What is the smallest particle in the universe?

Many of you may be naive to believe that the smallest particle in the universe is the atom. Well, the atom is really considered the smallest indivisible particle until the discovery in 1897 by Joseph Thompson electron; proton, which was opened in 1920 by Ernest Rutherford, and in 1932 and the neutron, which was first discovered by the British physicist James Chadwick. After nearly 100 years, we know that everything in the universe is made up of quarks - the mysterious particles that are actively involved in gravitational and electromagnetic interactions. So what is a quark and what it looks like?

Quarks - the smallest particle in the universe

What is a quark?

Quark - the smallest particle of the universe. It consist of quark all electrons, neutrons and protons atoms, each of which was formed 13 billion years ago 7 immediately after the Big Bang. A few minutes after the birth of the universe, our universe could cool down so that they could form the first elementary particles - quarks and electrons. Quark joined with each other, forming the core atoms. After about 400,000 years the universe is able to cool down so much that there was a delay in the movement of electrons, allowing them to seize the atomic nuclei. In this way, all the visible and invisible space we could get the first atoms of hydrogen and helium, which, incidentally, are still the most common substance in the universe.

How are atomic particles?

The largest atomic particles are considered to protons and neutrons, which are slightly heavier than electrons and are located right in the center of the atom. The electrons form a lightweight cloud that rotates around an atomic nucleus. It is known that the weight of 1800 corresponds to one electron-proton heavyweight. In addition, the addition of at least one of a proton to an atom leads to the formation of new substances with different properties from the original, with the addition of an extra neutron creates only isotope of the substance or simply a more severe version of it.

As mentioned above, it is absolutely all the elementary particles composed of quarks. which represent a foundation of the universe. Interesting fact: The name "quark" was taken in one of the novels of the famous in the XX century modernist writer James Joyce, which is an unusual word has decided to designate the sound from ducks.

James Joyce - writer, which has given the term "quarks"

Themselves subdivided into quark 6 so-called "flavors", each of which has its own characteristics, or "color." In addition, each of the six types of quarks, and has its own very original name. So, in addition to the bottom and top quark types, there are also strange, charmed, charming and top quark.

Of course, the "strangeness" or "charming" quarks are very different from our usual notions. In the same way as the concept of quark color actually has in mind is not their color, but the way the interactions of quarks and other micro-particles - gluons. Well, scientists fantasy can sometimes surprise.

In any case, the quarks represent a truly unique particles of which in all respects depends the existence of our universe in the form in which we know it. Perhaps the secret of occurrence of the Big Bang, and our comprehension of the fundamental laws of the universe is really dependent on one tiny grain of sand, which is thousands and thousands of times smaller than an atom.
