All you need is a wormhole, the Large Hadron Collider or a rocket that goes really, really fast.
WORMHOLES – tunnels through space-time that connect black holes – may be a consequence of the bizarre quantum property called entanglement. The redefinition would resolve a pressing paradox that you might be burned instead of crushed, should you fall into a black hole.
Though NASA hasn’t labeled them as portals, and instead calls them Boom Tubes, electron diffusion regions or ‘X’ points, the process of magnetic resonance allows them to exist. This means that an extraordinary’ opening in space or time’ does exist, and NASA has known about them for an undefined duration.
