Einstein introduced two main postulates in his special relativity theory. The first postulate is about the laws of physics in inertial frames of reference. According to Einstein, the laws of ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

Dark matter, dark energy, the Hubble tension: underpinning these theories is Einstein’s general theory of relativity, which treats space and time as a unified “spacetime” and considers ...

Ten years before general relativity, Einstein came up with special relativity ... Dr Aravind Vijayaraghavan reveals how the second law of thermodynamics explains the rise and fall of all things ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

When it comes to space travel, Albert Einstein's theory of relativity is a major inconvenience. With the laws of physics (currently) prohibiting faster-than-light travel, velocities are limited to ...

On March 14, 1879, Albert Einstein was born in Ulm, Germany. His thinking revolutionized physics and turned the scientific ...
