The infinity stones

In the Marvel cinematic universe the infinity stones have played a significant role over the past couple of movies yet they've never really been explained. 6 infinity stones exist the mind, soul, power, time, reality, and space gem. Not much has been explained about the gems only that they each represent a part of the universe. Only 3 have been revealed so far the first was the Tesseract(The mind gem) which Loki used in the Avengers to control Hawkeye and control his army. In Thor the dark world the Aether(The reality gem) was used to try to bring Malekith's army to earth but he was stopped by Thor, Afterwards the gem was taken to the Collector and wasn't seen again until Guardians of the Galaxy. The last was just called the Orb(The power gem) which was used by Ronan the Accuser to fight against the Guardians of the Galaxy but he was beaten.
