    The De Broglie - Bohm Pilot wave hypothesis is also called Bohmian Mechanics and solves the inherent problems contained in the Copenhagen Interpretation.

    Write4U , here's the thing ;

    Eliminate all matter and plasma energy in the Universe , hence there is no internal energy in space , where does this fabric of space come from ?

    Of course, this is impossible even as a thought experiment. You can't change the universe at whim and then ask if it's different.

    The point Dave was to understand what the " fabric of space " actually is . Not mathematically but physically .

    Well, this may explain;
    https://physics.aps.org/articles/v6/111

    Thus the fabric of space is a "field", the Higgs field.

    It does not explain the fabric of space .

    The so called " fabric of space " always has an object in space .

    Why must that be so?
    Is a field an object or is "all of space is filled with a field that interacts with (massless) weak force (virtual) particles to give them mass" ?

    Because space is from the object and the object is space . Both manifest simultaneously .

    The field is from the object . The field is the consequence of the object itself .

    What if the object (and thus the field) is massless?

    Then that is the same as nothing . Which then means it does not exist and never will .

    Of course there is energy , light energy .

    And of course light comes from an object(s) IN space .

    Can someone define what space is?
    Is the place where bodies are found?
    Is the set of bodies and energy in the universe?
    Is the space infinite?

    For Philochrony, time is the relation between two sequential states in becoming.
    Becoming flows, time cuts it. For example, 12 midnight is a cut.

    if i recall correctly higgs was determined by averaging the values of hundreds or dozens of lhc collision events.
    Somewhat sketchy looking possibly. Eventually the mass was assumed to be 125 gev.

    this whole idea that higgs give things mass is beyond me actually and doesn't make sense from a rational perspective.

    are you saying that without higgs, molecules structures would simply be ghosts and travel through each other without collisions?

    it is understandable to say that higgs somehow causes gravity.
    but mass is more than gravity,
    mass is the very collisions themselves, the shape and structure itself, the density itself.

    If something has no density then it does not exist, light goes through it, etc, cannot be detected by anything, it does not exist.
    surely it is easier to say that higgs is first cause, giving birth to matter itself. why use wordage calling it "giving mass" when it might as well be what is creating everything in totus.

    A photon has no mass but it carries energy. Gravitational lensing shows that it interacts with gravity as well.

    Atoms would still be massive even without the Higgs. Most of the mass in an atom is due to the strong force binding the protons (and their kinetic energy) together. Even if quarks and electrons were without mass, an atom would still have most of its mass. Only about 2% of an atom's mass comes from the Higgs.

    As I understand it (in a very limited way), one could compare it to a particle traveling in a sticky medium and picking up some of the sticky stuff as it passes. A kind of snowball effect?

    Getting back to the original question for a second, let me ask...does time exist if there is no change possible?

    Supposedly our Universe is expanding and eventually there will not be enough mass for stars to form so once all stars "die" there won't be a whole lot going on. If there is nothing going on (no change) in what sense can one say that time exists?

    Did Einstein not address that in his "riding a beam of light" thought experiment, where passage of time becomes meaningless?

    IMO, time is a result of change. Thus, no change, no aging....time becomes a meaningless property.

    And as you know my stand - change between two arbitrary moments is AGE -- AGE is not TIME

    If I understand you, when something does not age it is not subject to time? Or can something not age but is still subject to time?
