Why do we assume that the other 6 dimensions that are curled up are spatial dimensions? Could they not be dimensions of time?

The concept of extra dimensions in physics is based on various mathematical models and theories, such as string theory and M-theory. These theories suggest that there may be more than the three dimensions of space and one dimension of time that we experience in our everyday lives. In order to make these theories mathematically consistent, they require additional dimensions to be "curled up" or compactified in order to explain certain physical phenomena. Therefore, it is assumed that these extra dimensions exist and are spacial in nature.
The number of curled up dimensions is not a definite answer and may vary depending on the specific theory or model being used. However, the most widely accepted theories suggest that there are 10 or 11 dimensions in total, with 3 dimensions being extended and observable, while the remaining dimensions are compactified. Therefore, it is estimated that there are 6 curled up dimensions based on these theories and mathematical calculations.
As of now, there is no experimental evidence or technology that allows us to directly observe or experience these curled up dimensions. They are believed to be on a microscopic scale, making them inaccessible to our current level of technology. However, scientists continue to explore and study these dimensions through mathematical models and theories, hoping to one day provide evidence for their existence.
The existence of these extra dimensions is necessary in order to explain certain inconsistencies and unanswered questions in our current understanding of the universe. For example, theories such as string theory and M-theory use the concept of extra dimensions to unify the four fundamental forces of nature and provide a more comprehensive explanation of the universe at both the microscopic and macroscopic level. These dimensions also play a crucial role in explaining the behavior of particles and energy at the smallest scales.
While there are no immediate practical applications of understanding these extra dimensions, the research and study of them have led to advancements in other fields of science and technology. For example, the concept of extra dimensions has influenced the development of new technologies such as quantum computing and advanced materials. Additionally, understanding these dimensions may lead to breakthroughs in our understanding of the universe and potentially open up new possibilities for space exploration and travel in the future.
