PORTALS:
Portals are a very big staple in Minecraftia with good reasons why. Before technology that enabled travel between the three realms using an inter-void connection, portals were used to connect to the Nether, the End, and non-world based dimensions. It should be understood that the topic will revolve around the main portals: The Nether and the End.
The nether portal is a very easy portal to both create and use. While exact dates are unknown, Obsidian was used to create a portal shape and began to be used around the time of the 420 with the Zombus first using these portals to begin first contact with the Withus. Afterwards, the portal leaked about and other races began to use it, and even the Players began to use it during the 16th Century. Aside of those aspects, the portal became a very popular image used in the Minecraftia image.
What marks interest is how does 10 blocks of connected obsidian become a portal? Theories, in the older days, suggest that it was due to the depth of the Obsidian's formation that made its property work. However, once players began to create obsidian on the surface, then the theory was reworked to be a mix of an elemental power between air, water, fire, and diamond. Lighting the portal frame also was investigated as a connection was found in 1954, showing a sign that the portal entered a solid state that was also creating a plasma radiance, emitting two background radiation types which explain the purple color. In 2022, there was a further discovery that concluded that there were actually DR pulses that, not only created the connection from the Overworld to the Nether, but also synthesized a Nether Portal in the Nether.
Furthermore, from what has been discovered, the portal cannot transport, or even be activated, in the End for some unknown reason. Many suggested there is a double void interference while some suggested it's due to the irregular placement of the End that throws off whatever "DR-vortex" hypothetical idea that forms.
The End portal is obviously going to take all the excitement for just about everything. The portal isn't just a bizarre object itself, but the actual physics and laws of it shouldn't exist. Let's start with the beginning.
The End portal is made up of a five by five framed that only contains twelve actual frame pieces to activate it. In order to activate it, you need to insert however many eyes of ender are missing, since there have been reports of other End portal frames containing between none to five eyes. After inserting, the portal opens up and you go in, bringing you onto an obsidian platform and you continue your way until you jump back into the bedrock End portal to return to the world. There are, just from the following facts shown, that make no sense in terms of physics, theoretical sciences, and has even baffled MRF.
For starters, the frame in the stronghold is currently identified as endstone with several unknown materials included. The endstone is interlaced and even fused with this material, giving off some form of oxilate that no only powers the portal, but also is strong enough to withstand both voids and go through the Nether. The next strange thing is that when you peak into the portal, there is virtually no radiation, but what appears to be particles of many Endus colors. The problem with these is that they were shown before to actual move across, but now stay still. Other reports say they still move, which suggest they may be living organisms. There is no proof as to what the organisms, if that is what they are, are but there is enough evidence that they live in a void that is entirely different from the void we know.
Next part of the portal is how the portal also manages to spawn out an obsidian platform. Some have went as far as to say that there is a mystical property to the obsidian for the usage in portals. But there is no trace of obsidian in the End portal, but there is to the second portal stage.
The second stage is oddly the entire entrance island. A portal stands in the middle, made of bedrock, while there are several obsidian pillars with crystals at the tops of them. Then from these crystals is the long dead Ender dragon. Now, what must be understood is that according to the setup, the dragon may have been considered like a mega lock, or the first unbreakable lock. What sparked the interest is that why was all of this done? Reason, it was created so return would be virtually impossible or very hard. Now, due to the Pigus invasion in 984, you'd expect that the Pigus invaded the Overworld… well…
They didn't because they were frightened by the newly spawned portal and actually blocked it off and created something similar to the one in M. Saudi Arabia in Meccus. Back on track, according to MRF, the bedrock portal breaks already three laws of current Minecraftia physics. First is that it's bedrock and it doesn't even appear in the end. Two, the dragon's death was linked to the portal, meaning there was an activation linked to that dragon, which we cannot conclude because its death, and if you assemble the egg plus four crystals, you can bring it back to life, but the portal remains open and the dragon continues. Three, similar to the beginning portal, the void beings along with the Overworld-End travel exist and operates the same.
Other facts about the End portal include that it isn't connected directly, and requires another activation, aka the dragon's death; the time to go in and get out is virtually instant where as the Nether portal takes some time to do so; and lastly, there was an End portal found in the Nether that helped in the progress of the Pigus invasion, but it was destroyed in 1455 by an unknown explosion.
That sums up the chapter on the two portals, with the bizarre standards and unknown features and materials that make them up. The Nether portal is elementary while the End portal is as rigorous as imaginary numbers, or even more so. But nevertheless, both portals are necessary in the historical world and even in the modern world in order to get to the Nether and End.
