Scientists have long been studying the composition of the universe, and have found that only about 1% of the universe is composed of matter that we can see, touch, and interact with. This matter, which includes everything from stars and galaxies to people and planets, is made up of the building blocks of atoms, which in turn are made up of protons, neutrons, and electrons.
The other 99% of the universe is made up of what is known as dark matter and dark energy. These two phenomena are still not fully understood, and while scientists can detect their effects on the known universe, they cannot observe them directly.
Dark matter is believed to be a type of matter that doesn’t interact with light or any other form of electromagnetic radiation, which makes it impossible to see or directly detect. Instead, scientists infer its existence based on gravitational effects it has on visible matter, which includes the way it influences the motion of stars and galaxies.
Dark energy, on the other hand, is believed to be a force that is causing the universe to expand at an accelerating rate. Again, it is not directly observable, and scientists infer its existence based on its effects on the known universe.
Both dark matter and dark energy are believed to be among the most fundamental and mysterious components of the universe. Studying them remains one of the biggest challenges in modern astrophysics and cosmology. While we still have a long way to go in fully understanding the universe, recent discoveries and breakthroughs have brought us closer than ever before to unlocking some of its secrets.

Does plasma make up 99 percent of universe?
No, plasma does not make up 99 percent of the universe. While plasma is the most common state of matter in the observable universe, making up about 99 percent of the visible matter in the universe, it only represents a small fraction of the total matter in the universe. In fact, plasma only makes up about 0.2% of the total mass-energy content of the universe, with the remaining 99.8% made up of dark matter and dark energy.
Dark matter, which is thought to be composed of as-yet-undiscovered particles, is estimated to make up about 27% of the total matter in the universe. This matter, while invisible and undetectable through normal means, has been observed to affect the motion of galaxies and other cosmic structures, leading scientists to conclude that it must exist in some form.
Dark energy, on the other hand, is a mysterious force that is causing the expansion of the universe to accelerate, in opposition to the gravitational pull of matter. It is currently estimated to make up about 68% of the total mass-energy content of the universe, and its nature and properties are still largely unknown.
So while plasma is certainly an incredibly abundant state of matter in the universe, it is only a small part of the larger picture when it comes to the overall composition and structure of the cosmos.
What contains 99% of matter in the solar system?
The majority of the matter in the solar system is concentrated in the Sun, a massive, nearly perfect sphere of hot plasma in the center of the solar system. The Sun is by far the largest and most massive object in the solar system, and it contains more than 99% of the total mass of the solar system.
In addition to the Sun, the other major components of the solar system include the eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) and their moons, as well as numerous asteroids, comets, and other small bodies.
Of the planets, Jupiter is the largest, with a diameter more than 11 times that of Earth, and it also contains the most mass of any planet in the solar system aside from the Sun. Together, the eight planets contain only a tiny fraction of the total mass of the solar system, accounting for less than 0.2% of the total.
In addition to the planets, the solar system also includes a vast number of smaller objects, including asteroids, meteoroids, and comets. These objects are thought to be remnants of the original solar nebula from which the solar system formed, and they are scattered throughout the solar system in a wide range of orbits.
The total mass of these smaller objects is estimated to be only a few percent of the total mass of the solar system.
Taken together, the Sun and the planets make up the overwhelming majority of the matter in the solar system, with the Sun alone accounting for more than 99% of the total mass. This concentration of matter in the central star is a defining characteristic of our solar system, and it has played a crucial role in shaping the evolution of the planets and other objects in the solar system over billions of years.
Is the universe a plasma?
No, the universe is not considered to be completely made up of plasma, although it does contain a significant portion of ionized gas, which is the most common state of matter in the universe. Plasma is a state of matter where free electrons and ions coexist due to the high energy of the particles. It is often referred to as the fourth state of matter after solid, liquid, and gas.
In fact, plasmas account for more than 99% of the observable universe.
The most well-known examples of plasma in the universe are stars and their associated coronae, which are hot, ionized gases composed primarily of hydrogen and helium atoms. The plasmas found within stars are maintained by high temperatures and pressures generated by the fusion of atomic nuclei. Other examples of plasmas in the universe include supernova remnants, planetary magnetospheres, and the interstellar and intergalactic medium.
