Big Bang Theory (scientific model)

Parent Category: Cosmology
The Big Bang Theory is an event that caused the creation of the universe according to cosmological theories.
Big Bang Cosmology does NOT state that the mass of our Universe  exploded from a single point into empty space. Rather, it states  that the density of Universe has been decreasing at a (more or  less) constant rate over the last 13.77 billion years or so, due to  an EXPANSION of space itself. ...
Mainly hydrogen; also some helium, and small amounts of lithium. Heavier elements (the so-called "metals") were formed later, in stars, through fusion. It is thought that initially there were no chemical elements as we know them. The lighter elements mentioned above came into being after the big...
The Big Bang Theory is not "just a theory" in the same way the  theory of gravity is "not just a theory"    The definition of a scientific theory is what confuses many  ignorant people. In science, a theory is a body of information that  explains natural phenomena, and is very well supported...
The Big Bang theory explains the structure of the cosmos on the largest scale. The nebular hypothesis explains the formation and structure of individual stars and solar systems.
There are no other theories in the scientific sense that explain the beginning of the universe. All other explanations are unsupported hypotheses.
The Big Bang Theory represents the creation event for our existence in a traditional fourth dimensional SpaceTime continuum. Without this environment, there would be no galaxies, solar systems, or planets. So while the Big Bang Theory provided for existence within the universe, the actual formation ...
Well, one reason is because for a long time blacks were often kept out of any job that dealt more with academics. A lot of people believed blacks were not well educated and could not be educated which was/is far from the truth. Blacks moved more toward athletics because, although there were still...
As far as we know, it happened only once.
well one thing that we can observe from the big bang is its cosmic  background radiation
13.7 billions years ago, all matter was infinitely hot and infinitely dense. Space (not matter, but the space containing matter) began to expand very fast, resulting in matter cooling down. The universe consisted of quark-gluon plasma and other elementary particles. Temperatures were so high that...
We can never see the Big Bang or what happened around that time, because photons were not free to travel through the universe yet. It is also important to realize that the word "universe" implies a totality of existence; it is everything that has, does, and ever will exist. So you can't say there is...
it refers to the formation of the universe (stars, and planets).
First, let's set some expectations. The Big Bang Theory is a theory of how the Universe came to be what it is today, given the observational fact that, except for some local gravitational binding, all of the galaxies in the Universe are traveling away from each other at a speed proportional to the...
It is called a theory because that is precisely what it is. It is not called a theory because it 'isn't real'. Evidence is still coming in, and over the next few generations there will be a more solid sense that it is either NOT a good working model of the universe we observe, or it IS a good...
I'm going to presume you left out the word, "support," that you meant to write, "that does not support the Big Bang."The answer is that are none at this date. Until 1990, the only serious observational problem was the existence of white dwarfs that seemed to be older than 13 billion years. These...
Implying that you believe in The Big Bang Theory then yes our "World" aka Earth was created from the products of The Big Bang.
  the big bang theory is accepted by science because there is an incredible amount of evidence leading scientists to believe it is true. For example, it was theorized that if the big bang were true, we should see microwave radiation in a very particular way in space. And when we looked the...
The Big Bang is the dominant (and highly supported) cosmology of the beginning state of our Universe. In essence, it states that our Universe began from an initial state of very high density and temperature, which has expanded over billions of years to form a Universe as we now observe it. Together...
We can never see the Big Bang or any time around then because photons were not free to travel through the universe yet. It is possible that before the Big Bang there was no temperature to measure.
No.   Answer Yes I disagree, with the first answer. The Bible says God created the Heavens and the Earth and God is Everlasting. It is more proof that He does. He spoke it into existence.
The chemical elements (excepting H, He, Li, Be) are formed by stellar nucleosynthesis.
Before the CMBR was ever observed, it followed from the Big Bang theory that the CMBR should have a particular temperature, and that the variations in the background should have a particular distribution and range of sizes. The CMBR, when it was detected, matched those predictions very closely.
CERN is a place where particles are collided; they actually do many  different experiments.
The Big Bang Theory present the theoretical premise for the causation, termination, and continuation of an evolutionary expansion of the universe. The Big Bang promotes that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space...
Not according to the "Standard Model" the jury is still out on that question!
During the Big Bang, there was an infinite amount of energy present, with infinite temperature. It was so hot, the four forces, Gravity, Electromagnetism, Strong nuclear and weak nuclear all were unified. As the universe cooled, Gravity, an attractive force present with all matter with mass, broke...
There is no objective reference to a poll taken to decide what the public thinks about the Big Bang Theory. Perhaps this is meant to address some information that was presented in a classroom setting.
I presume the question refers to the "redshift" of distant galaxies. Actually it is the other way around - i.e. the Doppler redshift helps to support and explain the Big Bang Theory. This "redshift" is called the "cosmological redshift". Strictly speaking, it's not the Doppler effect.
Uranium and the majority of the other elements (excepting H, He, Be, Li, transuranium elements) are formed after the big-bang (creation of the universe) by stellar nucleosynthesis in novas and supernovas. .
