this is really neat ! ..but if you can go to "other" places ? ... maybe the "critters" on the t'other side.. how shall we say aren't very "friendly" than Oops lol but hey fuck it ! it always works out in the movies ..no ? lol

Time Travel: move over Michael J. Fox, real time travel may soon become reality

At a UCLA workshop attended by yours truly and other future watchers,
the late physicist Dr. Robert Forward told the group that further
understanding of the cosmos would one day enable man to travel through
time. “Given the money and mandate,” Forward said, “in the
not-too-distant future, a time machine will be built.” This workshop
convened in 1983; now, 31 years later, scientists are edging ever closer
towards realizing this bold prediction.
The
concept of time travel moved from science fiction to real science with
Einstein's theory of relativity, which described how large objects like
black holes warp space and time. Physicists theorize that some areas
warp so severely, they curve back onto themselves, forming a loop in
spacetime – a wormhole.
Princeton University's Richard Gott describes these cosmic oddities. "You jump into a wormhole and instantly pop out somewhere else, or into another time," he says. Nobody has ever seen a wormhole, but experiments at the Cern Large Hadron Collider in Switzerland show strong evidence of their existence.
Physicist Kip Thorne, in an article published in Physical Review Letters was the first to give respect to time travel. While acknowledging that it may be years before we develop this technology, Thorne concluded: "From a wormhole smaller than an atom, an advanced civilization might one day construct a machine that would allow time travel."
The recent possible discovery of the Higgs boson by researchers at the Cern Large Hadron Collider, have encouraged a few bold future-thinkers, to believe that the LHC might one day be able to send information with a hypothetical particle called the 'Higgs singlet' to another time.
Vanderbilt University researchers Tom Weiler and Chui Man Ho
believe Higgs singlets have the ability to jump out of our three
dimensions of space and one of time, and into a hidden dimension thought
to exist by some advanced physics models. By traveling through this
hidden dimension, these freaks of nature could move forward or backward
in time and then reappear in the future or past.
However, will we ever build machines that can transport human bodies through time? Theoretical physicist Michio Kaku sees this as a real possibility in the distant future.
Even though the laws of physics permit time travel, the idea for humans to travel backwards in time is fraught with complications. Say we go back in time and stop our parents from getting together. This would prevent us from being born; thus our journey in time could not have happened. Scientists call this a paradox. By altering events in the past, we created a present different from the one that already exists.
Clearly, mischievous time travelers from the future cannot change
today's present. People are not suddenly disappearing because a rerun of
events has prevented their birth. Therefore, something else may be
stopping future time travelers from disrupting our present, and many
experts believe they know what it is: parallel universes.
This holds that our universe, as suggested in the Gwyneth Paltro film, Sliding Doors, can split off into a myriad of alternate universes. If you travel in time and prevent your parents from meeting, you will
find
yourself in a parallel universe, one where you never existed before, a
world where you appear as a time traveler from another universe. But
beware; you may never be able to return to your original world.
In addition to traveling through time for exciting adventuring, some believe this technology, with the help of predicted advances in neuroscience, might one day be used to help deceased people regain life.
We would send information-seeking nanobots back in time with instructions to scan the brains of lost loved ones moments before they died; and then bring that scanned copy to our time and transfer it to a newly-cloned body. Because we can't change the past, our loved one's original body would still die, but a copy of their mind, with emotions and memories intact, would gain a second chance at life in our future world.
Science-fiction stories about space travel inspired us to land on the moon and explore Mars. Will time travel blogs like this article inspire us to create real time travel? Stay tuned. Comments welcome.
