The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

A RATHER glib distinction is often made between the two pillars of modern physics. Quantum mechanics is the physics of the very small, while general relativity is the physics of the very large. That’s ...

Sometimes the biggest puzzle in physics seems like the worst relationship in the universe. Quantum mechanics and general relativity are the two best theories in physics, but they have never been able ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

Introduced to the world in 1915, Einstein's general theory of relativity radically changed the Newtonian model of gravity. General relativity introduced the concept of mass warping the very fabric of ...
