“HOW WE CAPTURED FIRST BLACK HOLE IMAGE?”

Namaskar dosto! Swagat hai apko hamare YouTube channel pe. Aj hum jis bishoy par bolne ja rahe hai WO hai “how we captured first black hole image?” Apko pata hai ‘black hole’ kya hai? Hum savime ye prasna rahte hai, kya wakai mai ‘black hole’ jaisa koi cheez hote hai? Kya Aizek Newton or Stephen Hawking ka theory black hole k bare me thik tha? Aiye pahle jante hai ye black hole kya cheez hai? Ji ha dosto, black hole is biswa brahmanda ka aisa cheez hai Jo sab kuch nigal lete hai. 

Sabse speed jiska hai jaise light isko vi nigal jate hai. Aj tak humne jitni vi Black hole ka taswir internet me dekhe hai wo sab editing hai. Per 10^th April, 2019 Scientist ne black hole ka taswir lene pe kamiab hua.  Lekin ye taswir lena kya mumkin hai? Jisme se light ray absorb nehi uska taswir kaise le ja sakta hai?  Ye black hole hamare prithwi se 27000 light-years k duri par hai. Isko M87 galaxy me paya gaya hai. Iska name “Sagittarius A” hai aur ye hamare solar 4 million guna bhari hai.

Iska high resolution taswir lena jaisa samudra ke pani me moti dhundna jaisa hai. Kyuki ye black hole humare prithwi se bahut bahut dur hai. Scientist ne single telescope se iska taswir nehi li. Uske 8 telescope ko ek black hole pe focus karke iska high resolution radio image ki. Par ye asan nehi tha. Is taswir ko lene pe 2 saal lage. Aur black hole ka jo data mila tha wo 10 lakhs GB ka tha. Ji ha doston ye koi mamuli sa kam nahi. Ye taswir lene ke time hamare prithwi k atmosphere vi bahut interrupt kiya. Asal me hum jo taswir dekha

 wo black hole nehi uska ‘Event horizon’ ka taswir hai. Jisme se light pass nehi hota   hum kaise wo pic le sakte hai? Hum uska shadow image dekhe hai.

At the end, mai Stephen Hawking k ek quote bolna chahta hu ki”It matters if you just don’t give up”. Ho sakta hai agar hum koshish jari rakhe toh ek din humko black hole ka image mil sakta hai.
