Reply to comment by Argonated in The multiverse by Manureofhistory

All possible universes if I remember correctly even in MWI? I claim no expertise but there are different kinds of multiverse theories. The cosmological inflationary and the MWI and branes (?) though some would like to link them? I’m not sure to what extent MWI is meant to be multiple versions of ‘this’ universe - the cat being alive in one and dead in another but the laws of physics still being the same? Or does it also produce universes with varied basic conditions? I don’t know - but i think the cosmological inflationary multiverse does include the possibility of universes with very different conditions and some parameters are unsustainable - the bubble pops , deflates etc.

It can indeed.

I keep trying to find something on any limits to the worlds of the many world interpretation but it’s difficult.

I’m curious as to under these circumstances what determines whether something is possible or not. And are there potential universes that don’t exist because they are not the possible outcomes of any quantum ‘measurement’? Does that make sense?

I did find this .. though obviously I have no idea as to the validity ..

The laws of physics are the same in the multiverse.
