Big Bang Theory (scientific model)

"Emence" may be a misspelling of "immense," which means extremely large or vast. It is often used to describe something of great size or importance.

The child catcher in "Chitty Chitty Bang Bang" was played by actor Robert Helpmann. Helpmann was a renowned Australian actor, dancer, and choreographer known for his work in both theater and film.

The Big Bang theory is a scientific explanation for the origin of the universe, focused on the expansion from a very high-density state. This scientific theory does not necessarily imply the non-existence of a higher power or God. Many people see the Big Bang as a part of a larger divine plan or view the scientific understanding of the universe as compatible with their religious beliefs.

The facts that provide evidence that the space within our Universe was almost infinitely dense about 13.7 billion years ago, and has been expanding at a (pretty much) steady rate ever since, are overwhelmingly persuasive.

1) The distance between us and all distant galaxies is increasing, and the rate at which that distance is increasing is directly proportional to the distance to those distant galaxies.

2) The existence, spectrum, and isotropy of the cosmic microwave background radiation.

3) The ratio of hydrogen to helium in all parts of our Universe.

4) Quasars are seen far from us, but not close to us.

5) The ratio of long-lived isotopes to their decay products.

6) The absence of white dwarf stars older than about ten billion years.

These facts make Big Bang Cosmology as solid an idea as a heliocentric solar system.

Perhaps the most important contribution of radio astronomy to the Big Bang theory was to finally put to rest its only real rival, the Steady State theory.

Steady State theory required the Universe to be eternally similar to the way it is today, with the known expansion of the Universe compensated for by a continual creation of matter in intergalactic space.

However, in 1965, Arno Penzias and Robert Wilson, working with a Bell Labs horn antenna at Holmdel, New Jersey, (and looking for quite something else entirely) discovered a uniform microwave hiss coming from all over the sky. This turned out to match a prediction by George Gamow and others that the Big Bang should leave just such a remnant noise filling the Universe.

The Steady State theory had no explanation for the existence of this noise (now termed the cosmic microwave background), while the Big Bang theory not only demanded it but rather closely predicted its temperature.

The term that best describes the conditions immediately following the big bang is "hot and dense." During this time, the universe was filled with extremely high temperatures and energy, with all matter and energy compressed into a very small, dense space.

The Big Bang theory is a scientific explanation for the origins of the universe, proposing that it began as a singularity and has been expanding ever since. Other theories, such as steady-state or oscillating universe models, propose alternative ideas for the origin and evolution of the universe that differ from the Big Bang theory. The key difference lies in how these theories explain the creation and development of the cosmos.

After the first few hundred million years after the Big Bang, the universe was still in a hot, dense state, with elementary particles forming and ions beginning to combine into atoms. Gas clouds started to condense, leading to the formation of the first stars and galaxies. This marked the beginning of the universe's transition from a primarily uniform state to one with structures and complexity.

A pure chemist could test a novel molecular theory by conducting experiments in a controlled laboratory setting. This could involve synthesizing molecules predicted by the theory and studying their properties using techniques such as spectroscopy, chromatography, and crystallography. By comparing experimental results with theoretical predictions, the validity and accuracy of the novel molecular theory can be assessed.

The CoBE (Cosmic Background Explorer) proved, beyond any doubt, that the spectrum of the CMBR is that of a black-body of temperature 2.7K -- some researchers were finding slight differences from this. The VERY minor anisotropies (about one part in 10,000) found in the CMBR are consistent with matter clumping in the early Universe, just enough to produce galaxies.

Note that WMAP and the Planck Probe have done even more precise measurements, and continued to get results consistent with CoBE.

The three stages of the Big Bang are the primordial nucleosynthesis, the recombination era, and the cosmic microwave background radiation era. In primordial nucleosynthesis, the first nuclei formed; during the recombination era, hydrogen atoms formed; and in the cosmic microwave background radiation era, the Universe cooled down enough for light to travel freely.

