In , the COBE team announced that they had mapped the primordial hot and cold spots in cosmic background radiation. These spots are related to the gravitational field in the early Universe and form the seeds of the giant clusters of galaxies that stretch hundreds of millions of light years across the Universe.
Mather and George F. With greatly improved resolution compared to COBE, WMAP surveyed the entire sky, measuring temperature differences of the microwave radiation that is nearly uniformly distributed across the Universe.
The picture shows a map of the sky, with hot regions in red and cooler regions in blue. By combining this evidence with theoretical models of the Universe, scientists have concluded that the Universe is "flat," meaning that, on cosmological scales, the geometry of space satisfies the rules of Euclidean geometry e.
Planck is making the most accurate maps of the microwave background radiation yet. With instruments sensitive to temperature variations of a few millionths of a degree, and mapping the full sky over 9 wavelength bands, it measures the fluctuations of the temperature of the CMB with an accuracy set by fundamental astrophysical limits.
How could pieces of the Universe that had never been in contact with each other have come to equilibrium at the very same temperature?
This and other cosmological problems could be solved, however, if there had been a very short period immediately after the Big Bang where the Universe experienced an incredible burst of expansion called "inflation.
Whatever its nature, the inflationary model predicts that this primordial energy would have been unevenly distributed in space due to a kind of quantum noise that arose when the Universe was extremely small.
This pattern would have been transferred to the matter of the Universe and would show up in the photons that began streaming away freely at the moment of recombination.
But all this leaves unanswered the question of what powered inflation. If the redshifts were the result of an explosion from a center distant from us, they would not be so similar in different directions.
Measurements of the effects of the cosmic microwave background radiation on the dynamics of distant astrophysical systems in proved the Copernican principle, that, on a cosmological scale, the Earth is not in a central position.
Uniform cooling of the CMB over billions of years is explainable only if the universe is experiencing a metric expansion, and excludes the possibility that we are near the unique center of an explosion.
In Arno Penzias and Robert Wilson serendipitously discovered the cosmic background radiation, an omnidirectional signal in the microwave band. Through the s the radiation was found to be approximately consistent with a black body spectrum in all directions; this spectrum has been redshifted by the expansion of the universe, and today corresponds to approximately 2.
This tipped the balance of evidence in favor of the Big Bang model, and Penzias and Wilson were awarded a Nobel Prize in The surface of last scattering corresponding to emission of the CMB occurs shortly after recombination , the epoch when neutral hydrogen becomes stable.
Prior to this, the universe comprised a hot dense photon-baryon plasma sea where photons were quickly scattered from free charged particles.
Mather and George Smoot were awarded the Nobel Prize in Physics for their leadership in these results.
During the following decade, CMB anisotropies were further investigated by a large number of ground-based and balloon experiments. In — several experiments, most notably BOOMERanG , found the shape of the universe to be spatially almost flat by measuring the typical angular size the size on the sky of the anisotropies.
In early , the first results of the Wilkinson Microwave Anisotropy Probe WMAP were released, yielding what were at the time the most accurate values for some of the cosmological parameters.
The results disproved several specific cosmic inflation models, but are consistent with the inflation theory in general.
Other ground and balloon based cosmic microwave background experiments are ongoing. Using the Big Bang model it is possible to calculate the concentration of helium-4 , helium-3 , deuterium, and lithium-7 in the universe as ratios to the amount of ordinary hydrogen.
This value can be calculated independently from the detailed structure of CMB fluctuations. The ratios predicted by mass, not by number are about 0.
The measured abundances all agree at least roughly with those predicted from a single value of the baryon-to-photon ratio.
Detailed observations of the morphology and distribution of galaxies and quasars are in agreement with the current state of the Big Bang theory.
A combination of observations and theory suggest that the first quasars and galaxies formed about a billion years after the Big Bang, and since then, larger structures have been forming, such as galaxy clusters and superclusters.
Populations of stars have been aging and evolving, so that distant galaxies which are observed as they were in the early universe appear very different from nearby galaxies observed in a more recent state.
Moreover, galaxies that formed relatively recently, appear markedly different from galaxies formed at similar distances but shortly after the Big Bang.
These observations are strong arguments against the steady-state model. Observations of star formation , galaxy and quasar distributions and larger structures, agree well with Big Bang simulations of the formation of structure in the universe, and are helping to complete details of the theory.
