The Universe Is Made of Tiny Bubbles Containing Mini-Universes, Scientists Say

Thanks for the link

In Minecraft, the whole world is made of cubes. Things are either cubes, or in the empty space where a cube could be. This line of theories (there have been many over the years) argue a few things.

First, our reality might also be made of similar Minecraft 'blocks' and block shaped empty space (that 'space is discrete, not continuous').

Second, that what a block does in one block shaped empty space is not necessarily going to tell us what it will do when it is in a different block shaped empty space. (This another way of saying the universal constants may change at different points in a discrete spacetime, which is ANOTHER way of saying different 'universes' exist within these points.)

Third, that the blocks and block-shaped empty space inform each others border/shape/volume and relate to one another in some way. (All of this together creates a larger structure, which they call a foam).

I think that's the basic gist. A quantum particle is like a block moving positions in this 'Minecraft grid', and as it does this it becomes subject to different universal constants.
