Do solar flares kill Life?

Do they? Yes or no. I just read a artice on a film "The Knowing" and it mentions solar flares. Would we die from a Solar flare. or does it just mess up our Electricity?



No, not really.





Solar flares happen all of the time. Of the few that are pointed our way, most are deflected away harmlessly by the earth's magnetic field. Big solar storms can cause intense aurorae. The biggest solar storm in recorded history caused aurorae as far south as New Orleans and the Florida keys (1859).





The movie 'knowing' hyped up the danger of solar flares, and used that as a premise in their plot. A solar flare of that intensity is fiction (at least for our sun at this point in its life).





Certain scientists have been warning about the fragility of our power grid, and have published a 'worst case scenario' where the power grid loses many of its key transformers. While I agree that there is not enough redundancy built into the power grid, I think their scenario is over the top.





In order to 'kill life', a solar flare would have to be much, much more powerful than any that our sun is capable of producing at this point in its life. We have a really good idea of what sun-like stars do over their lifetimes by looking at other sun-like stars of various ages. The 'knowing' type of solar flare is simply not a probable event for our sun at this point. When it becomes a mira-type variable in a few billion years, then yes.




Nope!





The Knowing is an exaggerated form of fiction and not a reliable source of information. The sun isn't a flare star, it isn't that active anymore and it is very stable unlike what they portray in the movie. Solar maxima are not as violent as what you can see in the movie. EE or everything else there is made up to for entertainment's sake.




Solar flares occur all the time, and are located on the surface of the Sun. Some flares trigger coronal mass ejections (CMEs) which can have effects as far away as Earth, mainly aurorae. A few particularly strong CMEs may affect Earth's telecommunications and electrical grids. They are not a danger to humans. "The Knowing" is just a movie.




Only if the form of life is in space


.


On the planet the magnetic field that covers the earth saves us from that


.


Wipe out


.




Did we all die during the solar maxima of 2000, 1989, 1978, 1967, 1956, 1945, 1934, 1923, 1912, or 1901?




if the ozone fall then yes it can kill us and life




No




they haven't yet. why would they start doing so?





i assume you know that the movie in question is fiction?
