2008: Does time travel start here?

I've read this elsewhere. But I'm not clear on it. Is it to say, that once the machine has been activated, we will see an influx of time travelers? I still don't understand why 08 would be year 0. Let's say that this machine does open a vortex of sorts. Obviously, in our future 08. Lets say, May of 08. Well, then we would already know, because they would be time traveling back and forth in time already. So its easier to think that from 08, you can only move into the future, since we have no knowledge of any time travelers now. But many argue that you can only go backwards in time, if time travel is possible at all, but most seem to want to go forward.

So i guess I'm confused by this! /ttiforum/images/graemlins/smile.gif
 
Risata,

I believe the current thinking by most prominent physicists is that one will only be able to travel back to the time when the first "time machine" is activated. So then until the point when LHC is turned on (and I, for one, do NOT accept that it will close timelike curves in spacetime) we would NOT see any time travelers. The idea is that a time machine acts to "close the loop" on timelike curves... which is what makes them CTCs (Closed Time-like Curves), which then allows "travellers" to utilize them to travel backwards or forewards in time from the point the CTCs are activated.

But I don't believe all this....not yet. Jury is still out AFAIAC.

Risata:

Just Because they somehow prove mathematically with the AtomSmasher that particle time travel is possible does not mean that human time travel takes place the next day.
I truly don't know if they will ever prove this, but I do hope they find more clues for building a better model on how the Universe works.


The 2 Decade Six Billion dollar Experiment [Video]
http://video.google.com/videoplay?docid=6454521153918323669&hl=en

Around Minute 28:30

6 billions to hopefully find how the universe works and answer: what is Mass?...Will they finally find the Higgs boson?

Or like someone posted in another forum:
"All of the black holes in the universe, well they were civilizations that wanted to experiment with particle acceleration and BAM!!! Looks like we are about to join the cosmic dunce club"
 
Risata,

Admittedly, I didn't pay the $4.95 to download the rest of the article, so I'm only surmising what the rest of the article says based on what I know about physics...

The blurb suggests the following:

1. If the LHD manages to create a closed timelike curve and

2. If time travel is actually possible, then

3. The closed timelike curve will always lead back to the instant that the CTC was created in the LHD.

That makes perfect sense. If you draw a loop you can only travel around the the circumference of the loop, not outside of it. Therefore, if you create a spacetime loop you can only travel the circumference of the CTC. You can't travel any farther into the past than when it was created because no spacetime point on the CTC lays in the past of the time that it was created. But this isn't startling news - it's a theory of spacetime that has been known for at least 70 years.

But even if they manage to create such a loop it isn't going to allow time travel. The event horizon of a black hole created by a proton-neutron collision will be so small that no particle could even enter it. It would, in theory, be smaller than Planck's length which means that it doesn't actually exist.

And wa1ex is correct. Even if they opened the LHC tomorrow and did their expreiment before noon, the experimental results wouldn't be in for 18 months to 2 years. Add another year for peer review. Sometime in 2010-2011 the results would be verified. Add a century after that and maybe...just maybe...a macro mass, something that can actually be seen with a microscope, could be tossed through the event horizon and be detected sometime in the past.

You might think, what? A century later?! We've been attempting space exploration for half a century. In those 50 or so years we've left Earth with manned vehicles three times. Sure, we've put a lot of satellites and manned orbiters up but they have never left Earth. They orbit just above the atmosphere much less than one Earth radius up in the "heavens". And that's mostly an engineering issue - not a theoretical physics problem.
 
Hmmm. Thank you for the answers. So does that mean, in theory, that you would not be able to travel in anything less than 08? For example, I wouldn't be able to visit 2006 again, because the LHC had not been run yet?

Still kinda confusing. I am however, looking forward to the experiment because I do think it will bring us closer to understanding quantum physics and may even introduce us to a new form of energy we have yet to discover. Which is fascinating in and of itself....
 
My apologies in advanced for providing a link to a short read followed by a subscription page....I guess everyone needs to make a living now days

*** If predictions by theoretical physicists about wormholes are correct, a new experiment with the Large Hadron Collider could create an opportunity -- the first in the history of planet Earth -- for an advanced civilization, human or extraterrestrial, perhaps millions of years ahead, to send information, objects or even beings to us here on Earth in 2008. The "Year Zero" event could open a gateway to other times and places. Even if we lack the technology to use the gateway, an advanced civilization could exploit the portal, especially if they knew exactly when and where it was opened. Some form of uncontrolled accidental/incidental exchange between different points in space/time could also occur during the event. All of this is within the realms of current scientific knowledge and theory. ***

I used to help design particle accellerators. And while I was just one of many, I knew, more than many of the people who were paid more than me, what the machine was capible of. The target building (were the beam ends) was the size of a football field, yet I have a feeling though that the energies used in the one I was working on only had the cability of creating a bouyant zone of a few centimeters. That was a few years ago, and I assume they have up'd the technolgy, not to mention, the one I was working on was just the public show horse.

CERN is another "public show", but the Swiss are much more transparent at tipping thier hand. I also believe the rest of the world (china, Russia, middle east, UK, Germany, etc) are not even close to the capability of the grand USA. But when it comes to things like this, the USA builds under military contract and the public doesn't get to know about it until 50 years later. Rest assured though, if anyone is using a time machine, its the old US out there in the desert, burried in solid rock. ;-)
