I've found an estimation for interstellar electron density which ranges from $3.0 \times 10^4$ electrons per cubic meter (pcm), to $5.0 \times 10^4$ electrons pcm close to the galactic plane. ...
If you assume an interstellar spacecraft of 100 m in diameter traveling to the nearest star - that ship would plow through 3 x 10^20 m^3 of interstellar space. At 0.5 c the energy release of such a ...
Assuming that a planet with an atmosphere already existed which orbits at the radius of the termination shock of a star, what would happen to it over time? As a follow-up, would it be possible for a ...
