I read somewhere (if someone remember it, please tell) a short history about life in neutron stars. It would be incredible fast due to the abundance of energy, with the evolution from 'stone age' to computer age happening in milliseconds. Due to being in a deep gravitational well, such life and life inside a star are forever isolated from us. Unless they discover a way to use solar flares, in fact, perhaps solar flares are their way to escape the surface of the sun.

There's also enormous time dilation, they would appear to be moving very very slowly from our POV. It would be magical if both those phenomenon exactly counter each other (I have not run any numbers, but my instinct tells me time dilation will win out).

  I think a neutron star would have time dilation below 2x. Would be interesting at our time scale, but on the order of magnitude we're discussing of the increased chemical speed i think it would just be noise.

    A neutron star is right on the edge of being a black hole, which has infinite time dilation. A neutron star should have very very high time dilation.

      There is a big difference between infinite and very high gravity. Neutron stars have only about 50% time dilation on the surface, as the surface is at about 50% their Schwarzschild radius.

        > the surface is at about 50% their Schwarzschild radius Don’t you mean 100%? From what I can tell, the radius of a neutron star is about twice its Schwarzschild radius. https://www.aanda.org/articles/aa/pdf/2001/46/aah3021.pdf https://www.aanda.org/articles/aa/pdf/2001/46/aah3021.pdf

        So...50%?

Dragon's Egg [1] and Starquake [2] by Robert L. Forward are both hard sci-fi novels about fast-moving life on a neutron star. I enjoyed both of them, especially the xenobiology and xenoarcheology.

  Flux [1] by Stephen Baxter is also about the inhabitants of a neutron star. Hard sci-fi, but maybe not quite as Hard as Dragon's Egg so far as I recall. [1] https://en.m.wikipedia.org/wiki/Flux_(novel) https://en.m.wikipedia.org/wiki/Flux_(novel)
