Time Travel Possible?

[seangraves]

if yalook at this way we all travellin through time ,slowly one way though forward ,stick ta this ,,,live ta day cherish yestaday dream ta mora..our minds wouldnt cope going through all the future changes thats gonna happen in the future if we could fast forward time ,,just imagine wakin up ta mora un time leaped 50year ,,,,all the changes would be mind blowing ...

no time travel is not possible,
it is just a wave form like sound - we can break the sound barrier but do we travel back in sound - no - we just can not perceive the sound correctly - same applies to visual spectrum also - just a waveform that we can maybe distort slightly, or if we could go faster than light, that is all we are doing - we are not travelling in time, just travelling faster than the light spectrum - if you travel from one point to another and travel faster than the light getting from a to b - all you will see when you stop at b is what is the light spcectrum actually happening in TIME at point b, not what light has travelled from point a to point b when it catches up to point b as point b has its own light spectrum already existing in the current TIME. Time and light are not the same thing.

with a little understanding of the physics involved, you'd realise how little sense what you posted makes.
you cant treat light, mass, time and speed as if they are different. they are all part of the same thing.

Traveling forward in time-yes, mainly due to the effects of time dilation. Hell, there are cosmonauts that are nearly a second younger than they were prior to their spaceflights! This is on a very small scale, but given proper speeds (even speeds currently attainable given our level of technology) a significant difference in time (relative to the observer) can be achieved.

Traveling backwards in time-undetermined.

...this intrigues me...I do get 'the point' for sure.

...it is a topic debated many-fold.
This is purely banter,as I don't reckon any of us are scientists,nor experts in this field...they can tell use whatever they like...and to be honest,who would question them from outside of their peer-group...no-one,that's who.
The work scientists do in various subjects is of extreme importance to mankind for sure...only problem with this particular study,and others like them,for me,is this...
-what do they aim to achieve,and at what monetary cost?
With so much to be done for a greater good in this world...I don't personally think this will aid shit...apologies for being blunt,but tell me I'm far wrong...?
...in a way I'm just stating that it is ultimately a pointless argument,be it for or against...the theory,practicality,even physicality of the notion that is time travel...and surely saying time travel is impossible is a really safe bet. If it should turn out in the future that time travel in a physical sense is a go,then I can always go back in time and change my statement...!

...not really....as the article states:
"Extraordinary claims require extraordinary evidence, and this is an extraordinary claim.***8221;

...and to the point...

...it has not been formally checked by an external source 'yet'...until that time,just because THEY have found nothing...that doesn't mean to say that it is ANYTHING.

As the chap in the earlier paragraph says..."possible in theory"

...it is purely a personal opinion whether this is possible in general...or not...and to answer the thread which was originally posted..."Time travel Possible?"...my answer and opinion is...no!

your missing the point.
there has to be a continuing difference in time between two clocks, originally set to exactly to the same time
one in orbit (generalising here)) one on the ground for GPS to work at all.
this experimentally proves that things can travel in time, in relation to the terrestrial viewer.
and that's time travel anyway you slice it.
it also experimentally proves mass slows time down.

GPS does not in theory work , it in fact works
but it wouldn't if the theory/s it was based on were incorrect.

Ahhh........here we go, another blind poster. If you read this thread in its entirety you will see time travel is already possible. Sat nav won't work without it..........it may not be your idea of TT but it proves the fact it can and will be possible.

I found myself reading that with his voice in my head

Oh yes, me also. and, very probably, everyone else who reeds it too.
he steadfastly refuses to change the style of his electronic voice.
and considers it his TRUE voice.

anywho, did it help to clear anything up?

i just wish to clear one things up. in terns of my posts.

I speak of "speed" causing time dilation. Hawkins talks of "mass".
as your mass, or any mass, increases as speed gets higher.
when i post i tend to use the term "speed" as a catch-all.

, you think the possibility of time travel is hard to get your head around
just try to explain why a satellite in space though weightless ( actually its in micro gravity) still weighs the same, (actually it has the same mass) when you try to catch, hold or work on it, as it does on earth.

maybe this will help.

if you read on you will find how Hawking explains how mass and speed can be used in order to travel forwards in time.

beyond this method it seems time travel is not possible.
but, as yet, we dont understand how time effects the Quantum world. or indeed if it even exists there.

we know in the Atomic world (the only one we can currently see/perceive) time travels in only one direction. And that's forward.

Scientists are working on theories as to how it works elsewhere (if at all).
as they are scientists these are called "theories".
but you and i know them as "guesses".

and, to be honest, your guess is as good as theirs or mine.

Thanks wish i understood but its beyond my comprehension i will just write it off as an impossiblity

and see if im proved wrong by a real life Doctor

maybe this will help.

I do believe in time travel. Time travel to the future. Time flows like a river and it seems as if each of us is carried relentlessly along by time's current. But time is like a river in another way. It flows at different speeds in different places and that is the key to travelling into the future. This idea was first proposed by Albert Einstein over 100 years ago. He realised that there should be places where time slows down, and others where time speeds up. He was absolutely right. And the proof is right above our heads. Up in space.

This is the Global Positioning System, or GPS. A network of satellites is in orbit around Earth. The satellites make satellite navigation possible. But they also reveal that time runs faster in space than it does down on Earth. Inside each spacecraft is a very precise clock. But despite being so accurate, they all gain around a third of a billionth of a second every day. The system has to correct for the drift, otherwise that tiny difference would upset the whole system, causing every GPS device on Earth to go out by about six miles a day. You can just imagine the mayhem that that would cause.

The problem doesn't lie with the clocks. They run fast because time itself runs faster in space than it does down below. And the reason for this extraordinary effect is the mass of the Earth. Einstein realised that matter drags on time and slows it down like the slow part of a river. The heavier the object, the more it drags on time. And this startling reality is what opens the door to the possibility of time travel to the future.

not going to even pretend i understand but if you travel from earth at same speed for ten years then travel back the same speed for ten years

isnt it just the same but 20 years have gone by


isnt the term time travel relevant to being in the same place ie earth?

On the time thing NO.
time is dilated (run slower) even for satellites travelling round the earth @ 32,000 mph. only by fractions of a second though.
though its true, the dilation would be in proportion to the speed.

and Errrrr yes.
For those travelling on the craft only 20 years would have elapsed.

thing is, the universe does its best to maintain "relativity".
time is dilated in order to stop fast things exceeding the speed of light. ( or, more correctly, stop light going faster than 5.9 million million mph)
the faster you go the more time is dilated, but only for those outside or "LOOKING" at the craft. the traveller experiences time pass at a "normal"(?) rate

I see your point on the Time travel thing.
but, stood still or travelling, if there is any difference in time between the "Time Traveller" and the observer.
one or the other must have moved in time.

the advantage of using speed is that you dont have to worry that there is a time machine in the time you are travelling to, in order to get back or move on.
because you brought it with you.
the only problem here is you can only travel forwards in time.

two thing with static time travel.
1, time could not, if it were possible, be linear.
2, as stated else where, you could only travel back or forward to where there is already a time machine.
