I asked ChatGPT what would happen. Here you go:
If every atom in the universe suddenly gained one extra electron, the result would be instant, universe-ending chaos — in less than a nanosecond. Here’s why:
⸻
1. Universal Negative Charge Imbalance
Right now, matter is electrically neutral — the positive charges in nuclei balance the negative charges of electrons. Adding one electron to every atom makes every single atom negatively charged. The universe instantly becomes dominated by repulsive electrostatic forces.
Coulomb’s law tells us electric forces are ~10³⁶ times stronger than gravity. That means: • Atoms would violently repel each other. • Molecules couldn’t hold together. • Planets, stars, and galaxies — all held together by gravity — would be ripped apart by overwhelming electrostatic repulsion.
Within moments, all normal matter disintegrates into a plasma of electrons and nuclei being hurled away from each other.

2. Collapse of Atomic and Molecular Structure
Each atom now has one more electron than its nucleus can bind: • The extra electron would either occupy a weakly bound outer orbital or be completely unbound. • Chemical bonds depend on balanced electron sharing — those would fail instantly. • Solids, liquids, and gases all cease to exist in recognizable form.
Essentially, chemistry ends. There’s no more “matter” in the familiar sense — just a roiling cloud of charged particles.
⸻
3. Energy Release on an Unimaginable Scale
The addition of an electron to every atom requires — or releases — colossal energy, depending on the element and context: • Ionization energies and electron affinities differ between atoms. • You’re effectively forcing a global-scale electron capture reaction.
But the real kicker is that the sudden Coulomb repulsion between everything would dwarf any nuclear explosion imaginable. The entire universe’s matter would “explode” outward — far beyond the speed of galactic escape velocities — powered by the electrostatic potential energy now released.
⸻
4. No Stable Matter, No Light, No Universe
With matter annihilated into a universal electron-ion plasma: • Photons would scatter off free charges (via Thomson scattering). • The universe would become completely opaque. • Eventually, as it expands and cools, you might end up with diffuse clouds of charged particles, but never stable atoms again.
You’d basically reset the universe to something like an ultra-energetic pre-recombination plasma — except with the wrong charge balance and no chance of re-neutralizing.
⸻
In short:
Adding one extra electron to every atom would: • Destroy all atomic and molecular structure. • Overwhelm gravity entirely. • Convert the universe into a high-energy, negatively charged plasma. • Likely erase all physical structures — stars, planets, life, everything — in an instant.
It’s not a slow catastrophe; it’s an immediate, total one.
