Closer To Truth: Is Time Travel Possible?

There is AN current PBS TV series (also many books and conjointly a website) referred to as “Closer To Truth”. it’s hosted by neurobiologist Henry M. Robert Lawrence chemist. he is featured in one-on-one interviews and panel discussions with the cream of the cream of today’s cosmologists, physicists, philosophers, theologians, psychologists, etc. on all of the massive queries encompassing a triad of broad topics – Cosmos; Consciousness; God. The triad together restrained reality, house and time, mind and consciousness, aliens, theology and on and on and on. Here area unit many of my comments on one among the final topics lined – Is time travel possible?

# Is time travel possible? truly I in person do not believe time exists. amendment exists, and time is simply our mensuration of rate of amendment. IMHO time is simply a thought. Time could be a mental construct that helps America come back to terms with amendment. Some cosmologists say that point was created at the massive Bang, as if time were a issue with substance and structure, however I challenge them to really produce a while ahead of their peers or even a viewing audience or a minimum of manufacture a theoretical equation or 2 that might produce time. within the meanwhile, here’s a triad of points.

First, the idea of your time travel is one among those fun components of physics. whether or not true or not, it’s amusive to play the ‘what if’ game. If nothing else, the idea makes or forces one to have confidence the character of reality.

Secondly, Einstein et al. have postulated that point travel could be a theoretical reality and i am not in their type of league that I will dispute the theories. i am going to leave that to others World Health Organization apprehend the sector within and out.

But third, and most significantly, you’ll ne’er truly be within the future or the past, solely within the future or the past compared to wherever and after you area unit currently. In different words, regardless of however you slice and dice things, you exist within the where-ever and within the whenever in this where-ever’s or whenever’s currently or in different words within the gift. you can’t virtually be in any future or in any past since you merely expertise the currently that is that the gift. If you must somehow travel back one hour, you’d still expertise things as happiness to currently. If you sleep for one hour then come to life, you’re within the future relative to after you visited sleep, however you continue to end up within the currently.

# Is time travel possible? the solution is each affirmative and no. Yes, we will travel into the long run at one second per second, we tend to try this anyway whether or not we tend to am passionate about it or not. affirmative we will travel into the long run at a rather faster rate by attending to sleep or otherwise having our sense of consciousness, our awareness of rate of amendment (which is what time very is or measures) incapacitated. You get drunk and pass out and also the next issue you recognize you’re twelve hours into the long run. affirmative we will travel into the long run as made public by Einstein’s twin ‘paradox’ wherever one twin travels at a really high rate of speed outward certain, stops and returns to home base, whereas the reside home twin, well, stays home. Upon their reunion the move twin finds their reside home twin to be way older, therefore the move twin has cosmopolitan into the long run quicker than would otherwise are the case. Yes, you’ll travel back in time, in theory, per the apparent theoretical properties that wormholes or black holes will have. No, you cannot visit the past owing to all of these nasty paradoxes. i prefer the variation on the gramps contradiction in terms whereby you travel back only one hour into the past and shoot yourself dead. that is a completely unique means of committing suicide! the opposite contradiction in terms i prefer is after you return in time to own Shakspere autograph your copy of “Hamlet”. Shakspere is not home however the maid guarantees to own him autograph your book once he returns. Alas, your temporal arrangement is slightly off and Shakspere hasn’t however written “Hamlet”, thus once he receives your copy from his maid to autograph, he reads it, and once come|you come back|you come} to Shakespeare’s home and receive back your currently signed copy and return home to your own time, Shakspere currently writes “Hamlet”. The contradiction in terms is, wherever did “Hamlet” come back from since Shakspere solely wrote it once he had already seen your copy. No, you cannot travel back to the past as a result of if that were potential there would be hoards of time-travelling tourists World Health Organization went back in time to witness some vital historical event or different. No hoards of photo-snapping tourists have ever been documented being gift at Custer’s Last Stand, the Battle of the massacre, the sinking of RMS large, or anybody of thousands of comparable historical events. Yes, you’ll travel back in time however solely into a parallel universe. If you shoot yourself however it’s another you in another universe, no contradiction in terms arises. You travel back in time to own {shakespeare|Shakespeare|William Shakspere|Shakspere|William Shakspere|the bard|dramatist|playwright|poet} autograph your copy of “Hamlet” however in this parallel universe Shakespeare will currently write “Hamlet” supported your copy and no contradiction in terms results. However, the one purpose I realize attention-grabbing is that if you finish up within the future, or within the past, area unit you actually within the future or the past? No, the sole time you’ll exist in is that the gift, your right here and currently time. it’d be a special time from what you antecedently knew, however still where and whenever you exist, you merely exist within the currently.

