All OUR efforts so far use chemical rocketry to provide momentum. This

Rocketry should be abandomed and all efforts should be focused on
finding / developing alternatives. After all, no UFO has ever been
seen to use rockets. Good food for thought ...

Obvious question, how to get to those "alternatives" ?

Ironically, the answer can be had from rocketry ! Momentum is obtained
by shooting matter backwards, and the momentum gained is the matter
mass x shooting velocity. Regrettably, the velocity is so very, very relatively low in this case. So, find something with mass to shoot
much faster, say some exotic particle (with mass) shot at something
much, much, much faster, perhaps in the ultimate, approaching or even
equal to light speed. All the momentum your heart desires !

Use Democrats. They constantly spew limitless amounts of lies
and hot air.

Nothing compared to Sh***y Republicans !

Seriously, cations like e.g. Ca++, Fe+++, and especially H+, can be
accelerated via an electric field, etc. I mention H+, because there is
supposed to be some free H2 around in deep space.

some concept of the ion engines already exists,
but are usable only with sufficient long term energy source
and provide low trust, even if they can do so for very long time.

I maintain that improving on this big time, has got to be the plan in
the long term. Chemical rockets just aren't going to cut it. Look how
much is needed to do so very little.

Energy can be nuclear. The matter needed can be extreemly small, if
the velocity is high enough.

Well, catching hydrogen atoms and molecules
from the high quality vacuum would be highly ineffective.
