A cosmic emergency

It is said that the universe is expanding at an expanding pace.  Galaxies, stars and particles are being pushed farther and farther apart.  The "or" has gone wild.  And that is not good. The diversity that resulted from the luxurious interplay of the "and" and the "or" is under threat.  And if history is the result of particles, objects etc interacting with each other, history is coming to an end.  And, of course, if time is also measured by these interactions, time is coming to an end as well.  It would thus appear that a worthy cause over the next 20 or so years would be to devise a plan to halt the expansion of the universe.
