Avengers Infinity War was all the buzz this weekend and the reason I didn't make a post was because I didn't want to spoil it for anyone.
Well, during the ending half of the avengers began to evaporate and we all thought they died but there was one thing I noticed. Black Panther and Spiderman also evaporated but they both have sequels coming out in Phase 4 which means that they have to come back somehow. The most likely possibility is that they were transported to the Soul World because this happened in the comics which means that they might defeat Thanos some way to save them.
Another possibility is that Doctor Strange said that there were 14 million alternate futures and they only survived one which means that maybe when everyone dies they get stuck in a time loop and they keep trying until they get their desired outcome.
