As I announced in a message following the publication of the March 1, 2025 session, I'm creating this thread to raise potential questions about quantum physics that could be put to the Cs at future sessions, in order to participate, at our humble level, in the International Year of Quantum Science and Quantum Technologies.
Today, we'll be talking about electrons which have the peculiarity of all being identical.
The observable universe contains an unimaginable number of electrons. Yet a daring theory put forward by physicist John Wheeler suggests that all these electrons are, in fact, one and the same, traveling through time. A fascinating idea that has intrigued scientists for decades.
The estimated number of electrons in the universe is staggering: 10⁸² (a figure made up of 82 zeros). Yet Wheeler came up with a radically different explanation. Rather than seeing these particles as independent, he posited that all these electrons would in fact be one and the same electron, moving backwards and forwards in time, creating the illusion of a multitude of electrons.
What makes this hypothesis intriguing is that all electrons are strictly identical. Whatever their origin, their charge, mass and spin are always exactly the same. This perfect uniformity is one of the greatest mysteries of quantum physics. For Wheeler, this observation was the key to his reasoning : if all electrons are absolutely indistinguishable, then why not consider that they are in fact the same ?
If this idea is true, it would mean that positrons (the antiparticles of electrons) are just that same electron returning from the future. In other words, every time an electron seems to go back in time, it appears as a positron, an identical particle but with an opposite charge. This idea had a profound influence on Feynman who used the concept in his own work on the interpretation of antiparticles.
One of the main problems with Wheeler's hypothesis is that we observe far more electrons than positrons in the universe. If this theory is correct, there should be as many positrons as electrons, which is not what we observe. Wheeler tried to explain this anomaly by supposing that the “missing” positrons could be hidden in protons but this idea was never supported by scientific evidence.
The idea of a single electron traversing time is a fine intellectual curiosity but it doesn't seem to fit in with modern observations of the universe. Nevertheless, it illustrates the strangeness of the quantum world where classical concepts of time and distinct particles become blurred. What if, one day, a theory more global than quantum theory were to overturn everything we know ?
This raises the following questions :
- Does Wheeler's idea conform to reality?
- Is time travel one of the keys to the next physics whereas current physics is essentially based on displacement in space?
- Why do scientists observe more electrons than positrons in 3D (Cs have told us that, in 4D, we are aware that there is exactly as much matter as antimatter, which would give us here as many electrons as positrons)? So, would what deprives us of this perception (as many electrons as positrons) be, in 3D, the absence of awareness of the nature of the 4th “dimension” of space?
- If so, would the 4th “dimension” of space, that very special frequency, be perception or the present moment? I'd lean towards the present moment, which allows us to take into account all the times in the universe, positive and negative, at the same time, thus naturally echoing Wheeler's intuition of a journey through time.

Comme je l'ai annoncé, en message, suite à la publication de la session du 1er mars 2025, je crée ce fil afin de faire émerger de potentielles questions sur la physique quantique qui pourraient être posées aux Cs lors des prochaines sessions afin de participer, à notre humble niveau, à l'année internationale de la Science quantique et des technologies quantiques.
Aujourd'hui, il sera question des électrons qui présentent la particularité d'être tous identiques.
L’univers observable contient un nombre inimaginable d’électrons. Pourtant, une théorie audacieuse avancée par le physicien John Wheeler suggère que tous ces électrons ne seraient, en réalité, qu’un seul et même électron voyageant à travers le temps. Une idée fascinante qui intrigue les scientifiques depuis des décennies.
L’estimation du nombre d’électrons dans l’univers est vertigineuse : 10⁸² (soit un chiffre composé de 82 zéros). Pourtant, Wheeler a imaginé une explication radicalement différente. Plutôt que de considérer ces particules comme indépendantes, il a avancé que tous ces électrons ne seraient en fait qu’un seul et même électron, se déplaçant en avant et en arrière dans le temps, créant ainsi l’illusion d’une multitude d’électrons.
Ce qui rend cette hypothèse intrigante, c’est que tous les électrons sont strictement identiques. Quelle que soit leur origine, leur charge, masse et spin sont toujours exactement les mêmes. Cette uniformité parfaite est l’un des plus grands mystères de la physique quantique. Pour Wheeler, ce constat était la clé de son raisonnement : si tous les électrons sont absolument indiscernables alors pourquoi ne pas envisager qu’ils sont en réalité le même ?
Si cette idée est vraie, elle signifierait que les positrons (les antiparticules des électrons) ne sont que ce même électron revenant du futur. En d’autres termes, à chaque fois qu’un électron semble remonter le temps, il apparaît sous forme de positron, une particule identique mais avec une charge opposée. Cette idée a profondément influencé Feynman qui a repris ce concept pour ses propres travaux sur l’interprétation des antiparticules.
L’un des principaux problèmes de l’hypothèse de Wheeler vient du fait que nous observons bien plus d’électrons que de positrons dans l’univers. Si cette théorie est correcte, il devrait y avoir autant de positrons que d’électrons, ce qui n’est pas ce que nous observons. Wheeler tenta d’expliquer cette anomalie en supposant que les positrons « manquants » pourraient être cachés dans les protons mais cette idée n’a jamais été étayée par des preuves scientifiques.
L’idée d’un unique électron traversant le temps est une belle curiosité intellectuelle mais elle ne correspond pas apparemment aux observations modernes de l’univers. Toutefois, elle illustre l’étrangeté du monde quantique où les concepts classiques de temps et de particules distinctes deviennent flous. Et si un jour une théorie plus globale que la théorie quantique venait bouleverser tout ce que nous savons ?
Ainsi, nous sommes en droit de nous poser les questions suivantes :
- Est-ce que l'idée de Wheeler est conforme à la réalité ?
- Est-ce qu'une des clés de la prochaine physique est le voyage dans le temps alors que la physique actuelle ne se base essentiellement que sur des déplacements dans l'espace ?
- Pourquoi les scientifiques observent-ils plus d'électrons que de positrons en 3D (les Cs nous ont dit qu'en 4D, nous sommes conscients qu'il y a exactement autant de matière que d'antimatière, ce qui nous donnerait ici autant d'électrons que de positrons) ? Alors, est-ce que ce qui nous prive de cette perception (autant d'électrons que de positrons) serait, en 3D, l'absence de conscience de la nature de la 4ème "dimension" de l'espace ?
- Dans l'affirmative, la 4ème "dimension" de l'espace, cette fréquence si particulière, serait-elle la perception ou l'instant présent ? Je pencherais pour l'instant présent qui permet de prendre en compte tous les temps de l'univers, positifs et négatifs, en même temps, rejoignant ainsi naturellement l'intuition de Wheeler d'un voyage à travers le temps.
