What happened during the Big Bang?
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 13.7 billion years ago.
What Is the Big Bang Theory?
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 13.7 billion years to the cosmos that we know today.
What is the Big Bang theory in simple terms?
The broadly accepted theory for the origin and evolution of our universe is the Big Bang model, which states that the universe began as an incredibly hot, dense point roughly 13.7 billion years ago.
What is the Big Bang theory definition?
Definition of big bang theory. : a theory in astronomy: the universe originated billions of years ago in an explosion from a single point of nearly infinite energy density — compare steady-state theory.
How did Big Bang start?
The Big Bang Didn't Need God to Start Universe, Researchers Say. This graphic shows a timeline of the universe based on the Big Bang theory and inflation models. SANTA CLARA, Calif. — Our universe could have popped into existence 13.7 billion years ago without any divine help whatsoever, researchers say.
Who first discovered Big Bang Theory?
Georges Lemaître
In 1927, the Belgian Catholic priest Georges Lemaître proposed an expanding model for the universe to explain the observed redshifts of spiral nebulae, and calculated the Hubble law. He based his theory on the work of Einstein and De Sitter and independently derived Friedmann's equations for an expanding universe.
Who is known as the father of the Big Bang theory?

How did Georges Lemaitre discover the big bang?
Georges Lemaître: Discovered the Expansion of the Universe. In 1927, Belgian priest and physicist Georges Lemaître made what is perhaps the greatest discovery in modern cosmology — our universe is expanding. Four years later, he proposed that the universe began with a “single quantum” — what we now call thebig bang
Who discovered Hubble's law?
In 1927, two years before Hubble published his own article, the Belgian priest and astronomer Georges Lemaître was the first to publish research deriving what is now known as Hubble's Law.
What is Hubble law in simple terms?
Hubble's law is the statement in astronomy that galaxies move away from each other, and that the velocity with which they recede is proportional to their distance. It leads to the picture of an expanding universe and, by extrapolating back in time, to the Big Bang theory.
What is Hubble's law formula?
Hubble's Law - One of the most important formulas of the 20th century. It shows the expansion of the Universe by showing how distant galaxies are moving away from us. Formula: v = Ho d where: v = velocity of a galaxy, in km/s. Ho = Hubble Constant, measured in km/s/Mpc.
