SUMMARY
The universe is not expanding "into" anything; rather, it is undergoing metric expansion. This concept indicates that the distances between galaxies are increasing, but this expansion does not imply a movement into a pre-existing space. The discussion emphasizes the importance of understanding metric expansion as a fundamental aspect of cosmology.
PREREQUISITES
- Basic understanding of cosmology
