If two things are kept completely isolated from each other, they cannot influence one another, right? The world's smartest scientists are actually saying they can. We're going to do a little magic trick with these two: Alice and Bob.

They both get one half of a deck of cards. Alice takes the red cards, starts shuffling them, and gets on a plane. Bob stays behind, shuffling the black cards. On the other side of the planet—after an extra shuffle for good measure—

Alice finally looks at the red card that's on top of her deck. What if I told you that the same black card is guaranteed to be on top of Bob's deck, despite the two of them having no contact whatsoever?

Good trick, right? In fact, it isn't a trick. It's not magic, it's quantum mechanics. Science has shown that is what actually happens with the tiniest pieces of matter. If two material particles—say, A and B—are shot in opposite directions—

what one scientist chooses to measure about particle A instantaneously influences what the other sees when he observes particle B. Even if the particles are at opposite ends of the universe. Imagine that: simply looking at something at one end of the universe can directly influence something at 

the other end, with no material connection between the two. Scientists have taken every precaution you can imagine to rule out communication between the scientists or the particles A and B. No cheating! And yet the observation of one influenced the results of the other.

This prediction of quantum mechanics existed for decades. Many physicists, Albert Einstein included, had
their doubts about this wild theory. But a series of compelling experiments, starting all the
way back in the 1970s, has shown it to be true.

So what does that mean?
Recently we have reached an incredible conclusion: What we call the physical or material world has no standalone existence. Instead, it is just a superficial image... ...in the mind of an observer - of a deeper, mysterious reality.

As such, matter only comes into existence upon being observed.
It's not really there, until you look. Yeah, try to get your head around that one. Not only our science, but also our culture and
civilization at large, stand to be fundamentally changed by...

...this realization in the years to come. Perhaps this sounds farfetched. But you can find out for yourself. You just have to look first.

이 동영상은 두 장의 분리된 카드 덱을 비유하여 양자 얽힘의 개념을 소개합니다.

앨리스와 밥은 각각 카드 한 덱의 절반씩을 받아 서로 다른 위치에서 따로 섞습니다.

이 비유는 앨리스의 덱의 맨 위 카드가 밥의 덱의 맨 위 카드에 해당하지만, 둘 사이에 아무런 통신이 없음을 보여줍니다.

양자 얽힘에 대한 설명 및 실험적 증거

이 비유는 한 입자를 측정하면 거리에 관계없이 다른 입자에 즉각적으로 영향을 미치는 양자 입자의 거동을 통해 설명할 수 있습니다.

이 현상은 입자 사이에 물질적 연결이 없는 것으로 설명됩니다.

실험을 통해 입자 또는 관찰자 간의 통신을 배제하고 그 효과를 확인했습니다.

처음에는 아인슈타인과 같은 과학자들도 의심했던 이 예측은 1970년대부터 실험적으로 검증되었습니다.

양자 얽힘이 현실에 대한 우리의 이해에 미치는 영향

이 영상은 물리적 세계가 독립적으로 존재하는 것이 아니라 관찰자의 마음속에 있는 피상적인 이미지라는 결론을 내립니다.

물질은 관찰을 통해서만 존재하게 됩니다.

이 발견은 과학, 문화, 문명에 중대한 영향을 미칩니다.
