The caption of the query has a mistake, either " a few years " later produce collision, however " a few years " later produce collision. Caption still wants a bit more rigorous. Some caption are not rigorous, be suspected of baleful misdirect public opinion. For instance, have by the soft article that reprints from media insanity, caption is " court decision of court of United States of World Health Organization turns gene is harmful, cui Yongyuan inverts have scientific sex " . But, I consulted the website of World Health Organization, with the network address of judgment of American place court, without discovery the court decision turns gene is careless perhaps the content with pleasant harmful phosphine, have an explanation additionally however. This for the moment no matter, talk again later.
In addition, say the galaxy can happen with other galaxy " collision " , actually this also is not rigorous. "Collide " , sound bully gas, intuitionistic. But, galaxy and Andromeda galaxy are very downy only " contact " , produce acuteness collision basically impossibly. Happen between the sort of star and star violent bump head on, this is impossible almost, the probability that produces this kind of possibility is very small.
Below the big setting that why expands in astrospace whole, can the galaxy happen with other galaxy " contact " ? Because drive the dark energy that the universe expands quickly,this is, fall in the large scale of hundreds of 100 million light-year only, its effect just is compared apparent. Arrived galaxy this administrative levels, not be aware of almost. The galaxy also moves on orbit, control a galaxy to move, the corporeal aggregate that is higher administrative levels -- Ben Chaoxing fastens a group. The galaxy produces orbit across with other galaxy, want to see Ben Chaoxing fasten the control of round gravitation.
