do u know what is infinity.......?????
I was thinking that infinity is a number which is very larger than other all other number that time one question was arising in my mind that, when we multiply any no. to zero(0) then it's equal to zero(0) but when we multiply infinity to zero(0) then it not gives zero(0) it is undefined value.
Actually people also conceptualize infinity as a number that is larger than all other numbers, but it is not treated as a number in mathematics. it is represented a concept which has no boundation.

No. of Stars in our Universe
We all are thinking that the No. of stars are infinity in our Universe ,that's wrong.
Because stars are approximately countable so it's a value.you would so surprise to know that there are total 70,000 million million million stars in our Universe....(7 followed by 22 zeros)...It's also about 10 times as many stars as grains of sand on all the world's beaches and deserts. it's amazing na.There are approximate 10,000 galaxies in our Universe 20 billion stars are in our Milky Way Galaxies.
