 We are energy. Now, what's the difference between a dimension and a density? Okay, so this is really, it took me some time to wrap my head around it, but I definitely now understand it. So a dimension, it's also mathematics, is a certain, like we say, third to fourth dimension or fifth dimension. We hear that term. So a dimension is a space, a container, you could say, of which we can play in or we can see.
