Gravitational Wave Astronomy: A Decade of Discovery and India's Role
Scientists have found a new way to look at space by detecting ripples in space called gravitational waves, predicted by Einstein.
These waves are caused by massive objects, like black holes, colliding.
The first detection was made in 2015.
Scientists from around the world are working together to study these waves, which is opening up a new way to see the universe.
India is a key player, planning to build a new observatory that will help scientists pinpoint where the waves come from in the sky.
This is giving astronomers a new view of how the universe works and the origins of elements like gold.
Gravitational waves were first detected in 2015, verifying Einstein's theory.
These waves are ripples in spacetime caused by massive objects like black holes.
LIGO and Virgo observatories have detected over 200 signals from black hole collisions.
Scientists use these observations to learn about the universe and test Einstein's theory.
India is building a LIGO observatory to contribute to this international effort.
