In the last science article, we have understood the concept of the Mars Rover. In this article, we will learn the concept of the One-Electron Universe Theory.

## One-Electron Universe:

It is the hypothesis that all electrons and positrons are manifestations of a single entity moving backwards and forwards in time. In simple terms, according to this theory, there is only one electron that moves backwards and forward in time.

By moving and interacting with the past and the future, the electron bounces itself in the past and future. It interacts with itself an infinite number of times and produces an infinite number of electrons.

The basic idea of the one-electron theory is that every single electron in the universe is the one same electron travelling forwards and backwards in time. The idea is a bit crazy! One the other hand, the approach was revolutionary for the time.

Let us understand the history behind this idea.

## History:

In the Spring of 1940, one of the famous physicist, John Wheeler called his favourite student Richard P Feynman. Wheeler said that all the electrons have the same charge and mass because they all are the same electron.

Wheeler got this idea because all the electrons have the same charge and identical mass. So he anticipated that all the electrons are a single electron.

The same electron moves back and forth in time and interacts with itself an infinite number of times. By interacting with itself, it produces an infinite number of electrons.

According to this theory, when an electron moves backwards in time, its a positron. Which is an antimatter particle of an electron.

**Positron: **A positron is the opposite of an electron. It has a positive electric charge.

Mathematically the one-electron universe theory has a very significant impact on many quantum mechanics calculations. But it failed to answer the question, if this theory is right, why there is very less antimatter found in the universe compared to normal matter.

Let us understand a few of the applications of the one-electron theory.

## Applications:

- This theory was very helpful in getting many calculations of quantum mechanics.
- One-Electron universe if the first theoretical basis of time travel.

In conclusion, the one-electron theory might not be successful in experiments. But the premise of this helped us solve a lot of physics problems. This theory is also the basis of the recent Christopher Nolan’s masterpiece “Tenet.”
