Evidence?

And what keeps them precessing?  A rotating galaxy will have a certain
angular momentum vector (magnitude and direction) at any point in time.
For precession to take place, the angular momentum must be constantly
changed since the angular momentum is constantly changing.

From: https://en.wikipedia.org/wiki/Angular_momentum

"In physics, angular momentum (rarely, moment of momentum or rotational 
momentum) is the rotational analog of linear momentum. It is an important 
quantity in physics because it is a conserved quantity -- the angular 
momentum of a system remains constant unless acted on by an external 
torque."

>Where does ANY energy "come from"?

I'm asking where the TORQUE comes from, not energy!
