Hello everyone. Dark matter is a type of matter that is thought
to exist in the universe but cannot be directly observed. Astronomers estimate that only about 5 percent
of the total amount of matter in the universe is visible matter. The remaining 95 percent consists of mysterious
components called dark matter and dark energy. Dark matter, as its name suggests, does not
reflect, absorb or emit light, so it cannot be observed directly. However, the existence of this type of matter
has been indire
ctly determined by phenomena such as observed galaxy motions, cosmic microwave
background radiation, and the formation of large-scale structures .
The rotation rates of galaxies are higher than predicted based on the visible matter
they contain. This suggests that there is an extra gravitational
effect holding the galaxies together. Dark matter is one candidate thought to be
responsible for this extra gravitational effect. Dark matter can exist in two different forms:
cold dark matter, which is
thought to consist of fundamental particles, and fast-moving
hot dark matter. It is not known exactly what it is, but scientists
are conducting experiments and analyzing observational data to investigate dark matter. Dark matter has a major impact on the formation
and structuring of the universe. Many observable phenomena , such as galaxy
formation and evolution, the formation of cosmic structures such as cosmic filaments
and large voids, the movement of galaxy clusters and the interaction of bl
ack holes , point
to the existence of dark matter. However, dark matter is an area that still
contains many unknowns. Scientists continue to work to learn more
about the nature, interactions and formation of dark matter particles. It is important to study the discovery of
dark matter. phenomenon that appears to explain the movements
and structures observed in the universe . Dark matter cannot be observed directly because
it is invisible and therefore it is a very difficult subject to discover. H
owever, some observations and calculations
reveal the existence of this mysterious substance. Dark matter was first noticed in the early
20th century when a problem arose in explaining the rotation rates of galaxies. While the stars in galaxies moved more slowly
towards the outer parts during their rotation, the observed rotation speeds were not sufficient
to explain this situation. This showed that an invisible substance was
needed in the outer regions of galaxies. fritz Zwicky is a scientist w
ho played an
important role in the discovery and understanding of dark matter. Zwicky is a Swiss-American astronomer and
astrophysicist. He proposed the theory of dark matter by studying
the motions of galaxies in the 1930s. Coma Cluster , Zwicky noticed an inconsistency
in the motions of the galaxies. Based on the rotation rates of the galaxies,
he observed that the total mass in this cluster was too high to be explained by visible matter
alone. As a result, he posed the "extra-mass problem"
an
d suggested that an invisible substance was needed in galaxies. Zwicky became one of the first scientists
to introduce the concept of dark matter. Proposing the theory of dark matter, he stated
that an invisible substance was needed to explain the anomalies in the rotation speeds
of galaxies. Additionally, this discovery contributed to
an important understanding of the structure of galaxy clusters and the formation of the
universe. fritz Zwicky's work on dark matter has become
one of the corners
tones of modern cosmology. His discoveries and predictions have been
supported by further research into the existence of dark matter and the important role it plays
in the universe. Zwicky's work attracted the attention of the
scientific community on dark matter and increased the momentum of dark matter research. Further evidence of dark matter emerged in
the 1970s with observations of galaxy clusters and the rotation curves of galaxies. British astronomer Vera By measuring the rotation
rates of
galaxies, Rubin and his colleagues discovered that the outer regions of galaxy
disks also rotate faster than expected. These observations showed that there is more
mass in addition to the visible matter at the center of galaxies, and that the source
of this mass may be dark matter. Albert Bosma : Vera in the 1970s He is a researcher
who supports Rubin's work. By examining the rotation curves of galaxies,
he showed that the outer regions of galaxies also rotate faster than expected. Known for hi
s work on the cosmic microwave
background radiation, James Peebles made important discoveries about the structure and composition
of the universe. He developed cosmological models that predicted
the existence of dark matter and emphasized the role of dark matter in the formation of
the large-scale structures of the universe. George Smoot and John Mather are two notable
astrophysicists known for their discovery of the cosmic microwave background radiation. In 1992, a research team led by Smoot an
d
Mather was sent into space to measure the cosmic microwave background radiation using
a satellite called COBE. The cosmic microwave background is radiation
that formed in the early universe, approximately 380,000 years after the Big Bang . This radiation
allows us to have important information about the evolution of the universe. By precisely measuring the distribution of
the cosmic microwave background radiation and temperature fluctuations, Smoot and Mather's
work became a major discovery ab
out the formation and structure of the universe. This discovery made significant contributions
to confirming the Big Bang theory and deepening our understanding of cosmology. George Smoot and John C. Mather won the Nobel
Prize in Physics for this work in 2006. This award was given to them for the discovery
of the cosmic microwave background radiation and their contributions to cosmology. Smoot and Mather's work contributed to our
development of an in-depth understanding of the origin and structu
