I was just wondering about something, and maybe someone can clue me in. I was thinking about how the Large Magellanic Cloud and Small Magellanic Cloud orbit our own galaxy. And I was thinking... I wonder if there are tidal forces at work? I mean, the same way that the Moon causes high tides and low tides on the earth. When a small galaxy orbits our own, does it slightly stretch out our galaxy, like a high tide?
