OT: Ooops my bad, I checked all three pages of Science Board but I must have overlooked this already existing thread. Thanks.

lol. im here trying to explain time travel.

trying to understand e=mc2 and theory of relativity but it just made me feel stupid.

anyways, here's my 2cents.

according to einstein, if we travel at the speed of light then we may travel with time (if we go faster then we travel back).
hmm... im only traveling at the speed of 40-60kph going to work.
kung mag commute ko, it would take me about 1hr.
pero kung mag motor ko, it only takes me 30mins.

i guess time travel is already happening there, huh?

anyway, lets continue...
kung naa lang teleporter (like that of the star trek), im sure i would arrive in the office in less than 1sec.

now, if we have the teleporter technology working.
we need 2 teleporters, the origin and destination.
example - teleporter(office) and Teleporter(home)

if i can set the teleporter(home) to constantly travel at the speed of light, thereby it's traveling with time. I could use the teleporter(office) to travel back to home, i should be back in that time.
otherwise, we cant travel back further more in history.

it's in genius! Im mojo jojo! you will obey my commands!

another one - i got this from eric cartman.

freeze yourself today. unfreeze yourself tomorrow.
Instant time travel, see? so simple.

This was exactly my point re the "comatose person who woke up 30 years later" type of cases. For them, they have indeed travelled to the future.

i dont think so, i dont think that could be called time traveling..

That's because you're used to the idea that to "travel" means a spatial, rather than a temporal shift/change.

actually i was thinking both but i dont think that idea can be called time traveling still.. well on my POV to do such thing the theory of speed of light will be utilized which only means one thing you can outrun time or vise versa when you do reverse time traveling if possible..

comatose state is not utilizing the theory of light in fact it's just flowing at the same time stream through which means normal lang ang passing of time..

You seem to be under the impression that time has a certain "flow", of having a "normal" flow and some other type of flow, when in reality, time flows only in one direction, as indicated by this diagram.



The reason why we perceive time to be "running slow" or "running fast" is only an offshoot of where the observer is located in space, and here is where one's understanding of relativity (specifically, the special theory of relativity) comes in. If we were riding a rocket ship that is travelling at 99.9% the speed of light, time outside the ship would appear to pass by quickly as we look outside, yet for someone watching the rocket, it would seem as if the people inside the ship are aging very slowly.

hmmmmmmm i think i get the point, well you can say we are traveling trough time right now though..

just as i thought time traveling is simply waiting time to pass by and not to out run time..nyahaha kita raman cguro giilad ani.. but still im open to new ideas which are interesting who knows we might out run time in the future well if thats possible..hehe

Yes, very good points. We are indeed travelling through space-time at the moment. We may be sitting still in our chairs, but the Earth itself is rotating AND also moving through space, and the Sun is moving amongst the stars, while moving around the Milky Way, and the Milky Way itself is also moving. All that time, time is also flowing forward. Thus, space and time are interwoven.
