Right, I was going to tell you to do something to fix that; but, the editing of the post failed and I lost it and got deterred from it by another issue you had. At end of MeteorsWorld constructor, add the following line: 
adjustScore(-score);

Add an int timer field to Rocket class. In if block in act method, add: 
timer = 120;
After if block, add: 
else
{
    if (--timer == 0)
    {
        getWorld().removeObject(this);
        return;
    }

this is what I have. There seems to be something wrong since the game does not switch to the game over screen.

to clarify it doesn't switch over after two seconds and the game just runs without the timer working
