The end of the earth's magnetic field and plate tectonics in about a billion years is likely to make life rather uncomfortable well before the sun does, but that's a rather minor quibble about an otherwise fun video

i effin heart the magnetic fields!

I don't really understand how a pair of entangled electrons allows the bird to detect miniscule changes in the magnetic field, and if they are in superposition, ie they are both simultaneously spin up and spin down, then how does that effect the chemistry of these entangled proteins?

Also, I thought the reason entanglement doesn't break the whole "can't send information faster than the speed of light" was because you had no control over whether you see spin up or spin down, and therefore it was effectively impossible to send information faster than light. Doesn't this example of the robin seem to contradict this?

I did a little digging when I first watched this and all I could really find/understand was they introduced VERY little noise into the magnetic field, a disturbance so fine that the robin would be unable to detect it unless something was going on at the quantum level. Yet, the robin did evidently detect it and thats why these theories exist.

Anywai, its super interesting. good sift.

"Magnetic field ... with empty space between the tread and alloy wheel."

What!?! Because that wouldn't be excessively heavy/expensive/dangerous at all, oh no. I can't decide whether this should be in commercial, scifi, or parody.

Humans are evolved to be social animals. I think they are also evolved to be religious animals. It doesn't make any of it true, and it doesn't matter what religion it is. It makes sense: hundreds of thousands of years of evolution and belief in magic, witch doctors, animal spirits, priests, gods and angels, - all of which binding the rules of the social group, rejecting or killing those who don't believe... is bound to reinforce some biological traits. It's even proven that these traits can be artificially triggered through strong magnetic fields or even drugs.
So... a diet of religion is good for you... has a biochemical effect creating a sense of well-being and belonging.
@shinyblurry 's personal relationship God is no different than that of a Hindu, Buddist, Tao or Mormon... i'm sure it feels good.
I think people get too obsessed with being intolerant of religion just to hurt others and feel superior. But it's like telling a child there's no santa or magic... why ruin something nice just because facts get in the way?
Reality is all subjective. If you like your's please enjoy but keep it to yourself.


It makes sense from an evolutionary standpoint, but another standpoint is that we were all created to worship. Even people who do not subscribe to any particular belief have something in their lives that they pay homage to, be it money, power, celebrity, their hobbies, or even themselves.

I also appreciate your sentiment about trying to be superior but I think your point is somewhat undermined when you contrast disputing with people who are religious to taking candy away from children who don't understand what facts are.

@zombieater - earth has a strong magnetic field compared to mars, it helps us to hold on to our atmosphere.. it's not very obvious, dunno why it wasn't mentioned.

This is most likely the most AMAZING filament eruption to be caught on video. It is caused by a little process called magnetic reconnection. It's a little process that gives us our solar flares, these filaments, CMEs (Coronal Mass Ejections), auroras, and the possible potential for very dangerous radiation storms every few millennium--give or take a few. Basically, plasma flows along these field lines of magnetism. When things get out of hand, then those field lines distort and change and all of a sudden things get very dangerous (AND sometimes beautiful). The faster the magnetic field changes the faster the particles will travel making them more and more dangerous as the events unfold fast enough giving them more energy (kinetic & heat), which in turn if directed at us means it penetrates much further into our protective field and anything outside of the field, crispy--in the shredded DNA, cells, you name it sense.

Occasionally, Earth's magnetic field breaks down a bit (if I remember why correctly it was a certain "sequence" within our magnetic shield and it reacts badly with the Sun's--don't quote me though, I really need to look it back up again it was a very long time ago I remember this from), if a large solar flare directed towards Earth ever happened before Earth had enough time to fully build back it's strength we would be FAR more in trouble than usual, but this would be a rare event. Usually what happens is that the charged particles follow Earth's magnetic lines and go to the poles, which is the one place on Earth where you do suffer the most radiation from the Sun (basically wherever the poles are as the plasma follows the polarity or "field lines" of Earth's magnetic field). It's also why the closer you are to the poles the better your view is of the aurora as the particles streaming in, if there is a sufficient quantity moving very fast (the more energy, especially kinetic--speed, the farther the penetration into the atmosphere and the lower the aurora becomes visible), will enter the atmosphere and begin to be absorbed by various elements that our atmosphere is compromised of like Nitrogen.

Here's a quick explanation. Basically, the particles collide with atoms of molecules/elements or anything in the higher atmosphere, exciting their electrons into higher energy levels, which is known fundamentally in science as quantum leap/atomic transition/electron transition it's one of the atom's most fundamental abilities dealing with "extra energy" being pushed into a system that wants balance (this is a very common process that happens ALL DAY long, EVERYWHERE around you; it transfers photons essentially--pure energy--BUT, what is the energy in the form of as it's energy level makes it do very many different things; you could see things, what you consider the normal range of light--it's EXACTLY how light goes THROUGH a window--it doesn't go through the window it is transferred via the atoms from one side to the next, this is ALSO why people are trying to get invisibility to work as it just might; HEAT is another one that is transferred all the time--it literally radiates outwards from our bodies and then we are surrounded by excited electrons and the infrared range of light we are putting out, the heat of a human body...or any animal; this goes on and on, it happens everywhere and as I said ALL-THE-TIME, it's perhaps one of the most critical processes and abilities of the atom and how photons also transfer their energy between areas in a direction; a little off-topic information for those that don't realize how much is going on, everywhere, all the time, at any given second...it's a complicated, but beautiful world)), and making them give off light that we see when the charge they've taken on finally returns the molecule/element's electrons to their normal orbits in the electron shell; the color depends on what molecule/element was being bombarded and how much energy was involved from the particle that hit it). This of course transfers all the energy that those particles had and we get a nice light show.

/I thought I'd fill my promote with something useful; ...on why these happen...
//edit-For a little more clarity, grammar and a bit more information that I hope some will appreciate if it helps anyone learn something or atleast go look up some of this and learn some on their own; taking an interest in science, it's one of the most important things in the world that we have.
///Spreading science is just as important; it's the one literal thing we do/use that has ever allowed us to deal with the worst problems we have: fear, pain, death, disease, sorrow, despair, ignorance, etc... Science IS the light in the dark. It is our best hope for mankind's continued existence and a good life. It is the single most important activity we now do as a group; it's our savior from us and what's out there...

The best thing you can do with magnets:
Step 1: take a cassette tape and expose tape to different magnetic fields
Step 2: ???
Step 3: Dubstep

I have a question. What does the flashing colours actually mean??

I don't know either, so I did some googling. http://psychcentral.com/lib/2007/types-of-brain-imaging-techniques/ Thats as close as I came to answering the question. If the CAT scan tag is accurate then I've no idea how they image brain activity, so I'd guess it was of the other methods or a combination. Basically blood flow/oxygenation, electrical or magnetic fields from brain activity or positrons produced from radioactive decay from active parts of the brain.

What any of that means in terms of what is actually going on in the brain I've no idea. Ask a neurologist

If you note the channel audio to the left, that indicates that it is purely an audio submission.
