all these theories will remain as theories until they are proven. if those scientists can theorize, y cant I?

According to The C-Note theory, anything that travels at the speed of light will be annihilated and vanish into thin air.

prove me wrong.

Do you have any mathematics at all to back up your theory? What is your proposed mechanism of annihilation? Where does the free energy that is created go to? Another dimension? Perhaps if you could answer these questions with some valid math, then your C-Note theory might even be considered among the many existing competing theories

Thats the thing about theoretical physics. The scientists arent acutally sitting around folding pieces of paper and calling these their "theories" They start of with a certain accepted theory, crunch the numbers, solve the equations, and find a solution from there. At times the analogies produce their work, but other times, are infact a result of their calculations

Gotta admit this is the first time i hear of this term. Upon reading up, it has to do with tunneling of spacetime. This is where Einstein's General Relativity explains it.
Curvature of spacetime makes it LOOK like a particle beat light to a point, when infact the particle took a shortcut. Just that.

When dealing with quantum conditions, such observations include the quantum leap. Which is yet to be completely explained.
Current theories still hold.

Maybe there is such a thing as time travelling. Everyone is working on it right? The country that has this technology would be the first to rule the world.

Even if TIME is recorded, what good does it do?

Since it is so fascinating to talk about theory when we are in the well, think about what would you do after that when you jump out the well looking at the whole picture.
Jump here and there to rectify or alter the past for an ideal future, if doesn't turn out to be the way you prefer, go back and do it differently, I think it is stupid, I choose not to be born instead.

This whole idea is just for the sake of argument for those who think linear.

Mainly because most of the ideas posted here are by people who didn't read the previous posts on the true concept of time travel as we apply it.

It is by no means for the sake of argument.

Did you know that GPS technology rely heavily on correcting time difference caused by time dilation? else the internal clocks in the satellite will go off-sync very fast. And even an off-sync on the scale of micro seconds can be catastrophic in navigation.

Time dilation is gravitational effect on device only, time is created as a standard to measure but everything has its own time such as some animal can move and react faster, plant grow at much slower pace and when parts of them are eaten by animals, the others begin to develop defence mechanism by generate poison & thorn.

Put aside possibilities, if just one human can achieve time travel, that person can leap in and out across time zone would make him GOD. Make everyone worship the living god and how far into the future or the beginning? By then you will wonder what medium is holding time and want to transform out of human body to become a divine power.

MATRIX movie; If there is a beginning, there is an end. When we know how we are going to end, everything else is meaningless, we continue to live because we don’t know the limit.

I don't think you quite grasp the concept of what time is as discussed in this topic. Firstly time is no more a creation of man than is physical space. Both are innate quantities in the universe, and are universal in accordance to physical laws.

Secondly no medium holds time, time IS the medium. And the measurements that we make, i.e. with clocks, measure the changes in this medium. Similarly no medium holds physical space, space is the medium in which we measure distances. As to what's beyond these, well there's just no concrete answer.

You could argue about the existence of higher layers of abstraction (what's beyond the universe?) but they're strictly in the realms of theoretical physics, such as string theory and the like, and is of a separate scope altogether.

I also disagree with the notion that time dilation is not a form of time travel--because it can be. Make it so that you travel fast enough (say, 99.9% of the speed of light), manipulate your own (perceived) travel time, and you can travel to (nearly) any arbitrary point in the future.

So, convince me in simple English that the future is already made in advanced time because to travel through time is like playing back & forth video recordings.

How to even conceive this idea without explaining the medium that act like the video recording device? Yet time is abstract? Sounded more like science fiction here.

Time dilation is only the speed of time, if you accelerate plant time, you can see them grow right before your eyes never suggest that it can reverse time.

The future is yet to be made.

If you travel forward in time, whatever happen while you were moving through this time is beyond your control. It will happen as if you have disappear. This travel is also a one way travel. There is no turning back.

Even you said it. Its on the device only. The device has travel forward in time by the nano-second ( on my example of GPS satelite ).

There is already lengthy 'simple' english explanation on this a few pages back. So do read those, don't make me copy paste my own post.


Added on September 9, 2009, 8:46 pmAnother important thing to note is the limit of speed, you won't be able to see an appreciable amount of growth ( on your plant example ) because you will never get something that big to reach even half the speed of light.

Dropping such thing into blackholes is beyond question as you will never get to observe what happen unless you found that a wormhole exits somewhere else. Yet another debatable subject.

The future or the past, it is a destination. The future must already be made for you to reach. If you suggest that it is only one way means you are not traveling but DELAYING time in simple English.

