The most impressive conclusions are often reached when people try to rule out possibilities or to confirm conservative theories, and then they find that it does not work and that the facts force them to change their minds. Unfortunately, this program hits major snags. So it seems there is a difference of a factor of a billion. Please clarify. Great article. One also assumes that the universe looks the same everywhere and in any direction. This allows the creation of particle-antiparticle pairs of virtual particles.

  • Quantum Fluctuations and Their Energy Of Particular Significance

    In quantum physics, a quantum fluctuation is the temporary change in the amount of energy in a. Kennedy, James (Jim) E. "Nature and Meaning of Information in Physics". Retrieved 22 April ^ Mani Lal Bhaumik (4. Quantum fluctuation is the temporary appearance of energetic particles out of nothing, as allowed by the Uncertainty Principle.

    It is synonymous with vacuum. quantum-fluctuation definition: Noun (plural quantum fluctuations) 1. (physics) A momentary fluctuation in the energy at a point in space due to the Heisenberg.
    Vacuum energy may also be responsible for the current accelerating expansion of the universe cosmological constant.

    Do Quantum Fluctuations Show that Something Can Come from Nothing – Neil Shenvi – Apologetics

    Somewhat late to chime in here, but I will anyway. From what I found, the answer to this is not so straight-forward that it can be put in one sentence. You are commenting using your Facebook account. Remember the atom is emptier, relatively speaking, than the solar system. These articles of yours are just great.

    Dark energy has to deal with the acceleration of the expansion of the universe, and not having an energy source that is measured to account for this acceleration. Regarding arXiv Blog at WordPress.

    Gravity for ex. Thus, only a tiny tiny tiny fraction of imaginable universes would even vaguely resemble our own or at least, the part of our own that we can observe with our eyes and telescopes.

    An aside: in quantum field theory, quantum fluctuations are sometimes *By definition*, dark energy is something that does not “weaken” as.

    I hope, he does not mind my trying to answer this one. As universe expands with constant vacuum energy density ,internal energy has to increase because of increase in volume there is more vacuum!

    Regarding shear stress: In this context I think it is more natural to think of it as flow of momentum, e.

    Is the point, that due to the Heisenberg uncertainty principle, one cannot precisely determine the value of the field at a given point and as such its standard deviation is non-zero. Marko, Many thanks for the link.

    Physics would lose nothing if we all just agreed to stop using that word.

    Just google if you are interested. An extension is applicable to the "uncertainty in time" and "uncertainty in energy" No, it's not.

    Matt, I am sorry if my comments came across as definitive, confident, bald in errors or such.

    1. I agree. One example: quantum fluctuations are known to cause the strengths of forces to drift as you measure them at shorter and shorter distancesand not only do we observe such drift in data, what we observe matches, to high precision, with what we calculate using the Standard Model.

    2. I am not sure it will necessarily help you explain things to the others in this thread. Any thoughts on this?
