    1am Tuesday morning

    No energy is not stuff. Energy is " the ability to do work ie cause a change in in stuff. If stuff is stationary, move it. If stuff is moving stop it. And a few more changes along the same line

    My biggest problem, as well as a gazillion Scientists, how did energy gather itself together into a large region before Big Banging?

    Why was it not dispersed in a nice even manner throughout the good?

    However since it Big Banged and began to cool down it appears much of itself went into making stuff. And as mentioned more stuff then anti stuff

    Stuff becomes different stuff by energy doing more work on it ie pushing stuff it has already made together making the new stuff have more energy content and different properties

    Don't start with the "know" nonsense

    The higgledy piggledy aspect of the Universe (the drunken stagger) has no destination. It is up and running PERIOD

    Will continue to run until it (our Universe) runs no more. Those who claim to know about Universe operations say it will never stop running as it is merely a continuation of its running in the past

    Only the arrangement of stuff changes and the ratio of stuff to energy

    Going to arrange my stuff into back to sleep stuff

    AFAIK all the energy was gathered in a very small region (singularity) before violently dispersing (mega quantum, inflationary epoch event)
    Because it was an uncontrolled violent event (chaos) of pure energy.
    And patterns began to emerge from the chaos in a mathematically self-ordering hierarchy of evolving complexities, until some of what was once pure energy was mathematically transmuted into the stuff we see today.

    p.s. for a small levity

    After this I am out

    pure energy - no such animal

    mathematically transmuted into the stuff we see today

    Think you mean

    physically converted into the stuff seen today

    Quite. Anyone on this forum who tries to resurrect that crap about energy being "stuff", when it has been gone through ad nauseam just recently, must be trolling or just desperate for attention.

    Again, quite so. "Pure energy" is Star Trek, not science.

    We had established that energy itself was not stuff (but had dynamic values), and came before stuff (David Bohm)
    Therefore my original assertion that energy transmuted into stuff was correct. Michael even tried to correct me on the use of the term transmutation.

    Transmutation

    Transmutation refers to the change of one substance into another. It may refer to:
    https://en.wikipedia.org/wiki/Dimensional_transmutation
    No one is except you.
    Or you are completely misunderstanding what is being said. Michael asserted that there is only stuff. Therefore I asked if he thought energy was stuff. The answer is no, to which we all seem to agree.

    I am the one who originally asserted that energy came before stuff.


    Now you come along and sling ad hominems around without even knowing what I am talking about, at fact you have admitted to by claiming I am on ignore and you can only see an occasional partial reference as quoted by someone else. Next time try to inform yourself of what the person is actually saying before you "rush headlong" into a self-created fantasy.

    Why is are you avoiding the highlighted (pertinent) portion about "dimensional transmutation" and cherry pick only that which does not apply in context of the conversation. Stay on topic please.

    We are speaking about the dimensional transmutation from non-physical energy into physical stuff .
    We are in agreement on all points, except that you are ignoring the chronology of the dimensional transmutation, from the state of immeasurable pure dynamical energy (chaos), into a three dimensional object with measurable physical properties (values).

    Is there a difference?

    The point is that energy (non-stuff) came before stuff and stuff came from energy.
    AFAIK , that is just plain old mainstream physics.

    There should be no disagreement on that specific point.

    What is this thing called "stuff"? It is not a term I am familiar with in a scientific context.

    May we have a definition,please?

    Stuff is stuff apart from non-stuff. The term stuff was used to accommodate my lack of scientific knowledge. After all, everyone knows what stuff is.......

    I think it means more or less a substance, or some entity that can be said to have an independent existence. We had a long thread a while ago, trying to explain to some people that energy, like momentum, say, is property of a physical system rather than a substance with an independent existence. In other words, that you can't have a jug of energy, any more than you can a jug of momentum.

    But there it is, the problem with language.

    The problem with a language of physics is, to me, fraught with all kinds of objections, first of all what is a language? Is it something that has a substance, an existence independent of . . . something or other? The word physics is pretty well defined; it's a word you can find in a dictionary, but does it have an existence independent of dictionaries?

    What does independent existence mean anyway? And so on. I see the old saw about being able to put something in a bottle or a jug, is one condition of this independence.

    If I can't put energy in a jug, why do I pay for energy use? I pay whether the energy I use has been wasted or done something useful (although, energy can't really "do" things, right? So that would be a linguistic convention which does not reflect actual physics, right?)

    STUFF is stuff which is tangible and which can be detected and measured

    ENERGY is a PROPERTY of STUFF and is one of the measurements which can be made on stuff

    ENERGY, in its simplest definition is "the ability to do work so "energy can't really "do" things" is incorrect

    This is the best chart I found about the types of energy

    Work (physics) is the action of the energy in stuff used to change the energy in other stuff

    In my opinion, the only language that makes sense in the domain of physics, and which spans both the theoretical and measurable aspects, is physical units.

    That is, metres, seconds, kilograms and coulombs. These are all measurable in some way; without them there is no theory that makes physical sense.
    The notions of substance, materiality, "stuff" and so on are all fine as long as they have physical units.

    Relational mathematical values? The language of physics?

    Physical units are arbitrary (made up concepts)

    Minions did not find a inch or centimetre, or any other measurement laying around waiting to be found

    Measurements were invented and then standardised. A few NUMBERS do appear to be just numbers and 1/137 (B) appears to be such a number

    Seems like this number pops up in many places

    *****

    Note that α is quite a small number, very nearly 1/137. This makes theoretical physicists happy, because it is much easier to calculate things when the forces are not very strong. The theory of radiation and.......
