Its 2014 already , neither did any guy from hollywood 70's movie came today from a big muscle car with geeky stuff which apparently made the car travel TIME . Nor did any cyborg or a fancy man from future with fancy suit and a J.A.R.V.I.S type AI taking commands from him come.
What i am wondering is ! Did we ever travel in time? or Will we ever travel in time , be it future or past
If time travel was possible why dont we have people from future or past visiting us right now? i would not mind an artificial intelligence from future explaining me how 11 dimensions actually exist while i sip this cup of coffee right now . But here, i am alone .
There are two possibilities if time travel
1. travel back in past
2. travel to future
1. travel back in past
2. travel to future
Famous physicist Stephen Hawkings has some problems with traveling in past and thinks its near impossibility to travel to past. He says that would have energy from present loop between past and back to present thus causing a feedback loop and energy keeps on adding every loop it takes in past-present and thus making the portal or something similar through which we travel time unstable and ultimately destroy itself. So traveling in past would be as disastrous as bungee jumping without a rope!!
On the other hand traveling to future seems pretty simple , All we have to do is move faster! No no japan's 514 kmph bullet train wont suffice. We need something that rotates earth 7 times a second!!! Near light speed! If you rotate earth for a week's time at this speed now , you will step out in future 2214 A.D.
Developing something that reaches that speed itself is a bigger challenge .
We could harvest such a energy source to power us to higher speeds to achieve these in future. There is another way which is too fancy to believe to travel time - Gravity . If you want to make your clock tick slow than mine just increase the gravity around you and ta-da your minute might be a year for me. Its a known fact for quite sometime that Black holes tend to nurture such tremendous amount of gravity , so strong not even light escapes it . So orbiting a black hole would slow you down to a greater extent that would actually cause you to travel to future. This evidently is whats called a twins paradox
Thus blazing speed or a extremely large gravity would do it for us.
