Ghost Stars as Precise Cosmic Clocks ⚡ экспресс
Original: "Periodic gravitational lensing by oscillating boson stars"
Invisible stars made of ultralight particles can act like breathing lenses, making distant stars blink with clockwork precision.

Invisible stars made of ultralight particles can make distant stars blink rhythmically. Such objects can be searched for with telescopes, and their discovery would be the first direct test of quantum fields in curved spacetime.
🎯 These invisible objects can pulsate with periods from minutes to decades, and their rhythm directly reveals the mass of the particles they are made of — a mass that is otherwise impossible to measure.
