Contrary to what you might expect, Sliders is actually based on real science. Indeed, the idea of parallel worlds may seem on the face of it to be pure fantasy, but for many scientists, it is much more than mere science-fiction.
Einstein's theory of relativity predicted the existence of "black holes", a hypothesis which has since been verified. These cosmic phenomena arise from the death of a star, after it collapses in on itself under the force of its own gravity. Inside a black hole, gravity is so intense that even light cannot escape the gravitational field (hence the name black hole).
Albert Einstein and another physicist by the name of Nathan Rosen posited that each black hole would symmetrically on another gravitational well called a white hole (or sometimes also white fountain). The black hole/white hole pair would form a "wormhole", or vortex (the interdimensional passage used by the Sliders, called an Einstein-Rosen Bridge).
Thus, any matter swallowed up by the black hole would be quickly spat out by the white hole, in an unknown location... This could be either a distant point in the universe, in which case the wormhole would act as a shortcut through space and time. Alternatively, it could be a parallel universe, in which case it would act as a bridge between the different dimensions.
The second hypothesis could explain the total absense of antimatter in the universe as we know it. According to the universe's governing principle of symmetry, there must be equal amounts of matter and antimatter. However, we have failed to discover the slightest trace of the latter, although we have succeeded in producing it artificially (at the CERN laboratory in Geneva, Switzerland in 1995, and in other particle accelerators). The existence of parallel universes could explain the lack of antimatter in our world. In parallel dimensions, then, there could be objects similar to the planets and stars we are familiar with in our own, but constructed of antimatter (this is one of the most recent theories, after the principles of dissymetry, and of the annihilation frontier).
According to a poll of 72 leading physicists conducted by the American researcher David Raub in 1995 (published in the French periodical Sciences et Avenir in January 1998), the multiple universe theory is widely accepted:
58% of physicists (including Stephen Hawking) think multiple universes exist
18% (including Roger Penrose) do not accept this theory
13% admit the possibility, but remain unconvinced
and 11 % have no opinion.
Sadly, we are not yet able to cross these bridges, if they exist. In fact, it would require a tremendous amount of energy to open a wormhole artificially, and the gravitational force inside would be so strong that we would be completely crushed.
Thus, Quinn must be a true genius to be able to open an interdimensional vortex so easily and quickly, and without suffering any injury!
Those who believe time travel may be possible rely similarly on the existence of parallel universes, which would allow for the resolution of the "grandfather paradox":
If a man were to go back in time and kill his grandfather as a child, logically speaking he would not be born, since his father before him would not be born. But if he wasn't born, he can't go back and kill his grandfather, therefore his grandfather lives, and the grandson is eventually born, therefore he can kill his grandfather, and so on...
If you consider that wormholes are shortcuts through the space-time continuum, the man could use one to go kill his grandfather. However, he would arrive not in the past of his own universe, but instead in that of a parallel universe, in which his existence does not depend on the continued existence of his grandfather. In killing this version of his grandfather, he would simply be preventing the birth of his double in the parallel universe...

The parallel universe theory, first proposed in 1950 by US physicist Hugh Everett, helps explain mysteries of quantum mechanics that have baffled scientists for decades.
According to this theory, every time a new physical possibility is explored, the universe splits. Given a number of possible alternative outcomes, each one is played out in its own universe. A motorist who almost meets with an accident, for instance, might feel relieved at his lucky escape.
But in a parallel universe in another version, the same driver would have been killed. Yet another universe will see the motorist recover after treatment in hospital. The number of alternative scenarios is endless. Like an everyday universe, it is a region of space and time containing matter, galaxies, stars, planets and living beings. In other words, every time a new physical possibility is explored, the universe splits.
A parallel universe is similar, and possibly, even a duplicate of our own universe. There are human beings who may be exact duplicates of ourselves and who are connected to us through mechanisms only explainable using quantum physics concepts. Parallel universes are also called alternative universes, quantum universes, parallel worlds, alternative timelines, etc.
