I agree with your premise and conclusions… but I disagree that the head of the hammer ever “meets” a skull- the matter is “infinitesimally” small compared to the space between the subatomic particles that constitute it. What we sense is the energy release from the interaction of matter through the 4 fundamental forces of nature more-so than the collision of actual matter.I was only making a case that the universe could not be past eternal and that the concept of infinity doesn’t apply to our reality for the very reasons you illustrate. I can take an infinite set of negative numbers and add them to an infinite set of all the positive numbers and still get the same result if I then subtracted the infinite set of all negative numbers from all the positive.
However, there is nothing probable about the distance travelled by the head of a hammer that meets your skull and makes a loud thud with all due respect to physicists and engineers with their fuzzy quantum probabilities.
Also, your example of infinite sets might be mis-stated. I think you mean to ADD the negative set to the positive, not subtract the negative set from the positive set. Subtracting the infinite set of negative integers from the infinite set of positive integers will give a new infinite set of positive even numbers.
