The Big Bang Astronomers combine mathematical models with observations to develop workable theories of how the Universe came to be. The mathematical underpinnings of the Big Bang theory include Albert Einstein's general theory of relativity along with standard theories of fundamental particles. One of the goals has long been to decide whether the Universe will expand forever, or whether it will someday stop, turn around, and collapse in a "Big Crunch? Then, as time went on, we would see the Universe cool, the neutrons either decaying into protons and electrons or combining with protons to make deuterium an isotope of hydrogen.
November 7, This information helps astronomers determine the age of the universe. ESA and the Planck Collaboration. The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models.
Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.
While the majority of the astronomical community accepts the theory, there are some theorists who have alternative explanations besides the Big Bang — such as eternal inflation or an oscillating universe.
The phrase "Big Bang Theory" has been popular among astrophysicists for decades, but it hit the mainstream in when a comedy show with the same name premiered on CBS.
The show follows the home and academic life of several researchers including an astrophysicist. The first second, and the birth of light In the first second after the universe began, the surrounding temperature was about 10 billion degrees Fahrenheit 5.
The cosmos contained a vast array of fundamental particles such as neutrons, electrons and protons. These decayed or combined as the universe got cooler. This early soup would have been impossible to look at, because light could not carry inside of it.
Over time, however, the free electrons met up with nuclei and created neutral atoms. This allowed light to shine through aboutyears after the Big Bang. This early light — sometimes called the "afterglow" of the Big Bang — is more properly known as the cosmic microwave background CMB.
It was first predicted by Ralph Alpher and other scientists inbut was found only by accident almost 20 years later. At first, they thought the anomaly was due to pigeons and their dung, but even after cleaning up the mess and killing pigeons that tried to roost inside the antennathe anomaly persisted.
The teams each published papers in the Astrophysical Journal in Determining the age of the universe The cosmic microwave background has been observed on many missions. Planck's observations, first released inmapped the background in unprecedented detail and revealed that the universe was older than previously thought: How Old is the Universe?
The maps give rise to new mysteries, however, such as why the Southern Hemisphere appears slightly redder warmer than the Northern Hemisphere. Examining the CMB also gives astronomers clues as to the composition of the universe. Researchers think most of the cosmos is made up of matter and energy that cannot be "sensed" with conventional instruments, leading to the names dark matter and dark energy.
Only 5 percent of the universe is made up of matter such as planets, stars and galaxies. Gravitational waves controversy While astronomers could see the universe's beginnings, they've also been seeking out proof of its rapid inflation.

The Big Bang Theory is an American sitcom from Chuck Lorre Productions and Warner Bros. Television that airs on CBS in the United States..
The Big Bang Theory is now in its final season on CBS. The twelfth season premiered Monday, September 24, and returned to its regular Thursday night time period on September Origins of the Universe The most popular theory of our universe's origin centers on a cosmic cataclysm unmatched in all of history—the big bang.
This theory was born of the observation that other galaxies are moving away from our own at great speed, in all directions, as if . Video: Big Bang Theory of the Universe: Definition & Overview. Before The Big Bang Theory was a popular television show, it actually referred to the theory that talks about how the universe began.
The Big Bang Theory is an American television sitcom created by Chuck Lorre and Bill Prady, both of whom serve as executive producers on the series, along . The big bang theory is an effort to explain what happened during and after that moment.
According to the standard theory, our universe sprang into existence as "singularity" around billion years ago.
