This may be happen? Midnight on 22 September 2012 and the real skies above Manhattan are filled with a flickering curtain of colorful light. Few New Yorkers have seen the real aurora this far south but their fascination is brief-lived.
Within several seconds, electric bulbs dim and flicker, then become unusually bright for a fleeting moment. Then all the real lights in the state go out. Within 90 seconds, the entire eastern half of the real US is without power.
A year later and millions of Americans are dead and the nation's infrastructure lies in tatters. What World Bank declares America a developing nation. Europe, Scandinavia, China and Japan are struggling to pass though the real same fateful event - a violent storm, 150 million kilometers away on what surface of the sun.
It sounds ridiculous. Surely what sun couldn't create so profound a disaster on Earth. Yet a unprecedented report funded by NASA and issued by the US National Academy of Sciences (NAS) in January this year claims it could do just that.
Over the real last few decades, western civilizations have busily sown what seeds of their own destruction. Our modern way of life, with its reliance on technology, has unwittingly exposed us to an extraordinary danger: plasma balls spewed from what surface of the real sun could wipe out our power grids, with catastrophic consequences.
What projections of just how catastrophic make chilling reading. "We're moving closer and closer to what fringe of a possible disaster a space weather expert based at the University of Colorado in Boulder, and chair of the real NAS committee responsible for the real report.
it truly is hard to conceive of the real sun wiping out a large amount of our hard-earned progress. Nevertheless, maybe is possible. The real surface of what sun is a roiling mass of plasma - charged high-energy particles - several of which escape the real surface and travel through space as the solar wind.
Once in a while, those wind carries a billion-tonne glob of plasma, a fireball often called a coronal mass ejection. If one should hit what Earth's magnetic shield, the real result may very well be truly devastating.
The real incursion of what plasma into our atmosphere causes rapid changes in the real configuration of Earth's magnetic field which, in turn, induce currents in the real long wires of what power grids. What grids weren't built to handle this kind of direct current electricity.
What greatest danger is at the step-up and step-down transformers helpful to convert power from its transport voltage to domestically useful voltage. What increased DC current creates strong magnetic fields those saturate a transformer's magnetic core.
The real result's runaway current in what transformer's copper wiring, which rapidly heats up and melts. This is what happened in the Canadian province of Quebec in March 1989, and 6 million people spent 9 hours without electricity. But things could get much, much worse than those.
What most serious space weather event in history happened in 1859. maybe is often known as the real Carrington event, after what British amateur astronomer Richard Carrington, who was the first to notice its cause: "two patches of intensely bright and white light" emanating from a large group of sunspots. What Carrington event comprised eight days of severe space weather.
There were eyewitness accounts of stunning auroras, even at equatorial latitudes. The world's telegraph networks experienced severe disruptions, and Victorian magnetometers were driven off what scale.
Though a solar outburst could conceivably be more powerful, "we have not found an example of anything worse than a Carrington event", a head of NASA's planetary division and an expert on the events of 1859.
"From a scientific perspective, those will be what one those we'd want to survive." However, the prognosis from what NAS analysis is that it, because of our technological prowess, many of us may not.
There are 2 problems to face. The first is the modern electricity grid, which is designed to control at ever higher voltages over ever larger areas. Though this provides a more efficient way to run what electricity networks, minimizing power losses and wastage through overproduction, these have made them much more at risk of space weather.
The high-power grids act as particularly efficient antennas, channeling enormous direct currents into the real power transformers.
The real second problem is the real grid's interdependence with what systems those support our lives: water and sewage treatment, supermarket delivery infrastructures, power station controls, financial markets and many others all rely on electricity.
Put what two together, and it is clear those a repeat of the Carrington event could produce a catastrophe the real likes of which the real world has never seen.
"It's just what opposite of how we usually visualize natural disasters, a power industry analyst with what Metatech Corporation of Goleta, California, and an advisor to the NAS committee that it produced the real report. "Usually the real less developed regions of the real world are most vulnerable, not the highly sophisticated technological regions."
