It's been expected for some time now that active supermassive black holes can turn off star formation in galaxies, by blowing away the dust that causes new stars to grow. As far as I know, this isn't completely understood just yet.physixlover said:Growth of the galaxy stopped,it exploded does this may effect our galaxy

A catastrophic event is a sudden, widespread disaster that causes significant damage or loss of life. This can include natural disasters such as earthquakes, hurricanes, and volcanic eruptions, as well as human-caused events like wars or industrial accidents.
Catastrophic events can disrupt the normal processes of a galaxy, such as the formation of new stars and the growth of black holes. They can also cause changes in the distribution of gas and dust, which are essential for the growth of galaxies. In extreme cases, a catastrophic event could even destroy a galaxy entirely.
There are many possible catastrophic events that could have impacted a galaxy, such as a collision with another galaxy, a supernova explosion, or a gamma-ray burst. The specific event that may have occurred would depend on the characteristics of the galaxy and its environment.
Scientists use a variety of tools and techniques to study the effects of catastrophic events on galaxies. This can include observations with telescopes and other instruments, computer simulations, and analyzing data from previous events. By studying these events, scientists can gain a better understanding of the processes that shape galaxies and the universe as a whole.
Yes, it is possible for a catastrophic event to occur in other galaxies and disrupt their growth. However, the likelihood and impact of such an event would depend on various factors, such as the size and location of the galaxy, and the nature of the event itself. Scientists continue to study these events in order to better understand their potential effects on galaxies.
