The main disadvantage of the Big Bang theory probably lies in our inability to explain where the original "ball" of energy came from that did the expanding (the "Bang") to form the universe and the spacetime that it occupies. Note, if you please, that the universe did not expand into an "empty" universe or volume of space, but involved all the energy that "condensed" and the creation of spacetime in which to exist.

Big Bang Cosmology (BBC) states the space within our Universe has been expanding at a (more or less) constant rate, for a period of time on the order of ten billion years.… BBC does NOT state there was an explosion of matter into empty space, it states that space itself has been expanding. Hope this helps. : )
big bang theory was stated by Edwin Hubble (1889-1953).It states that the universe originated from a huge collision between two particles of concentrated mass.The after effect… of that collision has resulted in the formation of the universe.The stars and the galaxies were formed from the explosion .It also states that the universe is also expanding and ths is getting colder and colder. Almost every statement in the previous paragraph is just plain wrong. Edwin Hubble did not develop the theoretical structure of the Big Bang, that was done by Jesuit Georges LeMaitre. Hubble confirmed that the distance between us and all other galaxies is expanding, and that the rate of this expansion depends on the distance to that galaxy. Thus, Hubble only confirmed one prediction of BB Cosmology, but had nothing to do with its theoretical development. We have no idea what happened BEFORE the start of expansion, but it is almost certainly was NOT "a huge collision between two particles of concentrated mass." What happened afterwards was NOT an explosion of concentrated matter into empty space, but an expansion of space itself.
Fred Hoyle coined the term Big Bang. He dismissed the idea of an explosion-like beginning to the Universe as 'cartoon physics' and thus the term Big Bang was derogatory. Howev…er the theory is now accepted by most scientists. The term Big Bang has stuck and is no longer derogatory. It may be one of the most entertaining terms of Cosmology.
BIG Bang is a hypothesis and on the basis of cern research big bang theory was proposed.
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 decr…easing at a (more or less) constant rate over the last 13.77 billion years or so, due to an EXPANSION of space itself. Think of space as like an balloon, and matter as like ink on the balloon. Big Bang Cosmology states that the BALLOON has been growing larger, NOT that ink splattered on the balloon.
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 the random motions of particles were at relativistic speeds, and particle-antiparticle pairs of all kinds were being continuously created and destroyed in collisions. Baryogenesis (production of an asymmetry between baryons and anti-baryons) leaded to a very small excess of quark and leptons over anti-quarks and anti-leptons. (That's why we have more matter than antimatter in the universe) The Universe continued to grow in size and fall in temperature. Quarks and gluons combined to form baryons such as protons and neutrons. The temperature was now no longer high enough to create new proton-anti-proton pairs. There was a mass annihilation (destruction) that leaved 1/10 000 000 000 of the protons and neutrons, and none of their antiparticle. A similar process happened for electrons and positrons. A few minutes later, neutrons combined with protons to form deuterium (heavy hydrogen) and helium nuclei. After about 379 000 years the electrons and nuclei combined into atoms. Over a long period of time, the slightly denser regions of the nearly uniformly distributed matter gravitationally attracted nearby matter and grew even denser, forming gas clouds, stars, galaxies, etc. The answer is : The entire universe was formed in a massive explosion that threw all the material that makes up the universe out in all directions at a great speed. *** The previous sentence is completely wrong. There was no explosion of matter from a central point into empty space, it was an EXPANSION, not of matter, but of SPACE ITSELF.
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 ve…ry high density and temperature, which has expanded over billions of years to form a Universe as we now observe it. Together with Inflation, certain predictions of what we would see today in our Universe are made -- and pretty much all of said predictions have been confirmed.
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 obse…rvation was taken to indicate that all very distant galaxies and clusters have an apparent velocity directly away from our vantage point: the farther away, the higher the apparent velocity. Other comment: Almost literally everything about cosmology screams "big bang". The fact that nearly everything in the universe is moving away from us, the fact that this is strongly correlated with distance (things further away are moving away faster), the cosmic microwave background... all of it says that about 13 billion years ago the universe was very dense and very hot.
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 a…go. Its two basic assumptions-that Albert Einstein's general theory of relativity correctly describes the gravitational interaction of all matter and that an observer's view of the universe does not depend on direction of observation or on location-make it possible to calculate physical conditions in the universe back to a very early time called the Planck time (after Max Planck). According to the model proposed by George Gamow in the 1940s, the universe expanded rapidly from a highly compressed early state, with a steady decrease in density and temperature. Within seconds, matter predominated over antimatter and certain nuclei formed. It took another million years before atoms could form and electromagnetic radiation could travel through space unimpeded. The abundances of hydrogen, helium, and lithium and the discovery of cosmic background radiation support the model, which also explains the redshifts of the light from distant galaxies as resulting from the expansion of space.
Most likely not, but I really hope so.
if your in America it's on CBS if your in Australia in on channel nine go or comedy channel
Kripke is one of Sheldon's worst enemies. He has a lisp sort of thing that he pronounces "r"'s with "w"'s so it would be Kwipke.
Yes, that's why it's called a theory. It's important to realize, however, that science uses the term "theory" in a different way than the general public. The popular meaning… of "theory" is akin to "wild guess", while in science a theory is a posited explanation that is testable, backed by evidence, and predictive. It's also important to realize that "big bang theory" does not purport to explain, in Alan Guth's words, "what banged, what happened before it banged, or what caused it to bang". It is best considered as a theory that, given the observational evidence that a bang apparently occurred, how do we get from the initial conditions implied by that bang to the current state of the Universe today?
Big Bang Cosmology was first proposed (although not by that name) in 1930 by Jesuit priest Georges LeMaitre. It became the standard cosmology after the discovery of Cosmic Mic…rowave Background Radiation in 1964, and all alternatives to BBC are now almost pseudo-science.
