A simple analyzing for space-time

We can not perceive anything simultaneously. Because the velocity of light is a limited value; it is high, but it is limited. And the light needs time to travel distances.

Therefore we can not perceive the units of universe at real position simultaneously. Visible form of universe is deformed.

We can find the effective form of universe, if we know the absolute form.

We don't know the absolute form (isolated from the perceiving performance of observer) but we can guess some forms. For example we can examine according to the form like spherical surface in big bang theory.

The analyzing is very simple:

[xersan]

We never see the simultaneous situations of events and subjects.

If the real form of universe is a spherical surface we can see this form like asymmetric ellipsoidal because of limited speed of light.

---- Effective form of universe is like a drop (figure at left attachment)

All points on the drop form are determined by these relations (at right attachment)

F' : Observational position of the cosmic unit.

F: The position of the cosmic unit at present

Vg: The expanding velocity of universe at present.

Vg': The expanding velocity of universe at past.

[xersan]

We would have some possibilities when we found the effective form of universe. For example we can calculate the parameters for every age of universe and we can set diagrams due to this data. We have observational graphics/diagrams and we can compare the graphics.

If you are in two rooms of your house separated by doors, light is also limiting our ability to see both at the same time. This doesn't mean things can't occur at the same time. To prove this, If we had two cameras, one in each room, with the same lengths of wire, we can make a split screen to show what is occurring at the same time (timeline of the screen). We can then transmit an order and record it. If you try to use either room as the baseline reference it creates the impression there is no simultaneity.

One explanation for this affect, is we think in terms of space-time. If two things were occurring at the same time, but separated by space, we are not dealing with space-time, but just space, since time factors out. But if we still call it space-time, we are trying to approximate distance with distance- time. Based on this approximation it will appear like they can't synchronize. This observation could be used to prove space and time, although connected, are actually two separate variables that we merge into one and call it space-time.

For example, say we synchronize two clocks that are physically as close as possible so we can see both. We do the best we can and make a note if we are a tiny bit off. Next, we separate them. With all else being equal, we know they are still in synch, within our tolerance.. As distance increases to make it less obvious we ask another team, who doesn't know what we did, and ask them if they are in synch. They may say no, due to trying to define distance in terms of space-time.

The analogy is making a linear relationship look 2-D. Instead of just using the X-axis to define the line in one variable, we give it an "angle", so we can also use the y-axis. It will still be a line with the same length, but it now has a variation away from the scaling in the original X-axis.

Thanks for your interest and explanation.
