@mysterystar,
Is your argument:
1. Space and time are on a continuum, such that:
2. When you look into the distance, you see the past,
3. And therefore there is a missing quantity of mass?
That's not exactly a dialectic. It doesn't have an antithesis or the synthesis forming from it. A good example of a dialectic is:
1. Space and time are on a continuum, such that what appears to be the distance is in fact the past, and therefore there is missing mass. (thesis)
2. Space ... past, but there can be no missing mass. (antithesis)
3. What we perceive to be missing mass could be mass that we simply have yet to detect. (synthesis)
If I may note, mysterystar, your second premise is quite right. It takes time for light to bounce off a particular object and reach our eyes. In fact, what we perceive is what happened several milliseconds in the past. What we perceive the Sun to be doing
right now is what it was doing approximately eight minutes ago. The fact that light exhibits this behavior leads to the creation of what physicists call "light cones." Since we use light to detect stuff, whatever lies outside our light cone is inherently undetectable. Therefore, there is mass we cannot dectect, and we can perceive it as "missing mass." Thus, your argument, while poorly worded, seems to be quite right :bigsmile:.
