TIME TRAVEL: Fact of Fiction

[donlucchese]

Salaam wakuu,
Nakumbuka wakati nipo mdogo kuna muvi baba aliinunua inaitwa Back To The Future iliyoactiwa na Mathew J FOx. Muvi hii ilikua inaonesha jinsi mtu anavoweza kusafiri katika muda (time travel) kurudi kipindi cha nyuma.

I was fascinated by this technology nikadhani ni kweli inawezekana at that time. Sasa nimekuja kusoma baadhi ya articles ambazo zinaelezea swala hili, kuna jamaa akaniambiwa according to Newton's theory of relativity, ukiweza kutravel kwa speed kubwa ukauzidi mwanga, then unawea kusafiri katika muda. Juzi juzi kuna documentary ya jamaa mmoja nimesahau jina lake ila inaitwa Conspiracy theories, kuna jamaa mmarekani alikiri kwamba teknolojia hii ipo naimekua ikitumiwa na US DOD kwa miaka kadhaa na akatoa ushahidi wa picha jinsi alivyotravel in time wakat yupo mdogo nakutokea katkat ya uwanja karibu na sehem raisi Kenedy (kama sijkosea) alikua anasalimiana na watu.

Naomba kwa wataalamu wakuu wa mambo ya kisayansi waweze kunijuza mimi pia na wengine wasiofahamu, kama hii teknolojia scientifically imeshawezekana na mechanism yake.

NB; kama inawezekana aisee nitaomba nirudi Year 1905 wakat wa mwanzo wa vita vya maji maji nimuone kinjekitile anavyowazuga raia na dawa yake feki ya maji.

Mdau hii ni Science fiction ipo, ki Movie zaidi hebu tafuta Movie ya Will Smith MIB 3 ina hiyo kitu.

Cheki hii nukuuu

Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space.
Time travel could hypothetically involve moving backward in time to a moment earlier than the starting point, or forward to the future of that point without the need for the traveler to experience the intervening period (at least not at the normal rate). Any technological device – whether fictional, hypothetical or actual – that would be used to achieve time travel is commonly known as a time machine.Source

We all travel in time, into the future, one second per second.

Time travel into the past, for any material object, so far, per Einstein's relativity (not Newton's as mzeewaloliondo posited) and the Standard Model of Particle Physics, is impossible.

I wrote this on my Geocities website in 1999 (middle finger to Yahoo! for taking Geocities down).It remains so.

The reason being, to travel back in time, essentially, is to travel faster than the speed of light. Time is just the fourth dimension of the space-time continuum.

The speed of light is the known speed barrier for material object in the universe.

By Einstein's Relativity, the reigning theory on the subject, for any material object, however small, the more you approach the speed of light, the more two things happen.

Time is dilated, space is distorted. The object becomes bigger and bigger, and heavier and heavier. Time, from the perspective of the object, starts to move slower and slower.

In essence, if a material object were to reach the speed of light, it would turn into a singularity, with infinite mass.

How are you going to move an infinite mass even at the slowest speed, let alone at the speed of light?

Therefore, by our currently known technology, time travel by a material object into the past is not possible.

Of course you have science fiction authors anticipating the tachyon, which could only move at a speed greater than that of light, essentially isolated in another universe.

Or the occasional Einstein-busters, like the Italian experiment that prematurely reported a faster than light particle velocity, which was later debunked. But that's all, science fiction and premature ejaculations.

Luckily we have our minds to reminisce, and can travel into the future one second per second from the observers perspective.

What kind of question is this??
You think thats possible?? I mean for real! ?!
Come on now! ! Its just a movie!!

If thats possible! Why we don't see Arnold schwaznegar or Rambo in iraq and Afghanistan! ??

It is a legitimate question. Even if time travel is impossible, it is important to explore why is it impossible as I have pointed out above.

There is no stupid question, as long as it is genuine. Since all genuine questions are rooted in the desire to alleviate stupidity. And that, in it's totality cannot be stupid.

Kuna mtu aliuliza kwa nini rangi ya bluu inaonekana ya bluu na nyekundu inaonekana nyekundu, na utajuaje kwamba unayoona bluu wewe si nyekundu kwa mwenzako na mwenzako anayoona bluu si nyekundu kwako? It turns out the root of the issue, at least for the first question, lies in quantum physics.

Maswali mengine yanayoonekana rahisi ama ya ajabu yanaibua majibu yenye insight tofauti.

Kama vile Newton supposedly alivyojiuliza kwa nini vitu vinaanguka chini na sio juu, which lead to the discovery of gravity.

Au Einstein alivyojiuliza itakuwaje kama mtu atapanda kwenye muonzi wa mwanga na kusafiri nao, which led to the discovery of relativity.

Thanx chief, very well explained.

 

[Gurta]

Thanks Kiranga for appearing at last and for the well put argument there.

Now, where do these contentions (whether founded or unfounded) "people say" or rather "US DoD or CIA" has the technology come from? Shouldn't it be that, that which is thought to be, is, in the actual sense?

