Very good article! Thank you.
I am going to suggest something for you to learn, as it will change your perspective of reality in a scientific manner, which supports Plato's allegory. Learn about the "delayed choice double slit experiment."
It is a physics experiment that demonstrates the non-existence of space and time, or at least shows them to be fundamentally different than what we conventionally think of them to be.
I will try to explain it here (mainly as an academic exercise to myself)...
1) When you shine light, as a wave front, onto a barrier with two closely approximated slits, the light projected through those slits will hit the back wall (behind those slits) to create a pattern that is striped. The striped pattern is called an interference pattern, because it has several (more than two) light and dark alternating bands that coincide with the wave nature of the light causing constructive versus destructive interference. This can be illustrated and explained on a piece of paper using simple geometry. Easy peazy.
2) When you send a single photon, not a wave front, through those slits one at a time (let's say one every second) and you do this for a long time... and record the light hitting the back wall... you will still get the same interference pattern. So, at this point, you will agree that the interference pattern has nothing to do with the wave front geometry that initially explained the pattern. Somehow the photons are interfering with themselves, one at a time.
3) When you send a single photon, again not a wave front, through those slits one at a time, but now decide to place a sensor to detect which of the slits the photon has passed through... you no longer get an interference pattern. Instead, you get two stripes. One stripe for the left slit and one stripe for the right slit. So, observation or measurement, has unexpectedly changed the result.
YOU MIGHT THINK THIS IS PERHAPS THE SINGLE MOST IMPORTANT FINDING EVER, BUT IT GETS EVEN MORE MYSTERIOUS! (you can tell because of the capital letters and the exclamation mark. Lol)
4) BACKGROUND INFO: When you take a photon and split it in half, such that there are two new photons, those two photons will be entangled. Entangled particles exibit the behaviour that if you measure one of the particle's properties, it's entangled partner will have the opposite quality. For instance, if you measure one photon and determine that it has a vertical polarization, then it's partner will have a horizontal polarization.
5) Now, when you take a photon and split it in half and allow one of the halves to go through a double slit at a close distance, and allow it's partner to go through a double slit at much longer distance, something very strange happens. When you place a sensor at the very long distance double slit to detect which slit the photon went through, it will show you the expected absence of interference pattern... with only two stripes of light... one left and one right. When you don't do measurements with the slit sensor the pattern goes back to the expected inference pattern... with many bands of light. Good so far? The photon that travels to the short distance double slit will have already collided with the wall, before it's twin reaches the long distance double slit. So, if you measure the long distance photon, by slit detector, even though the event for the short distance photon is already over.... the short distance photon will behave according to the decision made to observe-or-not-observe made in it's future. Furthermore, if you create a random decision maker to observe-or-not-observe after the short photon's event is over but before the long photon's event, you will still get the same result. In other words, a decision made in the future alters the past. This has been experiemntally proven.
6) The other quality about entganglement is that it is instantaneous, and it does not matter how much intervening space there is between entangled particles... the comunication between them occurs instantaneously and even to back propogates in time.
7) CONCLUSION: time and space do not exist as we think they do.
With respect to the Plato's Cave Allegory, my point is this... if our minds are unable to grasp our true reality, then it doesn't matter where we go; we will always be in that cave. I think escape, therefore, must be an inward journey.
