The Search for Gravitational Waves with Resonant Detectorser and Nautilus has given an upper limit of Ω = 60 for the ratio of gravitational wave stochastic background energy density to the energy density needed for a closed Universe, at a frequency of 900 Hz..Plans for the construction of large spherical detectors that should reach, at 1 kHz, a spectral sensitivity on the order of .are reported.作者: 使成波狀 時間: 2025-3-22 00:42 作者: single 時間: 2025-3-22 04:49 作者: 伴隨而來 時間: 2025-3-22 10:41
Special Relativity at Action in the Universeources and gamma-ray burst fireballs have bulk Lorentz factors from a few to several hundreds. A variety of effects then arises, such as the beaming of the radiation produced, light aberration, time contraction and the Doppler frequency shift. I will emphasize that special relativity applied to real作者: 宴會 時間: 2025-3-22 13:15 作者: 裙帶關系 時間: 2025-3-22 19:09
Canonical “Loop” Quantum Gravity and Spin Foam Modelsf Einstein’s theory of General Relativity.
