"How to Build a Time Machine. It wouldn't be easy, but it might be
possible. By Paul Davies"

"For decades, time travel lay beyond the fringe of respectable
science. In recent years, however, the topic has become something of a
cottage industry among theoretical physicists."

"Our best understanding of time comes from Einstein's theories of
relativity. Prior to these theories, time was widely regarded as
absolute and universal, the same for everyone no matter what their
physical circumstances were. In his special theory of relativity,
Einstein proposed that the measured interval between two events
depends on how the observer is moving. Crucially, two observers who
move differently will experience different durations between the same
two events."

"So travel into the future is a proved fact, even if it has so far
been in rather unexciting amounts."

"Clocks run a bit faster in the attic than in the basement, which is
closer to the center of Earth and therefore deeper down in a
gravitational field."

"At the surface of a neutron star, gravity is so strong that time is
slowed by about 30 percent relative to Earth time. Viewed from such a
star, events here would resemble a fast-forwarded video. A black hole
represents the ultimate time warp; at the surface of the hole, time
stands still relative to Earth."

"In science fiction, wormholes are sometimes called stargates; they
offer a shortcut between two widely separated points in space. Jump
through a hypothetical wormhole, and you might come out moments later
on the other side of the galaxy. Wormholes naturally fit into the
general theory of relativity, whereby gravity warps not only time but
also space."

"The wormhole was used as a fictional device by Carl Sagan in his 1985
novel Contact. Prompted by Sagan, Kip S. Thorne and his co-workers at
the California Institute of Technology set out to find whether
wormholes were consistent with known physics."

"Assuming that the engineering problems could be overcome, the
production of a time machine could open up a Pandora's box of causal
paradoxes. Consider, for example, the time traveler who visits the
past and murders his mother when she was a young girl. How do we make
sense of this? If the girl dies, she cannot become the time traveler's
mother. But if the time traveler was never born, he could not go back
and murder his mother."

"Suppose the time traveler goes back and rescues a young girl from
murder, and this girl grows up to become his mother. The causal loop
is now self-consistent and no longer paradoxical."

"Consider the time traveler who leaps ahead a year and reads about a
new mathematical theorem in a future edition of Scientific American.
He notes the details, returns to his own time and teaches the theorem
to a student, who then writes it up for Scientific American. The
article is, of course, the very one that the time traveler read. The
question then arises: Where did the information about the theorem come
from?"

"The bizarre consequences of time travel have led some scientists to
reject the notion outright. Stephen W. Hawking of the University of
Cambridge has proposed a "chronology protection conjecture," which
would outlaw causal loops. Because the theory of relativity is known
to permit causal loops, chronology protection would require some other
factor to intercede to prevent travel into the past. What might this
factor be? One suggestion is that quantum processes will come to the
rescue."

"Chronology protection is still just a conjecture, so time travel
remains a possibility. A final resolution of the matter may have to
await the successful union of quantum mechanics and gravitation,
perhaps through a theory such as string theory or its extension, so-
called M-theory. It is even conceivable that the next generation of
particle accelerators will be able to create subatomic wormholes that
survive long enough for nearby particles to execute fleeting causal
loops. This would be a far cry from Wells's vision of a time machine,
but it would forever change our picture of physical reality."

Causality can't be broken.

If you were able to leap back in time, you'd find "forces", or events
would stop you from being able to break causality.

"Things" would just happen around you to stop you. You might try to
kill your own grandmother, but... somehow events would change that you
were never able to. Perhaps the local sherif would round you up, or
perhaps she'd be out that night, or perhaps she'd kill you instead
(which wouldn't break causality!!), or another thing would happen.

Basiscally, the laws of physics would stop you from breaking
causality.

The same thing goes for reading something you wrote yourself.
Something would stop you.

Or perhaps, you'd read it, then get struck on the head and forget it
all, setting you back so many years that in fact it takes you LONGER
to write the original article than had you not tried cheating
causality

Sad case .. you keep posting nonsense and replying to yourself.

The problems is that no such laws are known to act that way. One would
rather say 'the laws of logic' but this, of course, would not fit.

Perhaps it's simpler. If you travel to the past, you can change
nothing in it because you have already been in that past doing exactly
the same things you will do again.

This view poses at least one peculiar difficulty for time travel: your
body would simply disappear from the present and would not appear in
any past time in which it was nor already.

Most important, this alternative does not avoid cicularity in
causation although it avoids contradiction.

Regards

Ya don't have to be on their staff to see that both
"Scientific American" and "Nature" let the circulation
department have the last word on what gets in print.

For the past 15 years I've been cross checking their
articles for accuracy aginst the "Sun" and "Mirror".

Except for a few issues surrounding Princess Diana's
death the correlation is remarkable! :-)

Causality is a law of Nature just as inertia is.

Newton's 1st law contain the caveat
"unless it is compelled to change that state by forces impressed thereon"
and the forces impressed causes Every body not to persevere in its state of
rest, or deviate from its uniform motion in a right line.

Causality is the Zeroth law.

Time travel is nonsensical therefore it is not respectable science.
Respectable science is the ability to deal with observables.

The age of reason is being replaced by the age of commonsense. All
those left behind, are rightly so. For the most part, most people I
speak to still think the world is flat.

If you go faster than the speed of light you will exit the solar
system faster than light does. Simple. It takes 8 minutes for light to
reach the earth from the sun. At the speed of light it takes about 20
minutes to be outside of the solar system.

If you place an object faster than the speed of light into orbit
around the earth then the force of gravity wont be able keep that
object in orbit. That is unless Einsteins aether really exists, in
which case you can use a rudder, like on a boat ! LMAO.

Your watching too much Superman people.

One scenario.
If the observer succeeded in doing this, he wont be an observer of
anything while in motion. The light will compress at the retina. If he
slowed down he would be in the same place as he started orbiting
around the earth (of which was still orbiting around the sun) and the
dates and times would still be the same back home.

Light does not create time. Light enables us to see the clock. We
don't see anything other than light.

Other Scenario.
In the case that the object gained extraordinary mass by virtue of its
speed, the object would circle into the earth and cause an impact
disaster.

Other scenario.
In the case that the object gained extraordinary mass by virtue of its
speed, but was able to maintain its distance from the earths center of
mass it would cause permanent and irreversible 'time' damage to earth.
All those on Earth may survive this event, but would see day a night
in a very different cycle from then on.

Why ?

Universal law of gravity.

The force of gravity of that object would affect the orbit of earth.
You could return home and retire as pariah, since most of the
survivors will probably lynch you, and cast you in epoxy resin as a
monument never to mess with earths orbit. This would be a new 'age'
indeed, (not time travel) where everyone else would still remember who
you are, including the family who yo left behind for this experiment.
I believe this event is mentioned in the bible as the end of times.
Maybe then you will take a little guy 'Y' as a more serious warning.
'Oh yeah, that message a placed several distances ago'.
