What is empty space made up of?

Perfectly “empty” space will always have vacuum energy, the Higgs field, and spacetime curvature. More typical vacuums, such as in outer space, also have gas, dust, wind, light, electric fields, magnetic fields, cosmic rays, neutrinos, dark matter, and dark energy.

What is the universe made of?

The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.

How many atoms are there in the universe?

Scientists estimate there are 10 80 atoms in the universe. Since we can’t go out and count each particle, the number of atoms in the universe is an estimate. It is a calculated value and not just some random, made-up number. The calculation of the number of atoms assumes the universe is finite and has a relatively homogeneous composition.

What is the mass of the known universe?

Mass of the Known Universe. A related number is the estimated mass of the universe, which is calculated to be 10 53 kg. This is the mass of atoms, ions, and molecules and excludes dark matter and dark energy.