In , astronomers found what they believe to be pristine clouds of primordial gas by analyzing absorption lines in the spectra of distant quasars.
Before this discovery, all other astronomical objects have been observed to contain heavy elements that are formed in stars. These two clouds of gas contain no elements heavier than hydrogen and deuterium.
The age of the universe as estimated from the Hubble expansion and the CMB is now in good agreement with other estimates using the ages of the oldest stars, both as measured by applying the theory of stellar evolution to globular clusters and through radiometric dating of individual Population II stars.
The prediction that the CMB temperature was higher in the past has been experimentally supported by observations of very low temperature absorption lines in gas clouds at high redshift.
Observations have found this to be roughly true, but this effect depends on cluster properties that do change with cosmic time, making precise measurements difficult.
Future gravitational waves observatories might be able to detect primordial gravitational waves, relics of the early universe, up to less than a second after the Big Bang.
As with any theory, a number of mysteries and problems have arisen as a result of the development of the Big Bang theory. Some of these mysteries and problems have been resolved while others are still outstanding.
Proposed solutions to some of the problems in the Big Bang model have revealed new mysteries of their own.
For example, the horizon problem , the magnetic monopole problem , and the flatness problem are most commonly resolved with inflationary theory , but the details of the inflationary universe are still left unresolved and many, including some founders of the theory, say it has been disproven.
It is not yet understood why the universe has more matter than antimatter. However, observations suggest that the universe, including its most distant parts, is made almost entirely of matter.
A process called baryogenesis was hypothesized to account for the asymmetry. For baryogenesis to occur, the Sakharov conditions must be satisfied.
These require that baryon number is not conserved, that C-symmetry and CP-symmetry are violated and that the universe depart from thermodynamic equilibrium.
Measurements of the redshift — magnitude relation for type Ia supernovae indicate that the expansion of the universe has been accelerating since the universe was about half its present age.
To explain this acceleration, general relativity requires that much of the energy in the universe consists of a component with large negative pressure , dubbed "dark energy".
Dark energy, though speculative, solves numerous problems. Dark energy also helps to explain two geometrical measures of the overall curvature of the universe, one using the frequency of gravitational lenses , and the other using the characteristic pattern of the large-scale structure as a cosmic ruler.
Negative pressure is believed to be a property of vacuum energy , but the exact nature and existence of dark energy remains one of the great mysteries of the Big Bang.
Therefore, matter made up a larger fraction of the total energy of the universe in the past than it does today, but its fractional contribution will fall in the far future as dark energy becomes even more dominant.
The dark energy component of the universe has been explained by theorists using a variety of competing theories including Einstein's cosmological constant but also extending to more exotic forms of quintessence or other modified gravity schemes.
During the s and the s, various observations showed that there is not sufficient visible matter in the universe to account for the apparent strength of gravitational forces within and between galaxies.
In addition, the assumption that the universe is mostly normal matter led to predictions that were strongly inconsistent with observations.
In particular, the universe today is far more lumpy and contains far less deuterium than can be accounted for without dark matter.
While dark matter has always been controversial, it is inferred by various observations: Indirect evidence for dark matter comes from its gravitational influence on other matter, as no dark matter particles have been observed in laboratories.
Many particle physics candidates for dark matter have been proposed, and several projects to detect them directly are underway.
Additionally, there are outstanding problems associated with the currently favored cold dark matter model which include the dwarf galaxy problem  and the cuspy halo problem.
The horizon problem results from the premise that information cannot travel faster than light. In a universe of finite age this sets a limit—the particle horizon —on the separation of any two regions of space that are in causal contact.
There would then be no mechanism to cause wider regions to have the same temperature. A resolution to this apparent inconsistency is offered by inflationary theory in which a homogeneous and isotropic scalar energy field dominates the universe at some very early period before baryogenesis.
During inflation, the universe undergoes exponential expansion, and the particle horizon expands much more rapidly than previously assumed, so that regions presently on opposite sides of the observable universe are well inside each other's particle horizon.
The observed isotropy of the CMB then follows from the fact that this larger region was in causal contact before the beginning of inflation.
Heisenberg's uncertainty principle predicts that during the inflationary phase there would be quantum thermal fluctuations , which would be magnified to cosmic scale.
These fluctuations serve as the seeds of all current structure in the universe. If inflation occurred, exponential expansion would push large regions of space well beyond our observable horizon.
