The concept of Multiverse


Are We Living in a Multiverse? Why We 

Might – and Why We Might Never Know

The concept of a multiverse, or multiple universes, has long been a topic of fascination for scientists and science fiction writers alike. It is a fascinating idea that suggests that our universe is not the only one that exists, but rather, there are many parallel universes out there, each with its own unique set of physical laws and properties.

The idea of a multiverse has been around for centuries, but it was only in the last few decades that it has gained widespread acceptance in the scientific community. The concept is rooted in the theory of quantum mechanics, which suggests that particles can exist in multiple states or locations at the same time.

One of the most popular interpretations of the multiverse theory is the "many-worlds" interpretation, which was proposed by physicist Hugh Everett in the 1950s. This interpretation suggests that every time a quantum measurement is made, the universe splits into multiple parallel universes, each one containing a different outcome of the measurement.




Another popular version of the multiverse theory is the "bubble universe" hypothesis, which suggests that our universe is just one of many "bubbles" that exist in a larger multiverse. Each bubble universe would have its own unique set of physical laws and properties, making them completely different from one another.     


The idea of a multiverse raises some intriguing questions about the nature of our reality and our place in the cosmos.
For example, if there are multiple versions of ourselves in different parallel universes, do we have free will, or are our actions predetermined by the laws of physics? And if there are other universes out there, could we ever find a way to travel between them and explore their mysteries?

While the concept of a multiverse is still largely theoretical, it is an area of research that is gaining more attention from scientists and researchers around the world. By studying the nature of quantum mechanics and the properties of the universe as a whole, we may one day be able to unlock the secrets of the multiverse and discover new realms of reality that we never thought possible.


We may never be able to rigorously test specific multiverse theories, for the predictions derived from them simply have too many “moving parts.” Observers in different sub-universes of the overall multiverse will in general see very different physical laws. If we assume that a multiverse theory predicts what a “typical” observer in the multiverse measures, the results will depend on how we model observers and count them. 

Unfortunately, there is so much freedom here that almost arbitrary “predictions” can be derived.

Nature is a teacher – What happens when you allow everything to be “as it is”?

Nature is a teacher – What happens when you allow everything to be “as it is”?   A number of years ago I went on holiday to a beautiful part of Portugal. We stayed in a converted farmhouse in the middle of a national park. The farmhouse was in a valley. We arrived in the evening when the birds were just starting to roost. It was still warm and the air smelled sweet with pollen. You could hear the hum of crickets. A small river flowed through that valley. We opened a rickety gate and crossed a small wooden bridge. As we walked along the narrow path that led to our house I had a clear vision of what my morning routine would be like for the next fourteen days. I had been working hard for the last few months and I felt tired. I wanted this holiday to be a mini retreat. I would wake up early each day when it was still quite cool and I would meditate for a while. I imagined myself sitting in a peaceful spot, my mind calm, my body relaxed… listening to the river flowing, hearing the birds...
