A guide to serious starships and space combat:
1. There are no dazzling beams or bridges packed with explosives. Lasers leave no trails of light in space, and by the time you see one, you're already dead.
2. There are no crazy mechs or boarding actions, unless the ship is docked at a spaceport.
3. There is no thick armor or sturdy structure. Against graviton weapons, armor offers not even the slightest protection. In theory, no material can shield against gravity acting across all ten dimensions of space.
4. There are no so-called energy shields or mysterious energy weapons. Energy is only a relative physical quantity that describes the properties of matter, not an actual entity. So there is no such thing as energy compression, density, or purity. There are only directed-energy weapons and electromagnetic beam weapons.
5. Your face and your speed are your shields! This is a realistic world where the West can't beat the East.
6. A terrestrial planet with a radius of 4,000 to 6,000 kilometers and more than 30% of its land surface habitable cannot be conquered by a measly few thousand marines. And no one would choose to transport tens of millions of soldiers and all their heavy weapons from hundreds of light-years away just to fight you over a patch of land.
