Re: A reason

 

Chrono

 

The main reason a new area has been created, in my opinion, is because there had been some quite marvelous threads starting on, with outstanding opportunities for self-discovery and one too many persons with disregard for the topic had introduced unnecessary comments making the thread dull and ultimately killing it.

 

Enjoy the new opportunity, yes, it is probable that now not many will pay attention to your ramblings but hey your 15 minutes of fame are over. Go to the new zone and post there about your mission and thinks. Of course that you can post in the time travel section with the other mature people, but you should post mature things and not fantastic dreams.

 

Until later becomes now.

Transient001-well I never made it dull because I haven't talked in most of the threads.

 

I am not telling fantastic dreams.

Hmm, if you aren't lying, then have you thought about seeing a psychiatrist? They have some very good meds on the market now.

Siegmund-what have I done to get banned?

 

Rhudey-I am not insane either

Re: A reason

 

I'm out of here, and Chronohistorian and similar posters are the reason. This board needs some more discipline to function properly. Otherwise Chronic et al will continually appear in every conceivable thread and that just isn't good enough for me. No offence.

I think that if someone has a problem with their fellow travelors posts, it is indeed time for an attitude adjustment. I just took a walk with Pope Pious and asked him if he ever felt discouraged, and he told me that there will always someone trying to jump on your cloud. Trying mightily to bring you down and sap your spirit. He told Doug and me that we have to hang tough and wait them out. I think of that as I jump from time period to time period, always in slow motion and always with that creepy Irwin Allen music. Ah well, things are tough all over

Hi, I'm Doug .. this is Tony. We come to you through the time tunnel. We need help to get back home.

Time Travel

 

Time travel is the concept of traveling forward and backward to different points in time, much as we do through space.

 

Unsolved problems in physics: Is time travel theoretically possible? Is it practically possible? If so, what are we to make of the time travel paradoxes, such as going back in time and killing one's own grandfather, etc.?

 

Humans are in fact always traveling in time ­ in a linear fashion, from the present to the immediate future, inexorably, until death.

 

Some theories are predicated on the fact that we move forward in time, and both forward and backward in space. Since time and space have been shown to be intrinsically linked, travelling forwards and backwards through time is not a theoretical impossibility.

 

Currently, traveling at speeds approaching the speed of light can cause time dilation, the effects of which cause the individual traveling to pass through time more slowly. From the perspective of the traveler, external time would be going much faster, causing the traveler, upon stopping, to arrive at a place farther in the future.

 

Often it is a plot device used in science fiction and many movies and television shows to set a character in a particular time not their own, and explore the character's interaction with the people and technology of that time - as a kind of culture shock.

 

Other ramifications explored are change and reactions to it, parallel universes, and alternative history where some little event took place or didn't take place, but causes large changes in the future.

Re: Time Travel

 

"but you have a time travel forum so why can't time travellers go there? why do you have to segregate us?"

 

Is it really segregation or is it just organisation...

 

i think it would be much better like that - or everything just gets all mixed up - and then it becomes impossable to seperate fact from fiction (and im not saying you are fiction - so lets not start up that arugument again - i dont care if you are a time travler or not - i just care that if im reading scientific posts that its not mixed up with claims of time travel as well)

Re: Time Travel

You're correct here. Based solely on First Principles of GR it is theoretically possible to move backwards in time. There are many differential solutions to GR that clearly predict this form of time travel. But those solutions appear to be math rather than physics based. Simply because an equation that predicts time travel can be derived from GR doesn't mean that the the conditions assumed in the solutions describe our universe.

 

If we stay with GR, which is a classical form of physics, we instantly run into problems when we go beyond first principles.

 

Let's suppose that we build a time machine that successfully creates a CTC (closed timelike curve) and run a photon through the CTC.

 

Photons mediate the electromagnetic force and posess their own EM field. The spacetime around the CTC is very energetic, to say the least. As the photon moves through this region of spacetime it gains an energy boost. If you set up the loop intergral for this problem you immediately see the problem. The photon gets a boost every time it makes a complete circuit along the curve. In the classical solution when we go beyond first principles the photon's energy goes to infinity...the solution blows up.

 

This is just one example of the Chronology Protection Conjecture at work.

 

Basing the problem on first principles just doesn't work. Hawking's Chronology Protection Conjecture isn't a wild guess based on an unjustified prejudice against time machines. The conjecture is based on the results of looking deeply into GR and quantum mechanics and discovering the real world physical constraints on time travel.

 

This doesn't mean that time travel isn't possible. It just means that it appears that every time travel solution so far discovered has run up against real physical laws that prevent time travel.

 

 

Just another damned cowboy with a college education.