Georges Lemaître(1894-1966) is considered the Father of the Big Bang.
13.7 billions years ago, all matter was almost infinitely hot and infinitely dense. Then space (not the matter in space, but space itself) began to expand very fast, resulting in matter cooling down. The universe consisted of quark-gluon plasma and other elementary particles. Temperatures were so...
The birth of the universe has been debated throughout the years and only one theory continues to persist, the the Big Bang. Using theories and observations from many scientists. the Big Bang provides a simplistic and logical explanation reguarding the orgin of the universe
How about with a summary of predicted conjectures from the Big Bang Theory - like the possible end of our observable universe.
As you probably covered the beginning and stages with the expansion phase, with a proper rationalization of observable evidence, I would guess you could end your paper with a discussion of what the Big Bang model suggests for the probable futures of the universe (and eventual termination).

Physics . Physics is the study of matter, energy and the interactions of the two. Physics can be divided into two main branches: mechanics (the study of the behavior of forces and objects acting due to those forces); and, electricity and magnetism (which delves into the science of the atom). ...

The big bang happened something like 14 billion years ago. As an instant in time that is true, as a process it is still happening at every point in space as that point expands into a finite volume and drags matter and energy with it.
Because that is what our standard model of the universe tells us. It is due to the red shift of light showing that our universe is expanding away from a point. Now since we know time moves in a linear fashion, it is not hard to imagine that if we reverse this expansion, the whole universe is brought...
Hydrogen and helium.The ratios of hydrogen to helium to deuterium in our Universe are almost perfectly as predicted by the Big Bang. Every other hypothesis has to say, "I don't why those are the ratios in our Universe -- they just are."
Edwin Hubble, the man that invented the Hubble telescope, discovered evidence to support the big bang theory. In 1929, Edwin Hubble discovered that the distances to far away galaxies were generally proportional to their redshifts-an idea originally suggested by Lemaître in 1927. Hubble's...
The Big Bang is the cosmological model of the initial conditions and subsequent development of the Universe that is supported by the most comprehensive and accurate explanations from current scientific evidence and observation. As used by cosmologists, the term "Big Bang" generally refers to the...
All matter was conglomerated into a singularity - a point with basically no volume but extremely high mass and "infinite" density. Something (which is currently indeterminate by science) made this unstable and the universe began expanding rapidly.The resulting energies moved the matter apart and...
As used by cosmologists, the term Big Bang generally refers to the idea that the Universe has expanded from a primordial hot and dense initial condition at some finite time in the past (best available measurements in 2009 suggest that the initial conditions occurred around 13.3 to 13.9 billion years...
Jesuit priest George LeMaitre first developed this model for what our Universe is doing at this time. Albert Einstein initially ridiculed the idea, but later acknowledged that the priest had corrected (as Einstein himself called it) his "greatest blunder."
the main weakness is that no one knows how the explosion started as it created everything so there couldn't have been anything to start it because it would have to exist before it existed which is paradoxical.The big bang supposibly occured 15 billion years ago but cluster galaxies have been found...
In 1927, Georges LeMaitre was the first to propose, based on Edwin Hubble's findings, that the universe was expanding from an extraordinarily hot and dense initial state. Fred Hoyle coined, much later, the term Big Bang to describe this expansion. Later observations, including the key observation of...
in my view there is no big bang theory vs religion, since the theory it self gives credibility to the genesis story based on GOD creating the universe and all life forms.
The Steady State Hypothesis WAS the only SCIENTIFIC alternative to Big Bang Cosmology. It is now been rejected by all but a fringe of scientists. No other hypothesis makes any serious claim to scientific support.
Scientists "speculate" that the Big Bang created antimatter, but it was destroyed when coming into contact with stars, planets, and other matter.
13.5 billion years ago.
  There are a number of reasons to suspect that the universe started from a point:   1) All the distant galaxies are headed away from us, so 13.7 billion years ago they were in one spot..   2) The macro-universe is no different on opposite sides. Nothing has had the time to smooth out both...
Boobs. There was one massive pair of jugs that became the universe. Yes. You sir, are a tit.
A theory suggests that the universe may be like a pulse that keeps on expanding and contracting. When the universe has no where else to expand to after the big bang, and the force of gravity brings it back into its original position, the point of singularity may happen again, from all the compressed...
The theory was first discussed about 80 years ago.The Big Bang itself is estimated to have happened about 13.7 billion years ago.
The existence of galactic clusters is consistent with the Big Bang although it would be equally consistent with the alternative Steady State theory.
the effects of the Bing Bang Theory are what we see around today.The bing bang theory led to the formation of the stars,the planets ,the galaxies etc.as it expanded.As the universe expanded it became cooler and cooler and thus the earth and other planets were able to form a hard outer ,solid layer...

Islamic answer: Per Islam teachings and per the God holy book of Quran, Allah (or God and same God worshiped in Christianity and Judaism) is the first before any first we know or we don't know and the last after any last we know or we don't know. َQuran says (meaning English translation) (57...
The current estimate for the initial expansion of the universe dubbed "The big bang" occurred about 13.7 billion years ago.    See related link for more information.
