Is quantum entanglement a manifestation of a fourth spatial dimension?

From basketball to quantum entanglement

The way to an NBA championship ring is long and tortuous, and I occasionally get bored with the topic of basketball. For that reason, I sometimes speak about topics that are not related to this sport. On this occasion, I am going to talk about the curious phenomenon that occurs, for example, when two particles such as a positron and an electron collide, creating two entangled photons.

They are like two associated elements: when one has a particular property, the other appears with the opposite property. For example, if one has spin up 👆, the other has spin down 👇, as happens with electrons. Spin is a property related to how a particle behaves in a magnetic field.

My hypercube interpretation

In the image above, we can see a representation of a hypercube: a cube with four dimensions. I have found that opposite faces, the ones at the extremes, are the same, even though they are far apart. So the two opposite red cubes, labelled 1 and 2, are the same. For example, if a person leaves the cube through side 1, it is as if that person were entering through side 2. An observer at 1 would say that the person is leaving the hypercube, but an observer at 2 would say that the person is entering it. The same happens with entangled particles: if one has spin up, the other has spin down. Why? Because they are the same particle, but in a fourth spatial dimension. When we see two entangled particles, they are really the same particle in another dimension.

In my opinion, this resolves the mystery of entangled particles and the “spooky action at a distance” that Einstein referred to.

Note: this is not a proven theory; these are conjectures.

Clarification added on 22 October 2026: numbered hypercube cells

The drawing below numbers the eight cubical cells represented in the original 2020 illustration. The central cell is 1 (hidden), its six neighbours are 2–7, and all six outer red cubes represent the same cell, 8. The red cubes labelled 1 and 2 in the original illustration are both labelled 8 in this numbered version.

Fermilab video: quantum entanglement

For more detailed information about quantum entanglement and the relationship between the spins of entangled particles, you can watch the following video from the Fermilab channel. It illustrates how the spins of entangled particles are related. The physicist in the video, Dr. Don Lincoln, defines quantum entanglement as “two subatomic particles that share the same wave function.”
