I LOVE BACK TO THE FUTURE.. it'll be great if i can alter/prevent some mistakes in my life.. but without these mistakes, i wont be where i am today. Mistakes are my teacher in life. but anyway, our lives are intertwined, if anyone i'm close to, went back to the past and change something, wont it affect my present life too? Time's a subjective space, very hard to define the exact location, time, date and space that you want to go back to. Our technology must be really sophisticated and accurate to have the ability to transport us back. Maybe 300 years later?
In the near future, however, man will be able to teleport themselves from place to place. I watched a documentary somwhere about teleporting and in recent years, physicists has successfully teleport atoms.. i think teleporting are more useful than travelling back to the past.. ^^
TELEPORTING is another form of time transport.it shifts time..like a deck of cards....u get the entire card and take it out n place it in a certain place in a deck of cards.
would u shift the card by cutting it into its atomic state???n piecing it together later on????
i think its all done whole n not piecing stuff atom by atom.
The problem with time travel is why the future people never travel back to see us.
I think time travel is impossible.
Maybe this will help..
The actual teleportation is a big scanner that people go in and every one of their atoms is scanned, type (H², C, O², O³), and their exact position. A modern
computer sends the info to the destiny computer and it makes a person from a barrel of oil by changing its atoms form and position.
Scientists can only teleport a few atoms
these days, and anyway, there would be a problem. The person that goes
into the scanner has to be scanned and disintegrated very quickly,
otherwise the person would die in the middle of the process. And even if
it is quick, after the disintegration, the person is dead, and another
person exactly like the one that died appears in the destiny with the
exact same memories, but it still wouldn’t be the same person, she
wouldn’t be able to tell if it’s her or not.
Originally posted by Hitman 2010:Because astronauts like the ones on the International Space Station (ISS) are moving so quickly, they're also aging a bit more slowly than the rest of us. Due to a principle of physics known as time dilation, after a six-month stint on the ISS, returning astronauts are just a tiny bit younger than the rest of us. But before you book a ticket that'll take you literally out of this world, understand this isn't exactly a fountain of youth we're talking about. Your six-month effort at age reduction will only garner you about 0.007 seconds of extra life, according to the calculations of one ISS astronaut [source: Lu].
But that's not really the issue we're talking about when we discuss how humans age in space. Let's start with a rundown of how the aging process typically proceeds on Earth. Until scientists muster up a way to make us all immortal, most of us will go through the process of aging. This typically involves metamorphoses like bones becoming brittle, blood vessels hardening, muscles wasting away, joints stiffening up, bowels turning irritable, bladders becoming unpredictable, teeth decaying, vision growing dim, skin wrinkling up, and so on.
While for most people, it takes decades to really start to feel the effects of the aging process, humans stationed in space experience some of them in fast-forward. They're often reversible once an astronaut returns home, although sometimes a few of the changes can be permanent.

A lack of gravity is the main cause for these intense alterations. Gravity is one of the most important forces at work on Earth, and it plays an immense role in the majority of our bodily systems. Take the muscles, for example. Older peoples' muscles tend to shrink and atrophy as they age and become less mobile. Astronauts' muscles react in a similar way because they are barely used. That's why astronauts in space for extended periods of time use special exercise machines to help mitigate this effect.
A similar process takes place in the bones. After a certain age, people on Earth start to lose mass in their bones, typically at a rate of about 1-to-2 percent a year. But in space, those people lose bone mass at a greatly accelerated rate: as much as 1-to-2 percent a month. Because the astronauts' skeletal systems don't need to support their weight, the bones begin to decrease production of new bone material and increase the amount of old bone absorption. Luckily, their skeletal systems usually return to normal once they've spent some time back on terra firma [source: NASA].
Even though they're saving 0.007 seconds, astronauts still experience some of the symptoms of a drawn-out aging process. Researchers are working to figure out the mechanics of why these changes occur, as well as what can be done to prevent them. This information could not only to help make spaceflight easier on the human body, but to help improve life on Earth as well.
Space tourism is possible
Haha, yeah! i also wanna visit space and probably get to know ET ^^
.....folks, there are so many wonderful places in the world to discover in the present moment, why go time travel to seek out things that were already over and done with? Keep the happy memories and look forward to the future.
i watch a lot of documentary about time travel. it is entirely plausible, but as of now, it is impobable. technology needs another few hundred years.
