Cov lus nug ntawm seb puas muaj lub tshuab tshuab, yog kev txaus siab. Lo lus teb rau lo lus nug no feem ntau nyob ntawm qhov txhais tau hais tias lo lus "tshuab cav" thiab "muaj sia nyob."
Thiab qhov tseeb, tshwm sim, muaj thiab yuav muaj nyob - nws yog, qhov tseeb, tib yam, yog tias lub sij hawm cav ua tau tiag tiag. Tom qab tag nrho, lub sij hawm hloov mus ua nonlinear. Xws theories. Piv txwv, Seth Lloyd tau kho qhov nkhaus hauv qhov zoo li txoj hauj lwm ntawm tus photon nyob hauv nws tau xa mus tsis tau rau hauv qhov chaw, tiam sis hauv lub sijhawm. Thiab qhov no txhais tau hais tias, yam tsawg kawg, cov ntaub ntawv "lub sijhawm tshuab" muaj nyob.
Einstein hais li cas?
Nws, raws li koj paub, tsim txoj kev xav ntawm kev sib raug zoo . Raws li qhov kev xav ntawm no, nws zoo nkaus li tias cov lus nug txog seb puas muaj lub sij hawm siv lub tshuab yuav tsum tau txiav txim siab txog kev pom zoo ntawm nws lub neej hauv lub neej tiag tiag, thiab tsis nyob hauv Wells tus tshiab.
Thiab Einstein tau suav hais tias lub sij hawm tsis zoo li ib yam dab tsi, tiam sis yog qhov dav ntawm plaub qhov chaw. Tsuas yog, qhov no txhais tau hais tias nws muaj qhov "ceev ceev plaub" ntawm qhov khoom, thiab rau cov khoom uas tsis yog tsiv (tom qab so), nws yog sib npaug zos rau qhov ceev ntawm lub teeb. Tab sis yog tias qhov khoom txav, qhov sib npaug ntawm nws cov velocities (peb-dimensional thiab plaub-dimensional) tseem yog sib npaug rau cov kev khiav ntawm lub teeb, uas txhais tau hais tias qhov ceev cov khoom txav rau hauv qhov chaw, nws qeeb nws tsiv lub sij hawm. Thiab yog hais tias qhov peb-qhov dav tshaj tawm qhov ceev ntawm lub teeb, ces qhov kev kub ceev hauv lub sijhawm lej xoom. Qhov no yog lub txiaj ntsim nto moo ntawm lub sij hawm dilation, uas cov ntawv sau txog kev tshawb fawb nyiam nyiam tham txog. Zoo, li cas cosmonauts leej twg rov los ntawm lub davhlau tsis paub cov ntsej muag: lawv cov phooj ywg twb tuag lawm laus laus . Nws puas yog lub sijhawm tshuab?
"Qhov" thiab "wormholes"
Thiab Einstein pom tias lub sij hawm nyob ntawm lub ntiajteb txawj nqus: nyob ze lub cev loj nws ntws qeeb qeeb. Li no, xyov distorting qhov chaw, ib yam li lub ntiajteb txawj nqus, koj muaj peev xwm tsim "qhov" los ntawm nws. Tom qab ntawd, nyob rau hauv qee qhov kev mob, nws yuav ua tau kom muaj kev sib raug zoo thiab tau tawm ntawm "burrow" ua ntej koj mus rau qhov ntawd. Thiab qhov no tseem ceeb heev. Ntawm no tsuas yog Einstein
Lwm txoj hauv kev nkag siab seb puas muaj lub tshuab siv sij hawm, txuas nrog cov qhov dub thiab cov tswvyim hais ua dab neeg lossis kev tseeb, kuj tsis meej meej. Nyob rau hauv txhua rooj plaub, nws yog ntseeg hais tias qhov chaw Giants, tuag, yog compressed. Tab sis qhov teeb meem tsis mus qhov twg, tab sis dhau mus ua ib yam dab tsi me, tab sis ntawm tib pawg. Ntawd yog, lub ntiajteb txawj nqus ntawm qhov khoom zoo li no zoo kawg nkaus. Obviously, qhov chaw ntawm no thiab yuav tsum tau bent chaw, cia tawm rau frolic lub sij hawm, tab sis qhov no yog unprovable. Nws tseem tsis yooj yim sua kom coj kom zoo dua li lub sij hawm "tshuab tshuab": ua ntej ncav cuag lub qhov dub, ib tug neeg yuav tawg ua ib pawg ntawm cov pob zeb loj (monstrous gravitation) ntawm cov qauv.
