Re: space and time
Time is a concept of measurement man invented to desiginate the length of duration/existense of that function

No, the intervals or increments of time is manmade for our benefit, but time itself is a physical property of the universe. Time and space are conjoined as twins and are homologous with one another.

In other words, you can't have space without time or time without space. That's why physicists refer to it as "spacetime."

Re: space and time
Why can't you have space without time?

The answer is Einstein's theory of Special Relativity. Time and space are relative to the motion of an observer and are not independent of each other. Space and time are connected to make four-dimensional spacetime. Think of it this way, when viewing 2-dimensional objects, they are flat. 3-dimensional objects, however, have depth and length. Time is it's own dimension. The 4th is all of them combined. But why?

Distance x's time = speed. Speed x's time = distance. Time divided by distance = speed. One is useless without the other as we define distances by time. It is a necessary prerequisite. The time it takes light to travel between two points. For example, one light year is the distance light will travel in a year. You just cannot have one without the other.

It's the same principle of how matter cannot exist independent of space. Where would you place the mass if mass displaces space or is within space? Same concept.

All you have to have for space to exist is existence.

Define "existence" apart from time, space, and matter, the three physical properties of the universe.

Now if events take place in that existence in space humans need some way of measuring the existence between events. Thus mankind invented the concept of time then came up with numbers to desiginate such interval's.

The intervals are mathematically devised for man's purposes, but time travels on regardless.

Re: space and time
Existence exists whether there is an observer or not. Things will continue to change without anybody to mark time.

Let me clarify what I mean.

The universe is expanding at a finite rate. That means from the finite point where time began, which is at singularity (t=0), that is when space also began. If space and time began at the same moment, and light travels at a finite speed, then quite literally as you take a snapshot in to space, you are in essence traveling back in time. Not to say that we are traveling back in time, but we are viewing an image that happened in the distant past.

I'm sure you are away that because light travels in a vacuum at a measurable and constant rate, that with the simple mathematics theorem of distance x speed = time. We then can now how long it will take for us to see an image in the present.

When we look at the Sun what we are actually seeing is an image of what occurred about 6 minutes in the past, because that's how far away it is. It's like a shockwave from a bomb. You see the image of the blast before the shockwave actually hits you.

*sigh*

This is really difficult to explain and I feel like I'm not explaining it well. Here, I suggest you watch the whole thing. It is quite remarkable and they explain it a whole lot better.
