Do we live in a parallel universe? Here is Why We May Be Living in a Parallel World

The idea of our civilization living in a parallel Universe has remained a science fiction shown in movies for years. But many known renowned scientists like Stephen Hawking believed that our universe may be one out of many universes with similar features to each other. Hawking even coined a multiverse theory to explain his idea even better. Based on the spectacular theories about the multiverse, can we boldly say that the parallel universe exists? When was the idea of a multiverse invented? Can we look beyond our universe to discover the multiverse? Continue reading to find out.

What is a Multiverse?

The multiverse exists as a hypothetical set of multiple universes that are made up of space, time, energy, matter, and other physical laws that have remained known and unknown to human civilization. Scientists suggest that different universes exist within the multiverse, and these universes are also identified as parallel universes or alternative universes.

When was the idea of the Multiverse invented?

For centuries, the idea of the multiverse has remained unknown to humans. In fact, ancient scientists even believed that the Earth was at the center of the Universe, while the sun and other celestial bodies revolve around it. After Galileo Galilee made his astronomical discoveries in 1610, a new era of astronomy was born. However, Galilee and other astronomers thought that the Milky Way was the end of the Universe.

This idea remained valid until the 20th century when Astronomer Edwin Hubble discovered that our home galaxy is just one out of billions of galaxies that made up the Universe. Hence, another Era of astronomy was created with Hubble’s discovery in the 1920s. Before then, American Philosopher William James had already coined the term, multiverse in 1895. James used this term to describe a confusing moral meaning of natural phenomena, implying that he was not referring to the existence of other possible universes at that time.

In the 1950s, Hugh Everett introduced the concept of the multiverse and changed the way we think about space. But how did Hugh Everett come up with this idea? One Evening in 1954, when Everett was having a good time with his friends at Princeton University, he suddenly developed the idea of quantum effects constantly causing the Universe to split. He later advanced this idea for his Ph.D. thesis.

The graduate student held up a theory that we are living in a multiverse containing countless universes, occupied by copies of each living being on Earth. Scientists were fascinated by this theory as they read meaning into Everett’s concept of the Multiverse. This new theory made scientists wonder if we are truly living in a multiverse. In fact, it gave rise to new debate as many renowned scientists are sharing different opinions about the concepts of the Multiverse.

Are we truly living in the Multiverse?

 After Hugh Everett developed the concept of the Multiverse, astronomers began to look at the Cosmos from a different perspective. Astrophysicist Stephen Hawking was one of the renowned scientists that develop a special interest in the Multiverse theory. Hawking was so fascinated with the idea that he collaborated with Professor Thomas Hertog from KU Leuven to publish his final theory about the origin of the Universe. This publication was made in the journal of high Energy Physics in 2018. The theory was developed based on string theory. It specifically predicts that the universe is less complex as described by several big bang theories. Hawking concluded the theory with this bold statement.

“We are not down to a single, unique universe, but our findings imply a significant reduction of the multiverse, to a much smaller range of possible universes.”

Aside from Hawking, many physicists also believed in the Multiverse theories. Their opinions could be traced to the big bang theory. According to the big bang theory, our universe was an infinitesimal singularity around 13.7 billion years ago, until it burst out and inflate faster than light speed across all directions. This theory further stated that after the universe exploded outwards, the cosmic inflation traveled for some time before slowing down to create atoms, molecules, planets, stars, and galaxies.

The strange mysteries surrounding the birth of our universe made some scientists suggest the possible existence of multiple universes. A renowned scientist Alexander Vilenkin, theoretical physicist of Tufts Universe in Massachusetts speculated that cosmic inflation of the early universe did not actually stop anywhere at exactly the same time. This suggests that cosmic inflation continues expanding to other distant worlds.

Vilenkin later named his concept the theory of eternal inflation and published it in Scientific American in 2011. He concluded by stating that when cosmic inflation stops at any destination, it will create a new bubble universe, before progressing to another place. However, each bubble universe will not reach another as they all constantly expanding indefinitely. This theory holds stronger proof of the existence of the multi-universe.

Do we live in a parallel universe?

Based on the existing theories about the possibilities of a parallel universe, you may begin to wonder if we truly live in a parallel universe. However, we are yet to find evidence to prove the existence of multiple universes outside our universe. Based on our current level of technology, we cannot look beyond our observable universe to see what lies outside the vast space. However, we cannot doubt the technological might of the future generation, as they may invent technologies to discover if we are living in a parallel universe or just one universe.


The existence of the parallel universe has remained science fiction for decades. However, scientists are beginning to see the possibilities of us living in a parallel world. Although we are yet to find evidence of multiple universes, we are still optimistic that future generation will use their futuristic technologies to answer this question. What do you think about parallel universes and their existence?
