Cosmic Magnifying Glasses Catch Gravitational Waves express
Original: "Gravitational Lensing of Gravitational Waves from Astrophysical Sources: Theory, Detection, and Applications"
Heavy objects, like giant magnifying glasses, bend and amplify spacetime waves from distant black holes.

Gravitational waves from colliding black holes can repeat like an echo: flying past galaxies, they bend and arrive twice or three times. This allows us to peer into hidden dark matter and refine the expansion rate of the universe.
🎯 A wave passing close to a massive body can split in two or three, and its copies will reach Earth with a gap of minutes to years — like an echo stretched over time.
