... Follow John Michell and Simon de Laplace and compute, using Newtonian mechanics, the radius rM L at which the escape velocity of a test particle in this field reaches the speed of light. This is the radius of a Newtonian ‘dark star’ in higher dimensions. Check that this is exactly the same, in any D ...

... a) How do we know the universe started in a big bang? The galaxies are moving away from us as measured by their Doppler red-shift. The farther ones are moving faster than the near ones. If you run the motion backwards, it looks like everything was in one place at the same time 13.8 billion years ago ...
