Original: "Tachyonic gravitational dark matter production after inflation"
A sharp change in curvature after inflation could have created all the dark matter in the universe.

After the Big Bang, space curved so sharply that it 'shook out' dark matter from the vacuum. Simulations show that this mechanism yields exactly the amount of invisible substance astronomers see.
🎯 In quantum field theory, 'tachyonic instability' does not imply faster-than-light motion — it's just a sign that the system has gone out of equilibrium and is ready for a dramatic restructuring.
