wormholes

Wormholes are a theoretical method physicists propose for traveling into the past. The article questions whether it is physically possible to alter events once in the past.

New research proposes that Einstein and Rosen's theoretical wormholes may not be cosmic tunnels connecting distant spaces, but rather bridges connecting mirror versions of time within quantum physics. This theory potentially resolves the black hole information paradox and suggests the universe may have existed before the Big Bang.
