Listening to the Universe's Gravitational Waves

Imagine two black holes colliding far away in space—and the ripple of that crash reaching Earth!”

That ripple is called a gravitational wave—a wave in the fabric of space and time itself.

Einstein predicted this over 100 years ago, saying that massive cosmic events would

send these waves across the universe. Back then, it was only theory. In 2015,

scientists detected gravitational waves for the very first time. They came from two

black holes colliding billions of light years away. Incredible, right?

This discovery proved that we can’t just see the universe with light—we can actually *listen*

to its vibrations. It’s like the cosmos is telling us its secrets. So here’s the question:
