SUMMARY
The discussion confirms that in a positively curved universe, gravitational waves would indeed travel around the universe and return to their starting point, similar to light. This concept is rooted in the principles of general relativity, which govern the behavior of gravitational waves. The idea was sparked by a podcast featuring a cosmologist who explained the implications of a positively curved universe, emphasizing the spherical nature of such a cosmos.
