Not if we had an infinite number of scientists!That's purely speculation, isn't it? We can't test that scientifically, correct, because we would need an infinite amount of time to test an infinitely large area?
Anyway. It's based on mathematical limits as they apply to probability. If something has a finite chance of success, the more trials you have, the higher the probability that at least one of them is a success. In other words, if the probability of success is finite, as the number of trials approaches infinity, the likelihood of having at least one success approaches one. In the limiting case, when you actually have an infinite number of trials, the likelihood of having at least one success is one (certain).
