- The Hubble volume is approximately 10 31 cubic light years.
- In principle, it would be impossible to scientifically verify an identical Hubble volume.
- In regard to configurations such as the distribution of matter, almost all will differ from our Hubble volume.
- This follows directly from the cosmological principle, wherein it is assumed that our Hubble volume is not special or unique.
- Accordingly, an infinite universe will contain an infinite number of Hubble volumes, all having the same physical laws and physical constants.
- Given infinite space, there would, in fact, be an infinite number of Hubble volumes identical to ours in the universe.
- Tegmark argues that a Level III multiverse does not contain more possibilities in the Hubble volume than a Level I or Level II multiverse.
- However, because there are infinitely many, far beyond the cosmological horizon, there will eventually be Hubble volumes with similar, and even identical, configurations.
- If space is infinite, or sufficiently large and uniform, identical instances of the history of Earth's entire Hubble volume occur every so often, simply by chance.
- In effect, all the different " worlds " created by " splits " in a Level III multiverse with the same physical constants can be found in some Hubble volume in a Level I multiverse.
- It's difficult to see hubble volume in a sentence .
- Hubble radius, Hubble sphere, Hubble volume, or Hubble horizon is a conceptual horizon defining the boundary between particles that are moving slower and faster than the speed of light relative to an observer at one given time.
- :: : : Actually I think the fuzzball picture is probably correct, because black hole complementarity requires the existence of an exterior theory of black holes in which everything does go splat at the horizon, and a similar theory for every Hubble volume.
- In cosmology, a "'Hubble volume "', or "'Hubble sphere "', is a spherical region of the 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.
- The section of spacetime that can be observed is the backward light cone ( all points within the cosmic light horizon, given time to reach a given observer ), while the related term Hubble volume can be used to describe either the past light cone or comoving space up to the surface of last scattering.
- The proportion of barred spirals relative to their barless cousins has changed over the history of the Universe, with only about 10 % containing bars about 8 billion years ago, to roughly a quarter 2.5 billion years ago, until present, where over two-thirds of the galaxies in the visible universe ( Hubble volume ) have bars.
- In August 2010, researchers from the University of New South Wales, Swinburne University of Technology, and Cambridge University published a paper titled " Evidence for spatial variation of the fine structure constant ", whose tentative conclusion is that, " qualitatively, [ the ] results suggest a violation of the Einstein Equivalence Principle, and could infer a very large or infinite universe, within which our'local'Hubble volume represents a tiny fraction ."
- Cosmologists such as professor Alexander Vilenkin from Tufts University and Massachusetts Institute of Technology professor Max Tegmark suggest that if space is sufficiently large and uniform, or infinite as some theories suggest, and if quantum theory is true such that there is only a finite number of configurations within a finite volume possible, due to Heisenberg's uncertainty principle, then identical instances of the history of Earth's entire Hubble volume occur every so often, " simply by chance ".
