Building Graviton Science Help!!

[Scotty_XS]

Just wondered when you build enough solar satelites to research graviton science.
Then get attacked like days after its been fully researched, if you get attacked and lose all your satelites , if you shoot down to minus energy, or if you only need the energy once, and then once researched, can afford to lose your satelites???
Thanks, in advance.

Hello mate,

You need the 300 000 energy only to start the research. Then you won't need the satellites anymore and you can recycle them.

its better to get them destroyed cause they just add more points and make good recycling for raiders.
