- An alternative model which once enjoyed equal status with the big bang is the steady state theory, first proposed in 1948 by Hermann Bondi, Thomas Gold, and Fred Hoyle. This model, too, assumes that the universe is expanding, but proposes that it has no beginning or end in space and time.

- One of the most important figures in modern cosmology is the American astronomer Edwin Hubble. He discovered a universe of galaxies outside the Milky Way and showed that the entire universe is expanding. In the early 20th century, most astronomers believed that the universe did not extend beyond our Milky Way galaxy.

- The Big Bang Theory. Scientists have gathered a lot of evidence and information about the universe, and have used observations to develop the Big Bang Theory. The theory states that originally all the matter in the universe was concentrated into a single incredibly tiny point. This began to enlarge rapidly in a hot explosion (called the Big Bang), and it is still expanding today.

The Big Bang theory The Big Bang theory. The Big Bang theory. The Big Bang theory describes how the Universe began in a rapid expansion about 13.7 billion years ago and has evolved since that time. It is thought that all of space was created in this first moment.

Big Bang Theory: Evolution of Our Universe Currently, the most prevalent scientific theory, known as the Big Bang Theory, is that the universe originated in an enormous explosion. Before the Big Bang, all of the matter and energy now in the universe was contained in a singularity. A singularity is a point with an extremely high temperature and infinite density.

What Came Before the Big Bang? Cosmologist Alexander Vilenkin believes the Big Bang wasn't a one-off event, but merely one of a series of big bangs creating an endless number of bubble universes. Cosmologist Alexander Vilenkin has convincing evidence that we are surrounded by expanding, bubble-like universes.

Name the scientist United States astronomer who discovered that (as the universe expands) the speed with which nebulae recede increases with their distance (1889-1953) This helped establish the theory of the Big Bang.. Many astronomy terms and tools now bear his name.

The Big Bang Theory Watch on. Two nerdy physicists share an apartment and an unlikely friendship with their beautiful neighbor with whom one of them is infatuated. Like the universe after the big bang, the show's popularity expanded, thanks to breakout star Jim Parsons, along with the chemistry among the friends and the developing romance between Leonard and Penny.

- Ernest Rutherford. Ernest Rutherford, 1st Baron Rutherford of Nelson was a New Zealand chemist who has become known as the “father of nuclear physics”. In 1911, he was the first to discover that atoms have a small charged nucleus surrounded by largely empty space, and are circled by tiny electrons, which became known as the Rutherford model (or planetary model) of the atom.

Big Bang theory could be debunked by Large Hadron Collider Big Bang theory could be debunked by Large Hadron Collider. Scientists at Cern could prove the controversial theory of ‘rainbow gravity’ which suggests that the universe stretches back into time infinitely, with no Big Bang. The theory of Rainbow Gravity may prove that the Big Bang could not have happened Photo: Alamy.

Greatest Mysteries: How Did the Universe Begin? Fundamental mysteries. According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.7 billion years ago. Like a rapidly expanding balloon, it swelled from a size smaller than an electron to nearly its current size within a tiny fraction of a second.iew full size image. Editor's Note: We asked several scientists from various fields what they thought were the greatest mysteries today, and then we added a few that were on our minds, too. This article is one of 15 in LiveScience's Greatest Mysteries series running each weekday.

What came before the big bang? In this theory, time moved in a way we would consider backward for billions of years — with the universe contracting all the while — until it shrank to subatomic size. Then the big bang occurred and time began to progress, and the universe expanded, in the way we see now.

Arno Penzias and Robert Wilson At the same time, the two astronomers learned that Princeton University physicist Robert Dicke had predicted that if the Big Bang had occurred, there would be low level radiation found throughout the universe. Dicke was about to design an experiment to test this hypothesis when he was contacted by Penzias.

Early Ideas about Matter: From Democritus to Dalton John Dalton, an exceptional British teacher and scientist, put together the pieces and developed the first modern atomic theory in 1803. To learn more about Priestley's and Lavoisier's experiments and how they formed the basis of Dalton's theories, try the interactive experiment Dalton's Playhouse, linked to below.

Quantum Fluctuations May Kill Big Bang Evangelism Apparently, Tryon was the first to suggest that the universe began in a quantum fluctuation. Perhaps a better example would be the more recent, detailed paper on the supposed quantum fluctuation origin of the universe by Stenger (1989).

Description & Origins of Inflation Theory Developed in 1980 by particle physicist Alan Guth, inflation theory is today generally considered a widely-accepted component of the big bang theory, even though the central ideas of the big bang theory were well established for years prior to the development of inflation theory.

Who was the first person to propose the heliocentric theory? Answer by Joshuaalexanderjohnson. Confidence votes 26. The Heliocentric theory was first proposed about 2300 years ago, by Aristarchus of Samos (310-230 BC). *Some argue that it was the Polish-German astronomer Nicolaus Copernicus (1473-1543), but his hypothesis was dated about 1800 years later.

Big Bang Theory Big Bang Theory-The Premise The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. 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.
