Einstein’s earliest formulations of general relativity included a cosmological constant – a kind of anti-gravitational force that played the same role as dark energy – but previous DESI ...

Einstein thought in images ... fudge factor into the equations of general relativity—a cosmological constant. While gravity pulled celestial objects inward, this extra gravitational effect ...

It opened up an entire field of physics, but left Einstein with some nagging questions. The problems of gravity and acceleration would not go away. After thinking about the problems for 10 years ...

Teleparallel gravity is an alternative theory to general relativity, also devised by Einstein. This "other ... without invoking a cosmological constant," Rivera says. Rivera and her colleagues ...

3. Einstein's theory of relativity predicted the presence of ripples in spacetime called gravitational waves. Einstein had already demonstrated that matter can curve space, so it only follows that ...

Most climate scientists agree the world is experiencing a climate crisis. Monte Heil (Daily Bee, Jan. 21, 2025) opines, “If it isn't a crisis for you, then for you it isn't a crisis.” How is that ...

Besides quantum theory, general relativity is one of two pillars of modern physics – our working theory of gravity ... s constant speed to construct the special theory of relativity, Einstein ...
