Thus far I have absolutely no problem! As long as we are clear that that is the way in which “infinite” is being used, that’s fine. In thinking about infinity, that was the point at which I ran into complications.

Infinity is simple if you are looking at it from a great distance. It is easy to think that we can visualise time stretching to infinity in the past and future, or a void going to infinity in every direction. As long as you treat it as a “concept”, it’s simple.

This is where we seem to part company. I strongly suspect that there can never have been a time when there was absolutely nothing, or there would still be nothing now. If this is the case, something must be physically infinite. This leads to the question: What does it mean to be physically infinite?

There never was nothing.
