In search of Einstein’s gravitational waves

(Published in The Nation Pakistan)

It has been a hundred years since Einstein proposed GR, stating that spacetime was curved due to the presence of massive bodies, which change this curvature as they move. This successfully explained and predicted additional physical phenomena, which would be later confirmed through experimentation. For a century this theory has passed every test.

One prediction of GR has been elusive however. That is, the direct proof for gravitational waves – ripples or fluctuations in the fabric of spacetime – caused by accelerating masses – which transport energy as gravitational radiation.
