低加速度新物理学(MOND):暗物质的替代方案

New Physics at Low Accelerations (MOND): an Alternative to Dark Matter

Mordehai Milgrom

摘要:

我描述了MOND范式,它假定在一定的加速度尺度下偏离标准物理学。从星系动力学中推导出的这种加速度被神秘地发现与由当今膨胀率和“暗能量”密度定义的宇宙加速度尺度一致。我特别强调现象学和批判性的比较与竞争的范式基础上的经典动力学加上冷暗物质。我还简要地描述了非相对论和相对论MOND理论。

英文摘要:

I describe the MOND paradigm, which posits a departure from standard physics below a certain acceleration scale. This acceleration as deduced from the dynamics in galaxies is found mysteriously to agree with the cosmic acceleration scales defined by the present day expansion rate and by the density of `dark energy'. I put special emphasis on phenomenology and on critical comparison with the competing paradigm based on classical dynamics plus cold dark matter. I also describe briefly nonrelativistic and relativistic MOND theories.
