I remember reading that story :)
And once the purple (I seem to recall) aliens found one "earth" they were able
to dial back to the main earth from the suburb earth dimension they had
stumbled upon in their universe.

Asimov reckoned that "homeworld travel" would eventually lead to the discovery
of a version of the homeworld that had been invaded by aliens who had gone to
the trouble of inventing interstellar travel...
I forget the name of the story.

Remember the 90's US scifi series, called Sliders? Like that. Otherwise, we're
dealing with conjecture. Or the teapot circling Jupiter, which we can do today,
if we spent the money. Maybe Fermi's Great Silence is because its easier to
trade with different versions of one's homeworld, then put the time and energy
into interstellar travel, or they achieve world-line travel and destroy
themselves with conflicts, interworld-world.

If we can't interact with world 2, then its as if it doesn't exist.
Then it would not interfere. It is the whole point of the quantum: the
different terms of the waves can interfere, so we can't make them disappear,
even if we can't have branch-branch interaction: se still have the
branch-branch interferences.

Just as if there was a super civilization in the Sombrero Galaxy, but they can
never interact with us, nor we, with them. It resolves, from a human point of
view to Never-Never Land. On the other hand if we somehow can do FTL travel or
communication, or build Hyper-Tesla magnets and thus open up worldline
commerce, then its a mathematical hack used by physicists to amaze family and
friends! -----Original Message-----

The MWI can also be viewed as not positing that any new worlds are created,
but that the multiverse is a continuum that can differentiate between
previously identical worlds, and can continue to do this forever, that being a
property of a continuum.
How does Wiseman (appropriate name!) distinguish their theory from the MWI
experimentally.
(PS Apologies I don't have time to read the paper at the moment.)

Interesting speculative physics… that makes claims that parallel worlds may
be testable. “A new theory, proposed by Howard Wiseman, Director of the
Centre of Quantum Dynamics at Griffith University, is different. No new
universes are ever created. Instead many worlds have existed, side-by-side,
since the beginning of time. “ Regarding the interference patterns detected
by the single electron double slit experiment (first performed in 1974 at
University of Bologna) According to Wiseman and his team this interaction
between parallel worlds leads to just the type of interference patterns
observed – implying electrons are not waves after all. They have supported
their theory by running computer simulations of the two-slit experiment using
up to 41 interacting worlds. “It certainly captured the essential features of
peaks and troughs in the right places,” says Wiseman.
