Assalamu Alaikum bhai era, kemon achen sobai? Ajke ekta interesting topic niye kotha bolte chai - mohakaash biggan. Choto bela theke amader sob kokhono na kokhono akasher dike takiye vebechilam, ei tara gulo ki, chand ta koto dure, ar amra ei bishal universe er kothay achi. Inshallah ajke ei bishoy ta niye ektu detail e alochona korbo.
Prothomei boli, amader prithibi ta asolei koto choto ekta jogho ei mohakaashe. Surjo theke prithibi er dura praye 150 million kilometer, kintu eta to khub kachei bola jay. Amader nearest star Proxima Centauri ta praye 4 light year dure, mane light er speed e geleu 4 bochor lagbe pouhchate. Mashallah, ei scale ta chintar bahire na? Ami first time jokhen ei calculation gulo porlam, literally mind blow hoye gechilo. Dhaka theke Chittagong ta 250 km mone hoy onek dure, kintu space er tulonay eta kichu na.
Space exploration er history ta besh interesting. 1957 te Soviet Union er Sputnik 1 diye shuru, tarpor 1969 te Apollo 11 mission e manush prothombar chand e paa dilo. Ekhon to private companies o space e jachhe. Amader South Asia thekeu India er ISRO aro Bangladesh er own satellite Bangabandhu-1 launch hoyeche 2018 te. Ami personally khub proud feel kori jokhen shuni amader desh o space technology te agaiche. Probashi theke jokhen ei news payi, alhamdulillah bhalo lage.
Ekta common proshno holo - alien ache ki nai? Honestly bhai, universe ta eto boro je mathematically dekhle mone hoy thaka uchit. Kintu ekhono kono confirmed evidence paoya jay nai. Drake Equation bole ekta formula ache je estimate kore koto intelligent civilization thakte pare, kintu eta purely theoretical. Ami personally believe kori Allah jodi chayen, ekdin hoyto amra janbo. Science ar faith duitai ekshathey thakte pare.
Shesh e bolbo, mohakaash biggan shudhu rocket ar satellite er kotha na. Eta amader shikhay je amra koto choto, kintu shathey shathey human curiosity koto powerful. Apnader karo jodi ei topic niye interest thake, YouTube e Veritasium, Kurzgesagt er videos dekhte paren, khub bhalo explain kore. Bangla te o onek content ashche ajkal. Kono proshno thakle comment e janan, try korbo answer dite. Dhonnobad sobai ke, Allah hafez! 🌟
