WebAccording to Big Bang theory, the radiation contained information on how matter was distributed over ten billion years ago, when the universe was only 500,000 years old. At that time, stars and galaxies had not yet formed. The Universe consisted of a hot soup of electrons and atomic nuclei. In the decades since the detection of cosmic microwave background (CMB) in 1965, the Big Bang model has become the most accepted model explaining the evolution of our universe. The Friedmann equation defines how the energy in the universe drives its expansion. where κ represents the curvature of the universe, a(t) is the scale factor, ρ is the total energy density of the universe, and H is the Hubble parameter.
WebMay 23, 2002 · Accelerating Universe: Theory versus Experiment. Moshe Carmeli. We present gravitation as a theory in which the coordinates are distances and velocities between galaxies. We show that there are three possibilities for the Universe to expand: decelerating, constant and accelerating, and it is shown that the Universe is now in the …
WebSep 17, 2002 · If the Linde-Kallosh model is correct, then the universe, which appears to accelerating now, will begin to slow down and contract. "The universe may be doomed to collapse and disappear," Linde said. WebInflationary Universe Theory The Inflationary Universe Theory proposes a brief period of extremely rapid accelerating expansion in the very early universe, before the radiation dominated era called the hot big bang. This acceleration is believed to be driven by a quantum field (in effect, some exotic kind of matter) with a repulsive gravitational effect.
