That is because time on earth is a relative value rather than a constant one. That is why we have 24 time zone on earth instead of just one.

Eg. A malaysian's 12pm is a New Yorker's 12am at the same point of time, while that same point of time is constant throughout the universe ever since the beginning of well. Time.

I personally believe time travel do not exist, all the existing time paradoxes sum up my argument.

My biggest doubt is traveling back into the past. A governing body that control time travel strictly? It will only take one single rogue time traveler to go back in past, causing event with powerful butterfly effect and create all kind of chaos.

With an infinite future, are there any guarantee that nobody else but the governing body develop time machine that's capable of traveling to the past? North Korea developed nuclear weapons too you know so what's there to stop countries that aren't on agreeable term with time traveling administrations bodies developing time machine and using them?

Time slowing down through high speed while proven possible but it's more of an illusion.

An astronaut slowed down 5 years of his time out of normal earth 10 years for eg.

So if he say, started his speedy journey at 2010, while he only aged 5 years, he still returns to Earth at the year 2020 not 2015. Since time is a relative value, it does give the illusion he traveled through time into 5 years ahead.

Don't believe in movie and shows Paradox and theory of time travel apply subjectively.

Take Terminator franchise. It is good example of time travel that defies paradox subjectively, meaning one person's paradox is applied while the other don't suffer from the effect.

In T1, the remains of Terminator were later used as research by Cyberdyne to lay the foundation for Skynet and other killing machines. The Terminator is from the future, so it becomes a loop with no beginning nor end, chicken and egg paradox.

John Connor wouldn't exist without Kyle Reese, and Kyle Reese wouldn't be sent back without John Connor. Another loop.

John Connor would have know that Skynet wasn't defeated when T2 ends. If Skynet cease to exist after he throws the chip and arm stolen from Cyberdyne into the molten steel. Why didn't the T-1000 vanishes? It won't take T3 to let John knows that Judgement Day is still there.


Time is actually a unit to calculate durations that's why it's relative (24 hour time zone thing) But, what is 'duration' then? They aren't made out of matters in the visible 3 dimension. It is said this 'duration' made up another invisible dimension that we couldn't see with conventional means. This is the place where time runs at a constant rate.

Do note that science beyond the 3 dimension is still an ongoing research(String Theory, The Theory of Everything), if I'd figured out to discuss it further I would've won a Nobel Prize already

Your father killing scenario has a paradox as well.

You kill his father, he wouldn't exist, why would you hate him? He doesn't exist! So what's drives you to go back in time and kill his father?

This is why I believe time travel doesn't exist.

The paradoxes I've mentioned are very related to issue with time travel. Even if you're able to travel back in time, you have to overcome these paradoxes, or you'll be traveling into an alternate universe that have an entire set of scientific laws that nullifies the logic of mentioned paradoxes. I won't count jumping universe as time travel because you're no longer influencing the universe you are from, but rather in another universe.

There's theories that the universe we live in keep duplicating itself everytime a single 'tick' of universe time is passed. These duplicates are infinite that they account for every possible outcome of certain event in the universe. Quantum physic stuff if I am not mistaken

Eg. If you rolled 2 dice, there can be 37 outcome, so at the moment you roll the dice, your universe will be duplicated 36 times for a total of 37 different outcome(36 plus the one you're currently in).

Time travel is not only theory, but it's actually happening. We're traveling into the future 1 second at a time what

The question now is can be manipulate that constant flow of time that we can move back and forth at any point of time in space?

I still think no

Observing time traveler? Whee! We blew billions to create the universe's biggest history book

If the universe is predestined, you won't be traveling back in time, even as an observer. What you observe in the past may alter your present perception that will alter your future action. So if it's predestined, you shouldn't be changing your mind after reading what's in the past because that will alter the future.

In a predestined universe, Hitler will never get killed but WWII would still happen. It's contradicting because, if WWII were to still happen because it's being 'predestined'. Hitler would be predestined not to die as well

Actually no, space is full of space dust. At the speed of light, hitting a single sub atom is like the entire Jupiter slamming your body.

Outer space isn't actually void of nothing. If you travel beyond the border of universe, the empty 'space' is actually something. So it's sort of a perspective issue

Ahh, yes, I semi-misunderstood you on the friction thing. There's no air in space

Particles of space dust as small as hydrogen still exist however. If you're going fast enough to pass through lots of these particles, their cumulative force resistance is enough to drag you down just like air

It still doesn't stop rogue members/agencies from using it for illicit/unsanctioned action. Unless you're sending robots back in time, but what are the guarantee that it will not malfunction or has Trojan code in it's programming?

Codes of conduct only look good on paper, practical wise it's a terrible way to enforce law and order.

Nothing to back up what you've said, now that's what I call nonsense

Seems like the only garbage in this thread so far is from you

Come on, say something to back up your 'logic thinking' that time travel is nonsense.

Time is another dimension after the 3 dimension of perception, it's not something that you can store on tape/DVD or any other medium(at least for now). Just like you can't store width, length nor volume, sounds funny that volume can't be stored, but it's true, even if you put water in a container, but it still occupies the same amount of three dimensional space, only when you 'hold' water in an alternate dimension then you can truly say you contained a dimension.


Nobody has been able to exceed the speed of light, at least not that I know of, so we work on the assumption that the cosmic speed limit is the speed of light, about 186,282 miles per second.

If you were traveling on a spaceship with 2 cabins going at 186280 mph, and you need to go from one cabin to another(say Cabin A to B), and you rode a Segway to do it, at 20mph. Now if you add both you will realize it exceed the speed of light, so space-time get distorted around you and slows you down so that you obey the speed of light. From your perception, you're still riding a Segway to Cabin B at 20mph, but if an observer is able to travel alongside your spaceship and see you moving, you'll only be traveling at 2mph(since you're 18mph over the speed limit of light).

So if you took 2 minutes to get from Cabin A to B, from your perception, from the observer you actually took 20 minutes, technically you traveled to the future 10 times the time you spent on the journey. So in a way you can travel through time at sheer speed. You don't have to look very far to see the effect of this so-called 'time dilation'. Clocks on space shuttle missions always return to Earth out of sync(very very minute difference, like millionths of seconds), and GPS satellite has to resync themselves often else they'll throw you off course by feets everyday.

Well if you read back from page 1 I did gave my opinion that time travel through some form of material transfer is impossible, due to the looping paradoxes, at least into the past anyway. Time dilation is closest you can get to time travel, and under the assumption that nobody can go beyond the speed of light, we do not know if traveling faster than speed of light will reverse time.

Come to think of it, with 6.4 billions humans on earth now, what are the odds of every single time travel agent from the future being tight lipped, or not exposed by present time people?
