I think it's fairly likely time travel will become commonplace within the next 200 years. Rather like the internet, it will be a free-for-all at first but governments will gradually try to exercise tighter control. Regulation will prove ultimately impossible and widespread use of time travel technology will lead to a breakdown in the stability of reality, something I for one would welcome.

Thanks for the compliments...I guess :)

But its true, time travel is more real than anyone here would care to admit. The problem is that when you don't see it you tend to disbelieve it. But there is ample proof out there that time travel has occurred.

Can you point us in the direction of this alleged "ample proof"? Or better yet, provide us with this proof.

Proving if you don't remember history, you are bound to make it.

There is a school of thought which suggests that once a day has done, its done forever. If it is possible to travel back in time, then it could be argued that you are not only bound to make history, but you are part of that history (and inextricably bound to that period of history) If person X travelled back to 8th May 1891, from 2001 and ran around the houses of parliment, butt naked wearing only a bluetooth earpiece, we would read about that occurence in the history books. If that school of thought is correct (once a day has done, its done forever) then NOBODY is EVER going to travel back in time to the 8th May 1891 and run around the houses of parliment wearing a bluetooth earpiece, because NO such occurence has been recorded.

As said before, if we watch a film from 1891, we are transported back to 1891. That is a form of time travel. Primitive, but it is the basis.

When I watch a film from 1891, I am not transported back to that time, because I am well aware that 1891 is not some black & white, undersaturated, grainy, vignetted period in time.

True but trivial (trivial not in the demeaning sense but as used in math and science).

 

Everything that you perceive; given the speed of light, the speed of sound, the speed of neurotransmission, etc.; is a view of the past once the signal is received. All sensory inputs are transmitted over a given distance and it takes some period of time to arrive at and be processed by the receiver. The film simply captured the light signal and used the energy to convert it to a chemical compound that further delayed the period of transmission. It is, however, trivially true to equate that to time travel.

Of course, when light reflects off of a surface and hits our eyes, we are seeing that surface as it was at the time light reflected off of it. Now imagine that everything we experience is being recorded like an 1891 movie. Our eyes, our brains, the neurons. This is nature's television and HD recorder. Imagine that in the future we will have Google Glasses that record everything we experience. I then come to your home, we have dinner, and I give you my Google Glasses. You put the glasses on and you experience my past -- for real, you have just time travelled to my immediate past. Now, in reality, you did not travel to the past of this universe. But what if many years from now -- you could?

 

I am also referring here to an old movie called "BrainStorm".

That's the point I was making. We don't have to imagine it nor is it anything special. That is precisely how nature (the laws of physics) works, i.e. it is absolutely the normal situation for all signals transmission. It isn't what we are calling time travel, however. Time travel, especially to the past rather than receiving naturally delayed signals from the past, is an exceptional situation that either edges up against the bound of what the laws of physics allow or is in reality forbidden by the laws of physics. We still don't know which answer is correct.

Reminds me of the Saccade effect...

 

"When voluntary saccadic eye movements are made to a silently ticking clock, observers sometimes think that the second hand takes longer than normal to move to its next position1. For a short period, the clock appears to have stopped (chronostasis). Here we show that the illusion occurs because the brain extends the percept of the saccadic target backwards in time to just before the onset of the saccade. This occurs every time we move the eyes but it is only perceived when an external time reference alerts us to the phenomenon. The illusion does not seem to depend on the shift of spatial attention that accompanies the saccade. However, if the target is moved unpredictably during the saccade, breaking perception of the target's spatial continuity, then the illusion disappears."

But that's not the point I'm attempting to get across.

 

When you look at something - your computer screen, your car, friend, a tree, yourself in a mirror, whatever...

 

The object that you are looking at is some distance from you. The image of that object is carried to you through photons. It took those photons, traveling at the speed of light, a period of time to travel from the object to your eyes. When the photons strike the rods and cones in your eyes the event that you see is already well into the past. You are perceiving something that has already occured but which no longer exists in the state that you see it. You can never observe an object as it "is" because that statement is without meaning relative to the reality that we are physically able to perceive. This is a concept far more mysterious than any New Age crap such as is frequently posted here and elsewhere. New Agers have absolutely no imagination. They are, in the main, rather dull and boring people in that regard.

 

But that is not time travel. It is our normal, everyday, common existence. It is the essence of reality. Not an illusion, trick of the mind, saccadian movement or anything else. It is the fabric of spacetime in a world where the speed of light is both finite and fixed.

 

And that reality is embodied by Special Relativity.

 

1 sec ~= 300,000,000 m

 

1 m ~= 1/300,000,000 sec

 

Or 1 foot ~= 1 billionth of a second. When you look at something, measure the the number of feet that the object is away from you and multiply that number by 1 billionth of a second. That's how far into the past the image came from.

I read the following in her article...

 

I read somewhere once that Einstein theorized space is curved. Swedish mathematician Klein proposed that our three known dimensions hide deep within them a fourth dimension known as "curled," or like a circle.

 

...and that's all I needed to read.

 

For Christ's sake, Thomas. The two sentences fully reveal her knowledge and timliness about physics. The two sentences are statements about the state of physics that existed in the mid-1920's.

 

Need I say more?

I undestand where you're coming from now. But given what you've said, how accurate can measurements involving time etc, really be?

Just wondering how many people here actually believe that time travel could be possible.

I do believe in time travel.

 

I think astral projection would take you any time of your personal live, I mean childhood or youth and also to your immediate future but ONLY as an viewer, I can tell about a dozen of witness who certainly saw, talk and act in a different way, in situations that have passed and did not alter at all the present. BUT on the other hand, for future events they were able to avoid o change details that previously happened..

 

That's all

The problem is, from a scientific perspective, that there is a serious flaw in such thinking.

It implies that astral projection is 'not physical'. If that is the case...then how does something that is not physical interact with the physical world ? The very definition of 'physical' is existence and interaction with the rest of the world. It is thus a complete logical contradiction to have a non-physical object interact with the physical world.

 

The biggest problem with 'astral' stuff is that if it cannot be weighed or measured or found to interact electromagnetically ( which it would HAVE to do for an astral body to 'see' the world ) then what conceivable evidence can there ever be that it exists ?

 

Something that cannot be scientifically demonstrated to exist seems an awful lot to me to have exactly the same characteristics as something that doesn't exist at all.

That is because science is as limited as religion.

 

I ask of you: Scientifically explain to me the presence of a thought, that does exist in one's own mind. It cannot be weighed, or measured, and its' not fully understood to be electromagnetic phenomena.

Yikes! Hope one doesn’t roam into the Milky Way galaxy anywhere near Earth, or we will be toast.It has been predicted that the matter the black-hole attracts doesn’t collapse into a single point,but rather gushes out a “white-hole” at the other end of the black hole. you may refer this to know more about time machine..
