The Multiverse ep 2

HISTORY OF MULTIVERSE CONCEPT 

Firstly if you don't read the episode one of the multiverse then please go and read it.

The concept of a multiverse has been a topic of scientific and philosophical discussion for centuries. It is a theory that suggests the existence of multiple universes or parallel realities, each with its own unique set of physical laws, particles, and dimensions. The idea of a multiverse has fascinated scientists and philosophers alike, but it is only in recent decades that we have begun to explore the possibility of its existence through empirical evidence and theoretical models. In this blog, we will explore the history of the multiverse concept and its evolution over time.

The earliest known mention of the multiverse concept can be traced back to ancient Indian mythology. The Hindu religion describes the concept of the "many worlds" theory, where the universe is described as infinite and eternal, with an infinite number of worlds coexisting simultaneously. The ancient Greeks also pondered the concept of multiple universes, with the philosopher Democritus postulating the existence of an infinite number of worlds. The idea of parallel universes was also discussed by the Chinese philosopher Zhuangzi, who wrote about a butterfly dream where he questioned whether he was a man dreaming he was a butterfly or a butterfly dreaming he was a man.

The concept of a multiverse also appears in various forms in literature and fiction. In the 19th century, French writer Jules Verne wrote about a journey to the center of the Earth, where the protagonists encounter a vast subterranean ocean that leads to a parallel world. Similarly, the concept of a parallel universe was explored in H.G. Wells' 1895 novel "The Time Machine," where the protagonist travels into the distant future and discovers two distinct races of humans living in parallel realities.

The modern scientific concept of a multiverse can be traced back to the 1950s and 1960s, where the notion of a "many worlds" interpretation of quantum mechanics was proposed by physicist Hugh Everett III. This interpretation suggests that every possible outcome of a quantum event occurs, each in a different universe. This theory was initially met with skepticism and criticism, but it laid the groundwork for the development of other multiverse theories in later years.

In the 1980s, physicist Andrei Linde proposed the concept of "eternal inflation," which suggests that the universe is continually expanding and generating new universes through a process of rapid inflation. This theory also proposed the idea of a "landscape" of universes, each with its own unique physical constants and properties.

Another significant contribution to the multiverse concept was made in the 1990s by physicist Max Tegmark, who proposed the idea of a "level one" multiverse. This theory suggests that the universe is infinite and that there are an infinite number of identical copies of our observable universe, each existing at an unimaginably large distance from one another.

In the early 2000s, cosmologist Brian Greene proposed the concept of a "brane" multiverse, which suggests that our universe is just one of many "membranes" floating in a higher-dimensional space. This theory also suggests that the fundamental particles of our universe are confined to our brane, which explains why we do not observe the effects of other universes.

In recent years, the concept of a multiverse has gained popularity among scientists and has become a topic of significant research. The discovery of the cosmic microwave background radiation and the development of sophisticated telescopes and instruments have allowed scientists to study the universe's structure and properties in greater detail.

One of the most significant pieces of evidence for the multiverse concept comes from observations of the cosmic microwave background radiation, which is thought to be the residual heat left over from the Big Bang. This radiation is incredibly uniform in temperature, suggesting that the universe underwent a period of rapid expansion known as inflation. Inflationary cosmology suggests that this expansion
