Can you store a full ME Storage Cell inside another ME Storage Cell?
If so doesn't that mean that you can nest them infinitely, thus technically making it possible to fit an entire minecraft world, no matter how large and how many blocks it is made of, inside a single ME Storage Cell that you can carry around on your hot bar?
Also, if you can nest them do they actually stack, or do the stay separate?
If they do stack does that harm the data contained in them in any way?
For whichever of the above is true, if you actually did mine the entire world and put it in nested cells and you decided to take a piece of cobblestone out, how many layers deep of 64k storage cells would you have to go through before you got to a storage cell that didn't just contain more storage cells?
Well, the surface of the overworld in minecraft is 60 million square meters (that's 3.6*10^14 blocks per layer), so if you assume an average block height of ~50 (it will be less than y=60 because of caves and bodies of water) and you're up to 1.8*10^16 blocks - that's 18 quadrillion blocks. 1 64k storage can hold a max of 8,128 stacks of items (520,192 items). So at maximum density it would take 34,602,608,268 cells to store all the items.
It would then take 66,519 cells to store all of those cells (assuming they all count as 1 type and stack). That last round of cells could then be stored in a single cell. All told that's 34,602,674,788 cells with items only down 3 levels of storage.
Now, I don't think cells stack and wouldn't count as the same type either, so you'd more likely be limited to 63 cells per storage cell, making that number bigger. You'd need a total of 35,160,714,856 cells with items nested in 7 layers of storage. That's actually only a difference of ~1/2 a billion cells.
