MERGED: Is time travel possible?

u guys ok right? just checkin..

[edgeknife]

sa salida ra ni like back to the future ni michael j. fox. pero sa actual, dili ko mo tuo.

[silent-kill]

matod pa sa quantom physics...

kong ang taw mo travel mas paspas pa sa speed of light... iyang 1 second would end longer... sa usa ka observer..
therefore.. ig balik niya sa kalibotan.. mas bata pa siya compare sa mga tao nga iyang gi biya-an hehee...

naa pud toi theory about wormholes and time travel...
ang akong na kit-an is padong ra sa future... wala pamay concept padong sa past... kai na hitabo naman ang pass gud heeh.

time travel is cool. but the question is are we traveling through time or dimensions? there is an idea than in every possibile actions we do in a certain time opens up a series of different worlds. For example, in a span of three seconds you have over a million or plus of possible things to do in that span of time, like hop, close your eyes, jump, sit, stretch etc... you cant choose all of them at the same time, each possible action is a world in its own, once you choose an action, you choose a world, all other discarded possible actions may not exist in our world, but each possible actions discarded becomes a world of its own. so when i have finally chosen to type this, and i have discarded the other possible actions of watching tv, reading a book, jumping, there are other thechild(s) doing those other alternatives in different parallel worlds. i forgot the theory, its weird, more like fiction than real theoretical science, it is close with the mutliverses theory, but i cant really pinpoint. Once we do time travel, the question is are we traveling in our dimension or another dimension? is it really the past? or is the present, is it really us in the past using our present time as reference or is something else? general relativity no point of reference. and again its weird, hey but its cool! questions like this makes the "time travel" a misnomer.
but hey, im not physics student, im only upto empty speculations. but it would really be cool to travel back and mess up the primordial soup.

it would be totally cool if we get to see our ancestors thou.... but.. nope.... not possible...

[makoyvelasco]

maybe yes, maybe no. wa lang gyud ta kahibalo. just like computers. years ago, we thought computers would be impossible, yet look at it now, almost everybody has computers. it might take time, but eventually, this would come into reality. who knows

[Silver_Surfer]

hehehe, kung tinood palang jud ni, i want to see my great grand ancestors...

Time moves but it doesn't have a space where we can travel back and forth. Time has a very short lifespan, the moment it is here is the moment it is gone. No physical traces left except evidences (nail growing, ageing etc.) that it ever was here.

I think I would agree with The_Child. If indeed we are able to travel through time, it might just be a parallel universe we are treading in.

If the world was a super computer (a la Douglas Adams in Hitchiker's Guide To The Galaxy), then it might be possible to view our history. But that's about all that we can do. Just view it and maybe experience it in 3D. Cool!

adto mos pasil naay daghan time machine didto

i hope naay maka invent jd ana woe..
