New Theoritical Model Eliminates Barriers To Time Travel

"The machine is space time itself," Professor Amos Ori explains. "If
we were to create an area with a warp like this in space that would
enable time lines to close on themselves, it might enable future
generations to return to visit our time. We, however, could not return
to previous ages because our predecessors did not create this
infrastructure for us."

A Technion-Israel Institute of Technology physicist has developed a
theoretical model of a time machine that could enable future
generations to travel into the past. In his paper published in the
July issue of Physical Review, noted time-travel theorist Professor
Amos Ori provides practical solutions to a number of criteria long
seen by other experts as obstacles to the realization of time travel.

Ori's theory is actually a set of mathematical equations describing
hypothetical conditions that, if established, could lead to the
formation of a time machine, technically known as "closed time-like
curves."

Previous theories addressing time travel are well grounded in
Einstein's General Relativity theory. Renowned physicist Stephen
Hawking has called time travel "an important subject for research,"
but has also proposed some of the strongest challenges to the concept.
General Relativity states, among other things, that the gravitational
pull of large objects such as planets can actually bend time and
space. Time travel research is based on bending space-time so far that
the time lines actually bend back on themselves to form a loop.

"We know that bending does happen all the time, but we want the
bending to be strong enough and to take a special form where the lines
of time make closed loops," says Ori. "We are trying to find out if it
is possible to manipulate space-time to develop in such a way."

While the possibility of time travel has never been eliminated,
scientists have identified a number of physical challenges, including
the perceived need for some form of exotic matter with negative
density. Such matter is predicted by quantum field theory to exist,
though only in quantities too small for the construction of a time
machine.

In a 2004 paper, Ori outlined a set of conditions that would allow for
the creation of a time loop without the need for exotic matter. That
theory called for the time loop to form as a donut-shaped vacuum,
inside which time would curve back on itself, so that a person
traveling around the loop might be able to go further back in time
with each lap. A sphere containing non-exotic, but unidentified
matter, would in turn envelop the loop.

Ori's latest work eliminates the need for that unidentified matter.
His new calculations show that the envelope can in fact be filled with
dust, a simple modeling of which is used regularly in theoretical
physics, while still allowing for the evolution of a time machine.

Ori also addresses the possibility of the initial conditions forming a
point of infinite gravitational field that no one could pass (instead
of a time travel loop). His current paper outlines a more robust
system that would prevent such an occurrence. "The internal core is
now mathematically protected," says Ori, "and it is easy to show that
no irregularity could penetrate it." The paper also more thoroughly
defines the required spherical envelope.

Ori says serious questions remain about the overall stability of a
time machine. His own calculations - done in collaboration with
Technion Ph.D. student Dana Levanony - and those of other physicists,
suggest that the evolution of a time machine would be dependent on a
very narrow range of initial conditions that might be difficult - or
even impossible - to achieve. He is also working to show ways such a
configuration could be achieved.

"If the proper initial conditions were achieved, the time machine
would evolve on its own without any further intervention," says Ori,
of the Technion Faculty of Physics. "It can be likened to shooting a
ship with a cannon. Once the cannon is aimed properly and fired, the
cannonball hits the ship on its own, driven solely by the laws of
physics."

"The machine is space time itself," he explains. "If we were to create
an area with a warp like this in space that would enable time lines to
close on themselves, it might enable future generations to return to
visit our time. We, however, could not return to previous ages because
our predecessors did not create this infrastructure for us."

repeated stooopidity doesnt become wiser

they can easily take a copy of whatever created infrastructures back
in time,

so they can return from anywhere

The point is they couldn't go further back in time than the time at
which the first one became operational.

ahaha... I must remember to add Amos Ori to my growing list of time
travel crackpots. ahahaha... Ori's paper, of course, was accepted by
Physical Review, where peer review is synonymous with ass review.
ahahaha... AHAHAHA... ahahaha... A couple of days ago, that other time
travel crackpot, Ronald Mallet, was making a complete fool of himself
on Coast-to-Coast AM. When are those morons going to learn?

Time travel is an impossible thing!


Why?

It is crackpottery by Relativity Theory charlatans like Kaku and Hawkings
to sell their crap books to poor souls,
much like the "perpetuum mobile" and "free energy" stuff etc.

Why?

Too complicated for you to understand, goose.

But it has to do with interconnection of all things.

Unfortunately, every time you puke something up,
somewhere in the world, something dies. If I
go back and kill you at birth, then I have to
bring all those things back to life, and
it's just too much work.

Since I doubt your logical argument is based in mathematics beyond my
understanding, I'll go ahead and assume it is a philosophical argument
that I wouldn't be interested in understanding anyway.

Yep. I don't care.
