Go through a wormhole. It's theorized to lead to a parallel universe... although you probably won't survive being crushed into a singularity.
parallel universe is diffcult as youd have break the speed of light many times over & even the barriers of time to do it.
Start with meditation until you learn OOBE...but we're talking years of practice.
ohh i wish that would work out
there is a possibility, there's the one way ticket of no return, or you should try to look for wormholes around our planet.
