Yeah it's acceleration, or gravity acceleration/gravity. When PROT came out there were many prot accelerator saves where there were long tubes of ACEL and GPMP used to shoot PROT, creating PLUT and other elements which were collected.
sing it the top speed reaction for protons. they have to move extremely fast. I doubt GRVT will suffice but I might give it a try.
little update on everything.
I experimented a little and saw that with regular Gravitons, you can go up to CO2, but thats about it......
with augmented ones (tmp set to 99) you can produce Plutonium, but still no singularity....... It probably is a problem that could be fixed with a longer acceleration track from gun to target, but I am not a professional....
EDIT:
well, after a small experiment, using a long DMND tube, I found out, that regular GRVT can INDEED produce PLUT.
