However, Dappiaggi and Lang have shown that the quantization based on F and Gcan be generalized to curved space-times only under restrictive assumptions on the topology of the space-time manifold [24]. WebMar 31, 2024 · A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. The first telescopes focused light by using pieces of curved, clear glass, called lenses. So why do we use mirrors today?
