(music plays)

In animation, a shooting star flies in space past planet Earth as a title appears: I wonder... WHY?

A boy pops up on screen. He has short black hair and glasses. His name is Felipe and a little girl stands next to him.

Felipe says HI, MY NAME IS FELIPE.
AND I WONDERED HOW
BIG THE UNIVERSE IS.

Damian Pope appears on screen. He is a perimeter scientist.

Damian says THANKS, FELIPE,
FOR YOUR QUESTION.
THE UNIVERSE IS
EVERYTHING THERE IS.
IT INCLUDES THE
ENTIRE EARTH,
ALL THE PLANETS IN
THE SOLAR SYSTEM,
ALL THE STARS IN THE
MILKY WAY GALAXY,
AND ALL THE MILLIONS OF
GALAXIES BEYOND THAT.
SO IT'S PRETTY BIG.
THE FASTEST WE KNOW
SOMETHING CAN TRAVEL IS LIGHT.
LIGHT GOES SO FAST IT
CIRCLES THE EQUATOR
SEVEN TIMES EVERY
SINGLE SECOND.
WHEN WE LOOK OUT INTO
SPACE, THE FARTHEST OBJECT
WE CAN SEE AWAY
IS SO FAR AWAY,
IT WOULD TAKE 45 BILLION
YEARS TO GET THERE
IN EVERY DIRECTION.

As he talks, an animated drawing shows the Earth as a tiny spec in space, and a long line reads “45 billion years.”

Damian says SO THE UNIVERSE
WE CAN SEE
IS 90 BILLION LIGHT
YEARS ACROSS.
BUT WHAT'S BEYOND THAT?
IS THERE A BRICK WALL?
DOES IT GO ON FOREVER?
IS IT JUST AN EDGE?
WE DON'T KNOW.
IT'S AN UNSOLVED MYSTERY
FOR FUTURE GENERATIONS
OF SCIENTISTS, LIKE
YOURSELF, TO SOLVE.

A big question mark appears on the screen.
