Pi Mesons ...Time Travel proven to be a reality

I have always had an interest in science, evolutionary biology was a big favourite, I enjoyed reading Richard Dawkins as he put it across very well in laymen terms which I would comprehend. The past few years my passion grows especial in astrology, cosmology and physics, especially trying to grasp some sort of understanding in my small brain about theoretical physics and the usual boundaries of science which it transcends. The special and general theory of relativity, quantum physics and leading on to string theory, the more which I read about the more I know I don't understand which drives a thirst to gain more layman knowledge about these things which simply blows my mind. Carlo Rovelli, Einstein, Hawkins, Carl Segan, Neil deGrasse Tyson, Max Tegmark... the list goes on and my home library increases. This month I will be attending Brian Cox's roadshow, a sold out even to see and hear this popular physicist. What I write below is what I have read from Stephen hawking (Reith Lectures and Brief History) and also from the General Theory of Relativity by Albert Einstein but put across in a more accessible way by Micheael Strauss. This just blows my mind.....there is a god and his name is science, if you want to keep that candle lit as you are still scared of the shadows outside your cave and the sound of thunder makes you believe that the gods are angry and you reach for that iron age book of fairy tales then get out of that primitive mindset and pick up Seven Brief Lessons of Physics by Carlo Rovelli or I would especially recommend Carl Segan's Billions and Billions. Time to forget about the restrictions of your brain that religion places, get out your comfort zone and learn about something much more enlightening. Its not an easy journey but every branch of science needs commitment to understand and to learn, like an apprenticeship of learning so you can then appreciate the true masters, open your eyes to the beauty of Einsteins general theory of relativity which can move you as much as Mozart's Requiem or the ceiling of the Sistine chapel. The excitement I feel when I begin to get a grasp of understanding of such concepts and the sheer beauty in them. Here is an example...Time Travel, Back to the Future, looper ....we have seen the movies and its always a novel interest but here is the scientific facts, its now actually been done...in Cein by Pi Mesons yet Pi Mesons are not a household name yet? this has not made front page news? WTF is wrong? don't dumb down any further....get amazon open and buy some science books. Time travel..... Nothing is flat or solid ....if you look closely enough at something you will see holes or wrinkles in it This is easy to see in our 3 dimensions but it's also in our fourth too, there are tiny wrinkles and crevices in time. Time is our fourth dimension. Smaller than atoms we get to the quantum foam, this is where wormholes exist. Constantly disappear and reappear in this quantum world, tiny worm holes through space and time. They link two separate places and two separate times. These real life time tunnels are just a billion trillion trillionth of a centimetre across. Way too small for a human to pass through. Some scientists think it maybe possible to capture one and enlarge it many trillions and trillions of times. There is a time traveling problem of travel to the past, the problem of paradoxes. Causes happen before effect and not the other way around. Use the "mad scientist" paradox as it's such an easy one. A scientist makes a wormhole in his lab, just enough to go back 1 min in time. Once in the future he looks back through this worm hole and he shoots a bullets and kills his past self as the bullet egresses from the worm into a minute into the past where his past self stands at the worm hole. If his past self dies then his past self can not travel through the worm hole to fire the the bullet so who shot the shot? This is a paradox. This violates a rule in the universe that causes happen before effects and never the other way around. Now scientists have concluded that a wormhole life like this can not exist and this is due to "feedback" If you have been to a heavy metal gig in the hydro for example then you will recognise the screeching noise which is "feedback" ...cause by sound entering the microphone, traveling down the wire, made louder by the amplifier then comes out at the speakers but if too much of this sound goes back into the mic then it will go round and round in a loop getting louder each time ....if no one stops it then feedback destroys the sound system. The same thing could I'm theory happen to a worm hole, but with radiation instead of sound. As soon as a worm hole expands, natural radiation would enter it and end up in a loop. The feedback would become so strong it would destroy the worm hole. So although tiny wormholes do exist and perhaps one day one can be inflated, but it won't last long enough to become a time machine. So the conclusion is that any time travel into the past through worm holes (or any other method) is probably impossible. Also if it was possible I would think we would have knew by now from one of many visitors from the future. Now time travel into the future.....that's a different story!!! Time is like a river, it flows at different speeds at different places ....and that is the key to traveling into the future. There are 31 gps satellites orbiting the earth just now.....and they have proved that time runs faster in space than down upon the earth!! Inside each satellite there is a very precise clock, a atomic