time machines

As a variation on the rotating cylinder, some scientists have suggested using “cosmic strings” to construct a time machine. At the moment, these are purely theoretical objects that might possibly be left over from the creation of the universe in the Big Bang. A black hole contains a one-dimensional singularity – an infinitely small point in the space-time continuum.
A cosmic string, if such a thing existed, would be a two-dimensional singularity – an infinitely thin line that has even stranger effects on the fabric of space and time. Although no one has actually found a cosmic string, astronomers have suggested that they may explain strange effects seen in distant galaxies.
By maneuvering two cosmic strings close together – or possibly just one string plus a black hole – it is theoretically possible to create a whole array of “closed timelike curves.” Your best bet is to fire two infinitely long cosmic strings past each other at very high speeds, then fly your ship around them in a carefully calculated figure eight. In theory, you would be able to emerge anywhere, anytime!

Important time travel dates

1895
British author H.G. Wells publishes “The Time Machine.”
1905
Albert Einstein’s special theory of relativity shows that space and time are relative, not absolute, and that time is actually a fourth dimension within what he calls “space-time.”
1916
Einstein discovers that space-time is curved.
1937
Mathematician Kurt Goedel proposes that the universe itself may be a time machine.
1949
Goedel demonstrates mathematically that pathways through time are possible.
1967
U.S. physicist John Wheeler invents the name “black hole” to describe singularities in space and time.
1974
Astrophysicist Frank Tipler plots paths around a vast, imaginary spinning cylinder, confirming that paths through time can exist.
1987
Air Force scientist and engineer David Anderson proposes his time-warped field theory.
1988
Caltech University’s Kip Thorne suggests using wormholes as a possible means of time travel.
1990
David Anderson extends time-warped field theory creating the worlds’ first complete space-time model and virtual laboratory.

Richard Gott at Princeton University proves that cosmic strings could be used for time travel.
1995
The Time Travel Research Center is formed by David Anderson.

quantum mechanics Early History

EARLY HISTORY
In the 18th and 19th centuries, Newtonian, or classical, mechanics appeared to provide a wholly accurate description of the motions of bodies—for example, planetary motion. In the late 19th and early 20th centuries, however, experimental findings raised doubts about the completeness of Newtonian theory. Among the newer observations were the lines that appear in the spectra of light emitted by heated gases, or gases in which electric discharges take place. From the model of the atom developed in the early 20th century by the English physicist Ernest Rutherford, in which negatively charged electrons circle a positive nucleus in orbits prescribed by Newton’s laws of motion, scientists had also expected that the electrons would emit light over a broad frequency range, rather than in the narrow frequency ranges that form the lines in a spectrum.
Another puzzle for physicists was the coexistence of two theories of light: the corpuscular theory, which explains light as a stream of particles, and the wave theory, which views light as electromagnetic waves. A third problem was the absence of a molecular basis for thermodynamics. In his book Elementary Principles in Statistical Mechanics (1902), the American mathematical physicist J. Willard Gibbs conceded the impossibility of framing a theory of molecular action that reconciled thermodynamics, radiation, and electrical phenomena as they were then understood.

Causality

Causality, in philosophy, relationship of a cause to its effect. The Greek philosopher Aristotle enumerated four different kinds of causes: the material, the formal, the efficient, and the final. The material cause is what anything is made of—for example, brass or marble is the material cause of a given statue. The formal cause is the form, type, or pattern according to which anything is made; thus, the style of architecture would be the formal cause of a house. The efficient cause is the immediate power acting to produce the work, such as the manual energy of the laborers. The final cause is the end or motive for the sake of which the work is produced—that is, the pleasure of the owner. The principles that Aristotle outlined formed the basis of the modern scientific concept that specific stimuli will produce standard results under controlled conditions. Other Greek philosophers, particularly the 2nd century skeptic Sextus Empiricus, attacked the principles of causality
