Cannot build mystical bridge

In go12 I have a hole full of purple crystals, I think I just have to build a very expensive bridge but clicking on it doesn't show anything, is it because my current maximum resources amount isn't high enough ? If so there should at least be a message about it and what is its price then ?

It's actually a Energy/Hard-light bridge from how it looks in the last anomaly.

So I believe it requires the space age to build, which is not in the game yet. So you can't build it yet.

you need to research more, before you get info about the bridge. there will probably be a description when you are in info age
