does space and time have substance ?

can time change movement in and of its self of any object?

and does space have substance in the absence of plasma and/or matter ?

I say no to both questions

I don't think time has any effect in and of itself. Time is really just a measurement of change. Change is the real effect. Or time may be the effect of change.

Without plasma or matter ,it seems space would be void.

or precisely , the consequence of movement(s) of things and their interactions





exactly

I'm not sure if time is really a consequence, if thats what you mean.

okay

imagine time without any type of movement what-so-ever

now is that possible ?

There would then be no need for the measurement,time, but I'm havin trouble seeing it as a consequence. I would think that a consequence would need to be some sort of effect. I think change is more a consequence of movement.

change is a consequence of movement but so is time

time is just a MEASUREMENT of this change

I must agree, then ,that time as a measurement is a consequence of movement.

But only because we exist.

good you understand the reasoning



and before we existed then what ?

I am assuming change occured before we existed

but with no one to measure it's rate, I don't think time really exists without us.

of course



oh the rate of change always existed

its just that to the objects themselves , the mesaurement of the rate of change didn't matter as to why the change took place in the first place

I'd say that's pretty much the truth of it. I guess that's why change is said to be the only constant.

actually I perfer movement

Can the half life of an isotope be said to involve movement?

can time change movement in and of its self of any object?

and does space have substance in the absence of plasma and/or matter ?

I say no to both questions

The entire transition from Newtonian physics and classical mechanics to general relativity and quantum mechanics hinges on the realization that space and time are not independent realities.

My only additional suggestion is to consider the notion that reality is composed of events not matter;

and that space and time are merely aspects of the relationships between events.

matter is the essence of the events in the first place
take away matter , on what physical platform then does reality take place ?

My take on the original question is that time is a tool of measurement created by man... like looking at the position of the sun. Past and future only exist in our minds. The only time that actually exists is right now. Some events happened already, and there are more events yet to happen. The "past" is merely memories or evidence of events that have already happened. "Future" is merely a projection we have in our minds that we create from the information we have... known as the "past."

Motion is change. Pebbles in a river don't get smoothe because of some magical force called "time," it is the motion of the stone with the other stones. Our understanding of how it works lets us see the process, see the events that caused the result... they are smoothe.

I want to keep going but don't want to lose ppl by having a LONG post
