Get Ready .. The CBSE Class XII Results are coming

CBSE announced that the CBSE Class XII results will get started to publish from 21 May 2016. Though CBSE is trying to publish the Class 12 results of all regions together on 21st, there may be some regions not completed the result related works. However all the regions will publish the results shortly, starting from tomorrow.


Wish you all candidates the very best!!!


There Is Something Very Wrong With Particle Physics – CERN

Latest CERN Results Indicate There Is Something Very Wrong With Particle Physics

The Standard Model puts all the known subatomic particles into a single theory. There are six quarks (up, down, charm, strange, top, bottom), six leptons (electrons, muons, tau, and their corresponding neutrinos), the force carrier particles (gluons, photons, Z and W bosons) and the Higgs boson.

The latest results from CERN indicate that we might be on the verge of new physics.

The predictions based on standard model for a special particle called a B meson doesn’t match what has been seen in the experiment.

A particle that doesn’t fit the laws of physics – CERN

Researchers could be very close to finding a FIFTH  fundamental force. Results from the Large Hadron Collider hint at a particle that doesn’t fit the laws of physics. The new particle is believed to be SIX times heavier than the Higgs boson particle.

Further testing is required which is why more ‘collisions’ will commence next month in order to obtain new data. Scientists believe they will have either the ultimate confirmation or refutation of its existence by summer of 2016.

Professor John Ellis, theoretical physicist at Kings College London told the Mail Online in an interview: ‘it would be something completely beyond the Standard Model, and the tip of an iceberg of a large new set of particles if it exists.’

Two of the detectors, ATLAS and CMS, were used to look for new physics and did so by counting ‘particle decays’ that ended up in TWO photons

Problem with Einstein’s Theory of Relativity

Einstein’s theory of relativity was beyond any doubt lovely, different from any other theory ever imagined by mankind. Newton described gravity merely as a force acting over a distance attracting any 2 masses, the force proportional to the product of the two masses and inversely proportional to the square of the distance between them. This simple straight forward theory worked well for over two hundred years.

The theory is deceptively simple. First, there is no “absolute” frame of reference. Every time you measure an object’s velocity, or its momentum, or how it experiences time, it’s always in relation to something else. Second, the speed of light is the same no matter who measures it or how fast the person measuring it is going. Third, nothing can go faster than light.
