Ex nihilo nihil fit. This is latin for “out of nothing nothing becomes”.
Philosophically, nothing is truly the absence of any material at all, visible or otherwise.
The pre-Socratic greek philosopher Parmenides was the first to think of the “Ex nihilo nihil fit” theory, which states that, seeing as something does exist now, there can never have been a time when nothing did exist. Therefore, it’s only logic that there is something which has always existed since the beginning of eternity (if one can speak of a beginning when talking about eternity). The main question this theory makes us ask ourselves is, what is it that has always existed?
This theory has been recently opposed by modern theories, notably a certain theory which states that, seeing as physicists have calculated that the universe is probably flat, there are chances that the universe did spring from nothing.
However, in science, “nothing” as it is defined in philosophy, does not exist. There can only be vacuums, and even the most perfect vacuum is “filled by a roiling cloud of particles and antiparticles, which flare into existence and almost instantaneously fade back into nothingness.” .
Moving on, seeing as we can prove, by calculations which I can’t be asked to explain here, that the universe is flat, this sets out the conditions needed for the universe to spring from a vacuum, and to make the energy needed to create everything. Indeed, in a flat universe, gravity and matter can balance each other out, pretty much like an old fashioned scale.
So the antique theory that “out of nothing nothing becomes”, has been basically disproved by modern theories, at least concerning the origins of our universe. Yet it hasn’t completely been disproved, as we realise that the scientific definition of nothing isn’t quite the same as the philosophical definition of nothing. So, though a universe can apparently be created from a vacuum composed of swirling particles and antiparticles, which, granted, is not much, it can not be created by “nothing” in it’s purest sense.
But these explanations about the creation of our universe only seem to push the problem further back. Our universe, and probably countless others, were created by vacuums, but how were these vacuums created? When did there start being the particles and antiparticles which composed them? We can dismiss this question by the answer of “eternity” which then puts nothing at the beginning of the universe, seeing as, technically, eternity has no beginning.
Or, otherwise, we could simply imagine our own crazy theories regarding the universe, seeing as, overall, what difference does it make if our universe came from a vacuum composed of swirling particles, or from a desperate fight between two cosmo-pandas?
