What exactly is the space time continuum.(yes that is how u spell it).
eyedea, would you be kind enough to give people a hint of what your subject is in the thread description? That’s twice you’ve stsrted a thread giving no clue to your question. This annoys most people, and if you keep doing, no one will respond. I’m giving you some good advice here.
In reference to your question here is a link for you which will explain far better than I can:
Here, let me see if I can help. It is best to have the subject reflect the question in some way.
“Continuum” just means that there’s no smallest unit of space and/or time. We’re not certain that that’s true, but we call it a continuum anyway, because most folks aren’t sure what to call a four-dimensional space. “Space-time” means that it encompasses space and time. In other words, if you name any location and any time, the point you describe is part of the space-time continuum.
Those are the definitions of the components of that phrase, but as Slip Mahoney’s link suggests, their sum is more than their parts. Time and space blend into each other in a way unimagined before the advent of special relativity. Slip’s link points out that by adding a square root of negative one to the time component, we can treat the space-time continuum as a four-dimensional euclidean continuum, mathematically.
(I prefer another approach. dx^2+dy^2+dz^2-c^2dt^2=0 is the usual description of the null geodesic, but that’s equivalent to dx^2+dy^2+dz^2=c^2dt^2. There we have space equals time, which seems incomprehensible since one side is three-dimensional and the other one dimensional, but it’s just a short step to adding a couple time dimensions: dx^2+dy^2+dz^2=c^2(dt^2+d0^2+dm^2). What that would mean, I have little idea.)
