中文简介:
在讨论再次转向黑色天体(尤其是黑洞)之前,引入了狭义相对论的最后一个关键概念,这些天体体现了学生在之前的讲座中了解到的相对论效应。新概念涉及在空间和时间的坐标系中描述事件。给出了空间和时间如何通过度量的符号变化在史瓦西半径内反转的数学解释。广义相对论的证据来自天文物体。讨论了海王星作为广义相对论证据的预测存在和随后的发现,并介绍了恒星质量黑洞。
课程简介: One last key concept in Special Relativity is introduced before discussion turns again to black celestial bodies (black holes in particular) that manifest the relativistic effects students have learned about in the previous lectures. The new concept deals with describing events in a coordinate system of space and time. A mathematical explanation is given for how space and time reverse inside the Schwarzschild radius through sign changes in the metric. Evidence for General Relativity is offered from astronomical objects. The predicted presence and subsequent discovery of Neptune as proof of General Relativity are discussed, and stellar mass black holes are introduced.
关 键 词: 黑色天体; 相对论效应; 恒星质量黑洞
