Parallel universe: Does it exist?


Parallel universe: Does it exist?

One might be in love with the idea of a parallel universe, which is basically a parallel dimension or an alternate universe. Maybe it's appealing because one gets second chances, and things might turn out differently. An alternate reality where one might actually get into Hogwarts or Napolean wins the Battle of Waterloo or the British Empire holds on to its American colony or where you were never born.

For over a hundred years, science has been haunted by a dark secret: that there might be mysterious hidden worlds beyond our human senses. Collection of an infinite number of such parallel universes constitute a “multiverse”.

But is there really such a place in science for such wistful speculations. I mean if the universe is everything in itself, then we actually cannot have an identical copy of it right? Then the concept of the universe altogether would have been a lie. The problem here lies with the terminology. When the physicists mean “universe”, they mean the observable universe that is a part of the whole, which so far, we have been able to see. And it is perfectly fine to talk about multiple different observable universes. For instance, an alien at the edge of our observable universe will see parts of the whole universe that we cannot see because the light might not have reached us yet!!

There have been theories to support the idea of the existence of a multiverse. Three mathematical models have been proposed as per a 2012 Space.com article.
          1.     Bubble universes or baby black hole universes.
          2.     Membranes and extra dimensions.
          3.     The many-worlds picture of quantum mechanics.

Science says that humans cannot dream, they just haven’t learnt how to control their teleporting powers when they are unconscious, which is why they can’t fully remember what happened when they wake up. Each dream is actually a parallel universe.
Mystics had long claimed of places full of ghosts and spirits. Well, the last thing science wanted was to be associated with superstitions, but ever since the 1920s, physicists have been trying to make sense of an uncomfortable discovery. When they tried to pinpoint the exact location of atomic particles, like electrons, they found it to be utterly impossible. They had no single location and this is one of the major reasons why science becomes more and more interested in the possible outcomes of parallel worlds. The only explanation one can give is that particles don’t just exist in one universe. They exist in other universes too and there can be infinite such universes, each slightly different from the others.

A parallel world might contain a copy of ourselves. The life of this person has been identical to us in all respects maybe. Still having subtle differences. Perhaps your copy might be deciding to put down the article unfinished, while you continue reading it. Our timelines are similar but not identical because we co-exist in alternate realities.

As Carl Sagan said “Imagination will often carry us to worlds that never were. But without it we go nowhere”. Who knows, perhaps, some of our most special dreams are a window into a parallel universe. The idea might be very fascinating, but we must always remember, physics is science and not philosophy. So we can only make claims that are tested.

Hence as a conclusion, the multiverse theory is obviously just a theory. The existence of parallel universes has not been proven and the subject remains a widely debatable one among physicists.

  1. You have said that the exact location of electron is not known but how does this imply that there is existence of a parallel universe.
    Also, it has been mentioned that the dreams are a window to the parallel universe. But isn't it is true that dreams are basically the visuals that our subconscious mind shows us, and they do relate to the various incidents that occur throughout the day.

    1. Thank you for your question
      Well for the first question : exact location of electrons has not yet been detected can give us a subtle hint that particles might exist in not one universe , but in many other such universes simultaneously, this might pinpoint towards existence of a parallel universe .
      And as per your second question : dreams do actually have a connection with the reality as per research . It might happen that you dream of a place which later you find out to exist in real world , but previously , you had no clue about such a place . Sometimes , people dream of certain events or maybe a certain group of people whom they have never met previously , but later those events may turn out to be a reality. This has happened to a lot .You can say that , this is a mere chance of coincidence , but actually this can even reflect on the existence of a ''you'' in an alternate universe .
      But definitely these points have not been proven yet , and hence we lack strong evidence towards existence of a parallel universe .
      Thank you

  2. You should clarify your facts. First of all, I'm sure you have read about Heisenberg's Uncertainty Principle. I think you should have mentioned that one cannot perceive momentum and location of an electron simultaneously. What we can perceive is a cloud around which electrons are presumed to be present. The blog makes it seem that electrons are running around all. Then neither we could have had any successful bombardment or fission or fusion today.

  3. Thank you for your feedback . I would surely try clarifying facts as much as I can in my future articles.

  4. Your article on parallel universes is intriguing and thought-provoking. However, I believe there's room for clarification on a few points. For instance, regarding the uncertainty of an electron's location, it's important to mention Heisenberg's Uncertainty Principle, which states that the exact position and momentum of an electron cannot be simultaneously known. This doesn't imply parallel universes but rather reflects the limitations in our measurements.

    Also, while it's fascinating to consider that dreams might be glimpses into parallel universes, the current scientific consensus suggests that dreams are more likely the result of our brain processing daily experiences and subconscious thoughts.

    Overall, your exploration of these concepts is engaging, and I appreciate the effort to connect theoretical physics with everyday phenomena.

The God Particle

                      'The God particle' also known as Higgs boson particle was discovered in 2013, with the help of the Hadron collider. It was said to be “the missing cornerstone of particle physics” by the CERN director.         Many disputes have been over why this is named so. Basically this particle gives an explanation of the origin of the universe.  It is a physical proof of an invisible, universe wide field which gave mass to all particles after the Big Bang.         This field better known as the “Higg's field” is different from all other fields as it is present everywhere even in vacuum. Now after providing mass it forced all particles to merge and form the stars, planets and led to the formation of the whole Milky Way galaxy.          So it was a very essential particle leading to the origin of the universe and gradually life as we know it.                 Now what is it's relation to time travel? The physi

HYPERLOOP

FIFTH MODE OF TRANSPORTATION-“HYPERLOOP” The concept of Hyperloop was first conceived in 2012 by renowned entrepreneur and founder of SpaceX and TESLA, Elon Musk . He was in search of a new, the fifth mode of transportation which can redefine the future of travelling by drastically reducing the travel time on land. It is termed hyperloop as it would go in a loop. Hyperloop is the greatest leap in mode of transportation infrastructure for generations. With passengers sitting in a pod and travelling through evacuated sealed metal tubes at a speed greater than that of an airline, the concept seems to be fictitious but it is on the verge of becoming reality. The speed of conventional mode of transportation i.e. buses, cars or trains is limited by air resistance and friction.   Hyperloop drastically reduces friction and air resistance by means of magnetic levitation, electric Propulsion and partially vacuum steel tubes. The concept is open-sourced by Elon Musk, the result of whi

NEUROIMAGING IN IDENTIFYING DISORDERS

NEUROIMAGING IN IDENTIFYING DISORDERS Neuroimaging deals with the in vivo applications of various techniques to illustrate and study the structural & functional characteristics of the nervous system. Neuroimaging can be classified into two categories: • Structural neuroimaging, which involves the imaging of the structure of the nervous system and the diagnosis of intracranial injuries and tumours. • Functional imaging, which involves the study and diagnosis of metabolic diseases and cognitive research. The most widely used techniques involved in the process of neuroimaging are: 1. Computed Tomography (CT) or Computed Axial Tomography (CAT), in which X-ray images of the brain from various directions are taken and presented as cross-sections of the brain. 2. Magnetic Resonance Imaging (MRI), which uses magnetic fields and radio waves to obtain high-resolution 2D or 3D images of the brain. 3. Positron Emission Tomography (PET), which measures emissions from radioac
