What's More WTF than Parallel Universes? Space and Time Are Not Real. | Big Think.

So one explanation that people have reported over the years for a spooky connections and for quantum mechanics actually in general is that it's an indication we live in a multiverse. In other words, that there are other domains of reality out there that we have only very dim glimpses of. Quantum mechanics says that when I measure a particle, I can get a random result and there's no explanation for that random result.

So if I flip a quantum coin, it comes out heads or tails, and I see heads. The strange thing is, the mathematics says I should see heads and tails. So it's always been a mystery of why I see one or the other. The proposition is that it actually does come up heads and tails; it becomes a place in our universe and tails in another universe.

So the idea of different universes, of parallel universes, is a way to make sense of the multiplicity of outcomes that are observed in quantum mechanics. People have proposed this would be a way to actually kind of get rid of the normal county that the number of county, the spooky action at a distance, is actually our kind of imperfect glimpse of a multiverse of parallel universes.

Individually, those universes all behave completely locally—no spooky action. I kind of actually have a lot of sympathy for that position; it's actually kind of awesome to think that there might be parallel universes not just out there, but actually in here. We could be kind of just cheek by jowl with parallel universes all the time, and we've never even sensed them.

Every measurement we make causes the universe to branch; Carolina persisted, speak conjured up all the time in this kind of amazing preconceptions of Major Arcana. Gone off the idea as much as I can be drawn to initially. The reason is that I think when you see these spooky actions in locality in a broader context, for instance, in the context of other places where they occur in nature—not just for the particles, but they also seem to occur for black holes.

They seem to happen in cosmology; they seem to happen in the workings of gravity. There's a variety of contexts in which you see spooky actions, and those other contexts are harder to explain in this kind of parallel universe scenario. But what they really seem to play into is that space and time are derivative.

The real message of the spooky action is that space and time are not fundamental. The particles are rooted in a deeper way where space and time don't yet exist, and that's the way to explain them. So the building blocks of the world may not be tiny things. What could these building blocks be? They're not tiny—that's kind of what we think of as a building block.

A Lego is smaller than the thing you build out of the Legos. They may be, in what seems to us, enormous things—things that span the entire universe or somehow act in concert with one another to produce these phenomena of space.
