What Are the Speed and Energy Density Limits of Dark Matter?

Click For Summary
SUMMARY

The discussion centers on the misconceptions surrounding dark matter and its relationship to the universe's origin. It is established that dark matter follows timelike worldlines, similar to ordinary matter, and does not break physical laws by traversing spacelike intervals. The conversation also emphasizes that current theories about the universe's creation are speculative, with no definitive evidence supporting the notion that it originated from nothing or had a specific beginning.

PREREQUISITES
  • Understanding of dark matter and its properties
  • Familiarity with spacetime concepts in physics
  • Knowledge of timelike and spacelike intervals
  • Basic grasp of cosmological theories regarding the universe's origin
NEXT STEPS
  • Research the properties of dark matter in astrophysics
  • Study the implications of timelike and spacelike intervals in relativity
  • Explore current cosmological models of the universe's origin
  • Investigate the philosophical implications of the universe's existence and creation theories
USEFUL FOR

Physicists, cosmologists, and anyone interested in the fundamental nature of dark matter and the origins of the universe.

I have been wondering about how the universe created itself from nothing and it seems in spacetime, the time dimension must have come first followed by multidimensional space. Following this, matter and dark matter must have been created. While matter and dark matter both underwent timelike expansion, dark matter had the liberty to break physical laws and go through spacelike intervals. IF that is true, what is the speed limit and energy density limit for dark matter?

It isn't. Dark matter follows timelike worldlines just like ordinary matter.
 
I'd like to correct the misconception that the universe was created from nothing. Current theories regarding the origin of the universe are tentative guesses at best. Despite what you commonly hear or read, we have pretty much no idea if the universe even had a beginning or if it's existed for an infinite amount of time.