No - That is a premise of the Steady State Theory. Rather the universe has been undergoing an evolutionary expansion in which the actual environmental state of the universe is ever changing. The interpretation of observational evidence from the detection of deep space radiations have provided us a window into the past; wherein the universe of the CMBR barrier demonstrates that the universe was once just a soup of hot dense plasma.

(See related question below for more information.)

First, let's define terms.

The "horizon problem" is the fact that the observable Universe is too uniform. If one does calculations based on simple Big Bang Cosmology -- ie, that the present rate of expansion ("Hubble Expansion") is the rate that has existed since the start of time -- then our Universe did not have enough time to reach the mass density uniformity we see today. It's as if we, while planning to make some iced tea, placed a pan of boiling water a meter away from a pitcher of ice, turned away for one second, and then found the water in both containers was now at room temperature. You'd have every right to ask, "How did they reach equilibrium that quickly?"

The "flatness problem" is the fact that the mass density of our Universe is SO CLOSE to the amount that permits stars to form. A Universe more dense than ours would have collapsed in on itself in less than a billion years, and a Universe less dense would have resulted in matter so thin that galaxies would have never formed. In both cases, no heavy elements would have formed in rings around stars, meaning no life could exist. The ratio of the actual mass density and the density that would permit life in our Universe is called Ω. Again, if one does calculations based on simple Big Bang Cosmology, Ω can differ from one by less than 10^-16 (yes, that's a decimal point followed by FIFTEEN ZEROES!), or no life should exist in our Universe.

Inflation simply states that, prior to the Hubble Expansion we now see, our Universe was sufficiently dense for a long enough time that it could reach mass equilibrium, which was then followed by a rapid expansion ("Inflation"), which was then followed by Hubble Expansion.

If one does the calculations based on an inflationary model, one finds that Ω can differ from one by almost any amount, but will eventually reach near unity when inflation ceases. From then on, Hubble Expansion can continue with Ω being the number we see.

Inflation solves other problems as well; but it also makes predictions about what we would see in our present Universe. Specifically, we would see anisotropies in the Cosmic Microwave Background Radiation of a certain size, but no larger. So far, all observations of the CMBR fail to rule out the Inflation Model.

Advantages: Simple to implement and robust against disturbances due to its on-off nature. Disadvantages: Prone to chattering (rapid switching between control actions), which can lead to mechanical wear and increased energy consumption. May not handle non-linear processes well.

It depends, because some might say 'scientists'. But not all scientists believe in this theory.

Also, there are those who believe in a similar idea to the Big Bang, but it is not refered to as 'The Big Band Theory.'

Around half of Americans do. It's not an atheist belief it is evidence-based science accepted by many religious people too.

Gravity played a key role in causing dust and gas to come together after the Big Bang. As matter expanded and cooled, small variations in density led to the aggregation of particles due to gravitational attraction. Over time, this process resulted in the formation of stars, galaxies, and eventually planets.

The creators of the television show "The Big Bang Theory" are Chuck Lorre and Bill Prady. They developed the show together and are also credited as executive producers.

you could give the child examples like

when you pour salt into a glass of water after a few miniatures people think that the salt has dissaperd but no

the salt has dissolved and you cant see it because its INVISIBLE.

No, the Big Bang was the initial explosion that is theorized to have created the universe almost 14 billion years ago. It is not something that can be seen on TV or observed in real time.

The Big Bang is a theory in cosmology that explains the origin and evolution of the universe, supported by a significant amount of observational evidence. It is not a hypothesis, as a hypothesis is an initial explanation to be tested and either supported or rejected based on evidence.

When you hear a loud bang that feels like it is going through your body, it could be due to a sudden and intense acoustic shock. This can happen if you are exposed to a very loud sound or explosive noise, which can cause physical sensations like pressure or vibration in your body. It is important to protect your ears from loud noises to prevent potential damage to your hearing.
