Science stems from human curiosity. ‘Why and how do objects (such as an apple) fall?’ is a question that has been answered for three and a half centuries, yet it continues to be quoted and repeated everywhere. In contrast, however, we shall look at other important questions that modern science does not know the answer to. Or worse still, that it ignores.The Nobel Prize in Medicine (2026) has just been awarded to three researchers who have developed a technique known as ‘optogenetics’. Yet nobody seems to care to find out why synapses, which have existed in chordates for hundreds of millions of years, also respond to external signals received via a modern LASER. Surprising, isn't it? Furthermore, when it comes to synapses, discovered over 100 years ago, neurologists are still unable to determine exactly how and why they function of their own. What is more, the responses lies in the common solution to two other questions of the utmost importance.0) The aforementioned functioning of synapses, I emphasise, a mechanism that has been sought but remained a mystery for more than 100 years, which is resolved in [1].1) The process of consciousness-raising, one of the 25 major questions science has yet to resolve, and more specifically its delay and the difficulty in its emergence, which is resolved in [2].2) To something even more profound and equally unknown: the ‘miraculous’ hatching of language in children, language being the indispensable foundation of human socialisation and culture, which is addressed in [1].Three phenomena that share an unexpected common explanation: associated virtual information. And which, also explains why optogenetics can exist. An explanation which, if known, would in turn facilitate the improvement of this technology, which currently advances through trial and error, precisely because the reason for its feasibility remains unknown.A fourfold explanation (3 +1 =4) that will require the reader to read only the four pages that follow. But, this is based on two articles [1] and [2], which provide a detailed explanation of three significant issues: synapses, the development of consciousness-raising, and the miraculous emergence of language in children. Furthermore, the fact that all of this can be addressed in just around 150 pages is as striking as the unexpected discovery of a single, unifying solution, for all these questions ("Ockham’s Razor" principle).All of this is possible if the importance and power of the underlying information are recognized and accepted, rather than continuing to be ignored. It requires looking beyond merely the material aspects or the perceptible effects governed by this information. In these four cases, what lies beneath are the symbolic systems of symbolic support, characteristic of psychic information.Today, the importance of information is beyond question; it already enables us to simulate absolutely anything. Yet science still overlooks it as an ultimate and omnipresent cause. There is no trick to it: information and its virtual nature are the ‘wild card’ for all sciences. Without it, nothing would be possible. Nor nothing would it be comprehensible to humankind. We must not delude ourselves into thinking that information is a human discovery; we have merely incorporated it, recycling, what has always existed.
