How did anyone prior to Newton know how to aim a projectile?
We don't have to fully understand something to use it.
I have a couple of theories.
Firstly dark matter/energy are just a place holder that kinda make the maths work for what we see. A bit like calling sqroot(-1) = i - when no such real number exists.
Next, the spacetime continuim is such that all times and places co-exist. Our conciousness just moves from one state to the next (should fit with quantum theory I reckon). Dark matter/energy is just all of that matter and engery which exist at times which are not now hence we cannot see it. All of this should make time travel possible when we do work it all out
Unlike 400 years ago we at least acknowledge that we do not know everything. If you look at the increasing rate at which scientific discovery builds on previous work it should only take one more generation to work it out.
