Time Travel is Science Fiction

where in part it says......
Ever since H. G. Wells' trailblazing novel "The Time Machine," time travel has been a staple of science fiction. The idea of traveling through time is deeply fascinating: you get into a machine, press a few buttons, and step out not just somewhere else, but "somewhen" else. It's easy to imagine, but can it really be done?
Yes it can, at least in a limited sense. Over a century ago, Albert Einstein showed that time is intrinsically elastic, capable of being stretched or shrunk by motion. Fly from London to New York and back, and you will leap a split second into the future of stay-at-home Londoners. The effect can easily be measured using atomic clocks and involves only billionths of a second -- too brief for a person to notice, and hardly the stuff of "Doctor Who" television series-style adventures.
 
Worth noting nearly all the links given to support the theoretical possibilities of time travel, are as I have been saying...that is along the lines of the twin paradox.

Safe isn't it ...this alignment of yours

No questioning , no creativity , no advanced thinking , just simple tow the line

Again Humour
 
In summing than our possibilities on time travel include....
[1]wormholes....[2]Relativistic speeds...[3]Alcubierre type drive drive and space/time manipulation...and the fourth method is an exclusive "paddoboy" Idea........
As our particle model improves with the LHC, would it be possible to somehow, one day in the future, for scientists to be able to manipulate the Higg's particle and field, to present a perception of no mass??
Would this be a method of fooling the Universal speed limit law?

Not so much safe, as sensible...whatever advanced thinking and creative thinking that has been put here, including the defunct Plazma Universe, are all without any evidence.
And as such, is worth nothing.

"...one single physics answering school questions."???!!!

You really should broaden your research areas dmoe,
Click to expand...
You have not the vaguest idea of how "broad" my "areas" of "research" are!

and do less of the fine tooth comb detailing you are known for
Click to expand...
One of the integral components of the real process of science is paying strict attention to the smallest of details!

[at least with that terrible mainstream cheer leader we have infesting the place]

One single seemingly self-important 70-year old puerile acting individual does NOT constitute an infestation!

and you maybe able then to see the forests that you so often miss while checking out the trees.
Click to expand...
I prefer to be fully aware of not only each individual tree in all of the different forests, but also keenly aware of all the Trolls that may be manifest in those trees and forests!

None of the research will be easy...some will require new physics, or applications we have not heard of yet, but they are not against the laws of physics or GR.
Click to expand...
And, paddoboy, what will be your contribution to of any of that research?

But as I mentioned up there somewhere, pessimism never discovered anything, did it? You do agree with that don't you?
Click to expand...
No, paddoboy, I most emphatically disagree with that! Pessimism of the "status quo" has been one of the major instigating factors responsible for the continued advancements in real science!

So why not take a leaf out of my book, and the many folks at JPL and John Glenn Labs, and brighten up.
Click to expand...
What "book" have you had published, paddoboy? And how can you possibly consider yourself the "equal" to "the many folks at JPL and John Glenn Labs"?
Are you actually so "arrogant" to actually believe that you "brighten up" the myriad of Threads that you seem to constantly contaminate with your repetitive negative responses to anything and everything that you fail to understand, comprehend or just simply disagree with? (NOTE TO MODS : The previous sentences are QUESTIONS - not ACCUSATIONS. Please take notice of the (?) question marks!)


Again, none of what has been discussed [at least by me] is against the laws of physics or GR.
Click to expand...
paddoboy, when did the "Theory of General Relativity" get promoted to a "Law"?

And are being researched.
Click to expand...
?!
 



Your usual paranoid posts dmoe as others have noted in other threads...all concerning me...all, well rubbish...
Take it easy....
 
The point is amongst all the fanatical noise, is that time travel [as per the twin paradox and other methods] along with relativistic travel [which can lead to time travel] is being researched by repuatble companies, with reputable people at their helm.

It is not going to be easy, but nothing worthwhile is easy, and pessimistic attitudes are certainly not going to help.
The companies I have listed all have the required optimistic attitudes, while at the same time realizing that it may take advances we have not heard of yet, it could even see the development of new physics......But in recognising all of that, it's also relevant that time travel does not defy the laws of physics and/or GR.

