pattern, Young was the first to realize that light beaming through the two holes spreads out in overlapping waves.

      A modern variation of the experiment fires off single photons through the double slit. These single photons also produce zebra patterns on the screen, demonstrating that even single units of light travel as a smeared-out wave with a large sphere of influence.

      Twentieth-century physicists went on to use Young’s experiment with other individual quantum particles, and held it up as proof that quantum physics had Through-the-Looking-Glass properties: quantum entities acted wavelike and travelled though both slits at once. Fire a stream of electrons at the triple screens, and you end up with the interference patterns of alternating light and dark patches, just as you do with a beam of light. Since you need at least two waves to create such interference patterns, the implication of the experiment is that the photon is somehow mysteriously able to travel through both slits at the same time and interfere with itself when it reunites.

      The double-slit experiment encapsulates the central mystery of quantum physics – the idea that a subatomic particle is not a single seat but the entire stadium. It also demonstrates the principle that electrons, which exist in a hermetic quantum state, are ultimately unknowable. You could not identify something about a quantum entity without stopping the particle in its tracks, at which point it would collapse to a single point.

      In Zeilinger’s adaptation of the slit experiment, using molecules instead of subatomic particles, the interferometer contained an array of slits in the first screen, and a grating of identical parallel slits in the second one, whose purpose was to diffract (or deflect) the molecules passing by. The third grating, turned perpendicular to the beam of molecules, acted as a scanning ‘mask’, with the ability to calculate the size of the waves of any of the molecules passing through, by means of a highly sensitive laser detector to locate the positions of the molecules and their interference patterns.

      For the initial experiment, Zeilinger and his team carefully chose a batch of fullerene molecules, or ‘buckyballs’ made of 60 carbon atoms. At one nanometre apiece, these are the behemoths of the molecular world. They selected fullerene not only for its size but also for its neat arrangement, with a shape like a tiny symmetrical football.

      It was a delicate operation. Zeilinger’s group had to work with just the right temperature; heating the molecules just a hair too much would cause them to disintegrate. Zeilinger heated the fullerenes to 900 K so they would create an intense molecular beam, then fired them through the first screen; they then passed through the second screen before making a pattern on the final screen. The results were unequivocal. Each molecule displayed the ability to create interference patterns with itself. Some of the largest units of physical matter had not ‘localized’ into their final state. Like a subatomic particle, these giant molecules had not yet gelled into anything real.

      The Vienna team scouted out some other molecules that were double the size and oddly shaped to see if geometrically asymmetric molecules also demonstrated the same magical properties. They settled on gigantic fluorinated American football-shaped molecules of 70 carbon atoms and pancake-shaped tetraphenylporphyrin, a derivative of the biodye present in chlorophyll. At more than 100 atoms apiece, both of these entities are among the largest molecules on the planet. Again, each one created an interference pattern with itself.

      Sai Ghosh didn’t often think about the implications of her discovery. She was content with the knowledge that her experiment had made a very nice paper, and might help along her career as an assistant professor involved in research into miniaturization, the direction she believed quantum mechanics was heading. Occasionally, she allowed herself to speculate that her crystal might have proved something important about the nature of the universe. But she was only a postgraduate student. What did she, after all, really know about how the world worked?

      But to me, Ghosh’s research and Zeilinger’s work on the double-slit experiment represent two defining moments in modern physics. Ghosh’s experiments show that an invisible connection exists between the fundamental elements of matter, which is often so strong that it can override classical methods of influence, such as heat or a push. Zeilinger’s work demonstrated something even more astonishing. Large matter was neither something solid and stable nor something that necessarily behaved according to Newtonian rules. Molecules needed some other influence to settle them into a completed state of being.

      Theirs were the first evidence that the peculiar properties of quantum physics do not simply occur at the quantum level with subatomic particles, but also in the world of visible matter. Molecules also exist in a state of pure potential, not a final actuality. Under certain circumstances, they escape Newtonian rules of force and display quantum non-local effects. The fact that something as large as a molecule can become entangled suggests that there are not two rule books – the physics of the large and the physics of the small – but only a single rule book for all of life.

      These two experiments also hold the key to a science of intention – how thoughts are able to affect finished, solid matter. They suggest that the observer effect occurs not simply in the world of the quantum particle but also in the world of the everyday. Things no longer should be seen to exist in and of themselves but, like a quantum particle, only in relationship. Co-creation and influence may be a basic, inherent property of life. Our observation of every component in our world may help to determine its final state, which suggests that we are likely to be influencing every large thing we see around us. When we enter a crowded room, when we engage with our partners and our children, when we gaze up at the sky, we may be creating and even influencing at every moment. We can’t yet demonstrate this at normal temperatures; our equipment is still too crude. But we already have some preliminary proof: the physical world – matter itself – appears to be malleable, susceptible to influence from the outside.