However, while plasmas are common in these areas, they are not the only state of matter present. There are also regions of neutral gas and dust that coexist with ionized gases. Additionally, some regions of the universe are too cold or too dense for plasmas to form, and so they are composed of other states of matter.
While plasmas are common in the universe, the universe is not considered to be entirely made up of plasma. There are regions where other states of matter, such as solids, liquids, and neutral gases, dominate. However, plasmas do make up a significant portion of the matter in the universe, and understanding their properties is crucial to understanding the behavior of stars, galaxies, and other structures in the cosmos.
Does plasma make up all stars?
No, not all stars are made up of plasma alone. While it is true that plasma is one of the four fundamental states of matter and is the most common state of matter in the universe, stars are composed of a variety of different elements including hydrogen, helium, carbon, nitrogen and oxygen. These elements combine to form the different layers that make up the interior and atmosphere of a star.
While stars are hot enough to ionize the gas of which they are composed, plasma only exists in certain areas and under specific conditions within a star. For example, the core of a star, where nuclear fusion takes place to convert hydrogen to helium releases a tremendous amount of energy in the form of electromagnetic radiation which can ionize the gas in its surroundings creating a plasma.
The outer layers of some stars, such as the sun, also contain plasma due to the intense heat generated through the process of fusion.
However, not all stars are hot enough to ionize their gas, and therefore do not contain plasma. For example, red dwarfs, which are some of the coolest and most common stars in the universe do not emit enough energy to ionize their gas or produce a plasma.
Plasma does play a significant role in the composition of some stars, but it is not the only factor determining their makeup. Other factors such as the chemical composition and temperature of the star also influence its structure and behavior.
When did the universe stop being plasma?
The universe stopped being plasma around 380,000 years after the Big Bang. Prior to this time, the universe was in a state of extreme heat and density as its temperature was in the range of 10^9 to 10^12 Kelvin, and all matter existed as ionized plasma. This period is commonly known as the “cosmic Dark Ages,” as no light or electromagnetic radiation could travel through the dense plasma.
As the universe continued to expand and cool, the energy density of the plasma decreased, and electrons combined with protons to form neutral atoms. This process is known as recombination. Recombination occurred when the temperature of the universe dropped below 3000 Kelvin, allowing atoms such as hydrogen and helium to form.
Once recombination was complete, the universe was left transparent, and light could finally travel freely through space.
Therefore, it can be said that the universe stopped being plasma around 380,000 years after the Big Bang when recombination occurred, and the plasma transformed into neutral atoms. This event is crucial as it marked a significant milestone in the evolution of the universe, laying the foundations for the formation of stars, galaxies, and ultimately, life.
Is plasma the 4th matter?
Yes, plasma is the fourth state of matter, with the other three being solid, liquid and gas. Plasma describes some matter made up of extremely hot ionized gas. It is sometimes referred to as the “fourth state of matter” and occurs naturally in stars, lightning and also in some fluorescent and neon lights.
Plasma is often referred to as an ionized gas and consists of a mixture of electrons, ions, and neutral particles. It has properties and behaviors that are drastically different from the other three states of matter.
Plasma is unique in the sense that all of its particles have an equal number of positive and negative charges. This balance prevents the plasma from having to obey the same laws of attraction or repulsion as the other states, which helps account for its unique characteristics.
Is plasma the universe’s missing matter?
The concept of “missing matter” is not a new one in the field of astrophysics. Scientists have long postulated that there must be some form of matter that we cannot detect using traditional means, because the observed gravitational effects on galaxies and other large celestial structures are not enough to account for the amount of visible matter present.
One of the most compelling explanations for this so-called missing matter is that it exists in the form of plasma.
Plasma is a state of matter that is similar to gas, but its atoms have been stripped of some or all of their electrons, leaving them in a highly ionized state. Plasma is the most common state of matter in the universe, and it is found in everything from the sun and other stars to the interstellar and intergalactic spaces between them.
Despite its ubiquity, however, plasma is notoriously difficult to detect using traditional means, such as telescopes or other observational tools.
