Is the concept of wormhole real?

Could you please elaborate on the concept of a wormhole? Is it merely a theoretical idea, or does it possess any tangible reality? I'm fascinated by the idea of bridging vast distances in space-time, but I'm also aware of the complexities surrounding such a concept. Could you explain the scientific basis, if any, for the existence of wormholes? Are there any experiments or observations that support this idea? And if so, what are the potential implications for our understanding of the universe?