# Is time travel possible? It might already be the case that point travel has been documented at the quantum level though that might be hospitable interpretation. Before i purchase to the specifics, I simply have to be compelled to entails that with reference to the laws, principles and relationships of physics, time is invariant. Operations in physics stay invariant in time whether or not time is moving as we tend to ordinarily understand it (past to future) or back to front (future to past). for instance, gravity would operate as per its traditional grab-ity self in an exceedingly world wherever time flowed backwards. there is many a operation one might film that once the film were run backwards, one would not be any the wiser. Tree branches processing within the wind involves mind, or the approaching along, collision, and rebounding or separation of 2 table game balls. Okay, having established that once it involves physics, physics does not care that direction time is flowing, there’ll be no violations in those laws, principles and relationships of physics future to past, we tend to currently come back to the delayed double slit experiment.

In the traditional double slit experiment, you have got AN electrode that fires one lepton particle at a time, such one lepton completes its journey before subsequent one is dismissed, at 2 side-by-side slits. If one or the opposite slit is open, the one-at-a-time electrons have the open slit to a detector screen behind the slits. The detector screen gets hit in nearly constant spot anytime once every and each lepton particle passes through the only open slit. that’s clear-cut. If each slits area unit open, the lepton shape-shifts into a wave (how i do not know), passes through each slits (as solely a wave can), morphs into a particle and hits the detector screen. The distinction is that once enough electrons are dismissed, and have passed or waved through the double slits, the hits on the detector screen don’t seem to be in exactly one or 2 spots however all-over-the-map, albeit all-over-the-map in an exceedingly classic wave interference pattern. Okay, that is the classic experiment.

Now we tend to do a variation on the theme, the delayed double slit experiment. Electrons area unit dismissed one-at-a-time, with each slits wide open. AN all-over-the-map classic wave interference pattern ought to seem on the traditional detector screen once enough electrons are dismissed. However, additionally to the traditional detection screen, there area unit 2 different detectors positioned behind the traditional detector screen that area unit every in an explicit line-of-sight with every of the 2 slits. The lepton is dismissed. It morphs into a wave and passes through each slits then morphs into a particle. however before the lepton, that has already capable each slits, will hit the detector screen, the detector screen is removed to reveal behind it the opposite 2 line-of-sight detectors. currently presumptively once the lepton has passed tho’ the double slits it’s insufficient too late to vary its mind concerning wherever it’s attending to hit. solely a little few ought to be detected by the 2 line-of-sight detectors aligned with the 2 slits. Alas, every and each lepton are detected by one or the opposite of the line-of-sight detectors. it’d seem that the lepton will amendment its mind once it’s already well-versed each slits and instead seem to own well-versed one or the opposite of the 2 slits. One interpretation is that the lepton, once having capable each slits, completed the gig was up, cosmopolitan back in time, retraced its path and capable one or the opposite slit.

As AN aside, the late Nobel Laureate Feynman noted that the double slit experiment visited the center of quantum unfamiliarity. I mention this as a result of it had been constant Feynman World Health Organization urged that a antielectron (an anti-electron) was simply a standard lepton that was going backwards in time.

