- Is it more likely to be a line going in one direction for ever, such as time can it progress endlessly, space.
- Or is it a circle time strarts progresses and at a point starts from the beginning again. (why do I think it could be a circle: Maybe the universe has a big bang, then the universe is expanding then gravitaion pulls it back to a single point and the next big bang takes place and that forever. This seems to be a circle. Also in respect to time. Time is dependent on matter, speed, space. Matter, speed and space if a big bang starts again are pretty much the same again creating the same time again. So maybe time progresses then starts again at the same point it has been previously).
Would like to have some thoughts on this.
Think of the difference between a line and a line segment. A line segment is defined by {2x+1 ; 0<x<5} while a line is simply defined {2x+1 ; x>0} these mathematical expressions are accurate definitions of what a finite segment is, and an line toward positive infinity, and can be negative infinity as well if it is defined {2x+1 : x<0}.
I can't think any other way to express infinity, it seems to be just a function where every input has a possible output.
In terms of space time, infinity would hold true that every point in the space time continuum has an equal number of points in an infinite series. Bear in mind infinity is interesting, but defined in theoretical terms.
