Hey /sci/, /lit/ here.

Would it be possible for there to be a solar flare so massive, that it completely destroys all electronics on an entire planet? (Not talking about our Sun/Earth.)

How do EMP's even work? Could they erase all digital data on an entire planet?

yes, but unreasonable amount of power would
be required. And many of today's advanced storage devices, even a simple USB, wont have its entire database corrupted by an EMP burst.

even if the EMP burst was powerful enough?

what if the star was something like VY Canis Majoris and the planet was earth-sized.

is there any sort of natural space-phenomena that could erase all digital information and prevent electronics from functioning?

It's a spinning neutron star and its blowing a shiton of electromagnetic energy out of the oles like a big laser beam.

The spin isn't stable though so the beam kind of wombles around really fast sweeping a cone.

There already are more than a dozen pulsars sweeping earth but they are all far enough away it doesn't affect us much.

If one was close enough it could disrupt all communications every time the electromagnetic beam sweat over the earth which would be probably less than seconds apart.

Or if it was really close like a few light years it could vaporize the entire surface

I like it.

And you're saying this could effectively render all electronics/digital information useless?

Yes. It's not so much of a question of magnitude but direction.

>is there emp strong enough to wipe out all digital information?
yes

however, that emp, LIKE I SAID, would be unreasonably powerful. BY THAT, I MEAN THE SOURCE OF THAT ENERGY WOULD HAVE BLOWN THE ENTIRE EARTH IN HALF AND KILLED EVERYONE ALREADY.
so why would we worry about our electronics then?

not blown in half, but realistically
irradiated everything on the surface of the earth
to dangerous levels
if your worrying about EMP doomsday, forget it.
you'll have bigger problems on your plate if it does happen

well the premise that that there's a planet which has, because of solar flares or pulsars(or some other solar phenomenon) had all of its electronics unusable.

so, this planet has effectively been wiped off of the map (or galactic map, so to speak) because any ships that travel there are hit with this EMP burst crash on the surface. no ships are able to leave the planet.

so it's basically been cut off from the rest of mankind. being a barely-habitable arid planet, the people left are now faced with extremely tough survival conditions. they can only utilize machinery as no electronics work.

but i need an EMP that could actually do this.

Well different pulsars emit in different electromagnetic spectrums. So you could have the pulsar be whatever you wanted I guess. It can emit just standard light xrays, gamma rays or in the radio wavelengths.

Gamma rays will defiantly penetrate the atmosphere and houses and stuff, destroy some electrical equipment. Like DRAM chips and cpu cores. Not sure if it would damage hardrives and stuff. Most electronic components are hardened against gamma rays because the equipment itself emits gamma rays. But a powerful enough source would not be stopped by shielding. Military equipment hardened for nuclear blast would probably be okay.

However at this power it is also going to be slowly killing off the human population and giving everyone cancer. the only way to survive long term would be to go under ground or get to the poles maybe in ice huts.

However it could also be in the radio wavelengths and then it would;t be so dangerous to humans. It would be more like a constant radio jamm across the spectrum. Things like wireless cards would be useless. Cell phone towers wouldn't work. Satellites would be down. Radars wouldn't work ect. The only way you could communicate is with fiber optics or shielded cables.

assuming OP is using something like the alcubierre drive, as long as you have the information physically written down as to where earth is, you could just put that into the machine

the drive wouldn't function though, unless you can somehow make it so it doesn't use electricity.
