The universe is made up of the following three components:
- Matter (or baryonic matter): 4.6%
- Dark Matter: 24%
- Dark Energy: 71.4%
Do we know what the universe is made of?
What is the universe made of? The universe contains all the energy and matter there is. Much of the observable matter in the universe takes the form of individual atoms of hydrogen, which is the simplest atomic element, made of only a proton and an electron (if the atom also contains a neutron, it is instead called deuterium).
What does the universe need from US?
What does the universe need from us? The universe needs us to survive and help it evolve...to achieve widespread, conscious self-awareness that transcends the end of the universe.
What are some Wonders of the universe?
Some Wonders of the Universe :

What is the actual size of the universe?
The team thinks that the particle could be a type of loosely bound mesonic molecule (two subatomic particles called mesons bound via the strong force) or a tetraquark, a type of hadron composed of four quarks glommed together.
What is the universe mostly made of?
Composition. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the universe) and antimatter.
What are the 4 main components of the universe?
The universe encompasses all of space, time, matter, and energy. The universe contains everything that exists, from particles of matter smaller than an atom to the largest stars. The universe also includes all forms of energy, from the light you see streaming from stars to invisible radio waves and X-Rays.
What does the universe contain?
It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before the birth of the Universe, time, space and matter did not exist. The Universe contains billions of galaxies, each containing millions or billions of stars. The space between the stars and galaxies is largely empty.
What is the space made of?
Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.
How universe was created?
Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

What is bigger than the universe?
No, the universe contains all solar systems, and galaxies.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
What are the 3 types of universe?
There are basically three possible shapes to the Universe; a flat Universe (Euclidean or zero curvature), a spherical or closed Universe (positive curvature) or a hyperbolic or open Universe (negative curvature).
Does space ever end?
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.
What is nothing made of?
With no particles or antiparticles, no matter or radiation, no identifiable quanta of any type in your Universe, all you'd have left is the void of empty space itself. To some, that's the true scientific definition of "nothingness."
How did the life begin?
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.
What atoms did the universe form?
By roughly 380,000 years later, the universe had cooled enough for protons and neutrons to come together and form lithium, helium and the hydrogen isotope deuterium, while free electrons were trapped to form neutral atoms.
When did the universe start?
It all started with a Big Bang, about 13.8 billion years ago, when ultra-hot and densely packed matter suddenly and rapidly expanded in all directions at once. Milliseconds later, the newborn universe was a heaving mass of neutrons, protons, electrons, photons and other subatomic particles, roiling at about 100 billion degrees Kelvin, according to NASA .
Why did scientists discover dark energy?
The discovery of dark energy came about because scientists wondered if there was enough dark matter in the universe to cause expansion to sputter out or reverse direction, causing the universe to collapse inward on itself .
How much of the universe is helium?
Close to 5% of the universe's atoms are helium, according to NASA. Then, about 200 million years after the Big Bang, the first stars formed and produced the rest of the elements, which make up a fraction of the remaining 1% of all ordinary matter in the universe.
How many stars are there in 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 the most common element in the universe?
Hydrogen is the most common element found in the universe, followed by helium; together, they make up nearly all ordinary matter. But this accounts for only a tiny slice of the universe — about 5%. All the rest is made of stuff that can't be seen and can only be detected indirectly.
When was dark matter discovered?
Scientists first proposed the existence of dark matter in the 1930s, theorizing that dark matter's unseen pull must be what held together fast-moving galaxy clusters. Decades later, in the 1970s, American astronomer Vera Rubin found more indirect evidence of dark matter in the faster-than-expected rotation rates of stars.
What percentage of the universe is dark matter?
Here's what WMAP determined: Baryonic matter makes up a paltry 4.6 percent of the universe. Dark matter accounts for just 23 percent. And dark energy makes up the rest -- a whopping 72 percent [source: NASA/WMAP ]! Of course, measuring the relative proportions of the universe's building blocks is just the beginning.
What is the most fundamental unit of matter?
Astronomers classify all of this stuff as baryonic matter, and they (and we) know its most fundamental unit as the atom, which itself is composed of even smaller subatomic particles, such as protons, neutrons and electrons. (For simplicity's sake, we'll leave the leptons and quarks out of it.) Advertisement. Starting in the 1970s, astronomers began ...
How did scientists determine the mass of galaxies?
They did this by measuring the acceleration of clouds orbiting on the outer edges of a galaxy, which enabled them to calculate the mass required to cause that acceleration.
Is dark matter a particle?
Finally, dark matter could consist of a type of particle not yet described. These tiny bits of matter could exist somewhere deep in an atom and may be identified in one of the world's super-colliders, such as the Large Hadron Collider. Solving this mystery remains one of science's highest priorities.
Do black holes have luminous matter?
These starlike objects aren't luminous, but their intense gravity, which affects nearby objects, provides clues about their existence and location. Supermassive black holes could also account for the dark matter in the universe.
What are the three types of matter in the universe?
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.
What is the smallest proportion of the universe?
As humbling as it sounds, normal matter almost certainly accounts for the smallest proportion of the Universe, somewhere between 1% and 10%. In the currently popular model of the Universe, 70% is thought to be dark energy, 25% dark matter and 5% normal matter.
Why do galaxies emit lots of X-rays?
Clusters of galaxies emit lots of X-rays because they contain a large quantity of high-temperature gas. By measuring the quantity of X-rays from a cluster, astronomers can work out both the temperature of the cluster gas and also the mass of the cluster.
Do clusters of galaxies have more mass?
XMM-Newton. Theoretically, in a Universe where the density of matter is high, clusters of galaxies would continue to grow and so, on average, should contain more mass now than in the past.
Is the universe a high density environment?
This indicates that the Universe must be a high-density environment, contradicting current ideas. This conclusion is highly controversial, because to account for these results you have to have a lot of matter in the Universe and that leaves little room for dark energy.
Do clusters of galaxies give out more X-rays than expected?
Astronomers using ESA’s XMM-Newton have shown that clusters of galaxies in the distant Universe are not like those of today. They seem to give out more X-rays than expected. These clusters of galaxies have changed their appearance with time, and calculations also show that in the past there were fewer galaxy clusters.
