Can Wormholes Exist in a Flat Universe?

Click For Summary
SUMMARY

Wormholes, theoretical passages through spacetime, could enable faster-than-light (FTL) travel by creating shortcuts in the fabric of spacetime. Despite the universe being globally flat, local curvatures around celestial bodies allow for the existence of wormholes. The misconception that wormholes must resemble tunnel-like structures is clarified; they are defined by their two mouths, which are topologically spherical. Thus, wormholes can exist in a flat universe by demonstrating local curvature without altering the global curvature.

PREREQUISITES
  • Understanding of general relativity and spacetime concepts

Its said that a wormhole could allow effective FTl travel by creating short cuts in the fabric of space tme. but if the universe is flat , how would this be a short cut? Doesnt the universe need to be curved for that?

You are imagining wormholes (if they even exist) like how they have been depicted in popular books as a tunnel like structure. This is not the case. You only have to identify the two mouths of the wormhole topologically, so that as one enters a mouth (a sphere actually) they exit through another mouth.

Our universe is globally flat, on average, over large distance scales. Locally it is very much curved (around planets, stars, galaxies, etc.). Wormholes, were they to exist, would just be another example of local curvature that doesn't effect the global, average curvature.
