It was mentioned in a posting that a group of galaxies were being influenced by the galaxies nearest to them.

Myquestion is: Is every bit of matter in the universe affected by all of the matter? Is every galaxy, no matter how far away affected by all of the other galaxies?

Can a star exist in the universe without being part of a galaxy? :roll:

All matter in the universe is affected by all matter in the universe regardless of distance. Have a read of http://en.wikipedia.org/wiki/Gravity

Yes, it's possible. Recently astronomers detected a star being shot out of our own galaxy. The article: http://www.universetoday.com/am/publish ... tml?822005
