Different number of time dimensions

In summary, the conversation discusses the possibility of adjusting the equations of General Relativity and Quantum Mechanics/Quantum Field Theory to different numbers of spatial and time dimensions. While classical GR equations do not depend on the number of dimensions, QFT equations may be affected. The provided link may offer more information on the topic, including the cases of T=0 and T>1.

I am layman, so I can't find an answer on my own.

Suppose, on low energies space is (locally) pseudo-euclidean with the number of spatial dimensions S and time timensions T

In our universe S=3 and T=1

My question: is it possible to 'adjust' equations of GR and QM/QFT to the different S and T? Are there any "no-go" things (like orbit stabilty which, for T=1, is possible only if S=3)? What if T=0 or T>1?

Equations of classical GR do not care about the number of spacelike/timelike dimensions.

For QFT, it's not so trivial. Path-integral equations do not care about that either (at least formally), but that does not seem to be enough.

Not a direct answer, but

might be of help. The cases T=0, T>1 are mentioned as well.

What is the concept of having different number of time dimensions?

The concept of different number of time dimensions refers to the idea that there may be more than one dimension of time in the universe. This means that time may not be a linear progression, but rather a multi-dimensional construct that can be experienced in different ways.

How is the concept of different number of time dimensions relevant to scientific research?

The concept of different number of time dimensions is relevant to scientific research because it challenges our current understanding of time and how it operates in the universe. It opens up new possibilities for understanding the nature of reality and can lead to groundbreaking discoveries in various fields of science.

What evidence supports the existence of different number of time dimensions?

While there is currently no concrete evidence for the existence of different number of time dimensions, some theories in physics, such as string theory and M-theory, suggest the possibility of multiple dimensions of time. Additionally, some experiments have shown anomalies that could potentially be explained by the existence of multiple time dimensions.

How would having different number of time dimensions affect our daily lives?

If there were indeed multiple dimensions of time, it could have a profound impact on our daily lives. It could mean that time travel is possible, that there are alternate timelines, or that our perception of time could vary based on the dimension we are experiencing. It could also have implications for how we understand aging and the passage of time.

What are some potential applications of understanding different number of time dimensions?

Understanding different number of time dimensions could have numerous potential applications, such as developing new technologies for time travel or creating a better understanding of the universe and its origins. It could also lead to advancements in fields such as quantum computing and artificial intelligence, as well as providing insights into the nature of consciousness and reality.
