For those who may not quite be aware, the multiverse is the set of possible universes including our own. While this may not be proven, it is a theory that continues to gain steadfast support from the world of physics.
These universes together make up everything that exists as a whole. We are thought to be a mere fragment of this multitude of universes. There have even been studies carried out on this subject. For instance, a study carried out not too long ago suggested that we may have a parallel ‘bubble universe.’
The video at the end of this article really helped me to better understand the multiverse theory and everything that comes along with it. Dr. Michio Kaku a theoretical physicist, as well as professor and best selling author, says that there are most likely parallel universes right in front of us. He claims “there are vibrations of different universes right here, right now. We’re just not in tune with them. There are probably other parallel universes in our living room – this is modern physics. This is the modern interpretation of quantum theory, that many worlds represent reality.”
Nobel prize winner Professor Steven Weinberg even supports the idea of a multiverse. He believes there is an infinite number of parallel realities coexisting with us in the very room we are in at this moment. There are quite a few theories on how to explain the behavior of quantum particles. One known as the Many World’s Interpretation actually suggests that at any given moment in time there is an infinite number of possibilities occurring and that all of them already exist and are happening simultaneously.
Kaku says as follows on his website:
When I was a child, I used to visit the Japanese Tea Garden in San Francisco. I would spend hours fascinated by the carp, who lived in a very shallow pond just inches beneath the lily pads, just beneath my fingers, totally oblivious to the universe above them.
I would ask myself a question only a child could ask: what would it be like to be a carp? What a strange world it would be! I imagined that the pond would be an entire universe, one that is two-dimensional in space. The carp would only be able to swim forwards and backward, and left and right. But I imagined that the concept of “up”, beyond the lily pads, would be totally alien to them. Any carp scientist daring to talk about “hyperspace”, i.e. the third dimension “above” the pond, would immediately be labeled a crank. I wondered what would happen if I could reach down and grab a carp scientist and lift it up into hyperspace. I thought what a wondrous story the scientist would tell the others! The carp would babble on about unbelievable new laws of physics: beings who could move without fins. Beings who could breathe without gills. Beings who could emit sounds without bubbles. I then wondered: how would a carp scientist know about our existence? One day it rained, and I saw the raindrops forming gentle ripples on the surface of the pond.
Then I understood.
The carp could see rippling shadows on the surface of the pond. The third dimension would be invisible to them, but vibrations in the third dimensions would be clearly visible. These ripples might even be felt by the carp, who would invent a silly concept to describe this, called “force.” They might even give these “forces” cute names, such as light and gravity. We would laugh at them, because, of course, we know there is no “force” at all, just the rippling of the water.
Today, many physicists believe that we are the carp swimming in our tiny pond, blissfully unaware of invisible, unseen universes hovering just above us in hyperspace. We spend our life in three spatial dimensions, confident that what we can see with our telescopes is all there is, ignorant of the possibility of 10-dimensional hyperspace. Although these higher dimensions are invisible, their “ripples” can clearly be seen and felt. We call these ripples gravity and light. The theory of hyperspace, however, languished for many decades for lack of any physical proof or application. But the theory once considered the province of eccentrics and mystics, is being revived for a simple reason: it may hold the key to the greatest theory of all time, the “theory of everything.”
Einstein spent the last 30 years of his life futilely chasing after this theory, the Holy Grail of physics. He wanted a theory that could explain the four fundamental forces that govern the universe: gravity, electromagnetism, and the two nuclear forces (weak and strong). It was supposed to be the crowning achievement of the last 2,000 years of science, ever since the Greeks asked what the world was made of. He was searching for an equation, perhaps no more than one-inch long, that could be placed on a T-shirt, but was so powerful it could explain everything from the Big Bang, exploding stars, to atoms and molecules, to the lilies of the field.
He wanted to read the mind of God. Ultimately, Einstein failed in his mission. In fact, he was shunned by many of his younger compatriots, who would taunt him with the ditty, “What God has torn asunder, no man can put together.” But perhaps Einstein is now having his revenge. For the past decade, there has been furious research on merging the four fundamental forces into a single theory, especially one that can meld general relativity (which explains gravity) with the quantum theory (which can explain the two nuclear forces and electromagnetism).
The problem is that relativity and the quantum theory are precise opposites. General relativity is a theory of the very large: galaxies, quasars, black holes, and even the Big Bang. It is based on bending the beautiful four-dimensional fabric of space and time. The quantum theory, by contrast, is a theory of the very small, i.e. the world of sub-atomic particles. It is based on discrete, tiny packets of energy called quanta. Over the past 50 years, many attempts have been tried to unite these polar opposites, and have failed. The road to the Unified Field Theory, the Theory of Everything, is littered with the corpses of failed attempts. The key to the puzzle may be hyperspace. In 1915, when Einstein said space-time was four-dimensional and was warped and rippled, he showed that this bending produced a “force” called gravity. In 1921, Theodor Kaluza wrote that ripples of the fifth dimension could be viewed as light. Like the fish seeing the ripples in hyperspace moving in their world, many physicists believe that light is created by ripples in five-dimensional space-time.
But what about dimensions higher than 5?
As you can he is is quite the deep thinker. When I came across his video on the multiverse theory I felt drawn to his works.
