General relativity has made several important predictions that have been confirmed through observation and experiment:
Gravitational Lensing: Light from distant stars is bent as it passes near massive objects, like galaxies or black holes. Time Dilation: Time runs slower in stronger gravitational fields. This effect has been confirmed by precise measurements using atomic clocks. Gravitational Waves: Ripples in spacetime caused by accelerating masses, such as merging black holes or neutron stars. These waves were first directly detected by the LIGO experiment in 2015.