In order to visualize what are parallel universes, you have to be introduced to new scales and concepts. The Universe is basically 5 dimensions, and is unknown except to a select few of mankind! You are familiar with the first three axis of ordinary space, x, y, and z. The fourth is time. We have to setup a defined three-dimensional box, with defined distances, to explain the fifth dimension. The time progression, forward or reverse of matter and energy within the box is the fourth dimension. The fifth dimension involves vibrational frequency. This frequency is super imposed on matter and energy at the sub atomic level. This would be called its resonant frequency. The fifth dimension has many different levels. In these infinite levels, matter and energy exists in a natural state. What mankind does not know is that matter and energy, and that which is the essence of life, exists at different vibrational frequencies. Each vibrational level is independent from each other, but occupy the same space. Atoms of different frequencies do not mix; they simply slide past each other. To get a clearer picture, lets put part of the Universe in a finite 3 dimensional box, and observe what you would see, and what laws would apply. We would start at the base vibrational frequency for matter and energy. This would be our Universe and laws, represented by the name density level 3. Now a new formula and concept has to be introduced to help you understand. Density Constant = [Time (measured in progression)] * [speed of Light (C)]. Mankind is familiar with the density constant by another name, the cosmological constant. For all levels in the fifth dimension, the density constant is the same, but T and C vary in proportion. Meanwhile to an observer in any confined level in the fifth dimension, light will travel its new rate of speed per standard unit of time. Once outside the levels, variations occur in relation to each other. The progression of time is transparent to you, because you have no anchor points or comparisons. Now, lets increase the vibrational frequency governing some of the mass and energy until it completely transposes up to the next level of existence, density level 4. For an example, let heat equal the vibrational frequency of the atomic structure, and water molecules at 20 degrees F. equal mass and energy. Increase the heat, and some of the water molecules move from a solid to a liquid at a particular point, approximately 32 degrees F. The water molecules are still the same, but in a different form. The higher energy levels consist of lower mass density levels, and new laws of motion. Ice and liquid water can be in the same area, but the molecules do not mix. They slide past each other, creating an environment independent from each other. Also vibrational rates just like temperature can vary and still stay at a confined density level. Now the matter and energy in the box at density level 3 is still there, but you can’t see or interact with matter and energy at density level 4. At density level 4 a new Universe appears, less dense in the number of stars, and in the density of matter itself. What else has changed? Some stars will be in the same positions, but the luminosity may be different. There are stars in new locations, but quite are few missing. In fourth density, the density of the Universe is less in comparison to third, our level. Mankind thought that light is a constant, but in fourth density light has a velocity approximately 17 times faster than in third density. Time is progressively slower in fourth density than in third, but to an entity in third density it seems the same. When the frequency is moved density level 5 the velocity of light is squared from the speed in level 4. Time slows down in proportion. When light leaves a star in the Zeta Reticuli system, which is 38 light years away. It takes approximately 1.6 months for light to arrive at Earth in fifth density. All next levels repeat. What controls this? There is a subatomic particle, which is not known to most of mankind. This subatomic particle controls the resonant frequency of the atomic structure, where matter and energy exists. The more the subatomic particle increases in proportion to the affected mass, the resultant frequency becomes higher. Higher dimensions are created at certain frequency break points. Each level is a Quantum leap for differentials in time and the speed of light. You are now pondering to yourself, what does all this mean? Some potential applications are, traveling faster than the speed of light, making it possible to have surgery without breaking the skin, and the ability to transport matter to different locations instantly. The ability to pass through solid matter in 3rd density when in a transition phase move to or from 4th density, and the ability to manipulate the flow of time are some of the benefits for density shifting.
To perceive an abstract idea of time differentials that is between the densities, let time in the fourth density be represented by a sine wave completing one cycle with a wavelength of equal to the distance A. The amplitude of the sine wave will equal to a number represented by B, and the amplitude also corresponds to the vibrational rate of matter and energy in the fourth density. Both A and B are constants. Now I will compare a fourth density time sine wave form to a third density sine wave and observe the differences. In the third density, the time sine wave now completes 17 cycles in the same space governed by distance A. The amplitude of the waveform is .0588B or 1/17 its original height, and corresponds to a lower vibrational rate of matter and energy in the third density (Earth Plane). If you were to unravel both sine waves into a straight line, one cycle in fourth density and seventeen cycles in third density both would be equal. To the entities that live in each density, one cycle of the sine wave would equal one unit of perceived time. Therefore one day in fourth density is like seventeen days in third.
I want to thank God for bestowing knowledge
