The spacecraft will move faster (almost unlimited) in the mission depending on the Mass also with an minus next to the “Massive” environment. (Bomber type not affect)
The spacecraft will move slower (Slower than the Yellow Sun but not more slow like Bomber type spacecraft) in the mission. Still depending on the Mass also with an plus next to the “Massive” environment. (Bomber type not affect)
Here is the picture of the Suns from small to big:
Moreover, the color of a star is determined not only by temperature of a star, but also the phase of a star.
This classification is only applied for main-phase stars. Supergiant stars’ color is based on many aspects. If you want to make stars become realistic, should you mention those stars too ?
Also, CIU only contains main sequence stars.
Drawf stars (expect black drawf stars), neutron stars, and theoritically stars such as black drawf stars should be added too.
Not really.
The black sphere of a black hole you can see is the event horizon space. All the mass of a black hole is contained in a singularity. No one know what exactly a singularity is, both the density or what it really is. Based on Theory of relativity, a black hole is a point in the space-time, that means the density of a black hole is infinity kg/m2.
Based on Quantum mechanics, a singularity of a black hole have mass and space, but of course, so dense that are no bigger than a nanometer of sphere.
Compared to infinity of course is impossible, but compared to a singularity of a black hole in Quantum mechanics, neutron stars are way less denser, both in the total mass and the density.
Of course a spacecraft is big nearly as a neutron star, but way less denser.
i also think due to huge gravity, there will be no planets around these stars, if they were there (if close enough) will be torn apart, forming an asteroid belt.
