What if you could step into a portal and emerge from the very same portal you entered? This isn't just a sci-fi daydream; it's a fascinating question that delves into the realm of theoretical physics and the nature of portals themselves. Let's explore the peculiar scenario of what happens when a portal passes through itself.
Imagine a simple 2D space, a line where portals behave just as they do in our 3D world. When an object enters a portal, it exits at the same position relative to the other portal. Now, consider placing two portals back to back. If you can't discern the presence of a portal, it suggests that the portals' behavior remains consistent, regardless of their orientation or movement.
But what if one portal starts to pass through the other? If the top of the blue portal enters the bottom of the orange portal, it logically should emerge from the bottom of the blue portal, maintaining its relative orientation. This visualization might seem bizarre, but it's the expected outcome based on the portals' design.
Now, the plot thickens. If we continue pushing the blue portal into the orange one, we'll encounter problems, much like trying to fit a square peg into a round hole. However, if we introduce a twist and place the blue portal's star end near the top, it exits closer to the top until it loops back into the orange portal near the circle end, emerging farther down. This creates a mesmerizing, almost recursive loop.
At this point, it might appear as though the circle end of the blue portal is vanishing into the orange one, but this is merely an illusion. When the orange portal is hidden, it becomes clear that the parts of the blue portal entering the orange one are still present, emerging from the star end and aligning with the orange portal's face.
Keeping track of this can be challenging, but numbering the blue portal can help us trace its segments. The key is that the entire blue portal must remain visible and in existence, even as it twists and turns in this recursive dance. This means that 100% of the blue portal must be accounted for, no matter how convoluted the scenario becomes.
The real conundrum arises when we consider the blue portal passing entirely through itself. For this to occur without the portal getting stuck or compressed, it would need to be infinitely thin—a mathematical impossibility for a rigid, non-infinitesimal structure. However, with a bit of flexibility, a 2D portal can pass through itself in various configurations, and the same concept applies, albeit with more complexity, in 3D space.
Surprisingly, it is possible to create a visual representation of a portal passing through itself, complete with a grid to confirm that it remains 100% outside even during this self-intersection. And if we want to observe this phenomenon through the portals, the result is a stunning display of visual trickery.
The journey through this theoretical exploration reveals that even in a universe of our own making, the unexpected can emerge, challenging our understanding of space and reality. The animations that bring this concept to life require not only visual effects software but also a fair amount of computer coding—a testament to the ubiquitous role of coding in modern creativity.
