some of my mines are at 35 to ensure a good level of production (aiming at 100 p/hr as a min), but I had to up my resource facilities to level 4 to be able to get them, copper and iron needed a lot early on, hydrogen will be needed once I get into flying a fleet, when I can build a decent ship, still got research to do.
Reading up, suggests I get my scientists into double figure levels to speed it up and aim to use my specialist scientists only on the research they are specialised in, with the initial one acting as their side kick, but level 3 research facility needed to make use of 2 scientists.
People in the chat, say you need patience for this game and LTAO.
I’ve posted a little info on the research and stuff on the in game forum - get to it via diplomacy button at bottom and the tab inside. (it’s the chambers of the government building) lol
Another thing on reading, this game really needs an empire to work together, unlike SP where you can go off making lots of your own killings and simply have lesser members just keep their heads down - all need to be protected! However, having a Bunker and using it helps! lol
