I liked jpetruccelli's first definition. We are inside spacetime looking at it. To us mass 'is' and depending on what we deem this 'is' to be we will have our definition. To a goldfish view the 'distortion of sight' we know it to observe as it looks out the bowl into our living room is the 'truth'. And mathematically it is a truth as it will be a correct observation from it's point of view only needing some corrective definitions from our view to 'fit'. The problem is to know where those partial 'truths' ends. The question when narrowed down is the one of 'objectivity'. Is there a 'objective truth' explaining everything?
And that to me becomes a philosophical problem. Is there one 'truth' describing them all, or will there only be 'partial truths' that mixed together presents us with spacetime? String theory tries to build from a 'objective' 'whole' truth, if I get it right, with the addendum that I believe it to presume there to be one-dimensional strings already existing? Then we have other definitions too, like 'dimension less points' which seems almost mystical :)to their nature. The question might be if we see SpaceTime as something with a 'boundary' limiting it and if we then expect it to be something outside that 'boundary' defining it. Or, if we like I believe is only 'emerging' as restricted phenomena of a greater 'whole' in where we don't really exist. If that would be the case then SpaceTime will be our 'balloon' and the idea of inside/outside will lose its relevance. And then those 'dimension less points' are the reality.
We will narrow it down further, on that I'm sure. But if that will lead to us to a 'greater perspective' I don't know. We are very much 'goldfishes' too. Defining our world from what we can observe. But that is the way we have to go it seems to me. So MichaelS if you have another idea how we should make our observations feel free to present it/them. We've gone some way since we thought that it was the Gods deciding what our world should be, and we still have some way to go

...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!
