New year vacchindi kada. 12 o clock daatangane manam raka rakalu ga celebrate cheskunnam, cakes kosam, dance chesam, tapakayalu kaalcham, pakkanollani kaugalinchukunnam.
Aithe ee celebration manam enduku cheskuntunnamo kada ani bill katti UBER lo intiki vachetappudu naku anipinchindi.
Ala teerikaga alochinchagaa, thoughts etoo vellipoyayi. bhumi entha dooram tirugutundi kada mana suryudi chuttu. asalu aa cosmic distances alochiste entha fast ga tirugutundo kada anipichindi. inka alochinchaga, suryudi chuttu manam sare, mana suryudu kuda mana galaxy chuttu tirugutunnadu kada ani gurtuku vacchindi. mana solar system sare, mana galaxy kuda ee akhanda bramhandamlo vipareetha vegam tho tirugutundi kada ani gurthukocchindi.
Nijame kada, bhumi suryudi chuttu 58 kotla kilometers tirugutundi oka samvatsaram lo. http://www.physlink.com/education/askexperts/ae548.cfm
Aithe speculations prakaram mana solar system, adi unde galaxy antha mana bramhandamlo 1870 kotla kilometers dooram velutundi anta.
So oka average manishi tana average ga oka samvatsaram lo 1870 + 58 = 1926 ante approx 2000 kotla kilometers tirugutaadu anamata. ikka paiga nenu mana solar system mana galaxy chttu pradakshnam cheyadaniki entha dooram vedutundo calculate cheyaledu.
So Amma, mana jeevitham lo travel chesina distances tho compare cheste nenu ekkuva dooram emi vellaledu. pakkane unnanu. just 14,000 kilometers aee.
Idantha sare,
Asalu bhumi enduku tirugutundi?
mana bhumi asalu gudranga enduku undi? ani doubts vacchayi naku.
ee roju ee rendu points discuss cheddar ani ankuntuannanu
why is the earth round?
what is round
round is actually sphere.
round is more or less a circle.
sphere ante golakaram antaru telugulo. golakaram ki unna speciality enti ante, danni madhyam ninchi daani bahyam ye disha lo chusina okate dooram untundi.
ante daani centre point ninchi daani external surface ye direction lo chusina okate distance untundi anamata. https://en.wikipedia.org/wiki/Sphere
so manaki ippudu golakaram ante ento telusu kabatti ippudu aa aakaraniki mana bhumi ki enti sambandham anedi telusukundaam.
aithe manaki bhumi gurinchi telusukovali ante mana universe gurinchi mundara telusu kovali? approximate ga13 billion years mundara form ayyindi. 1300 kotla samvatsarala kritham anamata.https://en.wikipedia.org/wiki/Big_Bang
form ayyinappudu oka chinna point ninchi mottham universe form ayyindi anukundaam. form avvagane antha oka rakamaina dummu laaga form ayyindi anukundam. So motham antha vedi pogalu ga modalaindi. ippudu vedi pogalu melliga challabadatam modalu pettayi anamata. challa badutunnappudu poga kaasta dravam laaga tayaru ayyi. dravam kaasta ghanam ga tayaru ayyindi. ghanam ante solid, dravam ante liquid. ee ghanam kaasta melli melliga deggaraku raavadam modalaindi. enduku deggariki vachindi ante? adi anthe anamata analsi vastundi nenu. adi anthe enduku ante, baruvu unna prathi padaardhaniki gravity untundi anamata - gurutvaakarshana. ee aakarshana moolanga melli melli ga dummu kaasta raalla laaga form avtundi anamta. https://en.wikipedia.org/wiki/Gravity
eppudaina mana illu oodchukokapote ikkada akkada padina dummu juttu anni kalisi chinna muddala laaga tayaru ayyi oka moolaki tayaru avutayi eppudaina gamaninchara? ee chinna raallu kuda alage form avtayi anamata. vandalakoddhi samvatsarala lo. oka dhuli renuvu meeda inkoka renuvu. melli ga ala raallu pedda pedda kondalu ga marayi. continuous ga oka raayi inkoka raayini aakarshistu. Ayithe ikkade mana rahasyam undi anamata. oka raayi daani chuttupakkala unna raalla ni anni directions lo okate force tho attract chestundi anamata. anni directions lo okate aakarshana undatam vallana anni directions ninchi raallu vachi ee modati raayi ki attukkuntu untayi. atukkunedi anni directions ninchi okate vidham ga attukuntu untayi. ila velaa samvatsaralalo anni veypula ninchi raallu raallu aakarshitam ayyi oka golam ga maarutundi anamata. andukane mana chuttupakkala anni planets kuda spherical ga ne untayi.
