Yes, the ball can touch the net during a serve in volleyball as long as it goes over the net and into the opponent's court. However, if the ball hits the net and does not go over, it is considered a fault and the serving team loses the point.

No, the results of the double ball experiment do not match. This is because the experiment is based on the principles of quantum mechanics, where particles can exist in multiple states at the same time. Therefore, when the experiment is conducted, the double ball can be in two different states simultaneously, leading to different results. This phenomenon is known as quantum superposition and is a key aspect of quantum mechanics. **

It seems like there may be a typo in the question as both options are the same. If the question is meant to ask whether the ball belongs to Bastian, then the correct phrasing would be "Is it Bastian's ball?" This question implies ownership of the ball by Bastian. **