A related issue to the classic horizon problem arises because in most standard cosmological inflation models, inflation ceases well before electroweak symmetry breaking occurs, so inflation should not be able to prevent large-scale discontinuities in the electroweak vacuum since distant parts of the observable universe were causally separate when the electroweak epoch ended.
The magnetic monopole objection was raised in the late s. Grand unified theories predicted topological defects in space that would manifest as magnetic monopoles.
These objects would be produced efficiently in the hot early universe, resulting in a density much higher than is consistent with observations, given that no monopoles have been found.
This problem is also resolved by cosmic inflation , which removes all point defects from the observable universe, in the same way that it drives the geometry to flatness.
Curvature is negative, if its density is less than the critical density ; positive, if greater; and zero at the critical density, in which case space is said to be flat.
The problem is that any small departure from the critical density grows with time, and yet the universe today remains very close to flat.
For instance, even at the relatively late age of a few minutes the time of nucleosynthesis , the density of the universe must have been within one part in 10 14 of its critical value, or it would not exist as it does today.
Physics may conclude that time did not exist before 'Big Bang', but 'started' with the Big Bang and hence there might be no 'beginning', 'before' or potentially 'cause' and instead always existed.
Before observations of dark energy, cosmologists considered two scenarios for the future of the universe.
If the mass density of the universe were greater than the critical density , then the universe would reach a maximum size and then begin to collapse.
It would become denser and hotter again, ending with a state similar to that in which it started—a Big Crunch. Alternatively, if the density in the universe were equal to or below the critical density, the expansion would slow down but never stop.
Star formation would cease with the consumption of interstellar gas in each galaxy; stars would burn out, leaving white dwarfs , neutron stars , and black holes.
Very gradually, collisions between these would result in mass accumulating into larger and larger black holes. The average temperature of the universe would asymptotically approach absolute zero —a Big Freeze.
Eventually, black holes would evaporate by emitting Hawking radiation. The entropy of the universe would increase to the point where no organized form of energy could be extracted from it, a scenario known as heat death.
Modern observations of accelerating expansion imply that more and more of the currently visible universe will pass beyond our event horizon and out of contact with us.
The eventual result is not known. This theory suggests that only gravitationally bound systems, such as galaxies, will remain together, and they too will be subject to heat death as the universe expands and cools.
Other explanations of dark energy, called phantom energy theories, suggest that ultimately galaxy clusters, stars, planets, atoms, nuclei, and matter itself will be torn apart by the ever-increasing expansion in a so-called Big Rip.
The Big Bang as the origin of the universe: One of the common misconceptions about the Big Bang model is the belief that it was the origin of the universe.
However, the Big Bang model does not comment about how the universe came into being. Current conception of the Big Bang model assumes the existence of energy, time, and space, and does not comment about their origin or the cause of the dense and high temperature initial state of the universe.
The Big Bang was "small": It is misleading to visualize the Big Bang by comparing its size to everyday objects.
When the size of the universe at Big Bang is described, it refers to the size of the observable universe, and not the entire universe.
Hubble's law violates the special theory of relativity: Hubble's law predicts that galaxies that are beyond Hubble Distance recede faster than the speed of light.
However, special relativity does not apply beyond motion through space. Hubble's law describes velocity that results from expansion of space, rather than through space.
Doppler redshift vs cosmological red-shift: Although similar, the cosmological red-shift is not identical to the Doppler redshift.
The Doppler redshift is based on special relativity, which does not consider the expansion of space. On the contrary, the cosmological red-shift is based on general relativity, in which the expansion of space is considered.
Although they may appear identical for nearby galaxies, it may cause confusion if the behavior of distant galaxies is understood through the Doppler redshift.
While the Big Bang model is well established in cosmology, it is likely to be refined. The Big Bang theory, built upon the equations of classical general relativity, indicates a singularity at the origin of cosmic time; this infinite energy density is regarded as impossible in physics.
Still, it is known that the equations are not applicable before the time when the universe cooled down to the Planck temperature , and this conclusion depends on various assumptions, of which some could never be experimentally verified.
Also see Planck epoch. One proposed refinement to avoid this would-be singularity is to develop a correct treatment of quantum gravity.
It is not known what could have preceded the hot dense state of the early universe or how and why it originated, though speculation abounds in the field of cosmogony.
Proposals in the last two categories see the Big Bang as an event in either a much larger and older universe or in a multiverse. As a description of the origin of the universe, the Big Bang has significant bearing on religion and philosophy.
