Once again, </thread>


I just did! Tell me where my mistake is in the diagram, and quit saying, "you can't do that." That is a 2 year old's response.

You don't need ANY objects to have distance. Distance is inevitable! There is no other alternative!

So if there was only one object - how big might it be?

If there were no objects - how wide would the universe be?


An object can be any size greater than zero.

If there were no objects in space it would simply be space, no objects. Space is inevitable, there is no other option! Don't you understand that? You don't need objects to have infinite space!

Objects reside in the infinite volume of space!

It is impossible to not have infinite 3 dimensional distance, I don't care what your Einstein link tells you.

Space is infinite volume, and volume is 3 dimensional distance.

From any point there is infinite distance in every direction from that point.

You are trying to say that you can do away with space. That is simply impossible! Massive objects can be created and destroyed, but infinite space is INEVITABLE!

Well, Motor Daddy, you are just wrong. Space is not nothing. It is the gravitational field of the universe. Absent matter and energy, there is no space and no time. And it is not possible to define a velocity in a universe containing only one object. Your whole thread is bollocks. So sorry! :D

Distance is nothing. 3 dimensional distance is volume, and space is INFINITE volume.

What you are saying is that there is no distance outside the universe, and that is absolutely wrong.

What do you think, that distance just stops? How would distance stop in any direction, a brick wall with a do not enter sign?

Oh, lord.

No, I did not say that space just stops. I said that space is the gravitational field of the universe. Without matter and energy there is no space or time. There is nothing at all (and space is not nothing).

You are calling the matter of the universe "space." That is not space, that is the object the universe. The universe is an object, like a ball, only larger. There are other "balls" in space besides our universe.

You live in an object called the universe. You also live in a galaxy. You also live in a solar system. You also live in the Earth. All of that lives in the multiverse, and all of the multiverses live in the "Googleverse." LOL

You get the point.

              You have been observed.
    Though often tempted to encourage a dog to distinguish color I refuse to argue with him about it
    It's just the same Satanism as always -
    • separate the bottom from the top,
    • the left from the right,
    • the light from the dark, and
    • blame each for the sins of the other
    • - until they beg you to take charge.
    • -- but "you" have been observed --

The real fairy tale is claiming the limits of our knowledge are the limits of existence. Typical egotistical mankind, the center of existence, and if it's unknown to him, then it doesn't exist. Laughable!

We live in a system so big it's beyond our abilities to observe. There are systems so small it's beyond our abilities to observe. To claim our capabilities are the limits of existence is absurd!

We know for a fact that:

We live in the Earth
We live in the solar system
We live in a galaxy
We live in a universe

...and that's the extent of our limited knowledge. To claim that's all there is because that's all we know is outrageous!

Right. It is only against an unarticulated background that representations can make sense to us.

What you see as a light sphere is seen by everyone else as a light ovoid if they measure you to be moving.

You will also find that a flash of light at the centre of your sphere hits the walls simultaneously but, owing to the relativity of simultaneity other observers will see the flash hitting the walls of the ovoid at different times.

Here is a good intro to SR: https://en.wikibooks.org/wiki/Special_Relativity
