Does 11-D exist

In theoretical physics, particularly in string theory, the concept of 11 dimensions is proposed, suggesting that the universe could have more than the four observable dimensions (three spatial dimensions plus time). In this framework, the additional dimensions are compactified or not directly observable at everyday scales. However, as of now, there is no experimental evidence to confirm the existence of 11 dimensions, and it remains a theoretical construct. Thus, while it is a fascinating idea within certain scientific models, the existence of 11 dimensions has not been proven.
