This May Change Your Mind About Going Back in Time

SHARE:

Adjust text size:


If a time machine was invented tomorrow, would you go through?
Enlarge picture
For us, wanting to go back in time is as natural as thinking and breathing. Around the world, countless people, myself included, believe that a simple trip to a certain point in our past would most likely change the course of our lives, maybe for the better, because I imagine no one would like to go back and make things worse. Some people even think about this day and night, while others dismiss the thought as impossible within a few minutes. But, then again, there are those who dedicated their life's work to finding a way of accomplishing this long-standing dream.
 

Over the years, numerous ideas of how to create the time machine have appeared, and they cover almost all possibilities, from generating wormholes between the folds of space to accelerating a cylinder at super-high speed. However, current technical limitations mean that these hypothetical constructions will not become a reality very soon, as most of them require materials that haven't yet been discovered. And these materials have to have properties that are not yet fully understood, but merely deduced through painstaking calculation.
 

But the real question that arises, if we imagine that we could go back in time, is “would we really want to do it?” Understandably, the desire to change things for the better in your life is to be praised, but who is to say that a potential time traveler won't try to change things that happened in other people's past, say an ex-boyfriend or girlfriend, or another friend that went through a tragic event? Regardless if, morally speaking, the change is for the better or for the worse, what gives a certain individual the right to make changes to everyone's future?


I have on numerous occasions thought of going back in time and stopping Hitler, Lenin and Stalin from ever taking power in Germany, and Russia, respectively. But such an action, which would seem minor in, say, 1920, when no one knew Hitler, would have massive repercussions on our current time line, wouldn't it? I mean, no more second world war, no more Korea and Vietnam conflicts, no more Cold War. And that would be just great, when looking at things simply.
 

Less victims of the war would mean less tragedy in the world, less destroyed families, less drama and so on. But then again, there are the inventions that were created on account of these wars, without which the world wouldn't look like it does today. For one, we wouldn't have jet liners and jumbo jets to carry us around the globe in a single day. We wouldn't even have rockets, boosters and space shuttles for that matter. No rovers on Mars, no Moon landing, no space probes throughout the solar system.
 

All these machines are based on German-produced rockets, which were created because Hitler wanted a way to reach England without actually invading it. After the war, the Americans were first to most launching facilities, and learned all the secrets that the Nazis had. On the other hand, the Russians reached the rifle, machine gun and ammunition factories and thus the AK-47 Kalashnikov appeared.
 

The Clock of the Long Now is designed to keep time for 10,000 years

These are only few of the implications of a possible trip back in time. But imagine that you go back to save a relative from an accident. The “ripples” of your decision will be amplified by each passing second. In other words, if you go back 1 hour, the implications are not that large. But if you go back 50 years, then the consequences would be massive.
 

The real issue here is “are we ready, as a society, to live with such responsibilities on our shoulders?” And can we afford to say “yes” given the fact that we don't even know how the space-time continuum would react to a change. It could be that some physicists are right, in that, when we go back in time, change something, and then come back, then our reality could simply revert to its original state, as the ripples I was talking about earlier start pounding our “artificially-created” reality.
 

One thing's for sure – those who believe in a higher power, be it God, Allah, or Buddha, will strongly oppose any attempt of going back. If an announcement was made tomorrow, that NASA or ESA created a time machine, undoubtedly the first reaction that people would have would be fear, followed promptly by anger, and then fear again.
 

I don't want to incite panic in any way, but they would be right. And I say this because, if someone does go back, then he or she could inadvertently trigger a chain of events that could lead to someone's grandfather not being born. This would mean that a human being would simply disappear from the face of the Earth, without anyone ever remembering he or she ever existed.
 

This of course holds true only if theoreticians are right, and the past and future are connected to each other with a time line. Otherwise, a volunteer entering a time machine would remain stuck in the past, without any way of going back, and without influencing anything in the present.
 

