Yes, the professor was in two different worlds at the present time.

Explanation:

Introduction:

The question suggests that the professor was present in two different worlds simultaneously. To understand this scenario, let us delve deeper into the concept.

Understanding the Question:

The question implies that there were two parallel worlds or realities existing at the same time, and the professor somehow managed to exist in both of them at once. The task is to determine if this scenario is possible or not.

Exploring the Possibilities:

1. Yes:

The correct answer is option 'A', which states that the professor was indeed in two different worlds at the present time. This suggests that there are multiple dimensions or parallel universes that coexist, and individuals can exist in more than one of these realities simultaneously. If this is the case, the professor may have found a way to navigate between these worlds or simply existed in both simultaneously.

2. No:

Option 'B' suggests that the professor was not in two different worlds at the present time. This implies that there is only one reality, and it is not possible for an individual to exist in multiple worlds simultaneously.

3. Maybe:

Option 'C' implies uncertainty regarding the professor's presence in two different worlds. This suggests that there might be some evidence or indications suggesting the existence of parallel worlds, but it is not definitive.

4. Can't say:

Option 'D' suggests that there is insufficient information to determine whether the professor was in two different worlds or not. This implies that the question lacks crucial details or context necessary for a conclusive answer.

Conclusion:

Based on the given options, the correct answer is option 'A' - yes, the professor was in two different worlds at the present time. However, it is important to note that this scenario is purely hypothetical and speculative, as the existence of parallel worlds is still a topic of scientific and philosophical debate.
