galaxy mass

Not gonna lie, I’m gonna be playing ME:A and wondering:

Liara is 700 years now at this point. She is nearing the Matriarch stage, if she isn’t already there. Is she doing well? Did she have a brood of little blue children. Has the years been kind?

Also Grunt would be around 600 years old. Is he ok? Is he eating well? Does he get enough sleep? Is someone providing my tank-son with enough ammo?

Why does this galaxy spin so fast? 

To start, what kind of galaxy is this? It’s hard to tell.. It has dark dust lanes like a spiral galaxy but a large diffuse bulge of stars like a lenticular galaxy. 

Surprising observations show that UGC 12591 spins at about 480 km/sec, almost twice as fast as our Milky Way- the fastest rotation rate yet measured! The mass needed in order to hold a galaxy together that is spinning this fast is several times the mass of our Milky Way. Scenarios as to why this is happening with UGC 12591 include slow growth by accrediting ambient matter, or rapid growth through a recent galaxy collision or collisions. Future observations may be able to help us tell. 

The light we see today from UGC 12591 left about 400 million years ago, when trees were first developing on Earth!

I'm glad I'm not the only one overwhelmed by the crafting system tbh. Every time I open the research and development menu I click around before clicking off and just hoping for the best in fights. Hopefully I can get a hang of it in the future but .... goodness. It's a lot for me to process.

Ok, so I FINALLY figured out the crafting, it just looks complicated when you open it because the game doesn’t really explain it, but it makes a lot more sense once you know how it works. Basically, there are just a lot of steps you have to take - instead of your standard “get 10 iron then press X,” you have to take a few steps before you can actually craft your weapon or armor. Hopefully this will help someone else. None of this is really a spoiler, but I’m popping it under a read more for anyone who wants to avoid any kind of spoilers.
