What does empty space consist of?
Atoms are mostly “empty space” and atoms (and their elementary particle building blocks) essentially make up ALL matter in the universe. Atoms contain almost all of their mass in a tiny nucleus at the center of the atom (like a marble in a soccer stadium).
Is space something or is it nothing?
Space can be measured and is therefore “something”, at least in my book. If “something” is your word for “matter” then space is nothing. You must first decide if there is indeed a “nothing” as you have described it. If there is nothing in the universe which could truly be considered “nothing” then the issue is moot.
What is empty space made of?
Space that we can see is mainly very very empty. If you ignore the galaxies and stars, then the rest of space is mainly a vacuum, so there’s no particles at all. The particles that are there are mainly hydrogen and helium, which form a plasma called the Intergalactic Medium.
What is the energy of empty space?
Specifically, the seed of the multiverse hypothesis is the inexplicably tiny amount of energy infused in empty space — energy known as the vacuum energy, dark energy or the cosmological constant. Each cubic meter of empty space contains only enough of this energy to light a lightbulb for 11-trillionths of a second.
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 empty space in physics?
Vacuum, a volume of space that is essentially empty of matter, such that its gaseous pressure is much less than atmospheric pressure. Free space, a perfect vacuum as expressed in the classical physics model. Vacuum state, a perfect vacuum based on the quantum mechanical model.
Are there atoms in space?
The deep vacuum of intergalactic space is not devoid of matter, as it contains a few hydrogen atoms per cubic meter.
