Stephen Hawking's Universe

Stephen Hawking's Universe

It is theorized the nearby possibility of the existence of time travel with the help of black holes, wormholes and movements in light years. In this episode, it is an animation about the hidden existence of the quantum foam beyond the smallness of subatomic particles, and a reference to the grandfather paradox.

LHC Particle Collider

The Large Hadron Collider (English Large Hadron Collider or LHC, which stands for which is generally known) is a particle accelerator (or accelerator and particle collider) on the now called the European Organization for Nuclear Research (the acronym is of the old French name of this institution: Conseil Européen pour la Recherche Nucléaire, CERN) near Geneva in the French-Swiss border. The LHC is designed to collide beams of hadrons, more accurately proton energy of 7 TeV, its main purpose being to examine the validity and limits of the Standard Model, which is currently the theoretical framework of particle physics, which is known his break at energy levels high.


Theoretically it is expected that once operational, is detected particle called the Higgs boson (sometimes called "God particle"). The observation of this particle would confirm the predictions and "missing links" of the Standard Model of physics, being able to explain how other elementary particles acquire properties such as its mass.


Next to the Higgs boson could also cause other new particles that were predicted theoretically, and for which the search is planned, such as strangelets, micro black holes, magnetic monopoles and supersymmetric particles.


The new accelerator uses a tunnel of 27 km in circumference created for the Large Electron Positron (LEP in English) and November 30, 2009 became the most powerful particle accelerator at energies of 1.18 TeV get in their beams, surpassing the previous record, set by the U.S. Tevatron 0.98 TeV.

LHC Experiments:

Physicists hope that the LHC will provide answers to the following questions:
* The meaning of the dough (you know how to measure it but do not know what is really)
* The mass of the particles and their origin (in particular, if the Higgs boson)
* The origin of the mass of the baryons
* Total Number of particles of the atom
* To know why elementary particles have different masses (ie, if the particles interact with the Higgs field)
* 95% of the mass of the universe is not made of matter is known and is expected to know what is dark matter
* The existenciao no supersymmetric particle
* If there are extra dimensions, such as predicted by various models inspired by string theory, and, if so, why not have become apparent
* If more violations of symmetry between matter and antimatter

Alarms About Potential Disasters:

U.S. Ell Walter Wagner and Luis Sancho denounced the Spanish court of Hawaii at CERN and the U.S. government, claiming that it is possible to trigger its operation processes, as they would be able to bring about the destruction not only of the Earth but also the entire Universe. But his position is rejected by the scientific community, as it lacks any mathematical support to support it.

Catastrophic processes are reported:

* The formation of a stable black hole.
* The formation of supermassive foreign matter, as stable as ordinary matter.
* The formation of magnetic monopoles (under the theory of relativity) that could catalyze proton decay.
* Activation of the transition to a quantum vacuum state.


In this context, CERN has studied the possibility of the occurrence of disastrous events such as unstable black microholes, networks, or dysfunctions magnéticas.La conclusion from these studies is that "they are not founded bases that lead to these threats."

In summary:

* In the unlikely event that would create a black hole would be so infinitely small that it could travel through the earth without touching a single atom, since 95% of these are empty space. Because of this, could not grow and reach the space where your chance of hitting something and grow, it is even smaller.
* The planet Earth is exposed to natural phenomena similar or worse than those that will be produced at the LHC.


* Cosmic rays reach the Earth at speeds continuously (and therefore energy) huge, even by several orders of magnitude greater than those produced at the LHC.
* The Sun, due to their size, has received 10,000 times.
* Considering that all the stars of the visible universe are an equal number are reached about 1031 experiments like the LHC and not yet observed any event as postulated by Wagner and Sancho.


The production of strangelets in the LHC is less likely to RHIC, and experience in this accelerator has validated the argument that strangelets can not be produced.

Curiosity Zone:


* To control the primary configuration for machines of the LHC computer network using a scientific distribution of Linux called Scientific Linux. This network is used to receive and distribute the 15 petabytes of data to 100,000 CPUs worldwide.


* A group of Greek hackers managed to breach the security of Windows Server 2003 allowing entry into the server at CERN, to be "one step" of the systems that control the LHC. The group "Greek Security Team" left a message for the record that the system is vulnerable.
* The LHC launched its first particle on September 10, 2008. This fact had already circulated around the world, causing riots, and even the suicide of a teenage Hindu thought the world would end.


* It was expected that the LHC was officially launched in December 2008, but a helium leak caused it disconnected.


* Stephen Hawking bet $ 100 that the Higgs particle does not exist and said it would be more interesting not to find the so-called God particle.
