forms of matter and energy. While the spatial size of the entire
universe is unknown, 31 it is possible to measure the size of
the observable universe, which is currently estimated to be 93
billion light-years in diameter. In various multiverse hypotheses, a
universe is one of many causally disconnected il constituent