People such as Marc Millis and Dr Jemison of TauZero and the 100 year Starship Co respectively, both respected reputable individuals, are also at the coalface in this probable new era of cosmology/space exploration which by their very nature can include time travel.

An otherwise great scientist, once commented on heavier then air flying machines being Impossible....I wonder what he would say face to face with a modern day double decker Jumbo jet....
The same bloke also said words to the effect, that X-Rays were not at all promising....
He was as some may know Lord Sir William Thomson Kelvin.....

Some of his more pessimistic quotes were.....
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

"There is nothing new to be discovered in physics now, All that remains is more and more precise measurement."

"X-rays will prove to be a hoax."


When asked if he leaned toward the acceptance of any particular theory of gravitation: "No, no, no, I accept neither theory, I accept no theory of gravitation. Present science has no right to attempt to explain gravitation. We know nothing about it. We simply know nothing about it."

[Is there any matter not subject to the law of gravitation?] "I think that I may say with absolute decision that there is. We are all convinced... that ether is matter."

"I have not the smallest molecule of faith in aerial navigation other than ballooning or of the expectation of good results from any of the trials we hear of ... I would not care to be a member of the Aeronautical Society."

and finally to illustrate that even a great man can be rather mundane in quality when he is not optimistic in light of the never ending progress of science......"

the following from....
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
http://zapatopi.net/kelvin/papers/letters.html#baden-powell
In a letter to To Major Baden Baden-Powell, in reply to a request to join the moribund Aeronautical Society:

Dear Baden Powell

I am afraid I am not in the flight for “aerial navigation”. I was greatly interested in your work with kites; but I have not the smallest molecule of faith in aerial navigation other than ballooning or of expectation of good results from any of the trials we hear of. So you will understand that I would not care to be a member of the aëronautical Society.

Yours truly Kelvin

Anything allowed for by the laws of physics and GR, are theoretically possible to achieve, given time.

One cannot time travel without impacting the flow of time due to the second law. For us to time travel, will require technology and energy and unless perpetual motion is in effect, there will be an increase in entropy in both directions. This will change the past, present and future.

There is a reasonably clear consensus today which scientists claim time has no flow. When the rest of the community begins to catch up on these idea's, we will be so much better at the question of time. Otherwise, we will continue to talk about posters who believe in the flow of time, the second law and linearity of time. Oh and let us not forget the much abused subject of reversibility.

It's hard to say whether the theoretical possibilities are as strong as they were once... some of them depending on rotating universes, others parallel universes and then other branches concentrated on exotic drives.


I ask you, are we not time travelling already?

I'm not sure where rotating Universes and/or parallel Universes have to do with time travel, but my example is observed with the basic GR facts of time dilation, flexible nature of space and time, space/time, and the finite speed of light.
It's obvious if we could achieve near relativistic speeds, we could time travel as per the twins paradox.....
Other examples are wormholes.

Have a read up on Mach, rotating universes and time travel.

In the 1980's, time travel became very popular in parallel universe theory because some physicists claimed it could solve the paradoxes of time. For instance, objects like black holes not only theorized to be time travelling warp holes, but also passages to other universes.

BH's leading to other Universes is a favourite spec of mine also....as is our BB being the arse end of a WH...bUT GUESS WHAT?
I don't have evidence....it's just spec, but one day, you never know.
 
Time is a fun subject... you get all sorts of different kind of times you can try and deal with in physics, some of these include concepts of linear time, geometrical time, real time, imaginary time. Some of these exist, some doesn't and some might. Amazing insights into our universe can come about from getting rid of time. Can answer some cosmic questions about our origins as well.
 
Wormholes don't mean time travel. Wormholes mean that your present is connected to a present that is further away than normal. You can't divide space up infinitely (you can but not without evolution), so space has a distance, and the distance is speed. Planck has been used as a sort of minimum unit of division. It doesn't matter what unit we use, we can use atoms for distance. The distance between points is the speed that you are travelling. A wormhole can make that distance huge, but its now a wormhole connecting the present to a more distant present. Always the present.