# Is time travel possible? I actually have many different points to create concerning the idea of your time travel.

Firstly, there’s author Hawking’s plan of a Chronology Protection Conjecture that postulates that there’s some yet undiscovered law of physics that prevents time visit the past and so makes the cosmos a secure place for historians to strut their stuff.

Secondly, it’s been same that you just cannot travel farther back in time than the date it slow travel ‘device’ was made, be it a hollow or another gizmo. thus if some genius builds a time move ‘device’ in 2014, he isn’t going anyplace into the past. however in 2015 he will travel back to 2014 and in 2114 he might travel back to any time between 2114 and 2014. The analogy is that you just cannot travel through a tunnel before once that tunnel was designed. Thus, we do not see human time travelers as a result of no human time move ‘device’ has however been made. The flaw there’s that does not disallow ET from visiting World Health Organization might need made a time move ‘device’ many years agone. Recall those pestering UFOs tho’ they do not appear to cluster around important terrestrial historical events thus perhaps ET does not care concerning our history and area unit simply here on vacation from their future.

Thirdly, presumptively it slow move ‘device’ is mounted at some type of celestial coordinates. as a result of everything within the cosmos is in motion, after you reappear into that cosmos once beginning on a time move journey, whereas you’ll be at those self same mounted celestial coordinates the remainder of the cosmos would have stirred to differing celestial coordinates. So, if you begin enter London you will not find yourself in London on down, or up, the time move track. Finally, the idea of your, or the long run or of the past or your past is merely relative to what you decide on as some mounted purpose. If you choose your date of birth as that mounted purpose, then clearly you’re currently within the future relative to your date of birth. If you choose the idea of AN ever current currently, this, as a hard and fast purpose, you’re neither within the future or the past relative to the currently nor can you ever be. That after all does not imply you cannot recall your past, what existed before your currently (although the past normally is additional abstract) or set up for your future once your currently (although the long run normally is on the far side your control).

# Is time travel possible? there is yet one more kind of time travel, or a minimum of the illusion of your time travel, and that is via the cinema. Films and television shows involving time travel area unit several and infrequently legendary. however that is just about the medium I would like to explore here. One will program time travel into a model. you’ll have a computer game wherever the characters travel backwards (or forwards) in time, or have a software package program that loops around back to the start. currently the question is, may we tend to be characters or virtual beings in an exceedingly Simulated (Virtual Reality) Universe? If thus, the software package programs that run our virtual show may give time travel, or virtual time travel, however still time travel that might seem to America to be quite real. currently wherever will our sense of reminder very come back from?

# Is time travel possible? there’s one different kind of pseudo ‘time travel’ towards the long run which will be debunked. presumptively the sole means you’ll apprehend what the long run brings, while not advantage of any theoretical ‘device’ which will propel you there at a bigger rate of knots than at one second per second, is to remain alive. Once you kick-the-bucket that is it. Your second per second journey towards the long run is over. it is a pity that that superfluous stock you hold simply happens to sky-rocket to fantastic values at intervals per week of your ending, or even you’d love to understand if ET exists however the invention happens many days too late as way as you’re involved. after all some may claim AN lifespan can alter you to stay up up to now with future happenings from that heavenly vantage high within the sky, however except for that, there area unit those that claim to own junction rectifier past lives or existed in past incarnations. Thus, you’ll still continue your journey to find what the long run holds by passing on to a different body via being formed once more (and once more and again). there is one large downside but with ‘remembering’ alleged past lives. Your mother’s ovum cannot keep in mind your past lives. Your father’s sperm cannot have any recollection of your past lives. Therefore, the you that involves pass at conception cannot hold any memory of past lives. So, wherever did your memory of past lives come back from? may I recommend that it had been internally generated out of illusion, that maybe a belief that you just existed within the past can bring about to a belief that you just can exist once more within the future, and as a pseudo kind of lifespan and as a pseudo kind of ‘time travel’ that provides you comfort. Anyway, that idea could be a very way out methodologyology of ‘time travel’ however one which may be laid-off despite the numerous those that ostensibly believe that they so have ‘time travelled’ towards their endless future via this method.
