A new study says that violent space weather that could cost $2 trillion in damage is more common than previously thought
In the years 774 and 993, the Earth was attacked from space.
Not by aliens, but by a natural eventâand it was very, very powerful.
Whatever it was, it subtly altered the chemistry of our planetâs atmosphere, creating trace amounts of radioactive elements like chlorine-36, beryllium-10, and carbon-14.
And those provide the clue to what the event was: Those isotopes are created when high-energy protons slam into our air. That means the source must have been from space.
These must have been huge waves of subatomic particles that slammed into us on those dates. Spikes in the abundances of those elements were found all over the world, including ice cores from the Arctic and Antarctic, Chinese corals, and more. Generating that many particles isnât easy, and only extremely violent events can do it.
Several possible sources have been considered. One candidate is that the Earth got caught in the beam from a gamma-ray burst, the mind-crushingly powerful demise of a very high mass star. I wrote about this being the possible cause of the 774 event in an earlier article. However, GRB impacts donât usually create 10Be due to the detailed physics of the blast, so that makes a GRB as the source shaky.
Plus, theyâre very rare events, so having two happen in as many centuries is extremely unlikely (I didnât know about the 993 event when I wrote that article, or else I wouldâve been a lot more likely to wonder about other sources).

that would throw cold water on carbon-14 dating prior to 700 eh?No, as a matter of fact, it wouldn't.
But - BREAKING! MUST SEE! And then THIS happened! Click here to see what happens next - PERFECT!
How come it didn’t kill Mohammed before his cult really started taking off?
The Vikings caused global warming?
Seriously though, the article didn't make any link between the events it discusses and the Vikings, or global warming. I think you are making unsupported leaps.
You’re too late. It’s already a movie....................

Interesting post blam... thanks.
Hoax theory by a white man to detract from #blacklivesmatter.
>> How come it didnât kill Mohammed before his cult really started taking off? <<
Kinda hard to affect a stone age cult whose most modern utility is fire and using stones to kill people.
At most, even now they’ve only stolen anything from other more advanced civilizations which they are trying to eliminate and go back to their stone age killing ways.
That might explain why in the 100 years after the death of Charlemagne, Europe had 30 major famines some lasting 2 and 3 years. More details after I get a good night’s sleep.
When the Little Ice Age started, it began without warning -- after generations of the same planting schedules, suddenly the springs were too cold and too rainy. Seeds rotted in the fields, and were also no longer available as food. The European climate still hasn't warmed back up to the prior conditions, as evidenced by abandoned "dark ages" farmsteads at higher altitudes and higher latitudes than are feasible today. At least one such ruined house showed up from *under* a glacier that melted, as the warmist hoaxers claimed, for the first time since the end of the last ice age.
Modern science -- natural science -- begins with two great assumptions:
So far from being the "death of science" these are the foundation assumptions on which natural science is built.
Manly Warrior: "Example- why do tyrannosaur fossils have sharp teeth?
Because they ate flesh....
No facts in evidence, and science, like jurisprudence, must base facts on evidence, not appearance, anecdotals or similarity."
But there is tons of evidence supporting the idea of Tyranisaurs as flesh eaters, beginning with sharp, pointy serated teeth, like steak knives.
Anywhere such teeth are found in nature today, they belong to flesh eaters.
Herbivore teeth are very different.
But perhaps it will ease your mind to be reminded that anything science can observe is called a fact.
Confirmed explanations of facts (i.e. evolution) are called theories.
Flesh eating Tyranisaurs is a theory, but when a broken Tyranisaur tooth is found in the bone of a Herbivore, that makes it more than "just theory".
