Can you answer the most fundamental question about time?

" Something does not need to be physical to be real "

In the energy and matter , Universe , yes it does .

You need to quote the entire statement.

Seems my position is not that controversial.....

IMO, the essence of space is of a mathematical nature. The mathematical interactions of "relative values" and mathematical "algebraic functions".

I would agree with that. But energy maybe no more than the result of a dynamical environment.

Renate Loll et al propose a theory of Causal Dynamical Triangulation (CDT)

AFAIK, this proposal includes a fractal function at 2D Planck scale. This is a serious hypothesis and subject to vigorous discussion in the world of cosmology.

Space without energy .

Can space exist in and of its self ?

No physical things are the essence of space . Space can exist without any thing physical existing .

If so how ? How does space exist with no physical properties ?

 

I read the whole statement, and the addition does not detract from the fact that time and space are interchangeable or analogously two sides of the same coin..."some physicists" say that space may give rise to time. And I didn't say your position was controversial.

No it doesn't. Space is real..it is not physical...time is also thought of as real by many physicists...but again it isn't physical.

A few points from the video...Time more fundamental then space and space and time on an equal footing or interchangeable.

 

So how did space become ?

Without anything physical being implied ?

 

Let me try to paint an image.

Not to be confused with Space (mathematics).

You've been told this also river. We do not know the how or why space and time [spacetime/universe] arose. Perhaps a fluctuation in the quantum foam, among many other fluctuations.
We can only speculate back further then T+10-43 seconds.
But obviously some nuts then like to interpret that as a weakness and substitute a "god of the gaps" or some other unsupported, superfluous scenario.

 

Without anything physical existing , both space and time would not exist .

 

Wrong actually, but I'll stand corrected if you have a reference?
Certainly energy exists within space.

 

Actually , explain " Wrong actually " .

 

Sure! Because prior to the decoupling of the superforce, matter nor anything physical actually existed.
But then as the four forces decoupled, gravity being the first, and as gravity within GR is spacetime geometry, then the energy present explains that spacetime curvature/geometry. Then of course "physical matter"[if we could call it that] started forming in the form of atomic nuclei at 3 minutes post BB, as temperatures and pressures kept dropping, enabling quarks to combine to form protons and neutrons. The first actual element needed another 383,000 years before H and He started to form when temperatures were such that electrons could combine.

 

Really river, get your nose out of nonsensical books pushing pseudoscience and paranormal and UFO's. Science explains most things without that rubbish...Some books you need to get.
The First Three Minutes: Stephen Weinburg. Black Holes and Time Warps: Kip Thorne.....Brief History of Time: Stephen Hawking...

 

What superforce ?

 

Stop trolling river, you have already been banned from the sciences.

 

What superforce ? ( from your post # 113 )

 

Thought that excellent WIKI link needs repeating, as river is playing games again and asking for what has been explained to him many times. Relevant issue under "Planck Epoch"
Thanks Write4U, though I know it won't make a bit of difference to the troll and his outlandish nonsense..

 

Are all other descriptions of relative occurrence also abstractions? Speed, mass, size, texture, frequency and temperature all exists as relational values that we recognized as real. If you conclude that reality can be defined by its relative sequential behavior, then time is real.

I’m saying that time is an inherent aspect of change, and if that aspect were not present, neither would change.

I would say human discovery rather than invention.

At the very least, being part of nature, if we know it, nature knows it. Don’t you consider it presumptuous to conclude how knowledge is perceived in the whole of reality?

Our recognition of the order of physical interaction doesn’t equate to the invention of it. Universal behavior still exists regardless of our perception of it.

How do these imagined calculations exist independent of the sequential reality that they’re proposed in? In order for change to occur, sequential states of existence must be part of the calculation, where each state is represented by periods or durations of existence. You cant have change without a component of duration.

The task of changing a tire has relational value to all other existential action occurring with it. It matters not if those actual relational values are formally recognized by us or not.

While our particular universe may have had a beginning, why presume the same for existence in general? If existence has no beginning or end, then neither does time and space.

The mathematical symbols used represent sequential periodic states, which definitionally imply elements of time.

Action doesn’t preceed duration, it always denotes its presence. If action is present, so is time. The characteristics of any associated duration exist regardless of their interpretation by humans.

Disagree , to your first statement .

All exist physically , independent of time .

Time is dependent of the above in order to exist . Inotherwords , not including time does not take away their real physical existence and actions .
