I know that sounds strange and I see what you are saying... but simple space is surely what we seek to measure with the concept of space time..space is space and space time is a human method of enabling humans to quantify it.

great topic...beats studying for an exam!
are you saying that 'space time' is just a mathematical construct to help understand the universe, whereas 'space' is a an intrinsic property of the universe?
i thought that 'space time' was an intrinsic property, as well, but it was not until the 20th century that we had the mathematics to understand it.
Steven's analogy is what I have read and never fully grasped but that is, i think, because my everyday experience does not lend itself to understanding 'space time'. Unless you know/understand the maths I think that 3D analogies are as good as it gets.
Perhaps if we were some sort of four (or higher)-dimensional beings we could see 'space time' like the three dimensional nose on my face.
