Musoro: Pfungwa Dzekutanga dzeDzidziso yeString
Dzidziso yetambo, imwe yenyanzvi huru mukutsvaga kugadzira dzidziso yakabatana yezvinhu zvese, inomiririra imwe yemabasa esainzi ane chinangwa chikuru munguva yedu. Inotsvaga kuyananisa quantum mechanics uye general relativity nekuratidza kuti zvinhu zvakakosha zvemuchadenga hazvisi zvinhu zvakaita semapoinzi, asi "tambo" dzine divi rimwe chete. Chinyorwa chino chinotarisa pfungwa huru dzedzidziso yetambo, chichipa maonero akareruka anobatsira kunzwisisa ndima iyi yakaoma uye inonakidza.
Nheyo: Tambo Nekudedera Kwadzo
Pakati pedzidziso yetambo pane chiono chinoshandura: pfungwa yekuti zvidimbu zvese zviratidzo zvekudedera kwetambo dzine divi rimwe chete. Idzi tambo, dzinogona kuvhurika (dziine magumo maviri akasiyana) kana kuvharwa (dzichigadzira zvishwe), dzinotenderera pama frequency akasiyana, ne pateni yega yega yekudedera inoenderana nechidimbu chakasiyana. Saka, erekitironi yakasiyana ne photon kwete nekuti zvinhu zvakasiyana zvachose, asi nekuti tambo dzinodedera nenzira dzakasiyana.
Pfungwa iyi inosvika pachiyero chehukuru. Matambo anofungidzirwa kuti madiki zvikuru, zvichienderana nehurefu hwePlanck (anenge \(10^{-35}\) mamita), chiyero icho fizikisi yetsika inobatanidzwa muzvinhu zvekufungidzira. Nekuti kutenderera uku kunoitika pachiyero chidiki kudaro, kuona kana kudzidza zvakananga netekinoroji iripo kuchiri kupfuura kugona kwedu.
Supersymmetry: Kubatanidza Mabhoni neFermions
Chimwe chezvinhu zvinonyanya kufadza zvedzidziso yetambo ndechekubatanidzwa kwayo kwechisikigo kwesupersymmetry, iyo dzidziso yekuenzanisa inoratidza hukama huripo pakati pemapoka maviri ekutanga ezvikamu: mabosons (vatakuri vesimba, senge maphoton nemagluons) uye mafermion (zvinhu zvine chekuita nazvo, senge maerekitironi nequarks). Supersymmetry inoratidza kuti chikamu chimwe nechimwe chine "superpartner" ine hunhu hwakasiyana hwekutenderera.
Kuisa supersymmetry mu string theory kune zvakanakira zvakawanda zvedzidziso. Zvinobatsira kugadzirisa kusawirirana kweStandard Model ye particle physics, senge dambudziko rehierarchy, iro rinosanganisira kutsanangura kuti nei gravity isina simba zvakanyanya kupfuura mamwe masimba makuru. Uyezve, supersymmetry inofanotaura zvidimbu zvitsva zvakaita se neutralinos, izvo zvinogona kusarudzwa kune dark matter - chinhu chisinganzwisisike chinoita chikamu chikuru chesimba guru remuchadenga.
Zvimwe Zviyero: Kupfuura Nguva Yenzvimbo Yemadimensional Mana
Dzidziso yetambo inoshanda mukati mehurongwa hunopfuura mativi mana anozivikanwa (mativi matatu enzvimbo pamwe nechiyero chimwe chete chenguva). Kuti masvomhu edzidziso yetambo arambe akafanana, mamwe mativi enzvimbo anofanira kunge aripo, zvichigona kuita kuti huwandu hwese husvike pagumi kana gumi nerimwe zvichienderana nerudzi rwedzidziso yacho.
Zviyero izvi zvekuwedzera zvinoumbwa zvidiki, zvinowanzoonekwa kuburikidza nemaumbirwo akaomarara ejometri anozivikanwa seCalabi-Yau manifolds. Kuumbwa zvidiki kunoratidza kuti zviyero izvi zvakakombama zvakasimba pamakero epasi zvekuti hazvigone kuonekwa nenzira yemazuva ese. Kunzwisisa kuti zviyero izvi zvinopesvedzera sei zviitiko zvemuviri munyika yedu inoonekwa ine mativi mana inzvimbo yakadzama uye inoenderera mberi yekutsvagisa.
Mabhanari: Zvinhu Zvine Hurefu Hwepamusoro
Pamusoro petambo dzakakosha, dzidziso yetambo inotsanangura zvinhu zvine mativi akakwirira zvinozivikanwa se "branes" (chidimbu che membranes). Branes dzinouya muzvikamu zvakasiyana-siyana, kubva pamapoinzi asina mativi kusvika kune zvinhu zvine mativi mapfumbamwe. Branes idzi dzinoita basa rakakosha mukuvandudzwa kwakawanda kwedzidziso, dzichishanda senzvimbo dzekupedzisira dzetambo dzakavhurika kana senzvimbo dzemhedzisiro yegiravhiti uye gauge field.
Ma-D-branes, rimwe remhando dzinonyanya kudzidzwa, akakosha mukugadzira mamodheru akawanda edzidziso yetambo. Anopa tsananguro yakatsiga yemhedzisiro isingakanganisike—iyo isingagoni kubatwa nenzira dziri nyore dzekuwedzera dzinokanganisa. Mune zvimwe zviitiko, muchadenga wedu unoonekwa unofungidzirwa kuti unogara pabhurane rine mativi mana mukati menzvimbo ine mativi akakwirira, nemamwe masimba akaganhurirwa kubhurane iri.
