<P> The Universe appears to have much more matter than antimatter, an asymmetry possibly related to the observations of CP violation . The Universe also appears to have neither net momentum nor angular momentum . The absence of net charge and momentum would follow from accepted physical laws (Gauss's law and the non-divergence of the stress - energy - momentum pseudotensor, respectively) if the Universe were finite . </P> <Table> <Tr> <Th> Constituent spatial scales of the observable universe </Th> </Tr> <Tr> <Td> This diagram shows Earth's location in the Universe . </Td> </Tr> </Table> <Tr> <Th> Constituent spatial scales of the observable universe </Th> </Tr> <Tr> <Td> This diagram shows Earth's location in the Universe . </Td> </Tr>
