If a wormhole could exist, it would appear as a spherical opening to an otherwise distant part of the cosmos. In this doctored photograph of Times
Square, the wormhole allows New Yorkers to walk to the Sahara with a single step, rather than spending hours on the plane to Tamanrasset.
Wormhole – Description
In physics, a wormhole, also known as an Einstein-Rosen bridge (and less commonly as an Einstein-Rosen-Podolsky bridge or Einstein-Podolsky-Rosen bridge), is a hypothetical topological feature of spacetime that is essentially a "shortcut" through space and time. A wormhole has at least two mouths which are connected to a single throat. Matter can 'travel' from one mouth to the other by passing through the throat.

wanted to, a new quantum model has stated.
Waves of light ordinarily have a positive or zero energy density at different points in space (top). But in a so-called squeezed state, the energy density at a particular instant in time can become negative at some locations (bottom). To compensate, the peak positive density must increase.

The warp field creates a bubble that has the effect of reducing the local gravitational constant, the factor relating force to mass and distance in Newton’s law of gravitation. It is universal and only more recent investigation suggests possible alteration with time. The constant approximates to 6.670 x 10-11 Nm2 Kg-2. The field coils in the nacelles must create a balanced field, thus they must operate in union. In practice the general form is to have two (or multiples thereof) engines mounted parallel to the axis of desired movement but offset from the line of the ship's center of mass.

Time Travel
Time Travel – Possible?
Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light speed, you could travel thousands of years into the Earth's future.
• Philadelphia Experiment reconstruction. In the fall of 1943 a U.S. Navy destroyer was made invisible and teleported from Philadelphia, Pennsylvania, to Norfolk, Virginia, in an incident known as the Philadelphia Experiment. The ship involved in the experiment was supposedly the USS Eldridge.

Quantum Realities and Parallel Universes
The many-worlds interpretation is DeWitt's rendering of the relative state formalism (and interpretation). Everett referred to the system (such as an observer) as being split by an observation, each split corresponding to a possible outcome of an observation. These splits generate a possible tree as shown in the graphic below. Subsequently DeWitt introduced the term "world" to describe a complete measurement history of an observer, which corresponds roughly to a path starting at the root of that tree. Note that "splitting" in this sense, is hardly new or even quantum mechanical.

Quantum field theory corrects several limitations of ordinary quantum mechanics, which we will briefly discuss. The Schrödinger equation, in its most commonly encountered form, is
where denotes the quantum state of a particle with mass m, in the presence of a potential V.
