    You have a long history of talking about things of which you know nothing. And you can't be bothered to learn.
    And then - when presented with facts - you "disagree", even though you don't know better.
    This is an irresponsible waste of other peoples' time.

    If you're interested in science, do us the courtesy of educating yourself just a bit. If you don't wish to educate yourself, then you have no business disagreeing.

    The Big Bang was not an explosion, it was a rapid expansion. Accept that fact. Or go get educated.

    Rapid expansion , as a fact , no problem , it still loses energy .

    It doesn't. It distributes energy over a larger volume. But the total amount of energy does not change.

    If I pour a bucket of paint on the floor, and spread it around, it will look thinner and thinner as I spread it. The paint gets distributed over a larger area, but the total amount of paint doesn't change.

    True

    But the energy within the paint becomes less . And its coverage comes to a point of zero .

    Which is why the analogy breaks down here - and paint has jack all to do with the big bang. That said, the total amount of energy before and after is constant...

    So the energy before and after BB is constant ? Why ?

    0 --> alpha and omega. Where do we go from there?

    To what you mean , in words .

    Explain in more depth .

    Anyway it is the material IN space that bends , not space its self .

    Space is the consequence of energy and matter , existence .

    ( Energy micro , sub-quantum ; needing the lowest amount of space to exist and Galaxies macro needing the largest amount of space needed to exist ).

    Because we are talking about the total amount of energy in the universe.

    No matter how much you spread the paint around - there isn't any less paint.

    You haven't told me why .

    Expansion , in the end becomes less energenic . Because it starts as a focus point , spreading out . Therefore the cooler it becomes .

    There is more energy in the begining .

    Anyway , space can never bend .

    Because space has no properties in and of its self .

    Without energy nor matter , space would not exist .

    Space in and of its self , cannot create space without a physical object existing first .

    This much is true. Space is not a thing that bends.

    It is the geometry of spacetime that has curvature.

    If I start with a gallon of paint and paint the floor of a giant warehouse, spreading it as thin as possible, how much paint - in gallons - is there on the floor once I'm done?
    A gallon? Or none?

    Yes.

    What is confusing you is the difference between a total amount of energy of the system and energy per unit volume.

    The total amount of energy remains the same, but if we measure a given volume (say, a cubic light year), the energy of that volume decreases, as the universe expands.

    True to your first statement .

    To your second , statement , Therefore more mathematical than physical .

    If you throw a ball in the air, it arcs up and then back down to hit the ground.

    That is the curvature of spacetime.

    Is it your assertion that the parabolic arc of that ball is not physical? ' cuz to me that seems about as physical as you can get.

    Response to the highlighted .

    Exactly , nothing more , nothing less .

    Mathematics in space by the presence of a physical object , with momentum , in moment .
