The Authority for Universe Ownership
offers you the chance to buy your own parallel universe. They explain:
Quantum physics dictates that reality is created by observation. There are an infinite number of possible realities, which can be actualised only through observation - an unlimited variety of parallel universes exist in what is known as quantum flux.
In some of these universes the deeds purchased from Buy Your Own Universe will be recognised as legally binding, meaning that you really are the rightful owner of your Universe! Any day a scientific breakthrough in quantum physics may occur that allows you to travel to your universe, through a wormhole for example. This is not fantasy but accepted science.
The price is a bit steep at $9999. But they also offer a free option
Of course, if they're right about the existence of an infinite number of parallel universes in which all possibilities, however improbable, are manifested, then the theory of Quantum Immortality
is true. Meaning that in some existence you're likely to become an eternal, all-powerful being who already owns the universe without needing to go through the Authority for Universe Ownership. (via A Welsh View
