What fills the empty space in the universe?

Space is not empty. A point in outer space is filled with gas, dust, a wind of charged particles from the stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and magnetic fields, and neutrinos from nuclear reactions.

What fills up the universe?

The universe is filled with billions of galaxies and trillions of stars, along with nearly uncountable numbers of planets, moons, asteroids, comets and clouds of dust and gas – all swirling in the vastness of space.

What is inside empty space?

This point is light years from Earth, vastly distant from any nebula, star or lonely atom. We have many words for what you would find in such a place: a void, a vacuum, a lacuna. In fact, this nothingness is a sea of activity. According to quantum theory, empty space is filled with virtual particles.

How much of the universe do scientists think is just empty space?

99.9999999 percent
Maybe you have a lot of friends, or an important job, or a really big car. But it might humble you to know that all of those things – your friends, your office, your really big car, you yourself, and even everything in this incredible, vast Universe – are almost entirely, 99.9999999 percent empty space.

What elements make up empty space?

While hydrogen and helium make up most of the gases in interstellar space, tiny traces of other elements such as carbon, oxygen and iron also exist. Scientists who study interstellar space use spectrometers to identify trace amounts of other molecules between the stars.

What do scientists believe matter is made up of?

The familiar material of the universe, known as baryonic matter, is composed of protons, neutrons and electrons. Dark matter may be made of baryonic or non-baryonic matter. To hold the elements of the universe together, dark matter must make up approximately 80\% percent of the universe.

What is the empty space in the universe?

The universe appears to be empty, but on quantum level the empty space is actually filled with things like quark and gluon field fluctuations, dark matter, and dark energy.

What can we learn from the empty space?

Going deeper into the empty space of atoms may eventually reveal the secrets of the Universe and provide a better understanding of the laws of physics. Outer space is not the final frontier. We are only now discovering an endless world within the emptiness of everything in our Universe.

What is the majority of the universe made of?

However, most of the universe is what we think of as empty space. All the atoms together only make up around four percent of the universe. The majority of the universe consists of something scientists call dark matter and dark energy. What are dark matter and dark energy?

Does the universe have enough energy to stop its expansion?

Dark Energy, Dark Matter In the early 1990s, one thing was fairly certain about the expansion of the universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on.
