SUMMARY

The discussion centers on the concept of the universe's boundaries in the absence of a multiverse. Participants assert that if the universe is not infinite, then there is no "outside" to it, as the universe encompasses all that exists. A primer from Live Science is referenced, providing insights into the arguments surrounding the universe's edge and multiverse theories. This conversation highlights the philosophical implications of defining the universe's limits.

PREREQUISITES
  • Understanding of cosmology and the universe's structure
  • Familiarity with multiverse theories and their implications
  • Basic knowledge of philosophical arguments regarding existence
  • Awareness of scientific literature on the universe's edge
NEXT STEPS
  • Research "Live Science universe edge" for foundational concepts
  • Explore "multiverse hypotheses" for contrasting theories
  • Read "philosophical implications of cosmology" for deeper insights
  • Investigate "scientific literature on universe boundaries" for current debates
USEFUL FOR

Philosophers, cosmologists, and anyone interested in the fundamental nature of the universe and the implications of multiverse theories.

I have been trying to think if there is no multiverse and the universe is not infinite than what is on the outside?
 
Physics news on Phys.org
There would be no outside. The universe, by definition, would be all there is.
 
oh thank you
