Some scientists even believe that time travelling existed and the people who travelled in time were advised to camouflage their identities and go along with the people in their time.(but, I do not believe this is true). Stephen hawking has also given a detailed account on time travelling. Interested CEans can go through this.

Many believe that time travelling can be only possible if the concept of parallel universe is true, because the absence of parallel universes will lead to many paradoxes,like Grandfather paradox.
In my opinion time travelling is not impossible,but just possible. Yes, my instinct says that time travelling is true and it's present in future and just because of the concept of parallel universe they are travelling into another universe whose timeline is in phase with ours but it's not ours. 😀. Yes it may also be considered that only future travel is possible.

but if the energy used is some thing which is called the dark energy

which is very clearly explained in the my previous link this is possible

I don't have in-depth knowledge in this stuff but I would like to ask a question. What about the "god particle"?. I remember that they are massless particles which is ubiquitous and gives mass to others, so what about their velocity? What if they can be used to reduce the mass given to the neutrinos such that it's speed is increased way above the speed of light? Just a stupid doubt.

Hmm. Higgs Boson imparts mass to particles in the manner of resistance. If there is no mass, there is no resistance, which should mean it will be in motion or travel forever (Zero Friction). Now, I'm no Physics graduate but this is what I gather.

I am not much of a traveller. Though as part of my work, I have had to go all over the world. I am deeply thankful that time travel seems to be like perpetual motion.
AKD's tiltle for the thread has to be considered seriously. If time travel were ever (even in the distant future) possible, why have we not been visited by our great great grand children?
One thing to be kept in mind is that such a machine travels in time, not space. So let us do a thought experiment. Pretend that the chair we are now sitting on is a time machine. Let us travel just one second into the past. We will still be on the chair in front of the computer because the time machine does not travel in space. The monitor should show a time one second less.

Right? May be not.

The earth rotates at nearly 1600 km/hr near the equator. The chair would have moved about 400 m in that one second (along with the rest of the earth). The earth would have moved about 30 km in its orbit around the sun. The sun would have moved about 250 km in its orbit around the centre of the milky way. The milky way itself would have moved about 600 km in its travel.
So in that one second the chair (with us) would have gone about 900 km ahead of where it was one second back, leaving the rest of the world intact.

The implication of this is that even if time travel happens, one can never find anything of the old life.

While this is all very interesting, here are some papers about Bosons and the LHC experiments.

one basic question:

even if the time machine was to be invented right at this moment , then how would you go about doing it ?

but then, even if a time machine was created , the concept of time and age would be destroyed.

if this machine, enables us to go back to the past, than births and deaths can always be prevented, and thus life would become monotonous.

I think their age would be freezed when you travel at the speed of light. i.e. you would not age at all when you time travel. Ah, I remember this one, it's called twin paradox.

In reference to this post and what @#-Link-Snipped-# and @#-Link-Snipped-# has written in the replies -

Time is something the conscious mind creates to make sense of itself. Otherwise, there is no time. There is only now.
I've read a theory that if a time machine is invented in the future then we will only be able to travel back as far as the exact moment it was switched on. I can't remember the whole thing but it ended up getting quite scientific, also it would explain why we know of no time travelers yet.
Anyone here read about it?

What do CEans think?

May be time travelling to past is not invented yet in the future.😨
Because,atleast there are scientific (may become possible) theories to time travel to future.(like increasing the speed of a train or anything to the speed of light , we can travel to future).
But when we want to know about travelling back in time , we always stuck up at paradoxes or wormholes or cosmic strings (which are all imaginary and unstable theories).May be that's why there are no visitors from future.😕

And guess who witnesses it?! The hero's child version!! "Does the child grow up, get sent back in time n die again so that loop continues" was the topic of discussion.

Guess, what it means is If we do get sent back in time, nothing can be changed; it would end up more like watching a movie, only that these will be moments from history. Else grandfather's paradox cannot be avoided.

Time travel avoids grandfather paradox. Well, that's pretty much logical. Because when we time travel, we follow alternative timeline concept in which when you change the past, you create an alternative history not change your own(like what they show in movies).
Unless you're not able to connect two different timelines (i.e original one & alternative one) to our present (present timeline) (using some kinda portal, i guess), it's fail.

Which means you surely can't change the present timeline, but yeah you can time travel to past & give another alternative ending. But that can only be done if you can connect both the timelines.

Dang, this is crazy!

There are more ramifications to time travel. What is the speed of time travel? How long does it take to travel back one year? Another year, an hour, a second or instantaneous?
The other more serious issue is that the time machine is not travelling in space. Even assuming an instantaneous movement of say one year in time, the traveller has covered a lot of distance (along with the earth) in that one year. The poor mutt will find himself that he is way, way off from the earth of one year back.
What is more, how do we know that nothing else is occupying that space a year back? If something else, say another heavenly body, was in that location what would happen to the time machine?

With relativistic time dilation, assuming the time machine is traveling at the speed of light, the clocks would stagnate with reference to any external observer, and as such no matter how far you want to travel back in time, you (as a traveler) would always reach there instantly. As an external observer, you will appear to travel for as many years as you want to travel BACK in time. You will not feel the difference in you clock ticking as a traveler of the time machine, for you everything will be exactly the same as it was before getting on to the time machine, just that you would reach everywhere before your clock can make a move.

Refer "Time Dilation".

That is the nub. In the Einsteinian mechanics, there is time dilation, length compression (only in the dimension of movement) and mass increase. Since speed of light is the limit in this, time comes to a stand still at c, which means the traveler is always in the present.
I do not believe that going >c is possible. So negative time, that is going to the past, is unlikely. Assuming that it were, then there would be a rate of such regression, which may well be defined (not necessarily) by an equation similar to the time dilation one of Einstein.
Traveling to the future is a no brainer. All of us are doing that right now. From 1939 I have come to 2014. However, it is a one way street. I cannot go back to 1939.

Well, since a time machine essentially has to travel at speeds > c (which I romantically believe is possible), I must say that it is hard to believe that time regression would follow lesser dilation at speeds > c than it did at speed = c. That is, if time freezes at c, I think (I can be wrong) it will stay frozen at speeds > c. That's why I said, if traveling to the past in a time machine, the traveler will reach instantly. But that is a very good point, one I did not give much attention until you mentioned, the dilation/non-dilation of time at speeds > c.

As for travel to the future, I totally agree with you.

Shashank Moghe

You are right in that time for the traveler stops at c.
The dilation factor is:
[IMG]

When v=c gamma becomes 1/(1-1)^0.5 which is infinity.
This is the Lorentz factor.
Since nothing can be more than infinity time cannot become negative.
If v>c, we get a square root of a negative quantity, which is imaginary.
Unless there is some other relationship for time dilation if v>c, which is not known as of now.

We have allowed ourselves to be blinded by all this for a very looong time. It is time we realize there is only one god - Love.
