A dimension filled with time, or a physical permission which allows for chronology of events and the emergence of an associated time line?

I see this as saying that "heat" is a seperate dimension where heat dwells. Of course this is not true. Heat has no independent existence apart from friction. And so does time not have an independent existence apart from change.

Is it not more correct to say that heat is an emergent measurable byproduct of friction and that time is an emergent measurable byproduct of change?

Time is a product of all living things.

Actually, Write4u, that's exactly what I'm saying. Potential does not actually exist, it's what could be.

It seems to me the question is this: why doesn't light traverse time, to the beginning? If travelling the speed of light reverses time, we must assume such a velocity still exists in the absence of light, so that when light travels so, it acts in reverse.

You're assuming only light can travel at that speed.

I agree. Time is an emergent property of all change. Without change there is no measurable time. Without time there is no measurable change.
Potential = That which may become reality.
Don't we receive light from the BB, the beginning?
I believe the equation say that time becomes immeasurable at the speed of light. Einstein's riding a light beam show reality as "standing still" without change and thus without time.
It is a universal constant.
However;

We can summarize the problems brought by Einstein's thought experiment to an emission theory:

I see heat as an expression of potential "energy" emerging from an unstable prior state or by the interaction of physical objects.

I believe this addresses the problem from a different perspective, but which nicely illustrates the "emergence" of spacetime from nothing, during the event of the BB.

Spacetime emerging from "nothing"! All subsequent physical patterns have emerged from the inherent potentials of spacetime.

Evolution = Beneficial qualities emerging from enfolded potential abilities. ("hierarchies of expression", David Bohm)

Something cannot come from nothing. If there was nothing, there will be nothing forever...

Yes. Heat is the kinetic energy of the random motion of atoms and molecules. "Potential" does not come into it.

And the definition of evolution is rubbish too, suggesting, as it does, some sort of goal or purpose for which there is no evidence.

Been holiday
No internet on return
Just back up and running

From reading the waffle say the last 100 odd post

Reads like a can of exploded spaghetti

I cannot see a single piece of evidence

Will wait

Meanwhile will rest from holiday ready for next one in 6 weeks and take a bet not a single piece of evidence will appear before 1 December

Potential in this context is very much a factor.

https://en.wikipedia.org/wiki/Match

Matches have the potential for starting fires, even when still in the match box!

Definition; Potential, an inherent excellence which may become expressed in reality.
No motivated goals, as I made abundantly clear in previous posts. In my universe all functions are regulated by mathematical permissions and restrictions of the physical and dynamical potentials present and affecting the outcome.

This gets a little special attention

Since my position is TIME DOES NOT EXIST

how would you like me to prove something which is none existent?

Just curious

BINGO again.

This is your usual confusing of the general meaning of the term "potential" with its more restrictive and precise meaning in physical science, in the context of energy. Several people, including me, have tried over the years to clarify the distinction for you, but you can't grasp it. I'm not going through this again. You have obviously decided it suits your purpose to talk crap. There's not much any of us can do about that.

Oh, I grasp, and I have many times stipulated that the generic term "potential" is applicable to all "enfolded" properties, which may become "unfolded" in reality. I use several terms in the broadest possible context. I do have access to various definitions, in case you believe I just pull this stuff out of thin air.

Unrealized Potential is a "common denominator" of all things in the universe and it is nice to be able to identify common denominators. It saves time and endless explanations......

If you want to restrict your definitions to only what sets each potential apart from the others, then you're practicising fractured science, precisely what David Bohm rejected as it results in refusal to look at and understand the "Wholeness" principle.

Potential energy is not in any way "unrealised" or "enfolded". That is meaningless crap.

It is energy, just as real as kinetic or thermal energy. Potential energy is energy that is present due to a configuration of the system, a change in which will cause transformation to another form of energy.

But I don't know why I bother.

Michael345, if time does not exist then how do you explain the continuous time-line I have shown in the above example? Z-N. It could be a series of "nows" (present moments) I suppose, however I believe in TIME (when you haven't died.)

Also, if life happens like that naturally then how do you explain the moment the decision is made (afterwards?)

As I've stated, without action nothing happens. It doesn't happen automatically: you must act, and the decision isn't made until afterwards.

Maybe you can learn something...

A mountain lake has potential for generating energy. It doesn't have energy, but if you run the lake water downhill and let the kinetic energy turn a turbine, you can generate energy that was not there before. The potential energy was "enfolded" in the water of the lake and can be "unfolded" as energy with some manipulation of environment.

The potential for energy was contained in the mountainlake, due to its location and gravitational forces.

So, to you, a mountain lake "doesn't have energy". Yet you quote in support a source that tells you, quite explicitly, that potential energy is a type of energy.

To you, then, energy just appears, from something that does not have any. So that's the end of the principle of conservation of energy, right?

And you wonder why people like me think you talk out of your arse.

What you have done is what you always do: confuse the general or literary meaning of "potential", which indeed can mean something latent or unexpressed, with the specific meaning of "potential energy" in physical science, which is what I told you it was in post.155.

You do this all the time, but especially with the words "potential", "function" and "value", in spite of having had this pointed out to you repeatedly. I believe you do it deliberately, as it helps you to formulate the theology of your strange religion, which worships mathematics as the Creator. I think it's a kind of cargo cult: you worship what you do not understand.

Whatever it is, it is not science and often makes what you say ridiculous.

I see no conflict.The lake has no expressed energy, it has potential (unexpressed energy). Read the definition.
Does the rock sitting still at the ledge have energy? If it falls it will have energy, but until it does fall it has no "expressed" energy, it is stationary. It's potential energy is contained and latent while it is stationary.
Because you have limited vision.
OK, finally you admit I was not wrong, but "confused". You did overlook the qualifier posed many pages ago, that I am not specifically speaking about the definition in physics, but in the broadest generic meaning. You missed that and came to a knee jerk conclusion.
OK, continue with you ad hominem. Typical response of an ignoramous.
So we have come to the point where you admit that logically speaking I am right but I don't know why I am right, because in your narrow perspective there is only the scientific definition which is pertinent under all circumstances.

I am using the term "potential" correctly in context of the discussion.

What you fail to see is that I look at the term potential and it's myriad of definitions and see an underlying "common denominator". A fundamental premise contained in all the definitions of the term potential.

Webster;
In science, however, the adjective has a special meaning: Potential energy is the kind of stored energy that a boulder sitting at the top of a cliff has (the opposite of kinetic energy, which is what it has as it rolls down that cliff).

LATENT, DORMANT, QUIESCENT, POTENTIAL mean not now showing signs of activity or existence. LATENT applies to a power or quality that has not yet come forth but may emerge and develop. a latent desire for success DORMANT suggests the inactivity of something (such as a feeling or power) as though sleeping. their passion had lain dormant QUIESCENT suggests a usually temporary cessation of activity. the disease was quiescent POTENTIAL applies to what does not yet have existence or effect but is likely soon to have. a potential disaster

Did You Know?
Potential can be either good or bad. Studying hard increases the potential for success, but wet roads increase the potential for accidents. But when a person or thing "has potential", we always expect something good from it in the future. As an adjective (as in "potential losses", "potential benefits", etc.), potential usually means simply "possible". In science, however, the adjective has a special meaning: Potential energy is the kind of stored energy that a boulder sitting at the top of a cliff has (the opposite of kinetic energy, which is what it has as it rolls down that cliff).

Examples of potential in a Sentence
