Question

If the earth was the size of a golf ball how big would the universe be?

Answer 1

Hint : Our earth is big but how big is it really compared to our Sun, the most notable star around us. The earth is actually quite small as compared to the Sun. Our Sun is almost $1.4$ million kilometers in diameter while our earth is only $12,742km$ in diameter which is a big difference. Since it is difficult to visualize things at this scale, thus we shall shrink things down making our earth the size of a mere golf ball.

Complete step-by-step solution:
We have taken our earth to be of the size of a golf ball. At this scale, the Sun would be over $15$ feet wide and we would be able to fit $1.3$ million golf ball-sized earths inside of it. That is enough golf balls to completely fill two school buses.
Even huge stars like Canis Majoris are only one of the hundreds of billions of stars in our galaxy and our galaxy is only one of the now believed to be over two trillion galaxies that make up our universe.
Therefore, it is unimaginable enough to comprehend the size of the universe even if the earth was shrunken down to the size of a golf ball.

Note:
Our Sun is a tiny star. In fact, there are many much larger stars in our galaxy. For example, Arcturus is a star that measures over $36$ million kilometers wide. If we bring it down to scale with respect to our golf ball-sized earth, Arcturus would be wider than a football field and $22.6$ billion earths could fit inside of it.
