In science we attempt to classify everything. And everything seems to be a subset of something else. Planet is a part of a solar system, solar system is a part of a galaxy, galaxy is part of the universe, universe is a part of our dimension, etc.
Obviously there are exceptions to this, rogue planets, but we still consider them contained.
I understand the idea of multidimensions is theoretical, but if they exist, do we have a name or even a theory what might contain them?
Well my understanding was that according to string theory, we’re existing in one of many different dimensions that all kind of mirror each other.
As someone pointed out earlier, I’m not talking like 2D vs 3D vs 4D. But actually mirrored realities.
@ozoned I see, but if you call a “reality” a dimension, what is it that you call a universe?
