Multiverse. There is a lot of talk about it again after the release of the new trailer for Spiderman No Way Home.

 

Obviously the favorite Spiderman survey starts:

Tobey Maguire

Andrew Garfield

or Tom Holland?

Let’s hope it doesn’t end up in a mess like Dark

The term was first used by William James in 1895 but did not refer to other possible universes:
visible nature is all plasticity and indifference, a multiverse, as one might called it, and not a universe.

Nature therefore.

Alternative worlds are rather present in the fiction of Jorge Luis Borges and H. G. Wells which I have already talked about.

The authorship of the thought on “parallel dimensions,” or universes coexisting and separated in space-time terms is instead attributed to Hugh Everett III controversial character who, however, did not have much consideration.

Subsequently the concept evolved into the so-called string theory: a sort of fusion between quantum mechanics and Albert Einstein’s theory of relativity.

The definition of “strings” derives from the idea of strings which, subjected to particular vibrations corresponding to particles with defined properties such as mass and charge, give rise to matter and energy.

Just like it was music.

Isn’t it fascinating?

Going back to conception in this case is a little more … swinging … but the contribution of Gabriele Veneziano is undoubted. 

From strings to get to the multiverse we need to consider Alan Guth’s theory of inflation and Andrei Linde’s new inflation not to be confused with the inflation that hinders us every day in this precise dimension.

Since the only thing clear in my mind is the chaos theory, I really like this video that shows the humanity of these unattainable minds and reminds us that the results can come even after “30 years” but that we must not give up.

Other times, however, the wait goes further, as in the case of A smooth exit from eternal inflation written in collaboration with Thomas Hertog but published after the death of Stephen Hawking, which Nick had mentioned in this interesting comment  about Schrödinger’s Cat

In another dimension… who knows, maybe we can imagine it like this

And you?
How do you imagine any other dimensions?

Do you ever think you have a Doppelgänger i.e. a person who has had exactly the same life experiences as you, but perhaps at this very moment he makes a decision that you would not choose?
