Will it ever be possible to go back in time?

What do you think? There have been a lot of developments over the years. Just 100 years ago, you would have been committed for saying that something as seemingly ludicrous and impossible like the internet would ever be invented. So, why do so many just write off time travel as an impossibility?

    A phenomenon called time dilation is the key here. Time passes more slowly the closer you approach the speed of light -- an unbreakable cosmic speed limit. As such, the hands of a clock in a speeding train would move more slowly than those in a stationary clock. The difference would not be humanly noticeable, but when the train pulled back into the station, the two clocks would be off by billionths of a second. If such a train could attain 99.999 percent light speed, only 1 year would pass onboard for every 223 years back at the train station.

    But speed isn't the only factor that affects time. On a much smaller scale, mass also influences time. Time slows down the closer you are to the center of a massive object.

    Time runs a little bit faster in space than it does down on Earth, It runs a little faster on the roof than it does in the basement, and that's a measurable effect

    A clock aboard an orbiting satellite experiences time dilation due to both the speed of its orbit and its greater distance from the center of Earth's gravity.

    Both gravity and speed can give you a means of jumping ahead, So in principle, if you had enough money, you could get to the year 3000 in as short a time as you like -- one year, one month, whatever it takes. It is only a question of money and engineering."

    Forward, not back?

    Time travel into the future is an established and fundamental aspect of Albert Einstein's theory of relativity. Scientists have tested and retested this in both experimental and practical settings. But what about time travel in the opposite direction?

    Going back in to the past is a whole different kettle of fish.There's nothing in Einstein's theory, which is the best theory that we have about the nature of time, which precludes it. There's nothing in even his general theory of relativity, published in 1915, which precludes travel back into the past, but many scientists are deeply uneasy about it because of all the well-known paradoxes that it unleashes

    For instance, imagine going back in time and killing your own mother. Then she'd never give birth to you, and just how would you have been able to travel back in time to commit matricide in the first place?

    I doubt travelling to the past will ever be possible.

    However I think time travel to the future will, in a way, be possible one day.

    I'm not the best at explaining, but if we could design spaceships to travel VERY fast, then time passing for the people on board the ship is slower IN RELATION to time passing on Earth. So (if travelling fast enough) after 20 years travelling in space 40 years may actually have passed on Earth. While the people have only aged 20 years, their family and friends have all aged 40 years. Although everyone on Earth lives life normally, for the people on board the ship it will feel as if they have travelled into the future. It's a confusing concept. The show "Into the Universe with Stephen Hawking" explains it very well with trippy visuals. (episode name "Time Travel")

    Yeah if u just could move faster than light , but anyway if u could u would just SEE things in the past but can't actually be there, like what they do in "Soul Travelling".

    Yes. You would need to build a craft out of anti-mater. Wear a space suit made out of exotic mater so that you are not killed, and ride the ship backwards in time. The trick is building a ship out of anti-mater because it wants to travel in the direction of anti-time, aka backwards in time, which makes assembling it very difficult.

    no no no no no NO !! Going back in time is impossible. One definition of time is "an illusion created by motion" (Ron Hubbard). Time in fact only exists as a subjective perception dependent upon motion, and motion is described as one of two alternatives, either "stop" or "go". In other words energy is expressed as either motion or no motion. Emitted and radiant Energy itself moves in only one direction fundamentally and since time is a function of motion it therefore follows that time moves in one direction only... ie.. "forward".

    However, it IS possible to travel FORWARD in time, as I explain in my book... the univerese kindly permits this , but time travel in any event requires a lot of energy since we are referring to the distortions of space and time, (like in a black hole). Not as much energy as this is required , however .
