Ok so the dark matter takes up space and there is no way to dump it off really. I got like 790 of them and no missions to use it so I would like the space back. Maybe more uses for it like for cash/research points/ artifacts or the like would be great.

The other idea that I had was maybe some sort of time travel/stopping device that allows time to pass that will be equivalent to a certain number of hours of waiting. This could be similar to an energy cube in filling energy but also minerals and research points. Even if it was just like a 2 hour adjustment it would be fun to get and useful when you need it.

It used to take up the same amount of space as regular minerals and he recently dropped the size down to like 1/100 or something like that so 470 would only take up like 4.7

I agree it should be throwawayable but to be honest cargo adds 10 space for like 1 point so it might be a good idea to increase your cargo size.

dont throw any of it away, at higher ranks its invauluble

How High? Im 75 and have yet to get a mission using it O_o

Well currently i have one that uses 77 energy and 20 dark matter, 170 XP gain. AKA incredible energy/XP efficiency, dont have the dark matter to complete the mission though.

Noah, at rank 85 you will get a mission called "Unstoppable Forces". You will churn through your Exotic Matter like butter

Plus, it unlocks a...(ok I wont give it away)... but it will allow a better use for it across the board.
