The Immediate Effects

A 20% increase in gravitational force would fundamentally reshape our universe. Stars would compress more tightly, increasing their core temperatures and fusion rates dramatically.

T + 0 (Instant)

All objects become 20% heavier. Humans struggle to stand. Buildings experience increased stress.

T + Hours

Atmospheric pressure increases. Weather patterns become violent.

T + Days

Tidal forces intensify. Coastlines flood. The Moon's orbit begins to decay.

T + Years

Stars burn through fuel 40% faster. Our Sun's lifespan drops by 2 billion years.

Why It (Barely) Survives

The universe's fundamental structure remains intact. Stars still form, planets still orbit, and life—though radically different—could still evolve.