 

[itara]

Kwa fikra zangu za kifalsa na usomi wa matini mbali mbali...time travel inaezekana na ni real ila itz is not emperical...nikimaanisha kuwa haielezeki ki fizikia...according to the concept of phyisics

sasa hii mifano yako ndio inayosababisha mparaganyiko wa fikra!! huwezi kujiuliza kitu ambacho logic haikubaliani nacho eti huenda ukagundua kitu usichokijua!!

anaeuliza kwa nini rangi ya blue ni blue!! yeye lengo lake ni kujua sababu? au ana jambo lingine anatafuta??

unapoanza kujiuliza kitu unatakiwa uwe na lengo !!

Mfano mwingine wa fikra au elimu isio na manufaa ni kama ule wa kwenda kuangalia kama kuna uwezekano wa kuwa na maisha ktk MARS!!
Wakati hii dunia tunayoishi, binaadamu ame occupied only 10% ya dunia! na 90% iko tupu!!

NA wakati huo huo USA wanatumia billions of dollars kwenda kwenye misheni zisizo na faida WAKATI NYUMBA KWAO KUNA ALMOST 3 MILLION PEOPLES HOMELESS!! WAKATI WA WINTER WATU WANAKUFA NA BARIDI KWA KULALA MITAANI!!

sasa hii time travel ina lengo lipi?? hebu nisaidie hapo!! manake ukiishughulisha sana akili kwenye mambo yasio na maana! jamii inaweza athirika na wewe huna hata habari!! KAMA HAO WAZUNGU WANAOJIFANYA KUWAV NA AKILI NYINGI!!

Hebu tuumize vichwa kujaribu kutatua matatizo tulionayo kwanza!! tena yako mengi mno!! Hii time travel tuiache kwenye MOVIES KWANZA!!

 

[Kiranga]

sasa hii mifano yako ndio inayosababisha mparaganyiko wa fikra!! huwezi kujiuliza kitu ambacho logic haikubaliani nacho eti huenda ukagundua kitu usichokijua!!

Logic gani? Unachosema wewe ukikichambua sana utakataza maswali kabisa.

Kitu gani ambacho logic haikubaliani nacho hapo? Uwezekano wa kurudi nyuma kwenye muda? Logic gani hiyo?

Kama Einstein kashatuonesha kwamba time is a dimension of the space-time continuum, what is so illogical about asking if it is possible to move back in time?

Katika physics hakuna kitu chochote strange kwa vitu kurudi nyuma in time, it is just a perfect symmetry of moving forward in time.

Kama unaweza kwenda mbele na nyuma in space, and time is just another dimension of the same space-time continuum, what is so strange about asking about going back in time?

Je mtu akikwambia katika multiverse huko kuna universes zilizo na three dimensions of time and one dimension of space, ambako katika time unaweza ku move dimensions tatu, sio mbele na nyuma tu, bali hata kulia na kushoto na juu na chini, lakini katika space una move mbele tu, utasemaje?

anaeuliza kwa nini rangi ya blue ni blue!! yeye lengo lake ni kujua sababu? au ana jambo lingine anatafuta??

Anataka kujua kwa nini rangi ya blue ni ya blue.

unapoanza kujiuliza kitu unatakiwa uwe na lengo !!

Lengo ndilo hilo, kujua kwa nini rangi ya blue ni ya blue. Hilo si lengo?

Mfano mwingine wa fikra au elimu isio na manufaa ni kama ule wa kwenda kuangalia kama kuna uwezekano wa kuwa na maisha ktk MARS!!

Manufaa kwa nani? Kwa mtu ambaye nia yake ni kujua jibu la swali, kupata jibu na kukidhi kiu ya kujua tu ni manufaa.

Isitoshe, vitu vingine huwezi kujua manufaa yake mpaka uvigundue na kuvichunguza kwanza.

Maxwel alicheza sana na equations kabla watu hawajaweza kugundua kwamba equations zake zinahusika katika kuonesha uhusiano wa magnetism, electricity and the speed of light. Watu wakazifanyia kazi mpaka wakagundua umeme, leo umekaa kwenye computer na mimi nimekaa kwenye computer tunawasiliana.

Ungekataza utashi wa Maxwell tungeweza kupata umeme kirahisi hivi?

Wakati hii dunia tunayoishi, binaadamu ame occupied only 10% ya dunia! na 90% iko tupu!!

Ame occupy only 10% kwa kigezo gani?

Ushawahi kusikia kitu kinaitwa "Extinction Level Event" wewe? Dunia ikipigwa kimondo kufikia "Extinction Level Event" bila ku explore sehemu nyingine watu watafanyaje?

Unafikiri kila mtu anafikiria kula ugali na kulala?

NA wakati huo huo USA wanatumia billions of dollars kwenda kwenye misheni zisizo na faida WAKATI NYUMBA KWAO KUNA ALMOST 3 MILLION PEOPLES HOMELESS!! WAKATI WA WINTER WATU WANAKUFA NA BARIDI KWA KULALA MITAANI!!

Wewe yanakuhusu nini? Waache watu wao waseme.

sasa hii time travel ina lengo lipi??

