Wrap your head around this.


Time travel is impossible as exemplified by the famous grandfather paradox. Imagine you build a time machine. It is possible for you to travel back in time, meet your grandfather before he produces any children (i.e. your father/mother) and kill him. Thus, you would not have been born and the time machine would not have been built, a paradox.

Perhaps the craziest of the time travel paradoxes was cooked up by Robert Heinlein in his classic short story "All You Zombies."

A baby girl is mysteriously dropped off at an orphanage in Cleveland in 1945. "Jane" grows up lonely and dejected, not knowing who her parents are, until one day in 1963 she is strangely attracted to a drifter. She falls in love with him. But just when things are finally looking up for Jane, a series of disasters strike. First, she becomes pregnant by the drifter, who then disappears. Second, during the complicated delivery, doctors find that Jane has both sets of sex organs, and to save her life, they are forced to surgically convert "her" to a "him." Finally, a mysterious stranger kidnaps her baby from the delivery room.

Reeling from these disasters, rejected by society, scorned by fate, "he" becomes a drunkard and drifter. Not only has Jane lost her parents and her lover, but he has lost his only child as well. Years later, in 1970, he stumbles into a lonely bar, called Pop's Place, and spills out his pathetic story to an elderly bartender. The sympathetic bartender offers the drifter the chance to avenge the stranger who left her pregnant and abandoned, on the condition that he join the "time travelers corps." Both of them enter a time machine, and the bartender drops off the drifter in 1963. The drifter is strangely attracted to a young orphan woman, who subsequently becomes pregnant.

The bartender then goes forward 9 months, kidnaps the baby girl from the hospital, and drops off the baby in an orphanage back in 1945. Then the bartender drops off the thoroughly confused drifter in 1985, to enlist in the time travelers corps. The drifter eventually gets his life together, becomes a respected and elderly member of the time travelers corps, and then disguises himself as a bartender and has his most difficult mission: a date with destiny, meeting a certain drifter at Pop's Place in 1970.

The question is: Who is Jane's mother, father, grandfather, grand mother, son, daughter, granddaughter, and grandson? The girl, the drifter, and the bartender, of course, are all the same person. These paradoxes can made your head spin, especially if you try to untangle Jane's twisted parentage. If we drawJane's family tree, we find that all the branches are curled inward back on themselves, as in a circle. We come to the astonishing conclusion that she is her own mother and father! She is an entire family tree unto herself.

Amazing short story, the concept of time travel and time itself is so hard to grasp its amazing.

I remember watching the universe and this guy said you can never travel back in time to any date b4 a time machine was made so if one was made may 21st 2008 u could not travel to the dark ages

I don't believe in time in that manner anyways, making the whole matter moot. Its a human sense used to measure change, not an objective force of any sort. When you take that out of the equation, its a matter of circumstance.

Despite all the other problems of time travel, it is not possible for a hermaphrodite to impregnate themselves (even if they had a double).

Problem solved!

time travel would not be a good idea

time travel does'nt exist and will never happen because space & time don't operate that way....keep on believing it though,theres no harm in that. :looking:

I don't think it will ever be able to happen and if it came to be why would you even take the risk of fucking siht up everything happens for a reason

Time travel will never happen. If it could, why haven't we seen anybody from the future?

if you met someone on the street in weird clothes saying they came from the future, would you believe them? would anybody?

if someone were to travel backwards (or forwards, oh god..) in time, maybe they would be careful not to alert any suspicion or notice at all in fear of messing up the 'timeline' by changing things in the past that must happen or else the future from which they come from would be different.. much like the paradox this thread is named after.

I also think time travel is impossible but just on the grounds of me not being able to conceptualize transporting solid matter outside of space, backwards in time, then back into space (or staying in space but just backward in time? bleh)


one of the more interesting ideas ive heard is that martians that have reportedly been seen/captured are humans thousands of years in the future, time travelling back, on some Terminator shit... its wild i know, but it explains why nearly all martians reported being seen are of the humanoid shape, but altered.

also, im pretty sure i heard that stephen hawking said the procedure of time travel is possible, but requires a rediculous amount of energy to produce.. maybe im mixing up who said it, and it could all turn out to be garbage anyway

Hawking said you needed like an infinite amount of energy to achieve light speed, and as of now, that is not possible.

I personally dont think traveling back in time is possible unless it was to the time you built the time machine. But you could conceivably travels ahead into the 'future' because if your traveling at the speed of light, everything else relative to you has slowed down drastically.

I think we are just confused as to how time travel works.

after getting interested by this thread, i looked for a bit on some popular theories..

theres a theoretical physicist right now working on a serious time machine, but his aim is to see if he can transport subatomic particles or messages, not actual humans.. he makes it work by using a high powered laser reflecting back on itself in a cycle, the light (as supported by einstein) can bend empty space around it, and the guy says if he drops a subatomic particle into this spinning empty space (light-speed swirl of empty space) it would leave and come back before it left.. in theory.

the comparison he gave was simple: a cup of coffee (empty space) being stirred by a spoon (light) to create a vortex-type thing, then dropping a coffee bean (subatomic particle) into the coffee and seeing it spin around because of the coffee's intertia.

he says its practical, but requires lots of funding and wont be complete for many many years...

interesting part - he says that right when he activates the time machine for the first time, he might immediately see subatomic particles or messages appear out of nowhere inside the chamber - being the result of an experiment he is still years behind in even starting... which is kinda messed if you think about it because its basically pre-determination, and what were to happen if he recieved the random subatomic particle but abandoned his project afterwards? where would it have come from? parallel universe where he DID continue the project?

crazy shit.

Right, I wouldn't want to mess stuff up either, but I think we can agree that there is no way time travel is ever going to be possible.
