I've just finished watching Stranger Things Season 5 Volume 2, and let me tell you, my brain needed a big break after processing all that science. The recent episodes did not just entertain us with the monsters of Upside Down and drama. They actually explain the science behind all the chaos in ways that made me feel I need to rewire my knowledge of physics.

I found myself rewinding sequences several times just to comprehend what Dustin was explaining about exotic matter and wormholes. Stranger Things season 5 volume 2 presents a wealth of technical information, particularly in episodes five and seven. However, after watching everything and taking notes, I have finally grasped the science.

The story of the mysterious wall in Stranger Things

season 5 volume 2?

When I first saw the circular wall in the former episodes of Stranger Things Season 5 Volume 2, I assumed Vecna had built some out-of-this-world barrier. Dustin also stays on the same page initially, thinking the same thing.

He comes with a theory that Vecna's supernatural energy shield was created through dark magic and was used to protect himself and keep everyone from reaching Holly. Dustin, Steve, Jonathan, and Nancy head to Hawkins Lab in the Upside Down, believing they have found a shield generator there that they could destroy.

But the plot twist left me speechless. Dustin discovers his theory was wrong after finding one of Dr. Brenner's old journals. The wall was not made by Vecna at all. I learned, along with the characters, that science created this barrier, not supernatural forces.

The wall is actually the exterior boundary of a wormhole that connects Hawkins to another dimension. What exists beyond the wall? Nothing but the end of the world, according to Dustin. This revelation changed everything I thought I understood about the Upside Down.

As I watched Jonathan and Nancy investigate the area, they found what appeared to be a shield generator on the Hawkins Lab roof. When Jonathan threw a broken pipe piece at the mysterious hovering sphere, blue electrified clouds flashed across the sky. My first thought matched theirs. This was like some Vecna's dark powers. But here we are, wrong again.

Dustin explains to Steve that this glowing orb is actually exotic matter, and I had to pause the show to fully grasp this concept. From what I understood, regular matter is everything around us in three forms: liquid, solid, and gas.

Exotic matter is entirely different because it does not follow the everyday physical norms we are used to. Scientists in real life have theorized about exotic matter for years, believing it's the key ingredient needed to create and maintain a wormhole. In Stranger Things season 5 Volume 2, this exotic matter serves as the single energy source holding the whole wall and bridge together. Without it, everything would fall apart.


How the Upside Down actually works in Stranger Things season 5 Volume 2

This part completely changed my perception of the show's central plot. The Upside Down is not another dimension as I'd believed for five seasons. It's actually a bridge, more specifically, a wormhole connecting two different worlds. On one end sits Hawkins, Indiana. On the other end is what Dustin names The Abyss, the original centre of the Mind Flayer, Demogorgons, and all those scary monsters we have seen in Stranger Things Season 5 Volume 2.

I learned that this interdimensional bridge formed when Dr.Brenner forced Eleven to make contact with Henry in the other realm. The moment the contact was made, the wormhole ripped through time and space, creating the bridge. This unstable connection is what allowed Henry and his monsters to cross over into Hawkins through the Upside Down all along.

What fascinated me the most was understanding why the Upside Down mirrors Hawkins so accurately. Since the bridge formed inside Hawkins Lab, it created this mirror effect, blending both worlds. That's why Hawkins' architecture was enveloped with vines, Demogorgons, and other terrifying elements from The Abyss bleeding through.

After comprehending all this science, I finally grasped Dustin's plan for bringing everything to an end. The exotic matter is wildly unstable, just like the bridge it supports. If the team can successfully drop a bomb near the exotic matter, the entire bridge will fall apart. This would permanently sever the connection between Hawkins and The Abyss.

Once the bridge is finished, the Upside Down in Stranger Things season 5 volume 2 will cease to exist altogether. No more rifts between the different worlds. No more monsters crossing over, and the two realms would separate for eternity, finally giving Hawkins the peace it desperately needs.


Stranger Things season 5 volume 2 does an excellent job of blending complex science with an emotional narrative, giving us the answers we have waited years to receive while preparing for the epic finale.
