Wormholes and Time Travel

- Rupsa Dasgupta, FYBSc

The existence of wormholes is a subject that has been a hot topic of debate and discussion for quite some time now. We have seen them being featured in multiple sci-fi movies like Interstellar. So what exactly is a wormhole, and why is it such an interesting topic to explore?

A wormhole is a hypothetical tunnel through spacetime that creates shortcuts between two distant points in the universe, or possibly even between different universes! Although the existence of wormholes has been mathematically predicted by Albert Einstein in his Theory of Relativity, it still has not been proven or observed yet. In fact, most scientists are skeptical of its existence. But that does not stop us from wondering what possibilities they could offer, if they are out there in the universe at all.
