Black hole discovery reshaped astrophysics by proving that some of the universe's most powerful objects cannot be seen directly but can be measured through their effects on space and time. Signals ...

Over the short span of just 300 years, since the invention of modern physics, we have gained a deeper understanding of how our universe works on both small and large scales. Yet, physics is still very ...

How does the universe work? What are black holes, neutron stars, and dark energy? This video attempts to explain astrophysics in one go, covering the birth of the universe, the life cycle of stars, ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the universe. For Joseph Farah, a fifth-year graduate student at UC Santa Barbara ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...
