Kum 340 BC ah Aristotle-in a lehkhabu 'On the Heaven' ah kan lei hi a zawl duai ni lovin a sawl deuh va, a mum deuh bawk ani, a ti a! Ani bakah Ancient Greek ho kha he ngaihdan lamah hian anlo kal thui tawh em em a. Mahsela kan Earth hi a lai takah awmin Planet leh Ni te hian an hual vel ani, a ti thin thung! Earth hi kan Solar system ah a centre lo anih tih tuman 1514 hmalam ah anla hrelo, Polish puithiam Nicolas Copernicus chuan ngaihdan danglam deuh neiin 'Earth hi a lai takah awm lovin Ni zawk hi a awm zawk a; Tin, Planet leh Earth te hian an vir hual zawk a ni' arawn ti a! Ani model siam hmang hian John Kepler leh Gallileo te pawhin idea thar an siam chhuah belh leh a; John Kepler chuan Copernicus-a sawi Ni kan helna kawng ‘orbit’ hi a mum pup lova, elliptic zawk ani, a ti a! Chutih lai vekin Gallileo pawhin planet te hian Ni hi an hel satliahlo tih Jupiter a zirchianna aṭang a hmuchhuak bawk!
Kum 1687 alo chuang kai a, Khawvel a scientific law hmuhchhuah zinga ropui ber mai hmuchhuaktu Isaac Newton alo chhuak a. Ani chuan a hmalam a mithiam te ngaihdan lachhawngin a tidanglam bawk a. Chungho thlunkhawm nan chuan khawvel a pawimawh em em 'Gravitational Force' hi arawn thehchhuak ta a ni. Tin, chung te chu 'motion' chithum ah hman annih dan arawn sawifiah bawk a. Isaac Newton's Law pathum te leh Gravity te hian a hunlai mithiamte ngaihdan a siamchhuah sak dan ah Planet te hian Ni hi Gravity avangin kan hel a; chung gravity pahnih te chu Repulsion leh Attraction te an ni a. Tin, mass nei tam a piang ah force a chak a. Distance nei tlem a piangah a chak bawk tih ani a.
Tichuan kum 1929 alo ni a, Star te hlat zawng teh tum tlat mi pakhat Edwin Hubble-a tihdan arawn chhuak ta a. A ngaihdan ah chuan Arsi te hi an hlatzawng teh theih niin a ngai a. Chumi Model atan chuan Newton Laws of Reflection kan tih mai thin kha a hmang a. Chu chu tuna Chhimbal(Rainbow) kan hmuh ang te pawh hi a ni a; Ni in kan Earth arawn sut dawn reng reng hian atmosphere an kaltlang na lamah spectrum an pe chhuak ṭhin a, chu chu Physics a lar em em 'Dispersion of Light’ kha a ni. Chumi hmanga Star te hlat zawng kan teh dawn chuan star atanga 'êng' lo chhuak hrim hrim hian blue shift hi kan lei an rawn thlen hian an rawn siam a. Nimahsela chumi chungchang a hmuh chhuah zingah 'red shift' a awm ve tlat chu Hubble a buaina a ni! Heivang hian Droppler's Effect, Police hovin motor speed an tehna a an hman thin hman alo ngai ta a. Droppler's Effect ah chuan motor speed tehna chu an engine sound cham rei zawng leh cham reiloh zawngah a innghat a. Chutiang chiah chuan Arsi te hian 'Blue Shift' bakah 'Red Shift' an lo pek ve hian an awmna original position ata an hla tial tial tihna alo ni a. Tichuan, Hubble chuan Arsi atang a eng lokal ‘blue shift’ te chu reilo te ah ‘red shift’ ah an chang ve leh nghal zel thin tih a hmuchhuak bawk a! Chumi awmzia chu arsi te chu an hla tial tial a, an rawng pawh 'blue' aṭang 'red' ah a inthlak tih a hriat theih ta a ni. Chung zawng zawngin a tihchian leh zual chu kan Universe hi a zau mek (expanding) a ni tih hi a ni!

Newton Law hi Hubble's Observation ah vawm kai ila, Universe past history hi kan hre thei a nga; chutiang bawkin a future pawh kan hre thei tawh dawn bawk a ni. Newton 1st Law chu kan han vawm kai ta ngei a, thil engpawh a chet chuan a chet tanna- initial state a awm a ngai ta a. Chu chu Universe zau mek a kan hmehbel chuan kan Universe hi hman ah chuan ala zau miah lova nga, a te hle a nga, point chhunhan khat tiat lek ani a nga; chutiang a nih chuan motion avang a space-time lo awm ta pawh hi a te hle dawn avangin a awm dawn miah lo va. Universe ber a chu singularity anih tawh dawn miau avangin eng force leh energy mah a awm thei tawh dawn lova. Keimahni pawh hi kan awm dawn miah lova! Kan 'consciousness' tuna he Universe nena inthlunzawm tlat pawh hi a awm dawn miah lo bawk a, a awm miau loh chuan kan ngaihtuahna a Pathian awm ṭhin pawh hi a awm thei dawn miah lo tihna a ni bawk ang.
Entirnan, 'Age of Reason' lehkhabu Thomas Paine ziak i lei a. I chhiar dawn a. A kawm i keu hawn chiah khan a chhung thu awm alo lang ṭhin ang hi a ni. Lehkhabu hi Singularity nita sela, lehkhabu kawm i keu tam tial tial kha Expanding Universe nita bawk sela. Tichuan Singularity aṭanga Expanding Universe alo thlen ve leh nang leh kei kan lo awm a, ngaihtuahna leh consciousness hi alo awm ta chiah bawk- lehkhabu kawm kan keuva a chhung thuziak alo lang ang chiah hian!
He lehkhabu hi keu miah lova a chhunga thu awm i hmuin i ngaihtuah thei miah lova nga, I hre dawn heklo. Chutiang chiah chuan kan Universe hi singularity aṭang Expanding Universe hi nita lo se, he electric field, magnetic field kan tih te, kan consciousness leh mind te pawh hi alo awm dawn miah lo tihna a ni a. Consciousness leh Mind a awm miau loh chuan kan ngaihtuahna leh rilru a 'Pathian ka mitthla fo pawh hi a awm dawn miah lo tihna ani bawk ang! Tichuan, Universe History Physical Laws hmanga kan siam hi a dik a nih chuan..Pathian hi a awm lo chiang ani tih hi a fiah thawkhatin a dik tlat!
