Bust Nak: So why are you so confident in declaring that time does not physically exist in the universe?
William: For the same reasons as numbers do not physically exist. They don't physically exist.
Bust Nak: But how could you know that, when you don't know what time is fundamentally?
William: The same way as I know that the mind does not physically exist... Point being - all known conceptual properties of the mind are known to exist only in the mind, and are not physically real and can only be represented physically as "unreal but existing anyway" or some such other appropriate entitlement...

Bust Nak: That isn't really answering my question, how could you know time is only a concept if you don't know what it is fundamentally?
It does answer the question.
If we do not know what something
fundamentally is, but still refer to it as
existing, it is conceptual in nature and of the mind.
Things of the mind are
fundamentally unknown. They act as devices which also happen to assist us in understanding the physical universe.
So we use the concept of time, not as a means of understanding what time is [fundamentally] but how it relates to the physical universe.
It may indeed be the case that Physicists are not being careful with their heading and wording. "Doomed" does imply the certainty of death...I am only relaying the basic information. I do my own digging and for now, accept the verdict being pronounced upon spacetime by physicists themselves. If you have contrary information, I am keen to view it.
Well the verdict as it stands now, as it is currently being pronounced, is that time, as part of spacetime, had a beginning but no end.
How is that contrary information?
Please watch the video I posted earlier on in this thread...the one with the visuals of a flyover of the Mandelbrot Set.
It's very pretty, not sure how it shows the apparent beginning of our universe has to be seen as points within infinity.
Fortunately it is not been argued that such
has to be. It is a great visual example of how such might well be.
The points within infinity branch off in their own infinity but are not independent of the whole of infinity, because they branch back to another point from which they derived.
Thus, 'beginnings but not ends" as per "the verdict as it stands now" - pretty as ever...
And "something else" is "all things".
What? All things are derived from all things?
More like all things derive from the one thing which is all things.
If you were that one thing which is all things, what thing would exist outside of/apart from you?
Without energy, what is left to construct and maintain shapeform from the field of quantum particles?
Don't know.
So Energy can also be placed in the fundamentally unknown basket.
You are still not getting to the point. How does heat death imply time stops?
Because ultimately, what it is describing is a return to the previous undisturbed state where the Quantum Field is inert and unaffected because the Energy [whatever it was] has [perhaps] moved on, or alternatively [perhaps] dissipated.
Spacetime, relative to us within it now, and that thing we call "The Universe/Reality": - re the heat-death theory -
if the fundamental property of "Energy" is infinite,
then "Time" derives from Energy, through causing the QF to react and shape objects in that local space being influenced by said Energy...that reaction is "Time" to those within its influence
In this sense, Time is fundamentally Energy, even that fundamentally we do not know what Energy is. We only know that it is responsible for why our universe exists.
"it took a false premise for energy to turn into matter" as energy does not turn into matter. Energy holds the shape of matter. Matter already existed.
Existed? Not immediately after the Big Bang. Where did matter come from if not from energy?
The QF is the matter. Shape came from Energy interacting with QF. The QF didn't 'come from' anywhere. It has always existed.
The real question to ask is where did the
Energy 'come from' and the logical answer may have to be that Energy has also always existed, and did not 'come from' anywhere.
Do you think that "Time" = "Energy"? Or do you think they are separate entities, doing their own separate thing?
No,
You do not think "Time" = "Energy"? You do not think they are separate entities, doing their own separate thing?
energy moves through time.
This implies two separate entities. I think of the process as Energy moving over the QF and the interaction of the influencing Energy disturbs the QF sufficiently to create form, and that reaction is called "Time" by those observing it.
In that sense, Energy is not moving through Time but creating Time by moving through [or over or however it moves in relation to] the QF.
Energy cannot have simply farted itself into existence. Therefore logic informs us that it is likely that energy has existed forever...has always existed. Has never - not existed.
That's fine, but what does existed forever, always existed even mean when time itself had a beginning?
You are conflating our perceptions within Time, with the goings on of Energy. Time begins in relation to those within the
effect the Energy caused. The effect is known as "Time", by us experiencing said effect.
Time is the effect Energy has upon the QT. Both QT and Energy are eternal, whereas time is not, re the interaction. It only lasts for as long as Energy is interacting with QT.
The 'problem' is the idea of a beginning. Rodger Penrose [Sir] sought to solve that by introducing the idea of a spacetimeless moment whereby size didn't exist, therein the Singularity.
This meant that the new singularity [beginning point] - although apparently deriving from an almost impossibly small size - was able to create from that, an almost impossibly large object [spacetime]
William: Is energy separate from matter, or just another manifestation of matter?
Bust Nak:: That's just semantics, if energy counts as object, then your earlier question become invalid, the premise that the was a time when there were no objects, would be false.
William: That depends entirely on the plain of the Quantum field.
For example, if the field is spherical, the energy moving over it and stirring it up into objects of matter, may be no more than a blip on the plain of the Quantum field. Once the energy moves on, the effect on that region diminishes until - once more - the deep silence returns.
Don't understand what you are saying here. Do you think energy counts as an object or not?
We don't know, because we don't have access to that information. Energy could well be an object because it behaves as we observe objects behaving.
However, even if we could zoom out to a perspective where we could view the process from outside of the process, we may still only see the effect of Energy upon the QF, and no visible object at all - we might see the wake, but not the ship making the wake.
Bust Nak:: Why would they have to be fundamentally different though, for some infinities to have a beginning and some not to? Why can't infinites with beginnings and those without be part of an overall infinity?
I am fine with that idea as long as it is agreed there is only - fundamentally - the one Source. The apparent differences are not denoting "many sources".
For what it's worth, I agree that something has always existed.
It is worth a great deal as it is not everyday [hereabouts] folk get on the same page about something.
I think that both QT and Energy have always existed, and are two major aspects/entities of one overall system, which has always existed.
