5 things you always wanted to know about the Big Bang theory and the
Questions about the Big Bang theory and answers that reveal the thinking behind the biggest question of all: where everything came from.
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.
Big-bang model
big-bang model, widely held theory of the evolution of the universe. Its essential feature is the emergence of the universe from a state of extremely high temperature and density —the so-called big bang that occurred 13.8 billion years ago. Although this type of universe was proposed by Russian mathematician Aleksandr Friedmann and Belgian ...

PDF Evidence for the Big Bang
The Big Bang theory is an explanation of the early development of the Universe. According to this theory the Universe expanded from an extremely small, extremely hot, and extremely dense state. Since then it has expanded and become less dense and cooler. The Big Bang is the best model used by astronomers to explain
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.
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 ...
WATCH: Questions About the Big Bang (video)
The big bang theory is at this stage for those who have studied physics. There are still many unanswered questions, some of which are mentioned in this video, but that's what keeps things interesting! Science depends on physical measurements, and it answers questions about the physical world. Because of this, our understanding of the big bang ...
What Is the Big Bang?
In 1927, an astronomer named Georges Lemaître had a big idea. He said that a very long time ago, the universe started as just a single point. He said the universe stretched and expanded to get as big as it is now, and that it could keep on stretching. What an Idea! The universe is a very big place, and it's been around for a very long time.
Understanding the Big-Bang Theory
The theory behind the origin of the universe. The big-bang theory is the dominant theory of the origin of the universe. In essence, this theory states that the universe began from an initial point or singularity, which has expanded over billions of years to form the universe as we now know it.
The Big Questions
In physics, the Big Bang Theory describes not the beginning of the universe (much less a "bang") but rather the evolution of the universe. During the first half of the 20th century, Edwin Hubble and other scientists demonstrated that the universe is expanding. In its basic essence, the Big Bang Theory is the theory of the expanding universe.

Stephen Hawking's final theory challenges the existence of the multiverse and argues the Big Bang had a finite boundary, defined by string theory and holograms. Full Episode Sunday, May 12
The matter-antimatter asymmetry problem
The Big Bang should have created equal amounts of matter and antimatter in the early universe. But today, everything we see from the smallest life forms on Earth to the largest stellar objects is made almost entirely of matter. Comparatively, there is not much antimatter to be found. Something must have happened to tip the balance.
Evidence for the Big Bang
It is very good evidence that the Big Bang theory is correct. The Sun is a fairly new star. Credit: NASA. 3. Mixture of Elements. Some chemical elements were created soon after the Big Bang. Elements like hydrogen and helium. The Big Bang theory predicts how much of each element was made in the early universe.
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 ...
No, the Big Bang theory is not 'broken.' Here's how we know
The potential problem with distant galaxies isn't that they exist. In fact, the modern formulation of the Big Bang theory, called ΛCDM cosmology (the Λ stands for dark energy, and CDM is short ...

As a mere viewer of The Big Bang Theory, I can't answer this question with certainty, but as a physicist, I can offer a couple observations: The equations that appear on the whiteboards in TBBT are from widely varied fields of physics and chemistry. They cover a much wider scope than a typical scientist would actually be working on. Of course ...
Big Bang Theory Called Into Question by Cosmologists
space-exploration. A lot can happen in a universe in 13.8 billion years, and scientists have indeed kept busy studying the wide breadth of events that shaped our cosmos. But one event that had seemed widely accepted — the Big Bang theory — has come under close scrutiny by some cosmologists. They call into question not just when the universe ...
A key part of the big bang remains troublingly elusive
The CMB indicates that when the universe was just 380,000 years old, it had nearly the same density of matter everywhere. And today, astronomers see galaxies in every direction. But the CMB is ...
