Difference between Observable universe and Speed of light

Observable universe vs. Speed of light

The observable universe is a spherical region of the Universe comprising all matter that can be observed from Earth at the present time, because electromagnetic radiation from these objects has had time to reach Earth since the beginning of the cosmological expansion. The speed of light in vacuum, commonly denoted, is a universal physical constant important in many areas of physics.

Similarities between Observable universe and Speed of light

Observable universe and Speed of light have 23 things in common (in Unionpedia): Causality (physics), Chronology of the universe, Diameter, Earth, Electromagnetic radiation, Expansion of the universe, Gamma-ray burst, General relativity, Gravitational constant, Hubble volume, Isotropy, Light, Light-year, Observable universe, Outer space, Parsec, Photon, Quasar, Radius, Spacetime, Special relativity, The New York Times, Universe.

General relativity

General relativity (GR, also known as the general theory of relativity or GTR) is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.

Gravitational constant

The gravitational constant (also known as the "universal gravitational constant", the "Newtonian constant of gravitation", or the "Cavendish gravitational constant"), denoted by the letter, is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's general theory of relativity.

Hubble volume

In cosmology, a Hubble volume or Hubble sphere is a spherical region of the observable universe surrounding an observer beyond which objects recede from that observer at a rate greater than the speed of light due to the expansion of the Universe.

Isotropy

Isotropy is uniformity in all orientations; it is derived from the Greek isos (ἴσος, "equal") and tropos (τρόπος, "way").
