No No No, the gravity isn't the problem, the magnetism is...
The downside it that it is expensive and the ships tend to only be able to mine 4 or 5 stars before needing to be repaired or replaced. Nippy specialises in neutron star mining, I suggest you ask him if you want to know any other ways.
The actual collection of neutronium is easy, there are a few methods, the quickest is having a ship dive into the centre of the star (heavily shielded) while using gravity wells to weaken the gravity to a level which will prevent too much damage to the ship. Then dragging it away at light speed while refining it, then dropping it off.
How do you use Neutronic Matter to make hull when if you cracked the surface of a neutron star (where I suppose you find it) it would make a giant electro-magnetic storm dissabeling your mining vessel and if that wasn't enough the magnetic forces of a neutron star would take the iron from your blood and strip your ships to the very atoms it's made of, so please explain how you get it, if I knew how to use it I wouldn't need this armor...
Blindness wouldn't be very useful against most Korlonian ships, they have many different types of sensors and can predict enemy actions quite well if all else fails. Their armour is made with large amounts of neutronium (or similar), which is a very dense and very strong material. The main shields (Variable geometry) will block most energy weapons, physical projectiles, and teleporters. There are usually 5+ large emitters with nano-emitters all over the ship.
Seeing that I can use Swarm tactics and blind my enemies and they're EMS (Electro-Magnetic Sensors) I could tacticly win most opponents...I think a war would actually be a struggle between the two empires.
I see, but you do know that all the weapons and armour on my ships are just made to look similar to what the ships would look like if they were real, right? So, in a war against my tpt ships you would easily win, but against what they are meant to be like, you would not be able to do much.
