This NASA update below tells us about a time in the near future when the whole civilization will take the form of an ancient civilization as no electronic device will work around the full world.
Subsequently, the army of black banner may come out of Khurasan. No power will be able to stop them and they will finally reach Jerusalem where they will erect their flags. As mentioned in the hadith:
"Related by Abu Hurayrah: The Prophet Sallallahu ‘Alaihi Wa Sallam said: "(Armies carrying) black flags will come from Khurasan (Afghanistan). No power will be able to stop them and they will finally reach Jerusalem where they will erect their flags." (Tirmidhi)"
In other narrations we find that in the time of dajjal muslims will use horse, rather than tank: it will happen as because no electronic device will work round the world.
"................................................. .................A cry will reach them: "The Dajjal has taken your place among your offspring." So they will throw away whatever is in their hands and go forward, sending 10 horsemen as a scouting party. The Prophet said, 'I know their names, and the names of their fathers, and the colors of their horses. They will be the best horsemen on the face of the earth on that day." (Ahmad, Muslim).
NASA: Solar storm to hit earth in 2013

NASA scientists predict a solar storm will hit the earth in 2013 mostly affecting electronic devices leading to a major catastrophe.
The once-in-a-generation storm, caused by extremely high levels magnetic energy released by solar flares, "will disrupt communication devices such as satellites and car navigations, air travel, the banking system, our computers, everything that is electronic," says Richard Fisher, head of NASA's Heliophysics Division, quoted in a June 14 Daily Telegraph article.
"Large areas will be without electricity power," says Fisher who emphasizes that the emergence of the storm is certain, though its degree of severity cannot be accurately foretold.
The National Academy of Sciences warned two years ago that a strong solar storm could cause "twenty times more economic damage than Hurricane Katrina," which devastated US Gulf of Mexico coastal city of New Orleans in 2005, killing thousands and living an estimated damage of over $125 billion.
According to Fisher, the storm, which will cause the sun to reach temperatures of more than 10,000 F (5,500 C), occurs "only a few times over a person's life."
Every 22 years, according to the report, the Sun's magnetic energy cycle reaches its highest level as the number sun spots - or flares - peaks every 11 years. These two events, says Fisher, "would combine in 2013 to produce huge levels of radiation."
In recent months, NASA's Solar Dynamics Observatory (SDO) has offered unique photos of sun spots, which release a vast amount of energy as they light up.
