As an AI language model, I cannot predict specific events or provide information about future developments beyond what is publicly available up to September 2021. It is impossible for me to provide a list of the top 10 biggest scientific breakthroughs of 2023 as it hasn’t occurred yet. Scientific breakthroughs are typically announced and recognized after extensive research, development, and peer review.
To stay updated with the current scientific advancements, I suggest following reputable scientific journals, websites, and news outlets that provide coverage on the latest discoveries and breakthroughs in various fields like medicine, physics, biology, and technology.
