This makes me happy. Some gravitational lensing.
So the layers are super-hexagon?
That hexagon might be famous but it’s news to me. Is that real? It’s amazing.
It will be fascinating to see whether the hexagon holds only one unit or an entire stack.
I’d love for that to be true.
It might be expensive to travel there, in which case only the very rich would be able to do so.
Or maybe the parallel universe could be used as a penal colony like Australia.
Or maybe we could use it as a dumping ground for our industrial waste.
We all know what’s there:
So there’s a parallel Earth right over there, and no one has plundered its natural resources? Be right back, just gonna start a transdimensional mining company.
If it IS inhabited, maybe the natives can be induced to help us develop their lands.
There was a sci-fi book? short story? that used this as a premise. I’m thinking it was Philip K. Dick.
Anyway, plot was that we figure out how to go to parallel realities. Since they’re infinite they effectively allow time travel. There are green cards, which allow inhabitants of the alternate realities to travel to the “prime” dimension. Grey cards allow inhabitants to go between the exploited worlds.
Image that sticks with me is the lead character having an affair with Marie Antoinette - him for the bragging rights and her for a travel card.
There is also the Long Earth series by Terry Pratchett and Stephen Baxter, where parallel Earths are strung together in a one-dimensional chain, with the nearest ‘links’ being the most similar to our Earth, and the most distant ‘links’ the most different.
I lost interest in book #1 about halfway through. It’s kind of boring and bland.
Ha, I thought it was an excellent series, up until book three or four where they build up for 4/5th of the book and rush to the end in the last bits. Then again, the idea of a whole load of untouched, silent Earths that can be visited at will is extremely appealing to me…

I’ve been a fan of the multiverse theory since I read about it in a Moorcock novel. This makes me happy.
That article is confusing because what exactly parallel or multiverses mean in practice seems to have wildly different interpretations. This seems to be saying that they interpret results backwards in time which somehow is being caused by interactions with another universe. From what I understand (which is not great) most multiverse theories are about non-interacting universes.
If there are an infinite number of parallel universes then one of them must be exactly the same as ours, but 100 years behind us.
That’s… not the problem though. It’s that generally these universes were thought to be unconnected.
In other words if you are getting communication with one parallel universe, and then say there are initiate
parallel universes… you pretty much lose causation in your universe, because you’re going to have infinite communications with those infinite universes.
Once you start evoking infinities, remember, any non zero probability thing is an infinite thing. Why would one particular parallel universe in an unified series of possible universes just happen to have the ability to communicate with our own?
That article and the one it references didn’t seem to cover this all very well.
I’d lean towards this one:
What this boils down to is simple: There’s so much we don’t know about neutrinos that astrophysicists and scientists are still trying to unravel. “We are **absolutely sure** that there is new physics out there to be found,” says Clancy James, a radio astronomer at Curtin University in Australia.
Jumping straight to “parallel universes” is a little over-the-top, and there are less mind-boggling theories that could explain what ANITA has detected. “There are a number of potential candidate particles that could account for the results from ANITA,” says Geraint Lewis, an astrophysicist at the University of Sydney.
Also, there are a lot of different kinds of multiverse and parallel universe ideas out there. None of them have a bit of solid evidence for them.
The one talked about most commonly by physicists these days is the idea of an inflationary multiverse where they happened before the big bang and are unconnected to our universe and kind of exist in an adjacent space/time (or have other physics entirely.) That doesn’t sound to me at all like what these articles are proposing with their overlaid parallel and reverse universe.

Yeah… well. That would be hard to get, no?
