Can gravitational waves be waylaid by gravity?
Yesterday, I learnt the answer is ‘yes’. Gravitational waves can be gravitationally lensed. It seems obvious once you think about it, but not something that strikes you (assuming you’re not a physicist) right away. When physicists solve problems relating to … Continue reading

Onto drafting the gravitational history of the universe
It’s finally happening. As the world turns, as our little lives wear on, gravitational wave detectors quietly eavesdrop on secrets whispered by colliding blackholes and neutron stars in distant reaches of the cosmos, no big deal. It’s going to be … Continue reading

Feeling the pulse of the space-time continuum
Humans have known about the force of gravity since ancient times. Yet, we are still exploring its true nature, how it works, and why it works the way it does. Continue reading
