The universe's resources (sometimes called the cosmic endowment) is the stock of physical resources in the universe currently accessible to humanity.

It has been estimated that, given certain assumptions, humanity could eventually reach ${10}^{18}$ to ${10}^{20}$ stars, which could sustain a total of around ${10}^{35}$ biological human beings, or around ${10}^{58}$ digital human minds (Bostrom, Dafoe & Flynn 2020: 319). (These figures use 'humans' as the relevant metric for convenience only, as are not meant to make any substantive assumptions about moral patienthood.)
