All-Star Basketball -NBA (Not Bound to Ask)‏

If you have a tough question that you can't answer, 

first tackle a simpler question that you can't answer.

Try this one,

One can fit 

as many basketballs inside the Earth

as there are stars in our visible Universe.

One can fit a million Earths 

in a volume the size of the Sun.

How many basketballs 

can you fit  inside  all the stars 

of our visible universe?

How much dark matter

there is in our visible universe?

How much dark energy 

there is in your invisible multiverse?
