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

Neutron stars
When the hype for the announcement of the previous GW detection was ramping up, I had a feeling LIGO was about to announce the detection of a neutron-star collision. It wasn’t to be – but in my excitement, I’d written … Continue reading

The nomenclature of uncertainty
Many science articles in the past year dealt with observations falling short of the evidence threshold but which have been worth writing about simply because of the desperation behind them. Has this prompted science writers to think about the language they use? Continue reading

Tracing the origins of Pu-244
Plutonium-244 could’ve come from neutron-star mergers, so knowing its abundance could reveal the rate at which such mergers happen. Continue reading

As the ripples in space-time blow through dust…
The last time a big announcement in science was followed by an at least partly successful furor to invalidate it was when physicists at the Gran Sasso National Laboratory, Italy, claimed to have recorded a few neutrinos travelling at faster … Continue reading
