is most of the Universe so incredibly empty?

Look between the stars and galaxies, and something strange becomes apparent: despite billions of stars, enormous galaxies, and countless worlds, the overwhelming majority of space contains almost nothing at all.

But "empty" space isn't truly nothing.

In deep space, tiny amounts of matter are spread across enormous distances. There are scattered atoms, radiation, magnetic fields, cosmic dust, dark matter, and the ever-expanding fabric of spacetime. The distances are so extreme that even traveling at unimaginable speeds, crossing interstellar and intergalactic space becomes a profound challenge.

In this documentary, we explore the extraordinary emptiness of the cosmos through the lens of modern astrophysics and the scientific perspective associated with Neil deGrasse Tyson.

In this documentary, we explore:

Why most of the Universe is incredibly sparse
What actually exists between stars and galaxies
Why the vacuum of space isn't truly empty
How far apart stars really are
Why galaxies occupy only tiny regions of the cosmic volume
What interstellar space contains
How cosmic expansion increases the distances between galaxies
Why traveling through deep space is so difficult
How dark matter and dark energy fit into the cosmic picture
Why the emptiness of space is one of the most important facts about our Universe

The Universe isn't packed with matter the way our everyday experience might suggest.

Instead, it is dominated by enormous stretches of near-vacuum separated by relatively tiny concentrations of stars, planets, gas, and galaxies.

And that raises an unsettling question:

If almost everything in the Universe is empty space, why is there anything here at all?
