The conversation between human and AI assistant.
In The Avengers, how does Thor return to earth, given that in Thor, he destroyed the Bifrost Bridge (the wormhole which makes inter-planetary travel possible) at the end of the movie?
Ah, got it. So, what did Thor do with the Tesseract once they defeated Loki and the Chitauri?
Thor took the Tesseract back to Asgard with him. It was revealed in later movies that the Asgardians had been keeping the Tesseract safe for centuries, and were planning to send it to another realm to keep it safe from those who would misuse its power.
