Review of Short Phrases and Links

    This Review contains major "Universe"- related terms, short phrases and links grouped together in the form of Encyclopedia article.


  1. The universe is a cosmic egg that cycles between expansion and total collapse. (Web site)
  2. The universe is a big place, perhaps the biggest. (Web site)
  3. Universe - The Cosmology Quest is a unique mixture of a human interest and science documentary film.
  4. The Universe is only a portion of the Multiverse.
  5. Universe: The Cosmology Quest is the definitive video for those interested in plasma cosmology.


  1. At the time, physicists were prejudiced to believe in a perfectly static universe without beginning or end.
  2. Einstein added a cosmological constant to his theory to try to force it to allow for a static universe with matter in it. (Web site)
  3. The solution is an expanding universe; due to this expansion the radiation and matter in the universe are cooled down and become diluted. (Web site)
  4. Thus with the expansion of the universe radiation becomes less dominant than matter.
  5. In 1931, Georges-Henri Lema--tre set out a theory that has since come to be called the Big Bang theory of the origin of the universe.

Ultimate Fate of The Universe

  1. There are many possible solutions to the equations of general relativity, and each solution implies a possible ultimate fate of the universe. (Web site)
  2. For religious beliefs and other common beliefs regarding the ultimate fate of the universe, see eschatology.

Expands Forever

  1. Even without dark energy, a negatively curved universe expands forever, with gravity barely slowing the rate of expansion. (Web site)
  2. Hence cosmologists aimed to determine the fate of the universe by measuring --, or equivalently the rate at which the expansion was decelerating. (Web site)
  3. Absent dark energy, a flat universe expands forever but at a continually decelerating rate, with expansion asymptotically approaching some fixed rate. (Web site)
  4. Open universe If -- open, i.e., negatively curved like the surface of a saddle.


  1. In general, the universe can have three different kinds of geometries: hyperbolic geometry, Euclidean geometry, or elliptic geometry.
  2. Friedmann universe of hyperbolic space Alexander Friedmann 1924 Hyperbolic expanding space. (Web site)


  1. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will not collapse. (Web site)
  2. Whatever the ultimate fate of our universe may be, almost all parallel universes will have different fates.
  3. From top to bottom: a spherical universe, a hyperbolic universe, and a flat universe. (Web site)
  4. Davies takes several theories and then logically extrapolates the possible fates of the universe.
  5. This creates three possible ultimate fates of the universe, depending on whether -- is equal to, less than, or greater than 1.

Evidence Began

  2. With dark energy, the expansion rate of the universe initially slows down, due to the effect of gravity, but eventually increases. (Web site)
  3. These arguments caused cosmologists to abandon the oscillating universe model. (Web site)
  4. The homogeneous and isotropic universe allows for a spatial geometry with a constant curvature. (Web site)
  5. The Heat Death scenario is compatible with any of the three spatial models, but requires that the universe reach an eventual temperature minimum. (Web site)

Local Geometry

  1. In a flat universe, all of the local curvature and local geometry is flat. (Web site)
  2. The local geometry is the curvature describing any arbitrary point in the observable universe (averaged on a sufficiently large scale). (Web site)


  1. Formally, the question of whether the universe is infinite or finite is whether it is an unbounded or bounded metric space. (Web site)
  2. Depending on the geometry and topology of the universe, a given geodesic may continue forever, but the universe could still be bounded.

Big Freeze

  1. The Big Freeze is also known as the heat death of the universe.
  2. The Big Freeze is a scenario under which continued expansion results in a universe that is too cold to sustain life. (Web site)

Digital Universe

  1. Since then, the evolution of the universe has passed through three phases. (Web site)
  2. Observations suggest that the universe as we know it began around 13.7 billion years ago.
  3. This led the majority of cosmologists to accept the Big Bang, in which the universe we observe began a finite time ago.
  4. The so-called Einstein universe is, however, unstable.
  5. In our universe this has already happened, billions of years ago.

Universe Expanding

  1. Given the cosmological principle, Hubble's law suggested that the universe was expanding. (Web site)
  2. The history of the universe is a central issue in cosmology. (Web site)
  3. The quark-gluon plasma which composes the universe cools until hadrons, including baryons such as protons and neutrons, can form.
  4. Understanding this period of the history of the universe is one of the greatest unsolved problems in physics.
  5. From then on, the beginning of the universe and its possible end have been the subjects of serious scientific investigation. (Web site)