The Big Bang Theory can so far only describe what our Universe was like after it began to expand -- it can NOT (so far) tell us what happened right at the start of that expansion, or what happened "before" (if that term has meaning).Prior to about 10^-40 seconds after the start of expansion, our...
Scientists have speculated that the separation of the strong force from the electro-nuclear force caused it. But you have to think of it this way... time might have not existed before the big bang so could anything cause it... ?
It was so hot that it can burn the sun. it was infinity degrees  Celsius 10 billion billion
The Big bang theory states that the galaxies are in fact moving away from each other
The first article proposing the idea now known as Big Bang Cosmology was written by Jesuit priest Georges LeMaitre. Alexander Friedmann had noted, in 1925, that an expanding Universe was a mathematical solution to general relativity, but never stated that (1) our Universe actually WAS expanding or ...
Probably like the Jesuit priest, George LeMaitre, who first proposed the idea of the Big Bang-- he'd think it was a pretty good scientific effortl.
Actually it is the other way around - i.e. the Doppler shift helps to support and explain the Big Bang Theory. Edwin Hubble is credited with the discovery that the distances to far away galaxies are generally proportional to their redshifts (as in the Doppler effect); an idea which was originally...
-- They're only theories. -- They're the best, most successful explanations offered so far for everything that's observed in space, and everything that's observed in the ground on earth, respectively.
Hubble's red shift observation.
Georges Lemaître proposed what later became known as the Big Bang theory in 1946. He called it L'Hypothèse de l'atome primitif" (Hypothesis of the primeval atom).
Define "big bang earthquake"; it's not a term we're familiar with.Edit: I agree. Some people have strange ideas about the Big Bang. Let's give them a break. Let's guess they just want to know when it happened. The present answer, from scientists, is about 13.7 billion years in the past.
Prior to our universal reality within a fourth dimensional existence, the instance of universe is modeled within the creation event called the Big Bang. The pre-Big Bang is a theory, in which all the essence of our universe was previously defined within a singularity, is really an extreme condition...
hi yours is a new question but anyway it's in doubt since very longwhereas the matter available in universe is somewhat alike that is the only which shows that the total cosmos's origin is from single unit.........universe was like burning stars nebulas and other gig bodieswhich were just gases only...
We have no idea what, if anything, existed before the Big Bang, or even if the concept of "before" has any meaning in this context.
Scientists do not 'believe in' theories. They gather evidence for them and build them up with experiment and observation or reject them if there be contradictory evidence. The Big Bang Theory is accepted due to the presence of much evidence, such as: Arno Penzias and Robert Wilson's telescope's...
Father Georges Lemaitre.
A sound is compression waves moving through matter, like air, water or even the ground. A noise is generally regarded as random sound vibrations. Since there was more matter in one place (the entire universe) than there ever has been since and more random vibrations than ever since, we could say the...
Model of the origin of the universe, which holds that it emerged from a state of extremely high temperature and density in an explosive expansion 10 billion-15 billion years ago. Its two basic assumptions-that Albert Einstein's general theory of relativity correctly describes the gravitational...
The answer is simple: we're not sure. As Alan Guth stated so well:  "The Big Bang theory says nothing about what banged, why it banged,  or what happened before it banged."
No, hydrogen was. other heavier elements, starting with helium, were formed by the nuclear fusion of hydrogen nuclei.
In 1925, Alexander Friedmann took the mathematics of general relativity, and showed that our Universe could either be expanding or contracting.In 1927, Jesuit priest Georges LeMaitre proposed the idea that our Universe was expanding, and that we should thus see red-shifts in distant galaxies.Very...
Georges Lemaitre, a Catholic priest and scientist, was the first to suggest the basic idea.
Jesuit priest Georges LeMaitre developed Big Bang Cosmology (BBC) when he noted that the equations for general relativity allowed for an expanding universe or a contracting universe, but not for the infinitely steady universe that Einstein believed in. He also suggested that the red shift seen for...
Dr.Lyn Evans discovered it.
The big bang theory was supposedly created by 1/1,000,000th of an electron and that is impossible. A conversation that was between Ravi Zacharias and Vick ramsine, who in the minds of some are highly respected world experts in bioevolution and astrophysics: "The possibility of the human enzyme...
well look at the solar system everything is in order ask yourself this if i had a bag full of stones and put a dynamite in the center and blow it up will everything be in order that is proof.Scientists have prooven that the earth was once a planet of water so people back in 2000 years ago would,NT...
Proof of theories is an idea that trips up many people who are looking to make sense of sometimes widely differing views. No fundamental theory can ever be proven. There is no special Pronouncement that comes down to verify that a theory has become a "Law". It was thought that Newton's equations...
It is the current working theory of the origin of the universe. It is the paradigm that Astronomy is based upon. But, new evidence is always being described. The theory itself might change as our knowledge grows.
Possibly an unending cycle of Big Bangs and Big Crunches. Or, it's also possible that there was nothing at all. Nonexistence.
All matter formed together in a tiny ball smaller than an atom. All the force was too much, so the ball exploded. Tiny particles of matter gathered together to form planets.