Maviri: Maonero Akawanda
Simba guru redzidziso yetambo ndiro dandemutande rezvinhu zviviri zvinobatanidza mafomu akasiyana-siyana edzidziso. Zvinhu zviviri kushanduka kwemasvomhu kunoratidza kuenzana pakati pedzidziso dzepanyama dzinoita sedzakasiyana. Kune zvinhu zviviri zvakakosha mudzidziso yetambo, zvinosanganisira:
1. T-Duality: Inoratidza kuenzana pakati petambo inopararira muchikamu chidiki chakamanikana netambo iri muchikamu chikuru.
2. S-Duality: Inobatanidza nzira dzakasimba nedzisina simba dzekubatanidza dzidziso dzakasiyana dzetambo, zvichiratidza kuti kudyidzana kwakasimba mune imwe modhi kunogona kuenderana nekudyidzana kusina simba mune imwe.
3. Kuenzana kweMirairo: Chimiro chinonakidza chehuviri umo zvidimbu zvakawedzerwa zvakamanikana zvine maumbirwo maviri ejometri asi zvichipa dzidziso dzepanyama dzakaenzana.
Dualities idzi dzinopa ruzivo rwakadzama, zvichiratidza kuti maitiro akasiyana-siyana edzidziso ye string—Type I, Type IIA, Type IIB, the SO(32) heterotic string, uye \(E_8 \times E_8\) heterotic string—hazvisi zvakasiyana asi zvakabatana pane chimwe chinhu chiri pasi pe framework.
M-Dzidziso: Mufananidzo Unobatanidza
Mamiriro edzidziso yetambo akasvika pakuchinja kukuru pakati pemakore ekuma1990 nekuuya kwedzidziso yeM. Ichinzi mufananidzo unobatanidza unosanganisira dzidziso dzese shanu dzinoenderana dzetambo, dzidziso yeM inoisa chimwe chinhu, ichikwidza huwandu hwenzvimbo dzenguva kusvika kune gumi nerimwe. Dzidziso iyi yakakura inoratidza kuti dzidziso dzakasiyana dzetambo ingori maonero epfungwa dzezvikamu gumi nerimwe dzakakosha.
Dzidziso yeM inosimbisawo kukosha kwemabrane, ane mamembrane (2-dimensional branes) nedzimwe nzira dzepamusoro-soro dzichiita mabasa akakosha. Kunyange zvazvo kuumbwa kwakazara kwedzidziso yeM kuchiramba kuri basa rinoenderera mberi, inomiririra danho guru rekuwana tsananguro yakakwana uye yakabatana yefizikisi huru.
Matambudziko uye Nhungamiro Yeramangwana
Pasinei neunyanzvi hwayo hwemasvomhu uye vimbiso yayo yedzidziso, dzidziso yetambo inosangana nematambudziko makuru. Imwe nyaya huru ndeyekushaikwa kwehumbowo hwekuongorora, chimwe chikonzero chiri chekuti zviyero zvidiki zvikuru zvinofungidzirwa kuti zvinoshanda pazviri. Kusimbiswa kwekuyedza kuchiri kusanzwisisika, uye kufanotaura kwakawanda kwedzidziso yetambo kunoda zviyero zvesimba kupfuura kugona kwehunyanzvi huripo pari zvino.
Uyezve, "nzvimbo" yakakura yemamiriro ezvinhu anogona kunge asina chinhu (mhinduro dzemaequation anotonga dzidziso yetambo) inoomesa kuedza kuwana fungidziro chaiyo. Nezvingangoita mamiriyoni emhinduro dzinoshanda, kuziva inoenderana nenyika yedu kwakafanana nekuwana tsono muhuswa hwepasi rose.
Asi, dzidziso yetambo inoramba ichikurudzira uye ichikurudzira tsvakurudzo itsva. Yakakurudzira kufambira mberi kukuru mumasvomhu, yakapesvedzera kudzidza kwegiravhiti yequantum, uye yakapa ruzivo rwakadzama mufizikisi yegomba dema uye rudzi rwenguva yemuchadenga. Pamusoro pezvo, kuedza kuri kuenderera mberi mucosmology, particle physics, uye kunyange condensed matter physics kunowanzo shandiswa pakushandisa maturusi edzidziso akapfuma akagadzirwa mukati mehurongwa hwedzidziso yetambo.
mhedziso
Dzidziso yetambo inomira sechiratidzo chekuda kuziva kwevanhu uye kutsvaga kusingaperi kwekunzwisisa hunhu hwechokwadi. Nekufunga patsva zvidimbu setambo dzinodedera uye kuongorora tambo yakaoma yehukuru hwepamusoro, kuenzanisa, uye huviri, dzidziso yetambo inopa chiono chinokwezva chepasi rose rakabatana. Kunyange hazvo kusimbiswa kwayo kwekupedzisira kungave kuri mune ramangwana, rwendo kuburikidza nedzidziso yetambo runoramba ruchigadzira nzira yefizikisi yemazuva ano yedzidziso, ichijekesa nzira dzinogona kutitungamira kune dzidziso isingawanikwe yezvinhu zvese.
