Time Travel - Evaluate Chronos Technologies

I found this website a long time ago, a lot of it looks real but I'm wondering what members will think of it.

http://chronos.ws/

They present a pretty compelling set of ideas suggesting time travel is possible. Anyone interested in sifting through and seeing what makes sense and doesn't? Could be fun

Havn't read your link, but time travel is not forbidden by the laws of physics and GR.
The technology to achieve it though is way beyond us at this time, and may possibly be non achievable.

Wouldn't time travel into the past violate the 2nd Law of Thermodynamics?

I think there are speculative ways around it....not being able to go back any further then when the time machine was invented....
Time travel into the future though is relatively, theoretically easy.

 

If someone believes that one can go in the past or in the future, and can take part in the activity therein as normal human being, then my salutations to him !!

In brief: The laws of physics allow members of an exceedingly advanced civilisation to travel forward in time as fast as they might wish. Backward time travel is another matter; we do not know whether it is allowed by the laws of physics, and the answer is likely controlled by a set of physical laws that we do not yet understand at all well: the laws of quantum gravity. In order for humans to travel forward in time very rapidly, or backward (if allowed at all), we would need technology far far beyond anything we are capable of today.

 

What do you think of this fellows ideas, it seems they've invested some money there

 

Interesting. I certainly hope they are able to raise the funds to test his hypothesis.
Not sure how old the video is, but I have heard of Mallett around 5 or 6 years ago.

 

Actually, the laws of physics and GR (which "obeys" the same laws) don't specifically forbid time travel, in the sense the laws are time-symmetric.
IOW, if the earth was moving backwards in time and orbiting the sun in the reverse direction, the law of gravity wouldn't be any different.

But the second law of thermodynamics says that entropy increases, it never decreases. There are many more random states for any system than non-random states, so over all possible states, the probability is higher that a system is in a randomised state--time, or the direction time "goes", involves this probability but we aren't quite sure how yet.

 

To many problems that would happen if time travel was possible so I don't think it ever can be done. Imagine going back and killing your grandmother therefore you would never exist.

 

Symmetry of time-reversal is something completely different from time-travel being forbidden or not.

GR has solutions - like Gödel's rotating universe - which have causal loops, that means, one may, one day, appear in exactly the same event which one has already experienced in the past. With all the paradoxical elements - freedom of choice would be impossible, because it would include the freedom to kill the own grandfather.

In Newtonian theory (as well as in the Lorentz ether) such time travel nonsense is impossible, because in these theories there exists an absolute time, which is not cyclic and goes only in one direction. But the equations of above theories are symmetric for time-reversal. So, the existence of causal loops and the symmetry of the equations for time-reversal are different questions.

 

I think that might seem intuitive, but also think it's naive.

Yes, you could knock a billiard ball into a wormhole, just as the same ball emerges, knocking itself (the first one) away so it doesn't enter the wormhole it just came out of. As you say, this removes the freedom to have chosen to knock the ball into the wormhole--it denies an initial cause.

No, I don't think Newtonian mechanics says anything about the direction of time.

The symmetry of the equations isn't a question, or in question.

Plus, there is the undecided question about time being a dimension or not. If not, then what is it? It might be that we won't be able to answer this question anytime soon, if at all.
But, we have computers, abstract kinds of machines that exist very much "in" the time domain, we know how to divide time into very small chunks, but we still don't really know what it is.

 

Fraud.

 

This website crashed my iPad.

You may change the rate at which time progresses, but you may not completely stop it, nor may you in any manner alter the instant of time we perceive as 'now' in any manner that does not violate conservation of energy. When you claim that is possible, you have departed science and have entered the realm of science fiction or fantasy.

Given sufficient time and information to work with, you are free to reconstruct anyone or anything that has ever existed and/or reenact any past scenario you wish and pretend it is the past happening again, but you will be doing so with contemporary materials, and it is not time travel. Entropy and time's arrow prohibit any such fantasy from becoming a reality.

 

From Post #1 by DarkSidZz

I checked the site. It appears to be unwarranted speculation.

BTW: The laws of physics seem to be time symmetric, but actual travel to and interaction with the past seems impossible.

Post #10 by Cosmic Traveler:

The above & similar analysis indicates that interaction with the past must be impossible.

Note that observation of the past is a common phenomenon. We observe people as they were nano or micro seconds ago. We observe the sun as it was minutes ago. We observe Proxima Centauri as it was circa 4 years ago.

 

As far as relativity theory is concerned time is a dimension. That's the way the natural phenomenon is modeled. That's definitely decided. How time is modeled in theoretical models is decided. The rest of the hand wringing 'what is time' is a bunch of useless information in my estimation.

 

Time travel is a theoretical scenario allowed for by GR.
Time does come to a complete stop at "c" and the EH of a BH, although we never are a witness to that, due to the accompanying redshift to infinity.
There is no universal now, either now or in the past or the future.
Time is a non absolute entity and depends on ones FoR speed and gravitational potential.
It has been shown in experiments that time dilation occurs.
The twin paradox, although not a paradox, shows how the real effects of time travel can occur, and would occur at relativistic velocities.
All we lack is the technology to achieve such velocities, if they are in fact achievable.
Time travel into the past is another thing, and is debatable.

"Maybe backward time travel is possible, but only up to the moment that time travel is invented."

If you travel 1 year or 100 years or 1000 years thru time, where will you be & what will not be there?

A decent argument Stranger! You should equal time (i.e. be the same) to cancel it. A current theory states by simply TELLING the time (i.e. knowing it exactly (by discovering it manually)) you may cancel time as YOU and TIME are equal (i.e. the same.)

Did not try to answer the question & evidently completely misunderstood me.