You could ask yourselves if you would do this. If you would take it upon yourselves to go into the unknown and take action that could potentially shape the development of the entire human race. If you would like to have the fate of the world literally on your shoulders. Don't get me wrong, I'm all for exploring our limits and achieving the maximum that we can, but I also believe that we have to do this responsibly, in that we shouldn't hurry to make the first time travel just for the sake of it.
 

Some may argue that no major breakthrough was made without taking risks, and that's entirely true. I mean, almost. The risks in all other areas of science are containable. That is to say, if you take a chance to defuse a bomb and it doesn't work, a building or area gets destroyed. But if you change something in the past, then there is no cleaning up afterwards. Those things simply wouldn't have happened.


Indeed, if tomorrow we create the machine, and the science behind it is discovered 100 years from now, then the trip back in time should take place 100 years from now and not tomorrow, because the possible implications are extremely devious, simply because no one, by some theories, would know that something went wrong. Only an outside observer, stationed, say, on the Moon, would get up on its 5 feet and say “ooops, what happened?”

I completely agree with this article. Going back in time will definately do more harm than good - IF IT IS POSSIBLE!

Comment #1.1 by: jessica on 23 May 2012, 01:10 GMT

not in my book it wouldnt because ,i would just wanna go back to see where i already been or what i miseed before i was born , i would try not to interact with anyone or prevent things from happening , i dont know if i would be able to do that anyway , it might be out of my control , what originally happened might just have again , history may just repeat itself all over again , , that's what i think so i dont know what makes people think they could change history , , they cant , history will just repeat itself, no one can stop what's meant to be, that's what i believe.

"less families" ... "less victims"...? How about fewer families and fewer victims. Note the difference.

In my opinion if anything any one will ever do by going back in time, would change the timeline.... it already has. I.E. If we ever do travel back in time then it has already been taken into account by our present time. If the other case were true then it would probably lead to a timeline where time travel wasnt created at the exact same time and thus the person traveling back either would not be the same person or would not be traveling to the same date/time. It is an impossiblity, and while the other may be true and each choice creates a different timeline, then whatever choice someone makes going back obviously wasnt made on my timeline and thus I will be unaffected.

If one were to travel back in time and change anything that were to affect them they would already be feeling the repercussions of what they did, as would anyone else affected. Traveling back in time would be cool and is doubtfully dangerous. And as for the going back in time and stepping on a mosquito that lead to the creation of humans, nothing would happen. The mosquito would die and you would cease to exist as would all others, but since you don't exist you would never have stepped on the mosquito therefore you are back where you started, having done no harm. Fun.


Comment #5 by: Kyle on 17 Jun 2009, 12:28 UTC reply to this comment

It is as simple as this, we will never travel back in time because if we ever do, we would know. If we ever traveled in time somebody would have already arrived in the present time. Think about it hard, if nobody has been here already, they never will.


Comment #6 by: Day on 18 Aug 2009, 22:23 UTC reply to this comment

i think time travel would be fun, highly unlikely but fun nontheless, im sure that if time travel was possible laws and restrictions would be applied so catastrophes could be prevented.


Comment #7 by: cyp on 05 Oct 2009, 10:05 UTC reply to this comment

probably traveling in time is possible (for some time periods at least) and if you really want to change something in the past , to change your life to the better... well those repercusions do not matter to you... and yeah, you are a selfish person... so what? most people are selfish... the problem is that they do not like to admit it...


Comment #8 by: Robby Keller on 31 Oct 2009, 21:17 UTC reply to this comment

Time travel could be possible. But maybe not in the way everyone thinks. Travel back in time might take you back to were you were at a certain time. But wouldnt your mind be back at that state. Going back you wouldnt be aware of the future or even aware you time traveled in the first place. Hope its understandable. But what if time travel can only be experience in a ghost like state. For instance you could go back and see events but at the events. Time travel suppose to be faster than the speed of light and body would tear going that fast. But travel in another state maybe concsiences or ghostly state. Could explain people experiencing seeing ghosts. May sound just as crazy as any other theory but its the only feasible thing I could think of.


