They're saying tunnels are possible. They didn't say people (or any organic life on Earth) would travel through them. Honestly just encoding any communication

They're saying tunnels are possible. They didn't say people (or any organic life on Earth) would travel through them. Honestly just encoding any communication through them successfully would turn our world upside down. That said, wormholes are a bit of the pet crackpot theory of the scientific community right now. Black holes are definitely a thing. White holes are pure conjecture based on extrapolating math in very hand-wavey ways. And wormholes (i.e. the idea of black/white holes where information can travel between them) are even less plausible.
