The speed of light is a local result, it pertains to the speed of light in a flat spacetime or a small region where any curvature is insignificant. The fact that we have several independent lines of evidence supporting the theory, coupled with the fact that the physics is well understood even back to just after the BB gives us a fair degree of confidence that we are on pretty much the right track. Erickcek and her colleagues argue that the asymmetry could be the remnant of fluctuations in an additional energy field, which started out very tiny, but were blown up by inflation until they were larger than the observable universe. The asymmetry could theoretically be explained by the standard, single-field inflation scenario, though researchers say that is unlikely. One moment. You have free article s left.

  • The best answer is that not only do we not know what is going on outside of our observable universe, but we simply can't know what happens.

    Hundreds of clusters of galaxies are streaming en masse towards a region at the edge of the visible universe. The discovery has taken.

    Colossal structures larger than the visible universe – forged during the period of cosmic inflation nearly 14 billion years ago – may be.
    Intermediate What will happen to Earth's tides as the moon moves away from us? Inflation solves some cosmological puzzles, such as why relic radiation from the big bang, released when the universe was less thanyears old, is relatively uniform.

    [astroph/] On the Fractal Structure of the Visible Universe

    Beginner Is the Moon moving away from the Earth? For example the event horizon is a membrane where a photon on it is held fixed and has zero speed. There is a lot of conjecture in any perhaps all cosmological hypotheses. The Big Bang, instead of being a singularity, is the set of initial conditions of an extremely hot, dense, expanding Universe that exists immediately after the end of inflation.

    Yeah, physics is not made to be imaginable.

    It depends on how fast the Hubble radius itself is decreasing in comoving coordinates, which is a function of the cosmological parameters.

    Or — assuming a model, what is the relative probability that the data comes about as a result of the modeled physics or by chance alone? Depending on how quickly the ground was expanding, you may have run tens of kilometers instead of just a few meters — even if you were running at a set speed.

    Some replies dance around Occams Razor; that within several plausible explanations for a particular hypothesis, the simpler explanation is usually the correct one.

    A photon emitted from an object beyond the Hubble radius, one that starts out in our direction but is receding from us due to the expansion of the space-time between, can eventually cross over into our Hubble volume and then eventually reach us.

    Yes, the term "visible universe" refers to the fact that the actual universe might be bigger than the part of it we can see (in fact, it might be infinitely big). The part. The observable universe is about 93 billion light-years across.

    These simplest wave forms hold their shape as they propagate. Acceleration is downward on the rubber sheet and outward on the torus. Or, is it that the space between is expanding, but the starting point is not necessarily moving at all?

    The conclusion, if correct, would shatter a cherished assumption about the universe. Stars disperse into gas, which gradually smooths itself out through space; matter as a whole continues to move together and grow more dense.

    High-intensity radiation suddenly sweeps in from across the universe, in a spherical pattern focused on a point in space.

    Intermediate What makes certain lunar eclipses so special? Erickcek and her colleagues argue that the asymmetry could be the remnant of fluctuations in an additional energy field, which started out very tiny, but were blown up by inflation until they were larger than the observable universe. The white hole gradually grows to billions of times the mass of the sun, through accretion of additional radiation of ever decreasing temperature.

    The temperature differences are thought to be caused by variations in the density of matter, with denser regions being warmer than emptier regions.

    That is a whole other bag of physics.

    This is the surface in our visible universe which bounds the region where dark energy dominates the expansion, and within which the universe is accelerating. The distribution of luminous matter in the universe is therefore fractal and not homogeneous.

    The evidence for this being very strong up to h^{-1}Mpc due to. The scale of the Universe is impossible to imagine (Credit: Denys Bilytskyi/Alamy The observable Universe is, of course, much larger.
    Was there a singularity before inflation?

    Intermediate Why can't a plane fly slowly and let the Earth pass underneath? If you want to have some clear idea about these matters please do this. For anything that is farther away, the light from it would not yet have had a chance to get here.

    If we wound the clock of the Universe backwards, we would discover something remarkable.

    No longer could we extrapolate all the way back to a singularity.

    Here is a timeline of important events in the history of our observable universe, according to conventional cosmology: Space is empty, featuring nothing but a tiny amount of vacuum energy and an occasional long-wavelength particle formed via fluctuations of the quantum fields that suffuse space.

    When was this discovered? As a result, the value of this energy field varied from one side of the universe to the other at early times, enhancing the variations in temperature — and matter density — on one side of the sky relative to the other. First, if you look from the viewpoint of theory, it is simpler to use infinities.