In recent years, however, scientists have been able to use a variety of methods to map the distribution of plasma in the universe. These techniques rely on the fact that plasma emits radio waves and other forms of electromagnetic radiation, which can be detected and analyzed using specialized instruments.
By mapping the density and distribution of plasma throughout the universe, researchers have been able to gain a better understanding of how it interacts with other forms of matter, such as dark matter and visible matter.
One of the main reasons why plasma is a strong contender for the missing matter in the universe is that it has a significant amount of mass. While plasma is primarily composed of charged particles, these particles still have mass and therefore contribute to the overall gravitational effects that we observe in the universe.
Furthermore, plasma is capable of interacting with other forms of matter in ways that we are only just starting to understand. For example, recent studies have suggested that plasma may be responsible for some of the filamentary structures that we observe in the intergalactic medium, which could have implications for our understanding of how galaxies form and evolve.
While it is still too early to say with certainty whether plasma is the universe’s missing matter, the evidence certainly suggests that it is a strong possibility. As we continue to develop new tools and techniques for observing and analyzing plasma in the universe, we will likely gain a better understanding of its properties and its role in shaping the cosmos as we know it.
What is 90% all elements in universe?
The universe is vast and complex, consisting of everything and anything that exists in space, including all matter and energy. According to scientific estimates, the universe is thought to contain approximately 100 billion galaxies, each containing anywhere from tens of millions to trillions of stars.
In terms of the elements that make up the universe, the most abundant element is hydrogen, which makes up about 75% of the universe’s elemental composition. The next most abundant element is helium, which makes up around 24% of the universe’s elemental composition. This means that together, hydrogen and helium collectively make up approximately 99% of the elemental composition of the universe.
However, when we consider the remaining 1% of the universe’s elemental composition, it is important to note that there are still a vast number of diverse elements that exist. These elements include everything from heavy metals like gold and platinum, to lighter elements like carbon and nitrogen, to even rarer elements such as uranium and plutonium.
Therefore, when we talk about 90% of all elements in the universe, we are likely referring to a subset of the most common elements beyond hydrogen and helium. This means that the remaining 1% of the universe’s elemental composition accounts for a considerable amount of elements, and is still incredibly complex and diverse.
The elemental composition of the universe is a fascinating and complex topic, and ongoing research continues to uncover even more about the different elements that make up our vast and beautiful universe.
Is everything 99% empty space?
The statement that everything is 99% empty space is rooted in the science of the structure of matter. According to modern physics, everything in the universe is made up of atoms, which themselves consist of smaller particles like protons, neutrons, and electrons. These particles are held together by forces, giving rise to the solid objects we see and interact with.
However, we can think of atoms as being mostly empty space due to the fact that these particles are incredibly small compared to the size of the atom as a whole.
For example, to put this into context, we can consider a simple analogy of an atom being like a fruit in space. Imagine an orange in the middle of a large, empty football field. Now, imagine that the size of the orange represents the nucleus of the atom, while the electrons are like tiny flies buzzing around the edges of the field.
The vast empty space between the orange nucleus and the electrons is similar to the empty space within an atom, where the majority of the volume is composed of this empty space containing the buzzing electrons.
This means that atoms are almost entirely made up of empty space, with the actual physical matter concentrated in a tiny fraction of the overall volume. In fact, the empty space between atoms in a solid object is also significant. When you walk on a hard floor, for example, you are actually standing on a sea of atoms separated by empty space.
So, if we zoomed in at a high enough level, we could see that everything is mostly empty space.
While this may seem surprising, it is important to note that matter and its properties are still dictated by the particles that make it up, even if they are widely spread out. The real impact of matter being 99% empty space is that exploring the inner workings of atoms and particles has led to many scientific breakthroughs and technologies we use today, such as nuclear power and electronics.
The statement that everything is 99% empty space is indeed based on scientific fact. While we are able to see and touch solid objects in our everyday lives, on a microscopic level, the true structure of matter reveals that most of what we consider “solid” is actually empty space between atoms and their particles.
However, it is important to remember that the properties and behaviors of matter are still very much dependent on the particles that make it up, even if they are largely separated by empty space.