Comment #9 by: victoria H on 04 Jun 2010, 02:30 UTC reply to this comment

Interesting views...but never the less improvable. the theory of time travel is just that! one silly theory . time is relative to views and just an illusion at best! while i admit that under some circumstances it is possible to peer back into time ( outer space objects ) physically going back in time just cant be done because there is nothing to go back to! space is not curved but in fact runs constant, almost like a straight line and as you all know a straight line does not fall back into it self. Also even if it were possible to go back would you really trust a race of people who cant even control their space in time? The people of this planet just did not do a good job!And now you want to go back and try it again? What a mess that can be! Better for all concerned that you cant! Say , how about trying to improve your own lot in time and space?


Comment #10 by: emily on 22 Jun 2010, 14:29 UTC reply to this comment

from kyle "If we ever traveled in time somebody would have already arrived in the present time" but what if they studied that eras time frame?? therefore they would wear what we wear and they could pretend to be a tourist that might explain tourists in areas where everyone of that area knows a tourist wouldn't travel to see or backpack because there isn't anywhere they could camp nor is there any hotels or motels :)... but i like the ghost theory. and if we could go back in time i think we would have much more technological advances then what we have now?


Comment #11 by: shuballs on 14 Aug 2010, 09:11 UTC reply to this comment

I would expect if you went back in time, in reality you would not exsist you may see events and people, but they can not see you, there fore you may not be able to change any thing, (just a lay mans thoughts


Comment #12 by: Michael G on 18 Sep 2010, 16:56 UTC reply to this comment

I want to go back in time to stop my self from a certain incident that lead to my divorce and the consequent death of my children my wife falling out of love with me and l;eaving me for someone else and the lose of my family fortune of over £6million and childrens future how can I do this ?


Comment #13 by: Mr.deed on 20 Oct 2010, 00:20 UTC reply to this comment

time travel is possible!!!! but not with the body....only with the mind ..and yes we create a new time line ...our time line ....sry for my bad english ...i will publish my article .... regards mr.deed


Comment #14 by: EB on 27 Oct 2010, 18:53 UTC reply to this comment

Consider another possiblity. Instead of traveling back to a point in time as we are now, that is the current age and physical stature that one has when they enter said machine and travel, we are able to travel on a linear point backwards within the perameters of our own lives. In other words, imagine the ability to travel back to a specific point in your own life and relive that period in time again. Go back to fix something or just relive it. The implications would be far less reaching for humanity itself. But you could impact your own life in ways unimaginable.

Perfect...how do I accomplish this ? Really, I am not kidding. Thanks

This is quite interesting. i would like to back in time myself.

I'd love to go back in time. I don't really care about my past but to go back and meet, for example, George Washington would be so wonderful. To tell you the truth, I hope it will be possible.

Comment #16.1 by: hola on 03 Dec 2010, 09:43 GMT

well don't you think George Washington would had want to do the same, to go back in time?

an ideal can be mathematicaly logicaly viable but physicaly troublesome, consider solving the kinetic equation s=Ut 1/2at^2, for some parameters a negative vlue of t could also be a solution, but what is that physicaly?

Buddy, slowdown before you hurt your-self.


Comment #19 by: Robert on 16 Nov 2010, 02:19 UTC reply to this comment

If you had one night that you truelly messed up and had one chance to fix it would you or let it slip? My name is Robert im 15 and me and my ex-girlfriend Ashley started talking about if we could go back to the night that i messed up would i fix it or let it slip? idc who reads this but i truelly love her and she truelly loves or loved me and i messed up and now her parents all her friends and her family hate me and will never forgive me so now you tell me would you want to have one night one moment and fix it or let it slip i may be only 15 but i know for sure she is the thing that makes my world go round and im not gonna give up on that im going to fix it and go back and fix it all just one moment could stop the world or have someone die or disappear or be born so the real question in this is would you want to have one moment to fix in your life or just go on living without knowing at all if it would be different????

