Realistically, actual rights are those that are explicitly expressed by some branch of society and generally represent an agreement by the population as to what types of behavior are allowed. However, when we talk about human rights we are often talking about rights that go beyond any legal definitions as if there are some kind of universal rights that all people have regardless of their cultural beliefs. The U.S. Declaration of Independence refers to these as "unalienable rights". At the universe level the term "rights" may not be appropriate, but I'll stick to that term anyway just to make my point.
Long story short: Can I assume that, as a creature born of the universe, I have the cosmic right to do anything I want?
