Something called "dark energy" which provides almost 70% of the total energy in the observable universe and is causing the expansion of the universe to accelerate (instead of decelerate as expected in the basic big bang model of the universe).

What percentage of universe are neutrons?

Neutrons are one of the three fundamental particles of an atom, along with protons and electrons. In the universe, neutrons make up a small percentage of the overall matter content, with estimates placing them at around 1% of the total mass-energy content. The majority of the universe is composed of dark matter and dark energy, which together make up the vast majority of its mass-energy content.


What are the things that make the universe?

The vast majority of matter in the universe is in the form of Hydrogen and Helium.


What are the main things that make up universe?

The main components of the universe are matter (including atoms and particles), energy, and the fabric of spacetime. These elements interact and give rise to everything we observe in the universe, including galaxies, stars, planets, and living organisms. Additionally, dark matter and dark energy are believed to make up a significant portion of the universe, even though they cannot be directly observed.


What are the currents theories of Cosmology?

Current theories of cosmology include the Big Bang theory, which posits that the universe began as a singularity and has been expanding ever since; the inflationary theory, which suggests that the universe underwent a rapid expansion in its early stages; and the concept of dark matter and dark energy, which are thought to make up the majority of the universe's mass and energy. These theories, along with ongoing research and observations, shape our understanding of the origins and evolution of the universe.


The mysterious force that may be causing the expansion of the universe to accelerate is called?

The current state of affairs with regard to the expansion of the universe point to dark energy as the cause of the expansion of the universe. It is not a force though.

What does most matter in the universe exist in?

Most matter in the universe exists in the form of dark matter and dark energy, which are currently not fully understood by scientists. These two components make up the majority of the universe's mass-energy content, with ordinary matter (protons, neutrons, electrons) making up only a small percentage.

What evidence supports the theory of a zero energy universe?

The theory of a zero energy universe is supported by the observation that the total energy of the universe appears to be balanced, with positive energy from matter and negative energy from gravity cancelling each other out. This balance suggests that the overall energy of the universe could be zero, allowing for the possibility of a universe that does not require any external energy source to exist.


What percent of the universe is made up of dark energy?

Dark energy -- whatever it turns out to be -- constitutes about 74% of the energy in our Universe.
