If the combined force of gravity of the independent

milky-way is not collapsing by its [own] gravity. Our
solar system works and stays together because of the
gravity of the sun, and the kinetic energy of each
orbiting object is in balance. So, how can the
combined gravity of the milky-way change the course
of another speeding galaxy that is in the course of
moving away. Logically thinking, the colliding
galaxies are independent systems and just happens to
be moving in the colliding paths. Hence, the event is
no problematic in the environment of recycling
universe.
Actually, such behavior kills recycling Universe, since said galaxies proceed on forever, never getting turned all the way back.

“Actually, such behavior kills recycling Universe, since said galaxies proceed on forever, never getting turned all the way back.”
Quite a contrary, galaxies are make-up of billions of stars, and in the observed Milky-Way, stars are self-destructing all the time. Hence, providing recycling matter for the cooling process. Will galaxies eventually cease functioning; I found no reference to this fact. However, the science does not know the extent of the universe beyond of the observable size, which seems to be limited to buy the current observing techniques.
