"THE BIG BANG"
THE ORIGINS OF MATTER, ENERGY, SPACE, AND TIME
13.798 billion years ago

Some 13.798 billion years ago, our universe (matter, energy, space, and time) came into existence. Exactly how and why this happened is not really understood. It is believed that all of the matter that now exists in the universe was originally compressed into a point smaller than the size an atom called a singularity, which rapidly expanded. This expansion, first faster than the speed of light, has been dubbed "The Big Bang." The matter of the universe first consisted of a superhot plasma from which the first subatomic particles formed. As the universe expanded, in its first few minutes, it began to cool, forming the first primeval atoms: hydrogen, helium, and lithium.

Less than one-thousandth of a second after the Big Bang, two types of particles formed: matter (which our universe is composed of) and antimatter. These particles, called "quarks" (the matter) and "antiquarks" (the antimatter), met and annihilated each other. It is believed that there was a slight asymmetry or imbalance in the number of each type of particle, with matter very slightly outnumbering antimatter by about one particle per billion. Our resultant universe is composed of that slight surplus of matter versus antimatter. These quarks, in groups of three, formed protons and neutrons, the major components of atoms.

The "afterglow" of the Big Bang event has been measured in the form of the cosmic microwave background radiation, which records the basic temperatures that permeated the very early universe, averaging about 2.7 Kelvin (Celsius) above absolute zero as seen today (it would have looked a lot hotter back then, about 3000 degrees, before the expansion of the universe) . About one % of the static on your television (when not on a station) comes from this ancient cosmic radiation from about 13.4 billion years ago.

 

 


HOW DO WE KNOW?

Experimental subatomic particle colliders attempt to recreate the high-energy, high temperature conditions that existed in the universe a split-second after the "Big Bang". This allows us to look at the subatomic world of particle physics, and to examine the primordial particles and forces that make up matter and energy. On another scale, astronomical studies of distant galaxies show that they are all retreating from each other at an ever-accelerating rate, pointing back to a single origin (the singularity) of the entire universe. Observations of a certain class of exploding stars have allowed us to calibrate the rate of expansion, suggesting an age of 13.798 billion years for the Big Bang.

We do not know, however, what forces are driving and accelerating this universe expansion. Mysterious terms such as "dark matter" and "dark energy" have been used to denote these unknown and as yet undetected forms of matter and energy.

WHY SHOULD I CARE?

The Universe's first fireworks. An image of the area of the universe containing the Ursa Major constellation taken with NASA's Spitzer Space Telescope, but with light from stars, galaxies and other sources removed. The background light remaining (brighter objects seen in white and yellow, dimmer objects in darker colors) is from a universe that is still very young, less than a billion years old, when it contained very early objects such as huge stars or black holes.

We are talking about the origins of all matter‚ every atom of your body, every atom of the air we breathe, the food we eat, the water we drink, not to mention every atom of the earth, the solar system, the galaxy, and the universe. Exactly how and why this happened is one of the great mysteries of science and metaphysics.

Interestingly, the term "Big Bang" was first coined in 1949 by astronomer Fred Hoyle who did not believe in the concept, and used the term to ridicule the theory. Hoyle believed the universe existed in a "steady state" form, with no beginning or end. As time went on, more and more studies supported a definite, singular origin for the universe from which all matter expanded, and the term "Big Bang" stuck.
