- Time travel is the concept of movement (often by a human) between different points in time in a manner analogous to moving between different points in space, typically using a hypothetical device known as a time machine.on-technological forms of time travel had appeared in a number of earlier stories such as Charles Dickens ' A Christmas Carol. Historically, the concept dates back to the early mythologies of Hinduism (such as the Mahabharata).

Einstein's Theory of General Relativity Einstein's theory of general relativity predicted that the space-time around Earth would be not only warped but also twisted by the planet's rotation. Gravity Probe B showed this to be correct.Credit: NASA View full size image.In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity.instein's theory of general relativity predicted that the space-time around Earth would be not only warped but also twisted by the planet's rotation.

Time Two contrasting viewpoints on time divide many prominent philosophers. One view is that time is part of the fundamental structure of the universe —a dimension independent of events, in which events occur in sequence.Sir Isaac Newton subscribed to this realist view, and hence it is sometimes referred to as Newtonian time.ime travel is the concept of moving backwards or forwards to different points in time, in a manner analogous to moving through space, and different from the normal flow of time to an earthbound observer. In this view, all points in time (including future times) persist in some way.

What are the scientific theories of how how the world was created? There are several different theories, the most popular by far being the Big Bang theory. This name refers to the idea that the world was created by a primordial hot and dense initial condition at some finite time in the past, and continues to expand to this day. Another is the Creation theory, in which everything in the world was created by God.

- There are actually two theories of relativity. The earlier theory is known as the special theory of relativity or special relativity and the later theory is known as general relativity. The general theory is an expansion of the special theory to include what are called non inertial reference frames.

The Big Question: Is time travel possible, and is there any chance that it will ever take place? If travelling back in time is possible at all, it should in theory be only possible to travel back to the point when the first time machine was created and so this would mean that time travellers from the future would be able to visit us.

Einstein's Theory of Relativity Space-time. In his general theory of relativity, Einstein views gravity not as a force but as a curvature of the fabric of space in the presence of a massive object like a black hole (see Topic 2, Chapter 1 of this unit).According to Einstein, the fabric of space is a four-dimensional space representing the universe.his chapter looks at Einstein's special and general theories of relativity. It also explains related terms like 'time-space', 'gravity' and 'gravitation'.

- One pertains to relative mass, length, time in a frame of reference which is in motion with respect to other which is at rest mass. According to this theory called theory of special relativity, mass, time, length are not absolute but are relative according to their frame of regency which are in relative motion. Mass in s frame of reference moving with respect to other reference increases, time decreases or dilates and length increases.

Time travel Time travel in physics. Some theories, most notably special and general relativity, suggest that suitable geometries of spacetime or specific types of motion in space might allow time travel into the past and future if these geometries or motions were possible.

theory of relativity According to the theory of general relativity, matter causes space to curve. It is posited that gravitation is not a force, as understood by Newtonian physics, but a curved field (an area of space under the influence of a force) in the space-time continuum that is actually created by the presence of mass.

- In the standard models, there is a preferred foliation of. space-time into space-like hypersurfaces (in most cases, the foliation is unique). 2. Time in this preferred foliation is called cosmic time. 3. Meaning: Cosmic time is the proper time of the. fundamental observers, which move with the cosmic fluid.

Space-time In non-relativistic classical mechanics, the use of Euclidean space instead of space-time is good, because time is treated as universal with a constant rate of passage which is independent of the state of motion of an observer.

Time Travel Theory Time Travel Theory. Time travel is a concept that has most likely existed ever since man has realized his own mistakes and wished he could change them. Philosophers, physicists and authors popularized it. There are several theories that suggest time travel is possible. There are also basic human activities that prove time travel is possible. However, time travel as it occurs in fiction and time travel that actually moves you backward in time is simply out of our reach, thus far.

What is the fundamental reason of the speed of light being constant in all frames of reference? Historically, of course, we redefined space and time because the theory of relativity, and its empirical confirmation, suggested that it would be more parsimonious to take the speed of light as a fixed constant for all observers, by definition, and define length in terms of the speed of light and the definition of time.

- Land Bridge Theory Synopsis: The Land Bridge Theory, also known as the Bering Strait Theory or Beringia Theory, is a popular model of migration into the New World. This theory was first proposed in 1590 by Jose josé De acosta and has been widely accepted since the. 1930sThe Land Bridge theory proposes that people migrated From siberia To alaska across a land bridge that spanned the current Day Bering. straithe Land Bridge Theory proposes that people migrated from Siberia to Alaska across a land bridge that spanned the current day Bering Strait. The first people to populate the Americas were believed to have migrated across the Bering Land Bridge while tracking large game animal herds.

Time Travel Theory There are several theories that suggest time travel is possible. There are also basic human activities that prove time travel is possible. However, time travel as it occurs in fiction and time travel that actually moves you backward in time is simply out of our reach, thus far.here are a few ways that we know time travel is possible, though they are very basic and are only perceptive or based on our definition of time zones. For example, a person on an aircraft is traveling forward in time because of the speed of the craft.
