Answer to Question 1

The stars are so spread out that collisions between them would be unlikely, but the shock wave set up when nebulae collide would create conditions for a starburst galaxy, which forms stars much faster than normal. Soon the gas and dust would be turned into stars, or heated so much as to be driven out into space.
