Funso ngati pali makina a nthawi, ndilo chidwi kwambiri. Yankho la funsoli makamaka limatanthawuza kuti "nthawi yamakina" ndi "alipo."
Ndipotu, kulipo, kulipo ndipo kudzakhalapo - ndikodi, chinthu chimodzimodzi, ngati makina a nthawi alipo. Ndipotu nthawi imakhala yosagwirizana. Maganizo amenewa alipo. Mwachitsanzo, Seth Lloyd adatha kukonza mpata wotsekedwa kotero kuti malo a photon mmenemo sanafalitsidwe osati mlengalenga, koma m'kupita kwanthawi. Ndipo izi zikutanthauza kuti, mwina, "makina a nthawi" alipo.
Kodi Einstein ananena chiyani?
Iye, monga mukudziwira, adapanga chiphunzitso chogwirizana . Malingana ndi chiphunzitso ichi, zikuwoneka kuti funso loti pali nthawi yosindikizira makina liyenera kuganizidwa pofuna kutsimikiza kuti kulipo kwake m'moyo weniweni, osati mu buku la Wells.
Ndipo Einstein ankaona nthawi osati chinthu china cholingalira, koma monga gawo lachinai la danga. Mwachidule, izi zikutanthauza kuti pali "liwiro la magawo anayi" la chinthucho, ndi chinthu chosasuntha (panthawi yopuma), ndilofanana ndi liwiro la kuwala. Koma ngati chinthucho chimasuntha, chiwerengero cha mawindo ake (atatu-dimensional ndi four-dimensional) akadali ofanana ndi liwiro la kuwala, zomwe zikutanthauza kuti mofulumira chinthucho chikusunthira mu danga, pang'onopang'ono imasunthira mu nthawi. Ndipo ngati maulendo atatuwa akuyandikira kuuluka kwa kuwala, ndiye kuti liwiro likuyandikira zero. Izi ndi zotsatira zotchuka za nthawi yowonjezereka, zomwe olemba zamabodza amapenda kuti azikamba. Momwemonso, akatswiri a zakuthambo omwe anabwerera kuchokera kuulendo sankagwira ntchito bwino: anzawo anali atamwalira kale . Kodi siyimakina nthawi?
"Mipando" ndi "wormholes"
Ndipo Einstein adapeza kuti nthawi imadalira mphamvu yokoka: pafupi ndi matupi akuluakulu amatha kuyenda pang'onopang'ono. Choncho, mwanjira inayake kusokoneza danga, monga momwe mphamvu yokoka imakhudzira, mukhoza kupanga "mabowo" kudzera mmenemo. Ndiye, muzochitika zina, kudzakhala kotheka kuswa ubale wa causal ndi kuchoka mu "burrow" musanapite kumeneko. Ndipo izi ndizovuta. Apa ndi Einstein yekha
Kuyesanso kwina kumvetsetsa ngati pali makina a nthawi, kumagwirizana ndi mabowo wakuda ndi nthano kapena zenizeni, sikunathenso kumveka bwino. Mulimonsemo, zimakhulupirira kuti zimphona, kufa, zimapanikizidwa. Koma vutoli silipita kulikonse, koma limasanduka kanthu kakang'ono, koma ndi misa yomweyo. Izi ndizokuti mphamvu ya chinthu choterocho ndi yaikulu kwambiri. Mwachiwonekere, kwinakwake pano ndipo ayenera kukhala malo olekerera, kutulutsa nthawi yowonongeka, koma izi sizingatheke. Ndizosatheka kugwiritsa ntchito "makina" otere: asanalowe chakuda chakuda, munthu amatha kusokonezeka motsogoleredwa ndi mvula yamakono.
