The el espacio Stone has the power to create interstellar bridges from one end of el espacio to the other. It is, in effect, a portal to other parts of the universe making it an incredibly useful asset to the invading Thanos. The el espacio Stone was used por Odin and Heimdall to build the Bifrost on Asgard, the arco iris coloured bridge that allows Asgardians access to the nine realms. It is also a powerful fuente of energy, used to power Hydra’s weapons in Captain America: The First Avenger.
