One of the most disastrous consequences of the actual infinity is the conception of space and time as a continuum infinitely divisible. Basic concepts of physics as motion or velocity were, and continue to be, founded on that assumption. Matter and energy were also initially conceived as a continuum infinitely divisible. But the obstinacy of facts finally revealed that rather than continue, they are discontinue (elementary particle and quanta, respectively). It is now being suggested from different areas of science that space and time could also be of a discrete and finite nature. If that...
