Gravitational Waves: when black holes are Mittu aunt's Ladoos!!
Suppose… ...you have two ladoos in hand. You weighed each and found one 8 and the other 12 grams. Now, you want a bigger ladoo from those two and, wuhooo!, here I am with a glowing bulb over my head and helping hands. You hand them over to me, and I crush them both and mould the crumps of both ladoos together making a bigger ladoo for you. But, as you weigh the bigger ladoo I just made, you find it to be 17 gram. 12 + 8 = ???! Haa, yes, there arises a question on the missing 3 gram! So, what yeh gonna do? Huh! Blame me?? Nah, I didn’t - I didn’t eat it. Okay, so what’s the matter? Consider these ladoos to be black holes . Yeah, I mean it. Such a case was found with black holes as well. It was found that two black holes of solar masses 36 and 29, collapsed not to form a black hole of 36 + 29 = 65 solar mass, but of 62 solar mass. The missing 3 solar mass here went into the production of gravitational waves. And, that was the birth of gravitational wa...
