Until the men from the power company come to fix it, usually.
An EMP is quite like a lightning strike in its effect. Anything semiconductor based can probably be popped straight in the bin; semiconductors are fragile to EMP and any large voltage spikes on the earth plane. Switchgear, Transformers and cabling are more physically robust and they may survive but transformers and switchgear may trip, which in turn may or may not require some intervention from the power company. Cables and transformer windings may burn out, in which case the power may be off for quite some time. It all depends on the size of the pulse and the proximity of sensitive equipment.
You haven't been watching Ocean's Eleven, have you....? No, I haven't been (I only know what I can find out by reading the polls on People's Choice Awards), I was just wondering how long you'd have to wait before it would be safe to turn on the car (which was not running at the time the EMP came) without it getting fried (if possible after this EMP). The bad news is that modern cars make extensive use of semiconductor technology in their engine management systems, so after an EMP your car may well not start, whether or not it was running at the time. That goes for all semiconductor based devices. With silicon-based technology, any sizeable EMP, for instance from a nuclear airburst, means Back To The Stone Age.
The largest star in our Solar System is the Sun. Since the Sun is about 93 million miles away from Earth and the speed of light is about 186,282 miles per second, it would take about 8 minutes for light (or any object traveling at the speed of light) to reach the Sun from Earth.
In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
It takes about 3 days for a lunar module to reach the moon from Earth.
About 8-1/3 minutes.
The same as light - approximately 8.3333 minutes.
It can take anywhere from 17 hours to 3 days for a solar storm to reach Earth after being ejected from the sun. The impact of a solar storm on Earth's magnetosphere can cause disruptions to satellite communications, power grids, and GPS systems.

It takes about 8 minutes and 20 seconds for sunlight to reach Earth.
It takes about 8 minutes and 20 seconds for sunlight to reach the Earth.
From the core, photons take about a million years to reach the surface. From there, they are free to travel and only take just over 8 minutes to reach the Earth.
It takes about 8 minutes and 20 seconds for light from the sun to reach the Earth.
It depends on how fast you are travelling.
8 minutes.
