral.
Fact 7) When the 27km long circular tunnel at CERN was excavated, between lake Geneva and the Jura mountain range, the two ends met up with just one centimetre of
error.
Fact 10) The Large Hadron Collider at CERN could be the most ambitious scientific undertaking ever. The results of LHC experiments will probably change our fundamental
knowledge of the universe.
Fact 16) CERN is the world's largest laboratory dedicated to the pursuit of fundamental science.
Fact 21) If the Higgs boson exists the LHC will be able to make this particle detectable. Confirming or contradicting the first evidence of the Higgs particle is an exciting
prospect!
Fact 29) The Grid is a service for sharing computer power and data storage capability over the Internet. Its ultimate aim is to turn the global network of computers into one vast
computational resource.
Fact 30) Verification of the theory that explains why the sun shines – the weak force - is one of CERN’s biggest achievements.
Fact 31) The discovery of the neutral current was announced at CERN in 1973. The theory was finally confirmed in 1983 with the direct observation of W and Z particles.
.
Fact 41) In 2003, 6.1% of traffic at Geneva International Airport was related to CERN, a total of 54 868 passengers.
Understanding all of the different forces of nature within one framework is one of the
ultimate goals of physics. Decades of experiments at CERN are working towards this.
99.999999999999% of an atom’s volume is empty space. If the proton were a pea, the electron would be in the back of the strands at Old Trafford.
When protons arrive in the LHC they are travelling at 0.999997828 times the speed of
light. Each proton goes around the 27km ring over 11 000 times a second.
The proton beam of the LHC will have an energy equivalent to a person in a Subaru driving at 16 000mph.

Dark MATTER
In order to have approximately flat universe now, some mechanism must havetuned the matter-energy density of the early universe extraordinary close to the critical density. Inflation cures the original curvature.
proton-neutron matter less than 5 %Zwicky 193O something holds back distant fast-moving galaxies. Detailed studiesgives the same problems for stars inside galaxies.Nonluminous matter 25% is required.
Candidates: netrino less than 1%, axions?WIMPs Weakly Interacting Massive Particles from big bang SUSY:photino,zino,higgsino...etc.
Dark energy
Accelrating expansion of the universe
Type Ia supernova distance – recessional speed light yield – doppler effect
The observed size of acceleration requires 7O % plus energy by cosmological constant. New survey satelite SNAPSuperNova/Acceleration Probe
This amount is the same what is reiquired for flat universe!!COBE, WMAP confirm flatness
