I do not wish to frighten you by this statement, only I read a very interesting article today about space and ‘cannibal galaxies’ on HOWITWORKSDAILY.COM.
What I understand is that very large galaxies with equally large gravitational pull suck in galaxies, some even millions of light years away, and feed off them to become even stronger. This contrasts enormously to smaller galaxies, which grow by the continuous addition of gas and dust to them.
The two larger galaxies merge after being dragged together and this spectacle is a feast for the eyes!
The closest place this is happening to us on Earth at the moment is at the ‘Sagittarius Stream’ on the edge of the Milky Way galaxy. It is a stream of rock, dust and other debris being expelled from a collision and there is a trail of this debris, leading back to the source of the collision in the Sagittarius Dwarf galaxy.
However, space is coming for us in around 4 billion years time, when the Milky Way will collide with the Andromeda galaxy. So beware, this may allow us to see more stars, less stars or just die!
Keep your eyes open for my next post,
