Directions (Q. 1-15): Read the following passage carefully and answer the questions given below it. Certain words/phrases have been printed in bold to help you locate them while answering some of the questions.
“Thanks, Nature.” Two little words marked the end of the speech of Fabiola Gianotti, the spokesperson of the ATLAS experiment, indicating the collective sigh of relief at what is believed to be the beginning of the end of the longest, and most expensive, search in the history of science.The discovery of the Higgs particle will lead to a new understanding of the origin of matter in the Universe, which occurred in the smallest fraction of a second after its creation 13.4 billion years ago. Indeed, it is the key to understanding the existence of diversity and life in the Universe.Physicists believe that the Higgs particle has been spotted at the world’s largest and most expensive laboratory— 27 km in circumference, 100 m below ground, straddling the border of France and Switzerland. The Large Hadron Collider, a multi-billion-dollar array of machines, is run by a pan-European organisation called CERN in Geneva. This is where, among other things, the World Wide Web was invented. Now it is the scene of another ground-breaking event. The world has been waiting for over 40 years since professor Peter Higgs, currently at the University of Edinburgh, UK, predicted the existence of Higgs particle. In recent years, “Higgs Rumors” has been one of the most popular hashtags on Twitter.
According to the standard theory, at the moment of the creation of the Universe, all particles were massless, and they all travelled at the speed of light. A trillionth of a second after the birth of the Universe, an all-pervading invisible field switched on, that caused particles to acquire mass. This is known as the “Higgs field”, and its only visible manifestation is the Higgs boson.When I run on a track, I am at my fastest, but if I try to run on sand, or in water, I won’t be able to get up to the same speed, even though I might exert the same energy. It is the medium, like air, sand or water, that holds me back. If a bunch of particles is given the same amount of energy, the more massive particles travel sluggishly, and the lighter particles travel at higher speeds. The only exception is the photon, the particles that make up light. Even in the Higgs field, the photon acquires no mass, and thus can travel at the maximum possible speed allowed by nature, which is… you’ve guessed it… the speed of light.Inside the Large Hadron Collider, particles like protons were being accelerated to near-light speeds, and hurled at each other in the dark underground tunnels, colliding in a flash of energy, as electrons, quarks, and other more massive particles emerge. If our theories are correct, a few of these particles, including the new particle announced on July 4, will be Higgs particles. It is not clear how many kinds of particles make up the Higgs field. Various instruments that line the walls of the tunnel will help piece together the complicated jigsaw of what actually happened in the collision. The experiment will run till the end of this year, and it will take a decade for scientists to analyse the data to look for and confirm the detections of possible Higgs particles.
The Higgs boson was named the “God particle” by the Nobel-winning US physicist, Leon Lederman, since it is all-pervading and omnipresent. Scientists often use the word “God” when they borrow one of the divine characteristics attributed by various religions. Apart from understanding the nature of matter, such fundamental discoveries open up fields of research that are hard to imagine at the time. For instance, when the electron was discovered at the dawn of the 20th century, nobody imagined how today our life would be dominated by electronic devices. Only time will tell what the Higgs will lead us to. Of the 6,000 scientists involved in the experiments, many are Indians, belonging to, among others, the Saha Institute of Nuclear Physics in Kolkata and the Tata Institute of Fundamental Research in Mumbai. There is a deeper connection with India. All elementary particles are divided into two kinds, fermions and bosons. The Higgs particle is a boson, named after the Indian physicist Satyendranath Bose, who, along with Albert Einstein, first described its nature, almost a century ago.
