Time

[29apples]

If God created everything, then He created time.

If God was going to create time, how would he know when to start His creation when time doesn't exist yet?

Well, there wouldn't be a when.

 

[Strathos]

Perhaps He still is, has always been, and always will be creating time.

Without space there cannot be time and vice versa.

 

[Lost Angel]

Without space there cannot be time and vice versa.

This a idea of which I have trouble wrapping my head around.

Perhaps there has always been time and space in other dimensions.

There is no way a 3 dimensional being can envision the 4th dimension. We can feel its effects but nothing more. The only way we can see the 4th dimension is in mathematical models.

Imagine you are a 2 dimensional being where the only thing you see are lines in front of you. Now if I were to lift you (3rd dimension (height)) and you were facing a 3 dimensional object, you will still only see straight lines (sections of the 3 dimensional object) as you being a 2 dimensional being cannot see neither below nor above. You will however see a change in the lines as you move ever higher. you will feel the difference but you will never be able to see the whole 3 dimensional object.

Now move this to 3 dimensional object as regard to the 4th dimension. We can feel the effects of time and we move through space time but we cannot see time.

I read Flatlands and I always thought, "This whole story includes the 4th dimension!"

So does your example.

The analogy is kind of nice, but the analogy necessarily involves time as well. There's no good 2D-to-3D analogy for time because any example of it involves time itself.

Is time actually a dimension? Or is it just convenient to call it a dimension mathematically?

Time is change in the spacetime continuum. To be honest, it all depends on whom you ask and for what purpose. May I suggest you ask this question at Physics Help and Math Help - Physics Forums or PhysForum Science, Physics and Technology Discussion Forums (Powered by Invision Power Board)
