what is the big bang physics?

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 13.8 billion years to the cosmos that we know today.

The Big Bang is the singular cataclysmic event that started it all: the instant 13.8 billion years ago that marked the fiery birth of the universe.

The earliest phases of the Big Bang are subject to much speculation, since astronomical data about them are not available. In the most common models the universe was filled homogeneously and isotropically with a very high energy density and huge temperatures and pressures, and was very rapidly expanding and cooling.

The Big Bang Theory is popular because it allows people to pretend to be smarter than they are for half an hour. The show is, at its core, no different to any other popular, middle-of-the-road sitcom. It's essentially Friends for its time.

A new particle with a mass of 125 GeV was discovered in 2012 and later confirmed to be the Higgs boson with more precise measurements. The Higgs boson is an elementary particle in the Standard Model of particle physics, produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory.

Quantum physics (also known as quantum mechanics, or QM) is more general. ... Particle physics, on the other hand, involves the application of QM or other fundamental type of theories to specific particles that we see in nature. You probably know about atoms.

Matter is the stuff in the universe. To be more exact, matter is material that occupies space and has mass. Mass is how we measure the amount of matter, and scientists like to use kilograms. ... Two objects can have the same mass and different volumes, or different masses and the same volume.

Physics is the study of Forces and the effects on it's interactions with matter and energy while applied physics is the study of the usefulness of physics laws and theories with respect to industrial applications for large scale commercialization.

The Big Bang theory is a cosmological model of the observable universe from the earliest known periods through its subsequent large-scale evolution. ... Detailed measurements of the expansion rate of the universe place the Big Bang at around 13.8 billion years ago, which is thus considered the age of the universe.

The idea of a moving and expanding universe, a notion that underlies the Big Bang theory, was strongly influenced by Hubble's Law, according to which there is a relationship between a galaxy's distance from Earth and the speed with which it is moving away: the farther, the faster.

Biology is the study of living organisms. Physics is the study of matter and the laws of nature to understand the behavior of matter and the universe. The Biophysical Society explains that, when scientists combine physics and biology, they learn more about biological systems on a molecular or atomic level.

Elegant books, TV shows, and grandiose TED talks have hyped it to the public. Brilliant theoretical physicists tell us that this theory is the best answer to the hardest problem that their field has ever attacked. All that is fine, but here's the unequivocal truth: string theory has failed as a scientific theory.

Fred Hoyle famously coined the term “big bang” in 1949, but it took a long time to catch on. Helge Kragh shows how the story of the name is also the story of how modern cosmology emerged.

The Big Bang Theory is an explanation that shows the origin of the stars, planets, galaxies and the Universe as a whole. Scientists believe that the Big bang was the very beginning of the creation of this Universe. Scientists state that the Big Bang occurred about 13.73 billion years ago.
