Nostradamus wrote, "Seven months the Great War, people dead of evil-doing." This has been predicted as the conflict in Ukraine caused by Russia's invasion can grow even bigger, resulting in World War 3.
The French mystic cryptically referred to a "light on Mars falling", suggesting that humans could possibly visit the Red Planet in 2023. Elon Musk has suggested that humans will land on Mars by 2029.
Nostradamus' third prediction for 2023 is a new Pope succeeding Francis. He suggested that Pope Francis will be the last true Pope and that the next Pope will create a scandal. He wrote, "In the final persecution of the Holy Roman Church, there will be Peter the Roman, who will feed his flock amid many tribulations, after which the seven hilled city will be destroyed and the dreadful Judge will judge the people. The End."
The French mystic predicted a "Celestial fire on the Royal edifice". This has been interpreted as suggesting that from the ashes of civilisation a new world order will emerge. Other followers of Nostradamus believe this could refer to the "end of times" or the start of a new world order.
Nostradamus' final prediction for 2023 talked about the new alliance of two great powers coming together. The new alignment will potentially be between a strong man and a weak one or even a male and a female leader. However, the alliance's good effects will not be long-lasting.
