## The world’s roundest object made of sillicon, becomes the new definition of a “KILOGRAM”. Check out the history of “KILOGRAM”.

Check out the video if you have ever used a “kilogram” to measure something.

The “reference kilogram” is a lump of metal in France, the kilo being the only metric measurement not based on some objective standard. A project is underway to replace the kilo with something independently reproducible: perfectly spherical balls of based on Carbon-12. Incidentally, these new kilos would also be “the roundest objects in the world.”

This is brilliant. Fabrication of a Silicon Sphere By definition, an Avogadro number of Carbon-12 atoms weigh exactly 12 grams. As such, the kilogram could be defined as the mass of 1000/12 * Avogadro’s number of Carbon-12 atoms. The Avogadro constant itself is obtained from the ratio of the molar mass to the mass of an atom. For a crystalline structure such as silicon, the atomic volume is obtained from the lattice parameter and the number of atoms per unit cell. The atomic mass is then the product of the volume and density.

## “DARK MATTER” WHAT’S THAT?

Galaxies in our universe seem to be achieving an impossible feat. They are rotating with such speed that the gravity generated by their observable matter could not possibly hold them together; they should have torn themselves apart long ago. The same is true of galaxies in clusters, which leads scientists to believe that something we cannot see is at work. They think something we have yet to detect directly is giving these galaxies extra mass, generating the extra gravity they need to stay intact. This strange and unknown matter was called “dark matter” since it is not visible.

The darkmatter cannot be seen unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter. The astonishing fact is that the matter we know and that makes up all stars and galaxies only accounts for 4% of the content of the universe! But what is dark matter? One idea is that it could contain “supersymmetric particles” – hypothesized particles that are partners to those already known in the Standard Model. Experiments at the Large Hadron Collider (LHC) may provide more direct clues about dark matter. Dark energy makes up approximately 70% of the universe and appears to be associated with the vacuum in space. It is distributed evenly throughout the universe, not only in space but also in time – in other words, its effect is not diluted as the universe expands. The even distribution means that dark energy does not have any local gravitational effects, but rather a global effect on the universe as a whole. This leads to a repulsive force, which tends to accelerate the expansion of the universe. The rate of expansion and its acceleration can be measured by observations based on the Hubble law. These measurements, together with other scientific data, have confirmed the existence of dark energy and provide an estimate of just how much of this mysterious substance exists.

## What’s a “Blackhole”? what if we move closer to it?

This is one of the greatest informatic videos i have ever watched.

Blackhole is nothing but an empty space, it is a great amount of matter packed into a very small area – think of a star ten times more massive than the Sun squeezed into a sphere approximately. The result is a gravitational field so strong that nothing, not even light, can escape.

Scientists can’t directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself. As the attracted matter accelerates and heats up, it emits x-rays that radiate into space.

If we move close to EVENT HORIZON to escape from the gravitational pull of blackhole we need to move with the speed of light which is not possible, also the strong gravitation pull slow downs the Time. If we see this from earth it seems like taking thousands of years to complete because of the Light. So as we move still closer we experience SPAGHETTIFICATION, a Singularity with ‘0’ volume and infinite gravity.

Recent discoveries offer some evidence that black holes have a dramatic influence on the neighborhoods around them – emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.

Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.) If the total mass of the star is large enough (about three times the mass of the Sun), it can be proven theoretically that no force can keep the star from collapsing under the influence of gravity. However, as the star collapses, a strange thing occurs. As the surface of the star nears an imaginary surface called the “event horizon”,TIME ON THE STARS SLOWS RELATIVELY TO THE TIME KEPT BY OBSERVER FAR AWAY . When the surface reaches the event horizon, TIME STANDS STILL, and the star can collapse no more – it is a frozen collapsing object.

## CERN researchers confirm existence of the Force/ DIRECTLY TAKEN FROM “CERN WEBSITE”

Researchers at the Large Hadron Collider just recently started testing the accelerator for running at the higher energy of 13 TeV, and already they have found new insights into the fundamental structure of the universe. Though four fundamental forces  – the strong force, the weak force, the electromagnetic force and gravity – have been well documented and confirmed in experiments over the years, CERN announced today the first unequivocal evidence for the Force. “Very impressive, this result is,” said a diminutive green spokesperson for the laboratory.

“The Force is what gives a particle physicist his powers,” said CERN theorist Ben Kenobi of the University of Mos Eisley, Tatooine. “It’s an energy field created by all living things. It surrounds us; and penetrates us; it binds the galaxy together.”

Though researchers are as yet unsure what exactly causes the Force, students and professors at the laboratory have already started to harness its power. Practical applications so far include long-distance communication, influencing minds, and lifting heavy things out of swamps.

Kenobi says he first started teaching the ways of the Force to a young lady who was having trouble revising for her particle-physics exams. “She said that I was her only hope,” says Kenobi. “So I just kinda took it from there. I designed an experiment to detect the Force, and passed on my knowledge.”

Kenobi’s seminal paper “May the Force be with EU” – a strong argument that his experiment should be built in Europe – persuaded the CERN Council to finance the installation of dozens of new R2 units for the CERN data centre*. These plucky little droids are helping physicists to cope with the flood of data from the laboratory’s latest experiment, the Thermodynamic Injection Energy (TIE) detector, recently installed at the LHC.

“We’re very pleased with this new addition to CERN’s accelerator complex,” said data analyst Luke Daniels of human-cyborg relations. “The TIE detector has provided us with plenty of action, and what’s more it makes a really cool sound when the beams shoot out of it.”

But the research community is divided over the discovery. Dark-matter researcher Dave Vader was unimpressed, breathing heavily in disgust throughout the press conference announcing the results, and dismissing the cosmological implications of the Force with the quip “Asteroids do not concern me”.

Rumours are growing that this rogue researcher hopes to delve into the Dark Side of the Standard Model, and could even build his own research station some day. With the academic community split, many are tempted by Vader’s invitations to study the Dark Side, especially researchers working with red lasers, and anyone really with an evil streak who looks good in dark robes.

“We hope to continue to study the Force, and perhaps use it to open doors with our minds and fly around and stuff,” said TIE experimentalist Fan Buoi. “Right now, to be honest, I don’t really care how it works. The theory department have some crackpot idea about life forms called midi-chlorians, but frankly I think that poorly thought out explanations like that just detract from how cool the Force really is.”

With the research ongoing, many at CERN are already predicting that the Force will awaken later this year.
