INTERESTING FACT

In theory there is a way to *cheat* time travel but it wouldn't be the same thing by definition.

Since everything we experience is really once incomprehensibly huge chain reaction of sub atomic particles and energies stemming from the big bang.

We could cheat time travel if we could exactly reverse the motion of every single particle in an area. Thus creating the desired effect of time travel but in reality you are just manipulating a reaction.

Obviously this is very impossible because to work properly you would need a machine that can manipulate everything in the universe at once.

I don't think there is anyway to travel back in time like Jurassic era or something..but you can slow down the time;)

How?
If you have got a spaceship,go on a trip around a certain black hole. Make revolution around it like earth does around the sun..beware not to get absorbed as Black hole have extremely high gravitational pull(which is enough to absorb a planet like jupiter..easily).
If you can do this..time will count slow for you and hence you can be late to step in future than your friends on earth.


Dont try this at home..it won't work :p

Mr. brian, i guess u have never read about the theory of relativity.. the time dilation which discussed in both special and general theories of relativity, shows that one can travel to future, but there is no way shown there, about coming back. if u read the theory, u can undrstand what i am telling. evrything depends upon relative speed.

Time traveling feels weird. Well, time concern numbers. And numbers? They don't exist. But either way, I have this odd and strong belief that time exist.

Forget the grandfather paradox. In order to time travel, you have to step out of 'time', or 'space' if you want. Then you can just walk back and forth.

well even if travelling at high speeds makes you travel through time a little bit, the idea of us going that fast or harnessing that speed to some sort of calculable device sseems impossible. although we can stop time if you think of heat and cold, with cold slowing down time enough to stop it.

time travel is impossible coz even if u travel faster than light...it wud mean u ahead of light,not time...coz time itself is normally constant.so time travel is merely not a possible theory since we are in the future now!tomorrow was today yesterday....ok,wat um trying to say is that we live in all these times...i don't know if u undersatand wat um tryna say but we are livin in the history's present future.*wink*

i believe that you would have to go into space to travel through time but you wouldnt have to go in light speed because time slows down in space so you would just have to sit there for ten years and come back and it would be about one hundred years that had passed

how can we create a time machine that even our body can't handle the speed of light??..

Picture this... Light takes a little over 8 minutes to get from the Sun to the Earth. It takes 4 years to travel to the nearest star Alpha Centauri. So the image we see of it now is actually four years ago. If you could travel faster than the speed of light away from it, it would look like it was going backwards in time.

Time is a unit of measurement, just like litres, gallons, meters, inches etc. So it is simply impossible to travel through "time" as that is saying you can "travel" through a unit of measurement which makes no sense. How can you travel through meters or 10 gallons? And saying you can go back and forward with measurements so therefore you can with time is silly, its just your point of refrence. The only true time travel is in things like video recordings. Time is a human creation. E's relativity to say going faster then the speed of light will allow time travel is only saying that if you travel faster then light, you "beat" the light to where it was going and can re-see what you have already seen as you have already seen that same light in the "past'. Reality is only relative to what we can see, hear or touch etc.

you could travel back in time, but the same space wouldnt be there. I think our conception of time is worthless. We create many of these false structures. You could go to the future, but theres nothing there yet. If you went back in time, I think there would be more space for a new reconing, on a parallel strip to what happend before. Im just talking out of my bum here but im just trying to think outside of the box.

I'm no physicist and so it's likely I'm wrong on this, but isn't there some idea linked with Einstein's theory of relativity, that if you travel faster than the speed of light, somehow time travel is theoretically possible?

And also, would black holes be worth a mention?

I'm not sure about these though :S

I'm no scientist either but I believe you are correct. In astronomy class I remember hearing about how when light from the sun lets say, travels past a planet, at the point when its curving around a planet it is accelerated, meaning that the light is traveling faster than it does regularly during any other time. In short, light travels at the same speed all the time expect when passing around an object. This somehow contradicts the idea that light is some sort of constant, which would also contradict the idea that nothing can go faster than "the speed of light" because actually light itself can go faster than a constant 186,000 mi/sec or what we call "the speed of light". I could be completely wrong but i thought i learned something to that effect a few semesters ago. In any case, I think we humans are such a young inhibitor that there is much we don't know, and much we are wrong about.

