Big Bang
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. It was first proposed as a physical theory in 1931 by Roman Catholic priest and physicist Georges Lemaître when he suggested the universe emerged from a "primeval atom". Various cosmological models of the Big Bang explain the evolution of the observable universe ...
The Big Bang
Overview. The origin, evolution, and nature of the universe have fascinated and confounded humankind for centuries. New ideas and major discoveries made during the 20th century transformed cosmology - the term for the way we conceptualize and study the universe - although much remains unknown. Learn more.
Big-bang model
The big-bang model is based on two assumptions. The first is that Albert Einstein 's general theory of relativity correctly describes the gravitational interaction of all matter. The second assumption, called the cosmological principle, states that an observer's view of the universe depends neither on the direction in which he looks nor on ...
What is the Big Bang Theory?
The name "Big Bang Theory" has been a popular way to talk about the concept among astrophysicists for decades, but it hit the mainstream in 2007 when a comedy T.V. show with the same name ...
What Triggered the Big Bang? It's Complicated
The Big Bang theory is a scientific model, just like any other scientific model. We believe the theory is on the right track because it's — gasp — supported by extensive evidence. You don't ...
The science behind the Big Bang theory
Credit: BNL. The first suggestion of the Big Bang was in 1912. Astronomer Vesto Slipher "conducted a series of observations of spiral galaxies (which were believed to be nebulae) and measured ...
The origins of the universe facts and information
The most popular theory of our universe's origin centers on a cosmic cataclysm unmatched in all of history—the big bang. Learn about the big bang theory and how our universe got started. Skip to ...
How did the Big Bang get its name? Here's the real story
The first cosmological theory of the Big Bang type dates back to 1931, when Belgian physicist and Catholic priest Georges Lemaître proposed a model based on the radioactive explosion of what he ...
What is the Big Bang Theory? How did our universe begin?
The Big Bang Theory is a scientific definition of the origin of the universe that is widely accepted. ... Based on observations, scientists have determined that the universe is expanding in all directions, suggesting that it is likely infinite in size. ... influencing various fields of scientific research, such as cosmology, astrophysics, and ...
The early universe
Hubble's discovery was the first observational support for Georges Lemaître's Big Bang theory of the universe, proposed in 1927. Lemaître proposed that the universe expanded explosively from an extremely dense and hot state, and continues to expand today. Subsequent calculations have dated this Big Bang to approximately 13.7 billion years ...
What Came Before the Big Bang?
By definition, the Big Bang is the time when the scale factor was zero—everything was squeezed into a dimensionless point. During inflation, the scale factor increased with exponential speed.
What happened in the early universe?
The Big Bang theory of cosmology successfully describes the 13.7 billion years of evolutionary history of our Universe. However, it is known that the current Big Bang theory cannot self-consistently explain its initial conditions. We are interested in finding out what caused the Big Bang, and the physics involved in this primordial epoch.
The Universe Began with a Bang, Not a Bounce, New Studies Find
In particular, the big bang model of the universe begins with a singularity—a point that appeared out of nothing and contained the precursors of everything in the universe in a region so small ...
The Big Bang Theory: How the Universe Began
The Big Bang theory represents cosmologists' best attempts to reconstruct the 14 billion year story of the universe based on the sliver of existence visible today. Different people use the term ...
What is the Big Bang Theory?
The basics of the theory are fairly simple. In short, the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time, roughly 13.8 ...
Evidence for the Big Bang
The Big Bang theory predicts how much of each element was made in the early universe. When astronomers look at very old galaxies and stars, the amount of each chemical they see agrees with the Big Bang theory. You cannot look for this evidence in new stars, like the Sun. This is because newer stars contain chemical elements made by older stars.
Did the Big Bang really happen? Scientist disputes universe's origin story
The Big Bang is so widely accepted as the origin story of the universe that most people forget it is still a theory, and not proven fact. But new research led by astronomer Eric Lerner disputes ...
Big Bang Theory: Assumptions & Scientific Evidence Essay
The Big Bang Theory is one of the theories that explain the origin, development, and the nature of the universe. The theory uses physical laws and cosmic forces in elucidating the origin, development, and the nature of the universe. The premise of the Big Bang Theory is that the universe originated from a massive explosion of a mass of atoms.
What Astronomers Are Still Discovering About the Big Bang Theory
The scientists had found evidence that would confirm the Big Bang theory, first proposed by Georges Lemaître in 1931. "Until then, some cosmologists believed that the universe was in a steady ...
How Did The Bang Theory Come About?
In fact, the term 'Big Bang' was coined by a prominent physicist in 1949 to mock the idea. In the middle of the 20th century, researchers in the field of cosmology had two warring theories. The one we would come to call the Big Bang suggested the universe expanded rapidly from a primordial, hot, and ultra-dense cosmos.
History of the Big Bang theory
The history of the Big Bang theory began with the Big Bang's development from observations and theoretical considerations. Much of the theoretical work in cosmology now involves extensions and refinements to the basic Big Bang model. The theory itself was originally formalised by Father Georges Lemaître in 1927. Hubble's Law of the expansion of the universe provided foundational support for ...
(PDF) About the theory of the Big Bang
The weaknesses of this theory are shown. We proposed a new hypothesis of the Big Bang, in which the center of the explosion is absent. Because of the interaction of the atoms of the baryonic ...
This Is The Real Scientist Behind The Big Bang Theory
The Bazinga-yelling main character of the show, Sheldon Cooper (Parsons), has a photographic memory and a job as a theoretical physicist, where he spends most of his time researching such heavy ...

Can the Big Bang Theory and Biblical Creation Be Reconciled?
The Big Bang Theory and Faith. For Christians, the Big Bang Theory raises questions about the compatibility of faith and science. It is important to approach this issue with humility and a willingness to engage in thoughtful dialogue. While the Big Bang Theory offers one possible explanation for the origin of the universe, it is not the only ...
