The phrase “what is” by itself is incomplete, so it is not possible to answer meaningfully yet. It usually needs a subject, like “what is gravity” or “what is love,” to form a full question.
Clarifying the question
Please add the rest of your question after “what is,” for example:
- “what is AI”
- “what is photosynthesis”
- “what is the capital of Japan”
Once the subject is clear, a precise explanation can be given.