I think we would have something to show (like an object that was not invented at that time) if where able to go back in time. Like rigth now we could bring with us batteries or something. If the human body can "travel" back in time and stil be in one piece, than i bet almost everything can.

I think you can time travel, but only into the future, and not into the past, this is because time always and must move forward, never backwards. You can time travel to the future by moving close to the speed of light which distorts time for the person traveling at that speed. A 16 year old boy can travel at the speed of light for 2 years, come back and is 18, while all his old friends are now 60. A "time travel machine" -could- be made by creating perhaps a simple chair or pod that vibrates at the speed of light.

I think if you vibrated at the speed om light you would die, your organs would simply be destroyed.. You know, if youre driving a car on a bumpy road long enough some of your organs can separate themselves from your body.. Now thats an interessting fact :D It's nobody living in the future. We live in 2010, and year 2050 have not occured yet. We are the "future". Nobody can go back in time and show/tell us anything, because there is nobody there to do it

if we can travel only forward in time, so how can we come back to our time, if we went to the future? there's something wrong...

I m not going to say Time machine is not a true one... By the Time machine we can go to past in a very few nano seconds. But we can't feel such a changes. This is proved by research.

What about phrophets that see into the future? personally I think that the unused part of the human brain could be the key to 'time travel' in a mental state only, i dont think the technology exists yet or in our lifetimes that will allow a person to physically travel to the past or future. and also i think the implications could be drastic as said before it would possibly mean the reversing of a raindrop, what would the limits be and what would the effect be on our present day if somebody accomplishes to travel back? I have enjoyed reading these posts today good brain food

Think of time as your creation.

As we know it we beleive that there is only one time line in the universe. The only way to travel back in time is to be able to make a copy of our timeline and be able to pick a specific date to go to in the new timeline. This would create an alternate timeline that would be different to ours.

Saying this means that there must be a theory of the "first ever" time line. This will be the only time line that cannot be changed - unless it is moved forward in time.

So the only way that we will be able to go back in time is for someone to be able to save every action in the universe onto some sort of harddrive which can then be accessed by a time machine of some sort. - So the real question should be how are we going to record and save our time line before its too late?

@ Daniel: Time does exist. How else can one ever explain any sort of progression, from the smallest level to a cosmic level?

One of the most fundamental properties of the universe is change, which defines time. Obviously the universe now is very different to how it was 13 billion years ago, and this is surely not possible without time.

Time is not merely a subjective, human concept. Time passes objectively and indisputably, which is why processes such as red shift are detectable.

As for your second statement, 'of course you can't travel through [time]', every single person who is alive at this moment is doing just that.

Actually, one could say that time does not exist. Time is only the thought of what we cannot comprehend. We as the human race have given such a simple meaning and explanation to the word we call "time" that most cannot accept the fact that it does not exist. A simple example is that our definition of time is only constant to use because of the gravity vortex that controls each planet. There are so many variables that make up "time" that it is nearly impossible to explain exactly what or how to control it. Time travel is a very interesting subject, but until we can conceive how time itself works we cannot even begin to understand how to manipulate it.

Time is itself a measure. It is the measure of change. No change is a state of timelessness, which does actually exist like the breaks in a movie. Planck's time of approximately 10 to the minus 43rd power can be called a "time quanta" and is the measure used for time. In between the different states of a time quanta is the state of timelessness or 'infinity,' as in 'zero' time.

Reverse creation of change? Possible?

Maybe the humans would've been extinct by then. You never know...

that is quite interesting, but we are not talking about cheating time as in your watch. we are talking about reliving a certain moment.

so, ur plane theory is just as good as me setting my watch forward and claiming that i have travelled in time.

People time travel all the time. Only by little amounts, but you can. Moving in a plane and changing time zones allows you to step a little amount into the future. Therefore time travel isn't impossible, and is infact achieved every day of the year.

Sure, not to the extent you guys are talking like 100 years but perhaps in some way using the plane/ time zone concept it could be achieved. I have no idea, but I reckon it could be.
