Invisible stars made of dark matter can masquerade as black holes. A tiny neutron star plunging into one generates gravitational waves with a “chirp,” just like a real black hole merger. But the signal’s sharp cutoff exposes the fake.
🎯 A boson star could be bigger than Pluto’s orbit, yet so diaphanous that an astronaut flying through it would feel only a faint extra weight.
