At this moment (at least as I am aware of) you can research Graviton level 1, and that's it.
Why not connect the level of Graviton with the firepower of a deathstar?
It has a basic attack value of 200,000.
Why not add another 10% for each graviton level till graviton level 10 is reached and make it 20% increase in firepower and 10% increase in speed when graviton level 11 is researched, and further on.
Reaching that level 11 is a very far goal, but it is something to work to. It gives the deathstar more purpose, also giving it some more speed would make things a lot more interesting.
You could describe this as that researches have found ways to fold space better due to harmonic amplifiers normally used in Gauss cannons (whatever) and that it makes the Deathstar go faster after researching level 11, which basically becomes "Warp Technology".
You could do that, rename it to "Warp Technology" after level 11 Graviton has been researched.
