times more stars are there in universe compared to human eye can see
<h3><u>
Solution:</u></h3>
Given that, conservative estimate of the number of stars in the universe is 
The average human can see about 3,000 stars at night with only their eyes
To find: Number of times more stars are there in the universe, compared to the stars a human can see

Then from given statement,

<em><u>Substituting given values we get,</u></em>

Thus
times more stars are there in universe compared to human eye can see
