Unlocking the secrets of the first quasars: How they defy the laws of physics to grow
In an article published in the Astronomy & Astrophysics journal, new evidence suggests how supermassive black holes, with masses of several billion times that of our sun, formed so rapidly in less than a billion years after the Big Bang......»»
Predicting the next supernova explosion: New simulations reveal the physics of supernova shock breakout
Stars with masses between 10 and 30 times that of the sun, in their final evolutionary stages, form an iron core that ultimately collapses into a neutron star. This collapse releases a tremendous amount of gravitational potential energy through neutr.....»»

Improving hurricane modeling with physics-informed machine learning
Hurricanes, or tropical cyclones, can be devastating natural disasters, leveling entire cities and claiming hundreds or thousands of lives. A key aspect of their destructive potential is their unpredictability. Hurricanes are complex weather phenomen.....»»
To invent the wheel, did people first have to invent the spindle?
The physics of spinning objects may have seeded concepts key to the wheel. Twelve-thousand years ago, people in a coastal village in the Levant used stone weights on their spindle.....»»
Redefining net zero will not stop global warming, scientists say
In a study, led by the University of Oxford's Department of Physics and published 18 November in Nature, an international group of authors who developed the science behind net zero demonstrate that relying on 'natural carbon sinks' like forests and o.....»»
Physicists think they may know the key to unlocking time travel
