The slower growth of gravitational wells and the accelerating expansion might share the same underlying cause.” In so many ...

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

A prediction of the gravitational waves produced by interacting black holes achieves high precision and demonstrates the link between general relativity and geometry. Read the paper: Emergence of ...

The general theory of relativity, Einstein asserted, was now complete. The month leading up to the historic announcement had been the most intellectually intense and anxiety-ridden span of his life.

When the author did the first velocity formula derivations in “General Relativity: Effects in Time as Causation” [1], the author felt the explanations for the appearance of the 2 spatial and the 3 ...

To obtain a basic understanding of the key concepts of special and general relativity, ... You may bring one 8.5″ by 11″ sheet of formulas for each one-hour exam, along with your formula sheets from ...

With the arrival of Einstein’s theory of special relativity in 1905, a range of concepts were introduced that began to unveil the stranger elements of relativistic effects. Among these were length ...

Special relativity and general relativity. Special relativity tells us that no privileged reference frames exist. If I am traveling at 60 mph (100 km/h), and you are standing still, our difference ...

This is the basic difference of special relativity from the theory of general relativity, which may assume observers in accelerated motion. ... of frequencies of light emitted by high-velocity sources ...
