Can matter be created or destroyed? Well, of course it can’t. It’s one of the fundamental laws of science.
But in the Bionicle universe, where real-world science seldom seems to apply? Absolutely. We see Toa creating their elements from nothing. Fire, earth, soundwaves, light…all of them can be summoned pretty much anywhere-even fire underwater, as confirmed by Greg.
However, I was thinking about it recently, and I realized maybe the Toa aren’t actually creating their elements from nothing.
All matter, whether it’s solid, liquid, or gas, is made up of atoms, which in turn are made of protons, neutrons, and electrons. Each element on the periodic table has an “atomic number” that designates how many protons make up an atom of that element. Example: Hydrogen atoms only have one proton. However, if another proton is added to that atom, then it’ll become a Helium atom. And so on and so forth. Neutrons and electrons also help to stabilize the atom.
And it’s not just protons, neutrons, and electrons, either. In some cases, atoms of different elements can be joined together to create another substance (two hydrogens+one oxygen=a water molecule).
So what I’m proposing for Bionicle is the possibility that, when a Toa seemingly creates water, earth, or some other matter-based element from nothing, they’re actually manipulating the particles in the air to form whatever element they’re trying to make. A Toa of water is in a dry desert with no sources of water? No problem! Just will a blob of water to form in front of you, and your magic elemental abilities will bring together all the protons and electrons you need to create that blob of water.
There are a couple other points to back up this theory. One point is that Toa can already manipulate existing elements (e. g. when underground, Onua can manipulate the earth around him). Another one is that there are some points in the story where Toa of ice create ice by freezing water. That is, they manipulated the water’s molecules/atoms to transfer it from a liquid state to a solid one. Therefore, it stands to reason that these Toa aren’t creating their elements from nothing: they’re just manipulating atoms to their will.
“Well, by that logic, then a Toa of Earth could just magically turn a block of ice into a pile of dirt!”
Actually…no. A Toa’s elemental power extends to creating their own element, not tampering with another one. Ice and water are a special case, since they’re technically the same thing but in different states. And earth and stone…well, good luck settling that 20-year-old debate.
