Most stuff is never allowed to visit. Various remote sensors and controls probe the alien expanse beyond your secluded prison abode.
You may never leave, or at least, no one has yet successfully escaped to tell the tale. Some have gambled fortunes that such an escape is inevitable in post mortem preservation of a rogue self.
I prefer to think of it as an oasis. A biological sanctuary in a chaotic and uncaring universe. A safe haven able to stave off the oblivion of entropy for at least a few short years, giving the untold complexity of your brain and consciousness that chance to experience itself and the world before inevitably succumbing to the turbulence of the cosmos.
