playing with 4D coordinates

What else is there to plot?

nothing.

[swansont]

nothing.

Yes. What was the point of the question?

---------------------

In other words, we consider that at some definite time, spacetime is empty except for that we can observe.

There are things too far away to observe (not causally connected to us), but otherwise, yes.

Thank you.

And if (IF) they were objects that filled spacetime, instead of being empty, those objects would be unobservable.

Unless they are invisible, no.

I know it is hard to swallow.

 

Please take some time rethinking the picture.

 

I am at t=0 observing a universe that spread along the diagonal d=ct.

 

After 1 year i am at t=1 observing the same universe that spread along the diagonal d=ct

 

and so on at t=2 again the same universe collated upon d=ct

 

The observable objects of the observed universe travel through time on a parallel path to me. I observe constantly the same universe.

 

The superposition of all diagrams t=0, t=1, t=2 fill the entire spacetime diagram. Till here we must have an agreement.

 

But

 

At any time, between t=0 and t=1, what are we traveling into ?

_The answer is; we are traveling in spacetime. IOW we are traveling in a supposedly "empty" spacetime where there is "nothing' else than d=ct observable objects. (you seemed to agree on this)

 

Now, i am arguing that one can fill the whole diagram with 'other' objects that will follow a parallel path to us but with a gap in time. I am arguing that those "other" objects would be unobservable.

 

Even not from a picture from T=minus 1.

Because at T=minus1 we were observing objects on the d=ct diagonal.

 

I am offering you a new denser Universe.

What you are doing is equating an object's spacetime coordinates with its distance from you. They aren't the same thing.

Exactly. Object's spacetime coordinates should have nothing to do with mines. What (i am arguing) is happening is that I am scanning only the d=ct part of the universe. If the universe is traveling at the same pace that I do, I continuously scan the same objects.
