Dumb question: are wormholes real, or are they just a theoretical speculation that science fiction latches on to in order to explain/justify long distance space

  As far as I understand, wormholes are a valid solution to the equations governing relativity. Our best theories suggest that if a wormhole magically popped into existence, it would simply continue to exist without violating any known laws. It's possible wormholes have existed since the beginning of the universe, and this wouldn't require any revision in our understanding of cosmology. The more thorny question is whether/how wormholes could be created in the "modern universe" where they didn't exist before. My interpretation is that opinions vary widely on this, from "it's impossible because it would take an infinite amount of energy" to "we're pretty sure humans will be making these some day and we have a rough idea how they'll be doing it". Of course, wormholes simply not existing anywhere is also compatible with relativity. None have ever been observed.
