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

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?
