   I want to know if time traveling is possible?I read an article on BBC site.It said that one may go back in past but can't change anything from the past.Where did this concept come from?

      According to Einstein, time travel is possible. Acceding the speed of light is observed in galaxies furthest from our own, which suggests that they could, in theory, be breaking the time barrier, if that is what time is. Time is relative to your position, it passes different for someone in a moving vehicle, backing up my assertion that cars are merely slow moving time machines. They don't change space, but the time it takes to move from point A to point B. The time paradox is stated most simply, like this: If you went into the past and killed your father in his crib, then you wouldn't have been born, so, therefore, could not have traveled into the past to kill your father.

         I don't think Einstein actually made that claim, but others have used his field equations to theorize such.
         
         
         
         The galaxies themselves do not move faster than the speed of light, this is misleading. It is the space between galaxies that is expanding which is calculated together over great distances within our co-moving coordinate system. Space itself is a vacuum and does not violate the physical laws both matter and energy are bounded within the coordinate system.

         Ahhhh the old 'Grandfather Paradox' which is a popular theory in Sci-Fi film and novel fiction.
         
         The Grandfather paradox relates to if you went back in time and killed (accidentally or on purpose) your grandfather before your father was born, you effectively cease the existence of your father, therefore yourself. To get around this, since you are still 'existing', you in fact create a parallel time line, therefore in THAT time line, you do not exist.
         
         Then and this is what really bakes the cookies, would you indeed be still on your own timeline or a third timeline, if you were to return to your own future one pico-second after you left to go to the past (to kill your grandfather).
         
         Its all theory and conjecture.

      Quantum Physics.  Which currently is disproving some of Newton's law of physics. 
      
      But it has nothing to do with Metaphysics, Meditation, Astrology and everything to do with Quantum Physics.   
      
      In Quantum Physics, they have proved that a person can be in two places at once, and that a person can be alive and dead at the same time.  Really mind blowing stuff.   
      
      Einstein proved that as you approach the speed of light, time slows down.

         He did not prove that, he theorized that with Special Relativity using Maxwell's equations. If it is you who is traveling at near light speeds, your clock appears to be ticking normally while it is the clocks you would observe that are not moving at those speeds slows down.

      John Glenn division of NASA here in Cleveland Ohio is working on the project of breaking the speed-of-light barrier and perhaps with it, the key to time travel - or not. Thus far, data is that speed of light can increase. Check out sites  obscure.org/physics-faq and astro.ucla.edu for more changes to that constant.
      
      Cheers.

         What? I would be very suspect about a claim like that from NASA. Do you have a link? I could find nothing on it.
         
         
         
         I saw nothing in those links that supports that claim. Can you be more specific, please?

         If they manage to achieve that, then first thing these scientist will discover is speeding the flow of electrons (which is current barrier for developing highest possible speed for any processor to speed say 4ghz or 5ghz which no commercial processor company achieved yet). If speed of light can be increased then surely the processors can gain performance boost as well. Okay my point was, giving boost to light and boosting flow of electrons both are quite related.

   The very first time travel machine was created in the 80's, a senior scientist and his apprentice designed a car but since then the technology has come on leaps and bounds.. Trouble is the government is charging a large fortune for anyone who requires this ability.

   It is said that time doesnt come or go.meaning the past and future are always there,with the present.we can switch to any time.Its like a long road.when you are walking on it u cant see it much further but it does nt mean that it is not there.

   Michael Crichton wrote Timeline back in the 1990's which involves quataum physics and time travel. It's one of my favorites written by him. He also had a background in the medical sciences having graduated from Harvard Medical School.

         I'm not certain, but I don't believe so as he started writing while in medical school (Andromeda Strain). after he graduated, he was involved in a fellowship study at Jonas Salk Institute for Biology. So many of his books are in some way related to science. It was sad when he died, such a remarkable man. at least we have his books and his many essays. http://www.michaelcrichton.net/aboutmic … raphy.html

   Time is not linear. It's all happening at the same time. It's just that our minds have learned to look at it as past, present, and future. We don't know how to use our brains to its full capacity, but if we could we would see that everything that we consider our reality in nothing but an illusion.

   I know this is reaching but they, being certain secret govt. officials around the world say, and these abductions by aliens say the aliens are doing it. It makes some sense if ExtraTerrestrials can travel at 5,000 miles per second according to some comm'l and military pilots.
   Why not? if they can get here and we can't get to their universe, why wouldn't they know and use quantum physics.
