Web10 apr. 2024 · We use a string T-duality corrected pair of regular black holes to construct an Einstein-Rosen (ER) bridge with the wormhole throat proportional to the zero-point (Planck) length. This may be a geometric realization of quantum entanglement for particle/antiparticle pairs. We point out that for an extreme mass configuration consisting … WebIf you stumbled upon a black hole and found yourself falling feet-first toward its center, then as you got closer, the black hole's force of gravity would grow astronomically. . . . the speed required to escape a black hole is greater than the speed of light itself. . . . light travels at exactly 299,792,458 meters per second in a vacuum and is the fastest stuff in the universe. Web15 feb. 2024 · These show that the measured amount of dark energy in the Universe can be accounted for by black hole vacuum energy. This is the first observational evidence that black holes actually contain vacuum energy and that they are ‘coupled’ to the expansion of the Universe, increasing in mass as the Universe expands – a phenomenon called … highest temperature in darwin