You are only thinking of the mode of transport to achieve "light speed", worm hole and black hole but none of these suggest it move between time and the implication that time can be traveled as a destination ultimately means it is RECORDED in a medium.

We are already time traveling, the airplane can fly us to time zone one day later from Malaysia and people from the other half can travel one day forward. So the mode of transportation is what everyone talking about as if the future is made or the past is still there. Every breath you take, every single molecule has to be recorded in time so that when you found a way to go back, they are there.

Delay time as if travelling forward is not Time Travel, it only mean to preserve a primitive body to see the future and you are likely to live in a container nothing more than just exhibit to advance human environment.

Travelling between time zones is not time travel. Time zones are artificial constructs, created so that our clocks are consistent (with respect to daylight, etc) anywhere in the world.

Also I have no idea what you're going on about.

All I stated is doubt while everyone rush to provide theories. Science geek always dwell on methods but here, before you can even talk about time travel, my question is What is time? Human time, plant time or is it universe time?

The only rational thing is delay time rather than travel across time. I describe what time means to refresh your mind of the definition of time itself before you can say travel between it or do you expect every opinion to offer the method of transport?

Say the destination is the year 2020, fine out how to go there or go back one hour ago and expect every molecule is at where it was, something must have recorded time, fine out what this medium is and then you can think about how to travel in time.

The reason why we don't have doubts when posting about this is that this theory has already been proven experimentally. It is difficult to explain it in normal words because it really can't be. I'm sure even the greatest artist in the world will have trouble drawing up a 4-dimensional picture.

To your question on what is time, time is nothing. So is space, it is nothing. Thus we have this thing called spacetime( another thing that is proven and described mathematically ). The term 'time travel' is thought up while sort of relating the term travel and space. It is just a term.

The whole of it is like what you said it. It is just delaying time of your inertial frame. There is no space destination, neither is there a time destination. All you have is spacetime. There is no medium for space or time. Space and time IS the medium. You travel through the medium, not TO the medium.

Like i said before, this concept is very abstract in application of large objects. You need alot of hypothetical conditions for human 'time travel'.

The fact is that this 'time travel' is already a proven theory. Though (im saying this again, the post is even on the same page) many people simply refuse to read up on the real details and assume we are trying to prove time travel like you see in movies.

I also quote this posted by another one of our forumer incase you think that im talking nonsense and making things up

Also, if you're truly interested in relativity, take a book and read about it. The math isn't very hard at all, it's just Add Math you did in F4, pretty much (or simpler). It's the physical implications that boggle the minds of students learning the subject till today.


Once again, time travel is just a term people use. Don't get distracted by the people here who don't read previous posts and assume their own things.

As for time travelling, i can only say that human still has a long way to fully understand the nature. Even now we have several theories explain phenomenon that we observed, including time dilation, space-time deformation and other effects using theory in physics developed, those theory sometimes still cannot explain quite some phenomenon(even the quantum mechanics and Theory of relativity still have some part contradict to each other, there is still no theory that can unify all the fundamental force in one formula). So, until we get more understanding on the nature, we have the opportunity for time travelling. However, one got to keep in mind that according to Gödel's incompleteness theorems, no matter how complete a theory is, there will still be some case the theory not valid. So, a theory always need to be refined from time to time.

maybe a more accurate thing would be we are all time-travelling to the future, you're time travelling every second you're living

I happen to read a book on Blackholes and time travel once. A blackhole is actually a vortex - like tunnel which will suck EVERYTHING including LIGHT itself towards its other ends. Actually, you CAN time travel by doing so, since the blackhole itself have a suction speed equal to that of speed of light. However, you will DIE. Why? Because the speed is so intense and the state of "singularity" applies where everything that is being sucked in MUST exist as a single particle i.e. you will gradually lose your body, (sorta like in the
FF7 where sephiroth dies in the end).

Regarding the speed of light, Albert Einstein did illustrate it using simple math and trigonometry, yeah pretty simple. I watched it on NATGEO. When your vehicle reaches the speed of light, the light surrounding your vehicle will gradually become attracted to your vehicle, the scenery from outside your vehicle seems to bend, then, all the light will surround your vehicle until eventually you will be covered by the light itself. Then, time travel is said to occur.

Well yes, that is obvious. The term "time travel" as it is applied here in this topic is accelerated time travelling either backwards or forwards. In fact the term has, and always has been, referring to this very concept, regardless of context. I didn't think there would be any confusion surrounding the meaning.
