That strange feeling is your head spinning.

Is The Large Hadron Collider Being Sabotaged from the Future?

The quest to observe the Higgs boson has certainly been plagued by its share of troubles, from the cancellation of the Superconducting Supercollider in 1993 to the Large Hadron Collider's streak of technical troubles. In fact, the projects have suffered such bad luck that Holger Bech Nielsen of the Niels Bohr Institute in Copenhagen and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto wonder if it isn't bad luck at all, but future influences rippling back to sabotage them. In papers like "Test of Effect From Future in Large Hadron Collider: a Proposal" and "Search for Future Influence From LHC," they put forth the notion that observing the Higgs boson would be such an abhorrent event that the future is actually trying to prevent it from happening.

Philip K. Dick's Reality (Tessa Dick)

The time travelers, or time meddlers, sometimes enter our reality to observe us, and they appeared quite shocked whenever they realized that Phil could see them. They did occasionally communicate with him. They claimed to come from a time that is neither the past nor the future, but outside of our time. Phil most often thought that they were humans, not aliens, but genetically altered in some way.

Time travellers from the future 'could be here in weeks'

Prof Irina Aref'eva and Dr Igor Volovich, mathematical physicists at the Steklov Mathematical Institute in Moscow believe that the vast experiment at CERN, the European particle physics centre near Geneva in Switzerland, may turn out to be the world's first time machine, reports New Scientist.

The debut in early summer could provide a landmark because travelling into the past is only possible - if it is possible at all - as far back as the point of creation of the first time machine.

That means 2008 could become "Year Zero" for temporal travel, they argue.

Centauri Dreams on the Large Hadron Collider's possible utility as a time-machine:

But as to the argument that the LHC's operations could establish Year Zero for time travelers (creating the needed first instance of a time machine to which future travelers would be able to return), I'll take a pass. Surely if massive energies are what it takes to establish such a wormhole (itself a purely theoretical concept, and one that requires yet another theoretical idea -- phantom energy -- to hold it open), then the universe has supplied us with previous instances of 'closed time-like curves' in highly energetic events reaching back to the Big Bang. Does that mean a time traveler could only travel back 13.7 billion years? If so, that's plenty of temporal territory to play in, but the Fermi question equivalent for time travelers is, where are they?

Stephen Hawking has used the same argument. If time travel is possible, he maintains, we should see a steady influx of "tourists" from our own future. This reasoning is easily as limited as the assumption that ET visitors will "land on the White House lawn" if they happen to visit.

The Daily Grail makes an astute observation re. my comments about time travel:

Scifi writer and ufology buff Mac Tonnies takes on Stephen Hawking over time travel. Mac, you can say you kicked Stephen Hawking's ass, or you can say you got your ass kicked by Stephen Hawking...but either way, it's not gonna pick up girls at the bar.

But what about girls in coffeeshops?

Time Travel: Fact or Fiction? (in which I attempt to refute Stephen Hawking's silly notion that time travel is impossible because we're not chatting it up with our future selves)

Tonnies continues: "Other physicists are at work refuting the paradox of going back in time and killing your parents before you are born. If they're right, a time traveler from the future could interact with others, including his or her past self, so long as no action was taken that would endanger the traveler's own continued existence. It's difficult to visualize how this might work, although the idea makes logical sense. Maybe the best analogy would be a physical system that relies on a principle of least action, such as a ball rolling inexorably downhill."

He further notes: "The fascinating upshot of this is that there's a chance we're indeed being visited by advanced beings from our own future, but their interactions with us would be necessarily limited lest they doom themselves to nonexistence."

Tonnies also wonders if the many UFO sightings that have been reported for decades may not be due to the actions of aliens from the other side of the galaxy, but the result of time-traveling humans masquerading as ET to keep secret their real point of origin.

"If time travel is possible," says Tonnies, "the behavior of UFOs may be at least partially explained: formal contact with us would result in a causality violation of some sort, so they must remain content with maintaining their presence behind a curtain of subterfuge."

Parallel universe proof boosts time travel hopes

But the existence of parallel worlds offers a way around these troublesome paradoxes, according to David Deutsch of Oxford University, a highly respected proponent of quantum theory, the deeply mathematical, successful and baffling theory of the atomic world.

He argues that time travel shifts between different branches of reality, basing his claim on parallel universes, the so-called "many-worlds" formulation of quantum theory.

The new work bolsters his claim that quantum theory does not forbid time travel. "It does sidestep it. You go into another universe," he said yesterday, though he admits that there is still a way to go to find schemes to manipulate space and time in a way that makes time hops possible.

Suppose someone's figured it out. They're wouldn't be violating causality, so they could enjoy a surprising degree of freedom. If they're a version of homo sapiens, it wouldn't be unreasonable to expect them to be interested in us, in which case some UFO testimony begins to make sense.

As Deutsch is careful to note, quantum time travel doesn't seem to be possible anytime soon. So if popularly described "aliens" are in fact terrestrial visitors from a version of our own future, how advanced are they?

New Theoretical Model Eliminates Barriers to Time Travel

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.

Of Time Travel and Funding

Traveling to the planets takes big money and we've been part of the squabbing over where NASA money in particular ought to be allocated. But what about projects that take small money? The term is relative, of course, but John Cramer (University of Washington) thinks $20,000 should suffice to run his experiment in time travel, and with NASA's Institute for Advanced Concepts now shutting down, he's having a hard time raising it.

Read on. I can't help but feel Cramer's idea -- if validated -- might have some practical benefits for the computer industry. Perhaps instead of petitioning the NASA bureaucracy he should approach the likes of Bill Gates.
