Probably on how we define time travel.

Based on time dilation,
If my inertial frame were to experience time dilation, where my inertial "clock" move slower, the observers flow of time would have gone past me.
Let the observers time frame would be hypothetically t=2000s where as in my time frame it would only be t=1500s both relative to the "True clock" or "start of event"
To myself, my time frame would be the "true" timeframe. I see the observer as something that have yet to exist on my time frame, something that is aged t=2000s. But only 1500s has passed in my time frame. Hence i can conclude that i have "traveled" to the future.
To the observer, i am "younger" than i should be. I have "aged" only 1500s where as their "clock" shows that it is t=2000s. Hence, they can conclude that i have travelled from the past.
Isn't this in essence the "time travelling" that is hyped about?

Evidence is quite clear on how the subatomic particle,muon which has a lifespan in nanoseconds before it decays, reaches the earth's surface from the upper atmosphere. Even if it travels at the speed of light, it wouldn't have been able to reach earth's surface based on its lifespan yet we are able detect them at our surface.


Though, special relativity and time dilation explains only going forward in time.

Going back in time however, some theories suggest that a massive enough object is able to curve space time so greatly that if we are able to "jump" the void caused by the curvature, we will reach a point in spacetime where the actual flow of time has yet to arrive. Black hole as THE possible massive object?. Though this is general relativity which requires maths which i can't even understand, to well .. understand it.



PS. strictly on time travel. Paradoxes are situations based on us as humans. Since if humans approach c, we will lose almost all of our mass and turn into energy Though i have used human descriptive, specifically those in " " as it is easier to understand

In terms of human time traveling probably. As far as scientific theory and real life application, it is already happening and used in today's techonology (GPS satellites).

Though it also depends on how you define time travel. An analogy i made based on the maths of time dilation is in one of the post above.

Obviously you didn't bother to read the posts that are here in this thread.

Curvature of spacetime and time dilation is a proven theory. Go read up on it



That is basically e=mc^2

When you reach the speed of light, your mass becomes energy.

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.

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.

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 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



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.

Please read the previous posts in the thread.

Hmm, i never thought of it this way. Perhaps if we can create a machine to view a certain event, certainly much more feasible than a machine to take us physically there. This could find good use in forensics
