2005 - 2006
Dalibor Janda, a Czech singer, predicted in his song "Všechno na Mars" from the 1980s that in 2005, the people would "shoot" all the (redundant) horses to Mars, and the robots would do the same thing with the people in 2006. Twenty years later, we can announce that Dalibor Janda was wrong, despite millions of crowns that he earned by his CDs, hopefully for the music.

Doubly special relativity and loop quantum gravity were clearly used for some of the most far-reaching predictions. Well, I would probably make a bet that at least 90% of the events above won't occur. The last event in 2040 and the first event in 2050 may be an exception.
