What Life On Earth Will Be Like When Its Magnetic Shield Weakens | Naked Science | Spark

The earth's magnetic field is vitally important to not only the planet, but the life on the planet as well. This field provides the perfect conditions to allow life to thrive on earth as well as protect us from dangerous space debris. But what would life on earth be like in the future when this field gets dangerously weak?

There is some serious fear mongering in the first 30 seconds lol

[@MeganOHowe]

not really historical geological record shows has happened lol

[@2147B]

Thats how they get your comment, mine and many others. Clicks and comments are how these companies gain views/market control and moneeey. Thats why i dont watch television, It has changed in a way that it will kill it's own self. drama/hate/disagreement/fear = the goal for these companies who are only concerned about profit. Spark does it well, atleast they arent blaming it on ancient aliens or lost treasures from fairy tales

Don't be worried people, at the end of the day no one truly even knows what our planet can and cant do. " paleomagnetic studies show the field is about as strong as it's been in the past 100,000 years, and is twice as intense as its million-year average. While some scientists estimate the field's strength might completely decay in about 1,300 years, the current weakening could stop at any time."

[@TealRochelle]

So there broad coverage of time, clearly overlooks why we have not any records of civilizations in past rt? Oh wait we do and we know what happened to them don't we? No infact we deny there patterns of die off happen to be jaded with holes of understanding big gaps and then there they are . All primitive in comparison. Or perhaps we can only see what's left . Leaving only what nature hasn't touched to see them. So nature is in a sense very good at rearrangement of our understanding. Therefore nothing is certain ..very human trait to see a delayed understanding of our world.

[@greghemlock6679]

Without the magnetic shield, it will kill 98% of all life on earth probably

[@Twotone-ld1fb]

I disagree, there have been many pole shifts in the past and none of them caused mass extinction events. Well, one which was a pole wobble that hit Australia pretty bad caused a couple species in Australia only to die off. The mass extinction events we know of were caused by other things like meteorite impacts.

[@muntee33]

Yes, the field had weakened by 10% in 1640... But it's not 1640 now and the field isnt weakening in a slow, linear manner. And he is WAAAY out with his 1500yr prediction. Not only is he off by a whole order of magnitude, the field doesn't weaken to 0 before 'reversing' Instead, there is a critical threshold beyond which the field 'weakens to zero' practically instantaneously as once it crosses the minimal threshold it 'collapses' And we're talking about a time scale to that threshold which is between our lifetime and our grandchildrens lifetime, with the probability of it being sooner rather than later.

[@REktSigMa]

13:12 I’m sure this is a dumb question but how do they know those rocks came from mars and know a meteor impact flung rocks into space that then made there way to earth🤯🤯. I’m sure they compared them to samples we took from mars and found they were pretty much identical but how do they know how they got to earth? I feel like some of the story is being withheld for our "safety"😂😂. I’m love learning about space and science but my smooth brain just can’t understand this lmao

[@Epic_C]

They're just making it up

[@SnappyWasHere]

Not a dumb question. But unless you’re an astrophysics you may not understand it. Science is so complex now and so specialized it really can’t be explained in simple words anymore. You can google the simple explanation and we’ve known they came from Mars for decades. This is a core issue with science now, it’s hard for us common people to understand.

[@reb2322]

@@SnappyWasHerenot a dumb question! They don't know themselves but they need employment so they fabricate something.........but they can't prove it. Their computer simulations are foolish, as they input information based on theory and speculation and the computer spits out whatever they fed it, only in a more complex and convincing form so it appears to be scientifically proven. Dumb in.....dumb out! LLL

[@jkelley9335]

Easy answer. Aliens landed on Mars and the alien kids collected rocks like we collect eggs on Easter. Then they stopped at the moon and did the same.then they land on earth and spread them out for earthlings to find.they like to troll us idiots

[@mansoormannix1753]

Yes Solar storm might cause a very big damage to most of our electric and electronic technology not to mention radiation damage. But we still have last line of defense though, our atmosphere.

[@muntee33]

The current state of things is apparently pointing to a magnetic excursion instead of a full reversal. (Where the poles destabilize and migrate towards the equator, before restabilising and reestablishing themselves in their prior orientation.) While not as profound for life on Earth as a full reversal it is not an ideal situation nonetheless. Nothing to worry about tho, worrying wont stop it, nor will carbon credits.

@@woodrowtaylor6907 This technique is not reliable. It's like with this dinosaur they once found. One part of his skeleton was estimated to be 40,000 years old, and another 100,000 using carbon dating. It was the same skeleton by the way.

[@picklepopsickle]

@@sansebastiansj Its still worth using, they make sure that the date is consistent throughout the skeleton before drawing any conclusions. A heavy fish diet can skew the results, so there are samples that are more reliable than others.

We need more volcanism! Never thought i would cheer on catastrophic plate tectonics. More motion means MAYBE more magnetism. Our next 200 generations will be fine according to this model, so let's keep on as usual, but still try to get to that 4th level civilization. It's going to take quantum and a space-time physics revolution to make interstellar travel and wormholes a possibility.

Is this prediction of the field's disappearance based on physics, without the intervention of chemistry's support of magnetism. Like Einstein was not a chemist, but this only means physics got separated from chemistry's study to separate the math studies from the chemistry studies to get both well know as a skill. Chemistry is magnetism's support for its existence!

[@rayjasmantas9609]

In other words, using physics alone could alter the Earth responses, as the pollution dumping causing global warming. The calculation support would possibly not be complete one way or another. {In other words why is chemistry matter losing its magnetism.}

[@rayjasmantas9609]

Note to: Physics invents cable TV's transmission, but chemistry develops the copper's use.

Also chemistry works out balances to stay in tack, but physics is more based on reaching projections, right?