Comment #19.1 by: Terry on 27 Apr 2011, 02:20 GMT

i really want to go back in time to my graduation....day....to take a letter with me...then maybe i wouldnt have to come back here...the next day just wait for my man to come get me...i messed up a lot of times and that time was my biggest mistakes sigh me and my man are going to break up after this summer probly i really want to be with him i dont know what to do except cry any suggestions?...


Comment #20 by: MR_MIK on 20 Mar 2011, 09:10 UTC reply to this comment

my wish is to go back in time ;)...


Comment #21 by: Tristan on 28 Mar 2011, 23:42 UTC reply to this comment

i dont think you would be able to change anything, Imagine... you go back to change a disaster such as a earthquake that killed alot of people, But once you have gone back and warned people, in the future it would have never happened so you would not have changed it. so it would happen all over again. Right? its hard to explain


Comment #22 by: Sippy.cup on 08 Jul 2011, 01:38 UTC reply to this comment

But what if those v-rockets, jetliners, inventions etc. of said time period which you'd go back to, were to happen regardless. Therefore all that was bound to happen in the first place.


Comment #23 by: theluckyman on 09 Jul 2011, 09:39 UTC reply to this comment

Would it be wrong to suggest even in science fiction,that one person could in there wildest dreams be able to talk to themself-whilst sat in a chair,facing themself.That is something I would want,to sit with with me and ask me how I was getting on with myself.


Comment #24 by: theluckyman on 09 Jul 2011, 09:45 UTC reply to this comment

In the film back to the future,they talk about thespace time continuem.In the film de ja vue ,they try to fold time back on itself-and send a man back to save a life -but another dies because of it.That I feel is the only danger of messing around with time.But how can we ever know what lies beyond our own planet-as no body has gone to theedge of the universe ,as we know it to see what happens.


Comment #25 by: Christina on 06 Nov 2011, 20:22 UTC reply to this comment

I am certain God will not permit backward time travel. As outlined here, it is fraught with hazards and impossibilities. We have to go forward, to the goal of eternity. I personally would love to go back to savour just one day with people I loved and whose deaths have caused unending sadness for me.. not to be!

Comment #25.1 by: TIME M CREATER on 08 Nov 2011, 10:46 GMT

have u ever seen god???????i dont think he dos exist cause d pain i got in my life isnt just let me go!!!!!!& if god cant fix it up den i will have to do it by myself ,dats d reseon i want to create a time machine ,not to do somethin difrent or change somthin but to know wats gonna happn next and be prepaired for it ,im just 12 ,but i got a feelin dat i can do it & dis is a feelin dat i never got in my life ,& from doin dis no 1 can stop me!!!NOT EVEN GOD!!!!

Comment #25.2 by: george on 04 Dec 2011, 02:45 GMT

Well in the bible it said that God let someone time travel i'm not sure if it was backwards or forwards but either way if he let someone do that why wouldn't he let all of us time travel?


Comment #26 by: TIME M CREATER on 08 Nov 2011, 10:33 UTC reply to this comment

whoose changin any 1 's life ,its just for ones desire and lifechanger and u think time machine gonna take a lonG time to become reality ,den ur rong cause iam gonna make it and THATS MY PROMISE TO ALL!!

I would go back to the 70s and stop my mom from smoking so she wouldn't die of lung failure on my 16th birthday I don't really think that would effec anything but my happiness.


Comment #28 by: sqoti on 11 Nov 2011, 18:46 UTC reply to this comment

You ever thought that maybe you are the present and everybody else in your life came from the future. They traveled back before you were born and this is now your reality.

i always wanted 2 go back in time. thx for ruining my dreams

Comment #29.1 by: Brittany on 17 Mar 2012, 05:29 GMT

Ugh, I so feel you.


