"I'm not exactly sure about" is a phrase commonly used to express uncertainty or lack of knowledge about a certain topic or situation. It implies that the speaker is not completely confident or knowledgeable about the subject at hand.
Scientists use this phrase to acknowledge the limitations of their knowledge and to avoid making false or unsupported claims. It is an honest and humble way to express uncertainty and encourage further research and investigation.
Yes, it is perfectly acceptable for scientists to not be sure about something. In fact, it is a fundamental aspect of the scientific process to acknowledge and address uncertainty in order to gain a better understanding of the world.
Scientists use various methods to address uncertainty in their research, such as conducting further experiments and gathering more data, seeking peer review and feedback from other scientists, and clearly stating the limitations and potential errors in their findings.
No, scientists can never be 100% sure about something. The scientific process is based on gathering evidence and making conclusions based on the available data, but there is always a possibility for new information or discoveries that may change our understanding of a certain topic. Therefore, scientists must always remain open to new ideas and continue to question and test their findings.
