The Accidental Telescope: How Spacetime's Warped Mirror Reveals the Infant Universe

Albert Einstein predicted that massive objects could bend light, but it was a dismissed idea that transformed astronomy. Now, astronomers use entire galaxies as natural telescopes, warping spacetime to magnify and study the universe's earliest and most hidden objects.
