5 giorni fa · Describing the dynamics of an object falling headlong down a black hole’s maw is a task for Albert Einstein’s general theory of relativity. Einstein used this theory more than a century ago...
4 giorni fa · Oxford University scientists have confirmed a major prediction of Einstein's theory of gravity, providing the first observational evidence of a 'plunging region' around black holes. NDTV World...
1 giorno fa · A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. [2] Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
2 giorni fa · At speeds that are a substantial fraction of the speed of light, the framework of Newtonian mechanics no longer suffices to describe many physical phenomena. Instead, one must start to take into account Einstein's theory of special relativity, which deals with the "special" case of physics in the absence of gravity. The more "general" case of general relativity takes ...
5 giorni fa · Tests of general relativity serve to establish observational evidence for the theory of general relativity. The first three tests, proposed by Albert Einstein in 1915, concerned the "anomalous" precession of the perihelion of Mercury, the bending of light in gravitational fields, and the gravitational redshift.
3 giorni fa · We begin the story with the birth of philosophy in ancient Greece in the sixth century BC and end in the twentieth century with Einstein’s revolutionary theory of gravity. Along the way, we will examine the enormous influence of Aristotle’s philosophy on Western thought, the revival of magic in the Renaissance, and the emergence of a new ...
