    3 days ago · Einstein's theory of general relativity is our best description of the universe at large scales, but a new observation that reports a "glitch" in gravity around ancient structures could force a ...

    2 days ago · Many theorists think of relativity as describing a universe in which past, present and future are all equally real: a static cosmos that just sits there like a big block of spacetime (sometimes ...

    3 days ago · The theory of general relativity—to give Einstein’s theory of gravity its proper name—has precisely predicted them all. But astronomical observations near the “cosmological horizon”—where the farthest galaxies recede from us at nearly the speed of light—suggest gravity may act differently at the very largest scales.

    3 days ago · We recall that, starting from the origin of Einstein's general relativity, the request of Mach on the structure of the theory has been the core of the foundational debate. This issue is strictly connected with the nature of the mass-energy equivalence. This was exactly the key point that Einstein used to derive the same general relativity.

    5 days ago · The twin paradox is a problem that involves relativistic time dilation, a concept from the special theory of relativity. Although the jargon may seem complex, the solution is quite intuitive and leads to a beautiful answer. Also Read: Time Dilation: Why Does Gravity Slow Down The Flow Of Time?

    2 days ago · In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein 's 1905 treatment, the theory is presented as being based on just two postulates: [p 1] [1] [2] The laws of physics are invariant (identical) in all inertial frames of reference ...

    2 days ago · This is due to the incompatibility of quantum mechanics and Einstein's theory of general relativity, regarded as being the best explanation for gravity. In general relativity, gravity is explained as being the geometric curving of spacetime.
