SUMMARY

The discussion centers on the concept of a second temporal dimension and its implications for our understanding of time. Participants explore the idea that an additional temporal dimension would be orthogonal to the existing time axis, suggesting a complex five-dimensional spacetime framework. The conversation highlights the challenges of conceptualizing such dimensions and their potential impact on the current arrow of time. A reference link to a related article is provided for further exploration of this topic.

PREREQUISITES
  • Understanding of basic physics concepts, particularly spacetime.
  • Familiarity with dimensional analysis in mathematics.
  • Knowledge of the implications of time in theoretical physics.
  • Ability to interpret scientific literature on advanced topics.
NEXT STEPS
  • Research the concept of orthogonal dimensions in physics.
  • Explore theories related to higher-dimensional spacetime, such as string theory.
  • Investigate the implications of multiple temporal dimensions on causality.
  • Read about the current understanding of the arrow of time in physics.
USEFUL FOR

This discussion is beneficial for physicists, mathematicians, and anyone interested in theoretical physics and the nature of time, particularly those exploring advanced concepts in spacetime and dimensional theory.

Hello to everybody. I had brought up the topic of extra spatial dimension in the math sector of the forum and was directed to the physics section for a question to a second temporal dimension.

My questions are the following. would a second temporal dimension run counter to the current arrow of time? What are the implicications of a second temoporal dimension? Any helpful links goes a long way.

Thanks

If you add another dimension, then its direction has to be orthogonal to the 'original' time axis. Consider time as a bead sliding on a straight wire, then the other time has to be sliding on a wire at a right angle to that. I don't know about implications of it off the top of my head, it's hard to imagine a 5 dimensional space-time.
 
Pretty interesting stuff. I suppose if that's the way nature really works though then what we experience would be a result of 5D-space time.
