What exactly does the luar angkasa stone do?

The luar angkasa Stone has the power to create interstellar bridges from one end of luar angkasa 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 luar angkasa Stone was used oleh Odin and Heimdall to build the Bifrost on Asgard, the pelangi coloured bridge that allows Asgardians access to the nine realms. It is also a powerful sumber of energy, used to power Hydra’s weapons in Captain America: The First Avenger.
