Multiverse Technologies

Hypothetical devices and systems that would allow us to detect, communicate with, or even travel to other universes within the multiverse. These technologies include multiverse telescopes (that would detect signatures of other universes in the cosmic background), multiverse communication arrays (that would send signals across the universal divide), and the ultimate dream: multiverse portals (that would let us step into other realities). None of these exist, and most physicists doubt they ever will. But the concept is irresistible: technology that could let us visit universes where we made different choices, where physics is different, where life is different. Multiverse technologies are the ultimate expression of human restlessness—never satisfied with the universe we have.

Multiverse Technologies Example: "He read about hypothetical multiverse technologies and dreamed of visiting a universe where he'd become an astronaut instead of an accountant. In that universe, he was floating in space, looking at Earth. In this one, he was looking at spreadsheets. The technology didn't exist, but the longing did. Some longings are their own technology."