Comment #30 by: SASS on 03 Dec 2011, 01:26 UTC reply to this comment

Sign me up....I would try in a heartbeat. Just a couple of months back...and I would relive it - I wouldn't have to come back. It would be worth and possible risk.....


Comment #31 by: Tessa on 07 Dec 2011, 20:15 UTC reply to this comment

Very interesting thought. Do you think that no matter what, things would have come to be invented, anyway? What if one wanted to just go back and become a mere observer, which would equal less consequence? I do concur, that it would pose to an individual wanting to try to "go back", a certain responsibility based on only the knowledge we have deduced from our studies of spacetime; however, what if those studies are, indeed, incorrect, and the only way to find out is to actually go back and find out? As one of the rules of our Universe states, positives come from negatives; therefore, anything that happens will just work out somehow. It is only fear that would stop us from wanting to go back. What do you think? Would you do it? I think I would anyway... I think...


Comment #32 by: Brittany on 17 Mar 2012, 05:27 UTC reply to this comment

I agree with the article. I've always wanted to go back in time, but also considered and was aware of every consequence the article stated. But seriously, I would love to go back in time, so badly at times, even with saying "no" at times.


Comment #33 by: Ben on 19 Mar 2012, 01:23 UTC reply to this comment

I would love to go back a few days, be it 2 or 3, so that I could tell myself to begin on my exam assignment early instead of having to sit up all night writing this stupid paper.


Comment #34 by: G_Mack on 19 Mar 2012, 09:01 UTC reply to this comment

Well the concept is interesting I see two possiblities: one is the theory of alternate realities which explains why it time travel is possible how come no one has ever encountered a single person from the future to date i believe that is a good basis to believe that our current reality is the unaltered reality and going back in time cannot affect our timeline and you are really shifting into a new, alternate, reality by going back in time a reality that follows the line of you, or someone changing what you change and you cannot return to the present you came from. Of course the second concept is that backwards time travel is impossible thus nobody from the future has tried it. There is a final darker theory that we as humans do not exist long enough to discover a possible form of backwards time travel.


Comment #35 by: busterfelix on 22 Mar 2012, 03:21 UTC reply to this comment

David Deustch has pioneered and refined our notions about time travel. To put it simply, in multiverse theory, if one were to go back in time you would end up in an alternate universe exactly the same as the one from your own with only one difference; a time traveller has arrived in this one (you). Any changes you make will change that universe but not yourself or the universe you originated from. So since there are an infinite number of parallel universes since the beginning of time until the end of it, you could change all you like without having to worry about it changing you or the universe from which you originated. As long as you have the best intentions (and the means) of changing small events in the not so distant past you should be able to enjoy the fruits of your labor without any bad feelings about changing history. Because in that (the changed one) universe, you were always there to change it (as a time traveller) and in the "original" you will have simply vanished from your present never to be seen again. Read the Fabric of Reality and you will see what I mean.


Comment #36 by: scottyg on 11 May 2012, 04:57 UTC reply to this comment

it is possible --it has already happened---it will occur on multiple occassions again and again---even half of the people reading this article already know it has happened!!! deja vu ring a bell??? been there,seen that and feel you have done that??? well you have!!! it is proof that someone has accomplished the impossible!!! the earth is spinning at 2400 miles per hour and you don't even realize it--because your totally unaware it's happening doesn't mean it's not happening!!! the only people totally aware of the changes are the one's who have gone back in time...those people are aware of the changes they could make so they try their best not to make significant changes...but occasionally the small personal changes that are accidentally made are minor instances that affect some of us in way's that we don't even realize and barely notice-ie: deja vu


Comment #37 by: jessica on 23 May 2012, 01:24 UTC reply to this comment

if i were to go back in time ,i would only wanna go back to see where i've been and what i missed before i was born , i dont think it would be possible to change anything , i think history would just repeat itself all over again , you cant change what's meant to be.


Comment #38 by: ladybugg on 28 May 2012, 04:24 UTC reply to this comment

In a religion standpoint if being able to change the past wouldn't it be meant to happen?
