Friction in the Early Universe: Saving Inflation ⚡ экспресс
Original: "Reviving Motivated Inflationary Potentials with $$K$$-inflation in the light of ACT"
An unusual formula for the field's kinetic energy saved inflation theory after unexpected data from the ACT telescope.

The cosmic 'engine' of the early universe was sputtering—new data from the ACT telescope didn't fit the theory. Physicists found a way to add 'friction' that fixed everything. Now this engine promises to generate a hum of gravitational waves, which future detectors will catch. Perhaps we'll hear the echo of spacetime's very birth.
🎯 Before it was 380,000 years old, the universe was as opaque as thick fog. The light we see in the cosmic microwave background images is its first 'photo', taken when the fog cleared.
🎬 What if, encoded in the gravitational-wave background, there's not only the details of inflation but also the whisper of other universes breaking through the cosmic friction?
