Yes. |
That would be impossible.
No point in the universe is infinitely far away from another point.
For the universe to be infinite, this would actually have to be true. There MUST be at least one point that is infinitely far away from another point. Let's assume there is such a point. We'll call this point A. Point B is touching point A and is in between point A and the point that is infinitely far away from point A, point C. Point B must also be infinitely far way from point C.. else.. we have just defined infinity as a number. Obviously that's nonsense. So, point B is also infinitely far away from point C. Now, there is the MidPoint. This point is between point A and point C. It also must be infinitely far away from point C, else, infinity would be defined by the distance between point C and A multiplied by 2.. which is nonsense. Thus, ANY point in a system in an infinite universe would be infinitely far away from every single point. Nonsense. Please note that when we speak of an infinite universe, it is entirely different from infinity in closed spaces (for instance.. there are an infinite number of numbers between 1 and 2). The difference is that in the math realm, numbers can be generated as needed to produced any number of numbers between 1 and 2. An infinite universe demands an external infinity that is
already generated.. which is also impossible.