Unaifahamu GPS ile? Basi ile GPS system ile, inayosaidia watu kufahamu ramani kwa kutumia satellite, imeanzia kwenye hesabu na physics huko, kwenye Relativity ya Einstein hii hii tunayoiongelea inayohusika katika Time Travel. Kwa hiyo kama mtu asingejiuliza swali kuhusu habari za time travel, leo kusingekuwa na GPS. Hii ni application moja tu kati ya nyingi sana zinazoweza kutokana na research hizi.

Hayo ma weather satellite yote yanayowapa watu utabiri wa hali ya hewa na kutabiri vimbunga na mvua yanaweza kufanya hivyo kwa kutumia principles za relativity.

Kwa hiyo fikiri kama haya mambo ma GPS, ma satellite systems yanayotabiri hali ya hewa na kuongoza ndege, yanayotupa notice kwenye vimbunga yasingekuwepo kwa sababu hakuna watu waliouliza maswali ya time travel, leo tungekuwa wapi.

Everytime a plane lands safely, the GPS system used, the weather prediction system used, the tower control system used, all are using relativity and principles of time travel that you so readily dismiss without understanding.

hebu nisaidie hapo!! manake ukiishughulisha sana akili kwenye mambo yasio na maana! jamii inaweza athirika na wewe huna hata habari!! KAMA HAO WAZUNGU WANAOJIFANYA KUWAV NA AKILI NYINGI!!

Basically kila kitu kinachohitaji high precision in time kinahitaji Special Relativity na mambo ya time travel yanaingia hapo. Kuna processor za research computers zinatumia kanuni za relativity kupata accuracy in performance. Zinatumia relativity katika kuhakikisha magnetic field ya storage media ina store data accurately.

Hebu tuumize vichwa kujaribu kutatua matatizo tulionayo kwanza!! tena yako mengi mno!! Hii time travel tuiache kwenye MOVIES KWANZA!!

Kama hujaelewa the principles behind the concept, and the relevant questions, how could you dismiss that which you do not understand?

Historia ya sayansi na ugunduzi imejaa mifano ya vitu ambavyo viligunduliwa kabla ya kujulikana kwa matumizi yake.

Ukitaka watu wahangaikie ugunduzi wa vitu ambavyo wanavielewa matumizi yake tu unajionesha jinsi ulivyokosa kuelewa historia ya uvumbuzi.

 

[Kiranga]

Kwa fikra zangu za kifalsa na usomi wa matini mbali mbali...time travel inaezekana na ni real ila itz is not emperical...nikimaanisha kuwa haielezeki ki fizikia...according to the concept of phyisics

Kwa mpango huu kila kitu kinawezekana.

Hata kisichowezekana kinawezekana katika ulimwengu ambao kisichowezekana ndo kinawezekana na kinachowezekana ndo kisichowezekana.

Actually this is not such a strange thought.

There is a mathematical model for a universe that particles can move only faster than the speed of light, entropy could only decrease, and people are born on their graves and move backwards in time until they die in their mothers wombs.

The hypothetical particle that moves backwards in time is called a tachyon.

[kidole007]

kingereza kigumu but hyo ni ficction tu
naona majority ya wachangiaji wamezungumia moving with speed of light o somthing but mnakumbuka E=mc2
kwamba kitu chochote chenye mass kikweza ku attain speep ya mwanga doubles kinageuka kuwa enengy
sasa tupeni mechanism jinsi ya kufika 1990 hakuna?

Before we understand time travel, we should understand the fundamentals of time

Does time flow?

Does time have a direction?

kahtaan;
Hapo kwenye bold mbili nikuulize maswali:
1. Una uhakika gani kuwa kile unachokiona kwenye macho yako kama kilivyo, ndivyo ninavyokiona hata mimi? Kwa mfano, kile ninachosema mimi ni chekundu, na wewe unasema chekundu, unajuaje kuwa uwekundu ninaouna mimi ni sawa na uwekundu unaouona wewe? Kwa sababu inawezekana kabisa kuwa kilicho cheupe kwako ndiyo chekundu kwangu lakini wote tukiulizwa mimi na wewe wote tunasema ni chekundu, huo ndio ufafanuzi alioutoa Kiranga.

2. Swala la NASA kwenda kwenye sayari zingine wakitafuta kama kuna uwezekano wa kuishi kule, motivation kubwa nadhani si kuhamia huko, japo inaweza kuwa mojawapo. Ulishawahi kujiuliza swali kwamba je, tuko peke yetu kwenye universe hii? Je UFO's wapo kweli au hawapo? Na kama hatuko peke yetu, kwa nini tusiwatafute wenzetu waliko ili tuweze kufanya mawasiliano? Sema tu mimi ninachoweza kukuhakikishia kwa kutumia imani (siyo sayansi), the bigger chances ni kwamba we are not alone in the universe, na hiyo ndiyo nadhani ni motive kubwa ya projects za hawa watu wa NASA. Probably hata wao walishajua, ama kuhakikisha hilo ila hawawezi kuliweka katika publicity kwa sababu inabidi mpaka wawe na uthibitisho ambao ni emperical.

Time is actualy a pure scalar quantity with neither magnitude nor direction. So, what else?
