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.

Answer to Question 2
