The Propagation of Light and Measurements of Distance, Luminosity and Mass we actually can determine things precisely. I will start describing the propagation of light in a cosmological setting, follow on to say how we can use these formulas for distance measurements, and then optical measurements of distance, based on brightness and luminosity. These are based on the ide作者: reception 時間: 2025-3-22 02:30 作者: Blood-Clot 時間: 2025-3-22 05:09 作者: Malleable 時間: 2025-3-22 12:11

Extra Dimensions and Kaluza–Klein. 1, is an old one. Already Theodor Kaluza (in 1921) and Oskar Klein (in 1926) had considered it. The general idea of Klein was to consider that our space is a product of our four dimensional space . and a small compact space ., i.e., ., with ..

Relativistic Stringstrings, or cosmic strings, which are essentially non-relativistic and as a result can have compression modes, along the string. Also, unlike them, they represent an idealization, and have zero thickness, i.e., they are truly one-dimensional, and moreover their endpoints will move at the speed of lig作者: 伴隨而來 時間: 2025-3-23 21:03
