"It might happen in some of our lifetimes"
Oh no we're all gonna die!!!!
"But it won't kill us so don't panic."
Oh ok whew
"It will probably affect the power sources and communication."
I NEED WI

Wait pigeons use magnetic fields to navigate? Wow, I have more respect for pigeons than humans now.

Also guess what, Earth's magnetic poles are swapping right now. So guess what we got to look forward to this century.

If the magnetic field reverses an my internet connection gets cut off I'm gonna be so fucking pissed

[jeffhobbs]

video idea:what would happen if the moon crashed into earth

[rastko]

What happend to Play Noggin?
Is that channel dead for sure?

[mikk]

listen I don't want to hear about the sun's coronial mass ejections

[rickybravo]

Why can't earth just pick a side already 😭 you know I can't live without wifi 😭

[Kermialdo]

Shit!
If the magnetic field is reversed I am going to die because there is going to be no wi-fi.

Last time I was this early, YouTube wasn't fucked up

[augustflorian]

so you are saying that earth's magnetic field changed 260 times since the dinosaurs died? if my math is correct

[versysbc]

So if Earth's magnetic field is weakening at 5% per decade, and say in about 30-40 years we were to get hit by a CME the size of the Carrington Event of 1859, not narrowly avoiding it like we did in July 2012, what exactly could be the effects of that?

Hi Life Noggin,

thank you for your great science videos! Could you make a video about geomagnet excursions? I mean it is related to this video. There are very few videos on YT about this amazing topic!

A geomagnetic excursion can happen in 7 years.

And the south pole has already left antarctica

Je n'ai pas pour habitude de regarder des vidéos en anglais et encore moins de les commentée, mais là je me sens obligé, juste bravo à toi et/ou a vous (bc je ne sais pas si vous êtes plusieurs ^^) pour cette vidéo, le sujet est intéressant, c'est éducatif et tous ça sur fond d'animation vraiment cool, +1 like

[kusaluprety]

So every terrible thing (San Andreas, magnetic pole reversal, etc.) is overdue

[doyoungiverse]

I'M STILL CONFUSED.


BUT I STILL WANT TO THANK YOU FOR MAKING THIS VIDEO.

[atomicdragon]

I was very suprised to see this video in my science quiz, love ya

[MrEsel]

you cant just say it changes ever 200k-300k but it hasnt changed in the last 780k years. how am i supposed to sleep now without knowing it?!
if you think im joking, sadly im not :D

[lpenrike]

i love how you said "when" instead of "if"

[athxna]

I always look forward to life noggin videos
