Ask an Astronomer, Cornell University. In particular, the universe today is far more lumpy and contains far less deuterium than can be accounted for without dark matter. Main articles: Galaxy formation and evolution and Structure formation. Retrieved 30 January In either case, "the Big Bang" as an event is also colloquially referred to as the "birth" of our universe since it represents the point in history where the universe can be verified to have entered into a regime where the laws of physics as we understand them specifically general relativity and the standard model of particle physics work. Mather and George Smoot were awarded the Nobel Prize in Physics for their leadership in these results. TV : Terminus.
What Happened Before the Big Bang Vídeo Dailymotion
This episode of the science series explores a dizzying world of cosmic bounces, rips and multiple universes, and finds out what happened before the big bang. Professor Smolin's interpretation of what happened before the Big Bang.
Professor Lee Smolin from the Perimeter Institute gives his theory on. In many ways, it's strange to us humans that the Universe should be the age it is. The Universe – by definition, everything that physically exists.
Cambridge Cosmology: Hot Big Bang.
In this model the universe is roughly the same at any point in time.
A few minutes into the expansion, when the temperature was about a billion one thousand million kelvin and the density was about that of air, neutrons combined with protons to form the universe's deuterium and helium nuclei in a process called Big Bang nucleosynthesis.
Religious interpretations of the Big Bang theory.

Introduction to cosmology. This issue was later resolved when new computer simulations, which included the effects of mass loss due to stellar windsindicated a much younger age for globular clusters.
Science Documentary hosted by Bernard Hill, published by BBC n. 3. Before the Big Bang there was no space or time.

So, it is actually meaningless to ask what caused the Big Bang to happen – there was no Universe in which that.
Ask an Astronomer, Cornell University. Indirect evidence for dark matter comes from its gravitational influence on other matter, as no dark matter particles have been observed in laboratories. 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.
Retrieved 13 November Before this discovery, all other astronomical objects have been observed to contain heavy elements that are formed in stars.
Archived from the original on 4 July Scientific American.
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. 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.
General relativity describes spacetime by a metricwhich determines the distances that separate nearby points.
