I checked the MasterTechDefs.xml file and found the base cost for Mass Manipulation is 2380 research points.  I also saw that it is a capstone, which is a tech that comes at the end of a line of research and can be researched multiple times.  They have high research cost.

Most of the other capstones had research costs with 4 digits.  Two had 3 digits, and one cost only 2 research.  There probably needs to be a review of the costs to be sure they are correct.

I don't know what is going on. It looks like you are getting late game weapon techs early in the game. I would not research them early in the game as it'll consume all your research for at least 50 turns.