ee concept ki inko example enti ante manchi neeru. oka neeti bottu ye roopam lo untundi? manam usually drawings lo depict chesetappudu spheroid or droplet shape. pointed top and spherical bottom. ee droplet or neeti chukka ni kanaka space lo odileste kanaka actually perfectly spherical ga untundi. idi enduku ante cohesive forces valla anamata. oka neeti molecule inko neeti molecule ni attract chestu untundi. anni oka chota undali ante energetically safest shape vachi spherical shape anamta. cube shape lo or cylinder shape lo unnappudu gravitational energy lowest state lo undadu.
ee lowest state enti ra babu ippudu anacchu meeru. idi ela ante universe mottham oka pedda peenasi candidate anukundam. universe ki energy anedi dabbu lantidi. eppudu chusina entha takkuva energy kharchu pettagaligithe anthe takkuva energy kharchupedutundi anamata. enduku alaga ante daaniki oka point taravata explanation undadu. enduku ante ee universe lo ee set of rules manaki establish ayyi undi kabatti. vere universe vere riules undacchu. for all we know.
so ee lowest energy model prakaram oka padardham ki best shape enti ante spherical or golakaram anamata. ee reason valla bhoomi golakaram lo untundi.
ee sodhi antha sare bhumi enduku tirugutundi nayanaa??
bhoomi tirugutundi sare, meeku andaraki bhoomi ye disa lo tirugutundo telusu kada? north pole paina ninchi chuste anti-clockwise tirugutundi. or west to east tirugutundi. OK?
ippudu meeku mind blowing vishayam okati cheppana? mana solar system lo, anni grahalu west to east ae tirugutayi. anni grahalu matrame kaadu mana suryudu kuda west to east ae tirugutaadu. exceptions vachi venus inka uranus. (https://www.scientificamerican.com/article/why-venus-spins-the-wrong/)
aithe deeniki kaaranam enti ante indaka cheppanu kada dhuli renuvuu melliga oka daanini okati attract avvukuntuoka direction lo tiragadam modalaitayi. ivi tiragadam ela modaliatayi ante id imagine chesukondi. meeru oka friend opposite directions lo parigettukuntu vastunnaru. iddari chetulu baitiki jaapi unnayi. okariki okaru konchem edam ga unnaru. parigettukuntu okarini okaru pass avva botunnaru. ippudu chetulu pattukunnaru. em jarugutundi? okari chuttu okallu tiragadam modalu pedataru. mee friemd kanaka meeku left ki unte, meeru anticlock wise direction lo tirugutaru. ade right side unte clockwise lo tirugutaru. so imagine chesukondi, okkokka dhuli renivi first time inko renuvu deggariki vellinappudu, aa modati renuvu rendava renuvu ki left side lo undindi anamata. manaki bhumi meeda aithe friction untundi, gravity vallana, gaali vallana, neella vallana etc. aithe space lo resistance or friction anedi undadu. so okasari tirgadam modalu aithe inka aagedi ledu ala tirugutune untundi newtons first law of motion. https://en.wikipedia.org/wiki/Retrograde_and_prograde_motion
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
imagine cheskondi the extent of it. modati renuvu oka direction lo tirgadam vallana mottham bhumi vere grahalu mana suryudu anni okate direction lo tirugutunnaryi ee roju. asalu entha adbhutam kada? https://en.wikipedia.org/wiki/Rotation_period
aithe meelo kontham mandi anacchu adenti space lo kuda vere planets untayi kada, avi gravity exert cheyachu kada vere objects meeda? daani vallana oka vidhanga resistance or friction untundi kada? aithe deeni valla ne venus and uranus vachi vere directions lo tirugutayi. recent speculations prakaram, ivi okappudu manam tirugutuna direction lo ne tirigevi ante, kotla samvatsarala kritam ivi aagi vere disa lo tiragadam modalu pettayi. pedda explanation undi, adi manam ee podcast lo discuss chesukomu.
Aithe going back to mana bhumi enduku gundram ga untundi ane prasna ki, bhumi perfect gundram aa? kaadu kada. mana himalayalu antha paiki untayi and mana samudralu anthe lothu ga untayi. Paiga mana bhumi equator deggira 43 km ekkuva diameter untundi pole to pole compare cheste. http://www.universetoday.com/25893/is-the-earth-round/
kani oka billiard ball tho compare cheste kanaka biliard ball gundram ga untunda mana bhumi gundranga untunda??
Answer vachi mana bhume gundranga untundi. so billiard balls tayaru chese tappudu 0.22% error ki chance istaru anta, mana bhumi aa model tho compare cheste within 0.15% error in sphericity lo undi. That is amazing.
so ivalla bhumi enduku gundranga undo and enduku tirugutundo telusu kunnam kada. wonderful. vache saari inko interesting topic tho mee munduku vastam. tata goodnight bye bye
