Magnets fall, malls rumble, and the Upside Down gets a power upgrade
The season opens in a secret lab of evil. Scientists are firing a massive laser at a concrete wall, trying to reopen the gate to the Upside Down. The laser sputters, sparks fly, and the test ends in failure.
This laser isn’t just for destruction, it’s a high-energy particle beam, likely inspired by real-world particle accelerators like the Large Hadron Collider (LHC). In theory, if you concentrate enough energy into a small space, you might create a spacetime anomaly: a wormhole or a quantum tunnel. The Russians are trying to brute-force a shortcut through dimensions, using energy to punch a hole in the fabric of reality.
And that kind of energy doesn’t go unnoticed. All over town, things start to glitch. Most memorably: the magnets. Fridge magnets fall off. Compasses spin. Joyce, ever the queen of noticing weird things, knows something’s off. This is a classic case of magnetic field disruption. In real life, magnets stick because of invisible fields: like tiny invisible hands holding on. But if a stronger force comes along, those hands let go. Magnets fall losing their magnetism.
Then there’s the shaking. When the machine powers up, the entire mall trembles. That’s not just for drama, it’s a physics concepts of resonance. Have you ever noticed that bridge shakes when heavy vehicle passes? That is resonance. In physics, resonance happens when something vibrates at just the right frequency to make another object vibrate too. It’s how a singer can shatter a wine glass with their voice. Or how a bridge can wobble if the wind hits it just right. In Hawkins, the machine’s energy is so intense, it’s making the very walls hum with tension.


Back in Hawkins, Dustin’s compass starts pointing the wrong way. He and the gang realize something is interfering with Earth’s magnetic field. It’s not just a glitch; it’s a clue about where this massive machine is.
Usually, compasses align with Earth’s magnetic field. But a strong enough electromagnetic field can distort local magnetism. This is similar to how solar flares from sun disrupt our satellites. The laser’s energy is warping the environment, hinting at a localized magnetic anomaly.
Season 3 is a story of weaponized curiosity. Much like how nuclear reactions studied out of curiosity is now weaponized.
Isn't Physics absolutely mind-boggling subject?
Keep an eye on next season explanation!
