From its perspective it would get hit by interstellar gas at relativistic speeds which would at the very least spall atoms from the surface.

- m0zg 6y agoGood point. So unless there's gas moving in the same direction at a similar speed, the object would, over a sufficiently long period of time, be slowed down by this gas.
- the8472 6y agoThe issue is that the ISM is incredibly thing. So it's one of those multiple incredibly large by incredibly small number cases and intuition doesn't work, you'd have to do the actual math. I.e. the timescales could be large enough that if some process could create such an object they could still cross between galaxies.
