Graviton Technology is only used for one thing, for the construction of the fearsome DeathStar.
Out of all of the technologies to research, this one carries the most risk of detection during the phase of preparation.

What do the letters in bold mean?

Just that it is very obvious when someone is going for Graviton. Because they have thousands of Sats at their planet.

At least, thats how I read it.

That is correct.

What do you mean? How do sattelites mean graviton technology?

You need 300K of energy to get Graviton. The only way of doing that is by purchasing tons of solar sats.

Oh. Ok. thanks.

yes and it takes you a couple days of building them to have enough. which gives them time to see your sats and attack.

Thats the only bad thing about graviton tech.

i did it in two or three days. as long as youre inconspicuous its easy.

You can do it in 10 seconds. With lvl 4 nanite and lvl 13 shipyard. As long as you have the needed resources.

Solar Satellite
Solar satellites are simple platforms of solar cells, located in a high, stationary orbit. They gather sunlight and transmit it to the ground station via laser.
