The maximum speed achievable by Blacklight Biotechnology's nuclear power engine could accelerate the spaceship to one-tenth the speed of light, which was equivalent to thirty thousand kilometers per second. The distance between the two designated points was 1115 light-years, which meant close to eleven thousand years of journey.

Under the distorted time-space law of the subspace, it would only take up to two years for the Blacklight spaceship to reach Kepler-642b.

It was a terrific speed.
