Hey guys, I've been wondering about this for a few months I guess; the only answers I get when I search google are metaphysical and vague, so I'm hoping you can give me some better understanding of this phenomenon.

Hold your hands a few inches apart from each other, then pretend there's an invisible ball and slowly roll it around between your two palms. Alternatively, slowly bring your hands back forth from each other. Eventually you'll start to feel something that I can only describe as magnetic repulsion between the two hands.

If someone could tell me why this happens I'd be grateful.

Dumping infopics in return I guess.

There are magnets in your hands or something.

Tried it. Didn't feel anything..

[Anonymous No.1988258]

C'mon guys, rational explanation please.

[Anonymous No.1988273]

We can't explain it...

.. it must be God.

Have verified that multiple people have experienced a similar sensation when I showed them, so I'm operating under the assumption that I am not batshit crazy. Might take a few minutes to get the movements right if it's your first try.

Douchebag, I'm not making any such implications; I genuinely want to know the science behind this.

[Anonymous No.1988282]

[Anonymous No.1988283]

It's called Chi. It's not scientifically understood. Attempts to study it have been thus far unsuccessful.

[Anonymous No.1988285]

Man, all of my science infopics suck. Gonna just freestyle.

You're a faggot, I don't want this answer.

[Anonymous No.1988289]

Yeah, was my first attempt. Not sure if I did it right either.

It was a joke, mate. Relax.

OP, after viewing your pic I now find snowflakes to be creepy.

[Anonymous No.1988318]

>>1988204
That's interesting, OP. I did the ball trick, and the resulting force opposes both shear and compression.

So I suspect something like this: Initially, the control is a conscious effort (for lack of a better expression). You need to think about what you're doing, and imagine you're feeling that the ball is there. After some moments, a less conscious portion of your brain sorts out what you're doing, and begins to take over the effort of controlling the motion. Your conscious brain now interprets this as a kind of actual resistance.

I may be explaining poorly, but it's like any practiced physical motion, I suppose. When you begin to type or play the piano, every motion is considered. After some practice, though, those motions are managed in a less conscious fashion.

Anon, I think this has something to do with torques. If you don't know what a torque is, then it might not mean much to you but let me try to explain it in an easy way.

Torque is the force applied over some distance that causes rotation, as in, a door where you apply a force at the very edge and the door rotates on its hinges. Arms also experience torques due to the fact that they are elongated and bounded by hinges (the joints). My thought is that when you are moving your hands in either direction at some continuous cycle (right-left or right up etc) as described in your post, what eventually you end up doing is having to counteract the original torque present in one direction while trying to go to the opposite direction (i.e. the original motion up has to apply an opposite torque down to change the direction). Keep doing this and what you end up feeling as if there are forces opposing your movement (reversing torque direction) and consequently as if your hands were magically attractive repulsive!

Another example is a long stick (say a broom stick without the broom part). If you hold it right at the middle (assuming it's uniform) you'll only feel its weight and say, "oh, it's not too heavy", but now if you grab it at one end and swing it, then trying to swing it back at the other direcion, suddenly the stick feels however. This is again due to torques and similarly I imagine that this situation applies in your case OP.

Do the stick experiment, honest.

Hope this helps.

I was understandably skeptical about this but I definitely felt something very very noticeable. I think it might have something to do with your muscles settling in a certain position, sort of like when you squeeze something for a minute and then hold your fingers in a closed position for another minute and it feels like you can't open your hand.

[Anonymous No.1988436]

>>1988431
if you have ever gripped something too hard your hand can lock to where you have to squeeze harder to unlock, kind of like a parking brake, dont know why, you just reminded me of this

[Anonymous No.1988464]

The only problem I have with this explanation is that it doesn't seem to account for the pressure I feel on my opposite hand if I only move one hand.

[Anonymous No.1988496]

>>1988464

Are you sure? I can't feel anything when I keep one hand static and when I do, is because I notice my whole body moves a little along with my arm which again exerts a torque (albeit small). Try to mantain your arm AND body static while moving your left hand, but make sure you do it properly, then tell me if you still feel it. I honestly don't.

[Anonymous No.1988531]

>>1988496
Yeah, I'm pretty sure I do. Can you feel the sensation described if you don't initiate it with both hands? Try it with just one and see if you can generate the torque, I haven't been able to yet.

Hey OP, you've discovered chi
I'm a martial artist, I study and practice Kung Fu, real Kung Fu.
what you're doing is part of a meditation.

For anyone that never believed in chi, OP has found it.

The trick is, though, learning to harness that energy and use it.

Feels good man.

OP here. I respect your opinions, but unless you can validate them with scientific process I don't think they belong in this thread.

Yes, as I said, I feel something if my torso moves a little as my other arm moves, otherwise I don't. On the other hand, right now I'm not the best experimental witness because I already unconsciously expect to feel nothing, so I may be suppressing it.

I would like to hear what others besides OP feel if they just move on hand. Any help but doing it with the precautions stated here >>1988496
