How big is the universe?

This is a question we humans cannot answer.   Because there might be no boundary for this universe.   If you are able and if you can manage to go to the edge of the universe,   you can be sure that there will be an "outside" for your boundary.

You can create a story for this beginning.

You can create a hero who can fly extremely fast.

When your hero arrive the boundary of this universe,  he will be puzzled:  "Well,  am I supposed to reach the boundary?"   And he will be further puzzled that he is only at the beginning.

There will be some beginning, but there will not be any ending.

Every point can be a beginning point.  But there is no ending point.

Humans believed they can measure themselves.  Humans invented measurements.  Humans said they know how big is the earth.  

But the measurement might be meaningless.

Because measurement comes from compare.   You can only measure something against another something.   For example, you can use a ruler to measure.  But you can never know how big is your ruler.

Maybe one inch is one million mile in the eyes of the universe measurement.   You never know.

If you stand up, you might be as high as the moon.  Because all measurements are only temporary.  It is not true.

Now can we find the answer for the question?

How big is the universe?

Yes, you can have an answer like this:

Wow, it is really big.

How big is it?

Well,  it is very, very big.

(And then you stretch your arms wide open to show it.)

Then everyone is satisfied.
