A black hole can be a wormhole, but we’ll never know
Many individuals have daydreamed about time travel throughout the years, and because of this, scientists have tried to theorize its possibilities. It has been a topic in many movies, as well as before science itself. In general relativity, Einstein came up with the theory of wormholes like rips in time that would allow people to either time travel or go through different universes; however, there is still no evidence backing this idea up.
In accordance with these theories, black holes might also be wormholes. Both would have the same core functions and features, but how it affects light passing through it is a key difference. It’s impossible to tell the two apart from the outside. So, if anyone out there wants to speak up and let us know for certain… we’re all ears!
