What is the disadvantage of the Big Bang theory?
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.

It deals with the formation of the modern Universe
Jesuit priest Georges LeMaitre was the first to show, scientifically and mathematically, that our Universe could be subject to the laws of General Relativity and be in a const…ant state of expansion. Einstein initially ridiculed LeMaitre's idea, but Edwin Hubbell showed that LeMaitre's ideas were completely correct. Einstein later admitted that his own solution was his "biggest blunder." Einstein and Hubbell are famous throughout the world (and justifiably so) but, for some reason, Jesuit priest LeMaitre has been forgotten.
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.
Fred Hoyle was a theorist who was working on the opposing view to the Big Bang model, called the Steady State hypothesis. In an attempt to show how ridiculous he believed the …premise of the Big Bang theory to be, he coined the term "Big Bang" as an insult to the theory. However, proponents of the theory liked the name, and so adopted it.
The Big Bang suggests that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the u…niverse is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.
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.
The Big Bang Theory present the theoretical premise for the causation, termination, and continuation of an evolutionary expansion of the universe. The Big Bang Theory promotes… four concepts for consideration: 1. that the observable universe is Time bound (or has a finite existence) 2. that the observable universe is expanding (within the dimensional limits of Space and Time), 3. that the observable universe is evolving a set amount of matter and energy while it is expanding over time, and 4. that the observable universe is homogeneous and isotropic with respect to Space and Time.
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.
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. : )
it is the first event of this universe since the time itself started with the big bang! it also created the four fundamental forces of this universe gravitational electromag…netic strong and weak nuclear forces.huge amount of energy is created due to which the universe started to expand and energy inturn created matter which intern created us!!!
The Big Bang theory stems from information collected over the years about the speed and direction the galaxies are moving. Once this information was gathered and examined it a…ppeared that every thing was expanding from a certain point. Not all the matter is moving at the same speed, but if you reverse the direction that everything is expanding from, all the material collects into one big mass. Hence the belief that a Big Bang is responsible for the origin of the Universe. In 1922, Alexander Friedmann noted that the mathematics of General Relativity permit an expanding universe or a contracting universe, but NOT a stable universe. Although Einstein communicated with Friedmann and agreed with his conclusions, nobody made any attempt to connect the math with the actual universe. Georges LeMaitre independently made a similar conclusion in 1927, but ALSO concluded that the Universe we live in must be an expanding one. He also concluded this meant that, at one point, our Universe must have had (his words) "a day with no yesterday"; and made some speculations on physical evidence that would support his viewpoint, including red shifting of distant nebulae. In 1930 Edwin Hubble showed that LeMaitre's predictions of red shift was, indeed, correct.
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.
Like all scientific paradigms, Big Bang Cosmology can change (and has) when new information shows that an earlier idea was incomplete. This does NOT mean that the idea has bee…n falsified (which can happen, but NOT with BBC), only that it has been modified. The largest change in BBC in the last few decades has been the concept of Inflation. Basically, this idea holds that the early Universe had a period when its expansion (*NOT* its explosion) went far more rapidly than what has occurred over the last 13.7 billion or so. Making this assumption resolves two problems that had existed in BBC: why is our Universe so uniform, and why are there no magnetic monopoles? Like all true scientific ideas, Inflation makes predictions about what would be observed when certain experiments were performed. Specifically, the size of perturbations from perfect isotropy in the cosmic microwave background radiation. Recent measurements by WMAP have confirmed that these perturbations exist, and are at the order of magnitude predicted by Inflation Theory.
It was Fred Coyle who gave the term The Big Bang theory.
A spectroscope is an instrument that can be used to observe the frequency (or wavelength) of characteristic spectral lines to see how far the lines were shifted (red shift or …blue shift) from their usual position. All galaxies outside our local galactic cluster produce light that is red-shifted; and the greater the distance between us and these outside galaxies, the greater the red shift. That the size of the red shift depends on the distance is considered isotropic (or the same in all directions), meaning the distance between our local galactic cluster and all other galactic clusters is increasing at the same ratio based on distance from us. These distant galactic clusters, demonstrating red shift, are supportive evidence that these outside galaxies are moving further apart consistent with the Big Bang Theory. Note: The core ideas of the Big Bang is that the Universe was filled homogeneously and isotropically with an incredibly high energy density and huge temperatures and pressures and was very rapidly expanding and cooling.
