Cannibals in space?

Do you know that galaxies interact with each other in space? First of all, do you know that galaxies can move? Our galaxy is also moving even as we speak. What is the big deal if they can move? Well, being able to move, galaxies may interact with each other.

The interaction that I'm talking about is galactic cannibalism. What is it actually? Similar to it's counter part on Earth, galaxies may 'eat' up other galaxies. Sounds scary? Well, it is quite harmless in a sense. Unlike human cannibalism, galaxies that are 'eaten', will not be lost. It will actually merge with the galaxy that 'ate' it. Normally, the solar system in that galaxy will not be affected. But, in some cases, they may collide with other solar system and a major catastrophe will happen. This galactic cannibalism can also cause the galaxy to change its shape. For your information, our galaxy 'ate' another galaxy before. Fortunately, Milky Way is bigger than that galaxy. Thank God we are still here today!



The image above is an example of galactic cannibalism. Galactic cannibalism is a natural phenomena in the universe. So, there is nothing to worry about. It is a common thing in the universe. The good news is our universe is always expanding. Indirectly, the distance between galaxies are further apart. Galactic cannibalism frequently take place when our universe was first formed. Nowadays, galactic cannibalism rarely happen.