clock but despite being so accurate the clocks on these satellites all gained about a third of a billionth of a second every day compared to the ones on earth synchronised at the same starting time. There has to be a built in correction mechanism or all the gps devices on earth would go out by about 6 miles a day. Time in space runs faster than time on earth. The cause of this is the mass of the earth, Einstein realised that matter drags on time, slows it down like the slow part of a river. The heavier the object the more it drags on time warping space time (space and time are the same this ...read some Einstein) .....now cue black holes Right in the centre of the Milky Way, 26 thousand light years from the earth lays the heaviest object in the entire galaxy....a super massive black hole containing the mass of 4 million suns crushed down to a single point by its own gravity. A sphere of darkness as no light can escape, the black circle is 15 million miles in diameter. A black hole like this has a dramatic affect on space around it slowing everything down thus making it a natural time machine. If, now this is all theory of course, a space ship approached this black hole, avoiding being sucked into it, aim just offset of it, closely orbiting it carefully not being sucked into it, traveling a giant circle of it, all 30 million miles orbit around. If this was monitored from earth each orbit would be seen (from earth) to take 16 minutes but inside the spaceship time would be much slowed down....by half, for every 16 minute orbit they would only experience 8 minutes of time. Round and round the craft could travel, experiencing half the time of everyone else away from this black hole. The ship and its crew would be traveling through time. So imagine they circle the black hole for five of their years, 10 years would pass elsewhere...when they returned to earth everyone there would have aged five years more than they had. The crew of the space craft would have returned to a future earth. A journey not only made in space but in time too, returning to the earth 5 years in the future. No paradoxes. Considering event horizons (google this) and the gravitational pull of the black hole, the space travel needed to get there which would be going at the cosmic speed limit, the speed of light 186000 miles per hour for 26 thousand years then back to earth again (what would be the evolution of mankind after 52 thousand years in earth or cooped up in a safe craft generation after generation) this way of time travel is a surely must be only theoretical. But there is a "easier" way ..... Build a train track around the world, across the oceans, deserts and land masses, circumnavigating the whole globe. Then get a train traveling with passengers at a speed almost the speed of light as nothing can go faster than this speed, so say 185999 miles per second (the laws of physics prevent it going faster than the speed of light, imagine if a child on the train ran up the aisle of a train traveling at the speed of light, so then that child would be going fast than the speed of light which is against the laws of physics ....no nothing can go faster than the speed of light and within this train time also slows as not to allow this to happen....a law of nature, time will always slow down just enough to not allow anything to break this speed limit) so now this train is circling the earth, on its tracks, going around the globe seven times a second. For the passengers on this train inside, time would slow down. Time would now flow slow on board this train and for its passengers, slow in relevance to the rest of the world. Everything in the train is in slow motion (for reasons I gave previously in brackets, so not to break the natural laws of physics) Imagine this train left the station January 1st 2017, circles the earth at these speeds for 100 years before coming to a halt on New Year's Day 2117. The time passed for the passengers has only been one week as the time has slowed down that much inside the train but when coming out of the train they would find the world 100 years older, 100 years would have passed. The passengers would have traveled 100 years into the future (minus one week which passed for them) they, in effect have traveled into the future!!! I did say this would be an easier way compared to circumnavigating a black hole 26 thousand light years away in a space ship. This is an easier way so now you see the true complications of time travel. You can't imagine a track around the works with a train traveling this speed ....but now think about the what we have built ....the worlds largest particle accelerator at Cein in Switzerland, The Large Hadron Collider!!! Deep underground 16 miles long circular looping tunnel. When the power is turned on the particles accelerate from 0 to 60000 miles per hour in a fraction of a second. Turn up the power and the particles speed up, circulating this 16 miles long loop 11000 times a second ...which is almost the speed of light!!! These particles are traveling in time, as like the passengers in the train time for these particles slows down!!! How do we know this? This is the clever part ...amongst these particles some are a type called pi mesons which are normally short-lived; they disintegrate after mere millionths of a second. But when they are accelerated to nearly the speed of light, their lifetimes expand dramatically. It seems that these particles are traveling in time, or at least experiencing time more slowly relative to other particles if their kind not traveling at speed. Pi Mesons are real life time travellers!!!!!