re of the universe and
was an important milestone in the field of cosmology. Many experiments and observations have been
carried out to determine the nature and composition of dark matter. Large Hadron High-energy particle accelerators
such as the Collider have conducted experiments aimed at discovering dark matter particles. Additionally, observations have been made
examining the large-scale structures of the universe, such as galaxy clusters, galaxy
collisions, and cosmic microwave background
radiation, to study the gravitational effects
of dark matter. Observations have shown that dark matter is
widespread in the universe and plays an important role in the formation of large-scale structures
of the universe. While only about 5 percent of the total amount
of matter in the universe is visible matter, the remaining 27 percent consists of dark
matter and the remaining 68 percent consists of another mysterious component called dark
energy. Observations and Findings of Dark Matter
Since d
ark matter is a substance that cannot be observed directly, its findings are obtained
indirectly. The rotation rates of galaxies are higher
than expected based on the visible matter they contain. This indicates that there is an additional
source of gravity around the galaxies. Dark matter is a possible candidate for this
additional source of gravity. Observations of galaxy velocity distributions
are one of the evidences for the existence of dark matter. galaxies is important evidence showing the
existence and influence of dark matter. Stars and gas, which belong to normal matter,
generally concentrate towards the center of a galaxy, while dark matter is distributed
around the island. This affects the velocity distribution of
the galaxies. The velocity distribution of galaxies shows
how the velocities of stars and gases on the island are distributed. The gravitational effect of normal matter
accelerates the stars towards the center of the island, while the stars around the island
have s
lower velocities. However, observations have shown that the
velocity distributions of stars and gas in galaxies differ from what was expected. The reason why the velocity distributions
of stars and gas in galaxies differ from expected is the effect of dark matter. Dark matter is found in large regions around
galaxies and attracts stars and gas with its gravitational pull. This gravitational effect causes the stars
and gas around the island to have higher velocities. Observations have revealed th
at the velocity
distributions in galaxies vary in a characteristic way, indicating the presence and distribution
of dark matter. In particular, the observed velocity distributions
were consistent with models used to predict the presence and amount of dark matter. Large-scale structures in the universe are
driven by and contribute to their formation by dark matter. Structures such as galaxy clusters, superclusters,
cosmic filaments and voids are formed by the gravitational influence of dark matte
r. These structures are identified by observations
and support the existence of dark matter. Cosmic microwave background radiation from
the early universe provides information about the general structure of the universe. Detailed maps show that the distribution of
matter in the universe is uneven and the presence of dark matter. These observations reveal that dark matter
shapes the large-scale structure of the universe. gravity Lensing is an observation technique
used to confirm the existence an
d distribution of dark matter. Galaxies or clusters of galaxies with large
masses can bend light, distorting distant sources behind them. This distortion is an important observational
tool in determining the existence and distribution of dark matter. gravitational Lensing is an important tool
for determining the presence and distribution of dark matter. The gravitational effect of dark matter can
bend the path of light and distort the image of a distant source. gravitational to this event It is
called lensing
. gravitational Lensing is a method used to
detect the presence of dark matter and map its distribution. When a light source passes through a region
with a high concentration of dark matter, the path of the light is bent by the gravitational
effect of the dark matter and the source appears distorted. These distorted images can be used to determine
the presence and distribution of dark matter. Because gravitational Lensing provides information
about the density profile and distribu
tion of dark matter, depending on the shape and
degree of distortion caused by the effect of dark matter .
Observations and analysis, gravitational showed that the number and properties of lensing
events confirm the existence of dark matter. In particular, the gravitational effects seen
around galaxy clusters, which are large-scale structures, Lensing events indicate that dark
matter is concentrated in regions where its density is high. gravitational Lensing events can be combined
with many obse
rvational methods used to map the distribution of dark matter and confirm
dark matter models. For example, gravitational effects combined
with anisotropies of the cosmic microwave background radiation By analyzing lensing
events, more detailed information about the distribution of dark matter and the structure
of the universe can be obtained. In this way, gravitational Lensing allows
us to gain a greater understanding of the existence and influence of dark matter. Future observation projects and
technological
developments will It will enable a more detailed examination of lensing events and a better
understanding of the nature of dark matter. Scientists use computer simulations and cosmological
models to understand dark matter. These simulations mimic dark matter distribution
and evolution, which is consistent with observations. Simulations allow us to understand the influence
of dark matter on the formation of structures in the universe and confirm theoretical predictions. Dark matter
has significant effects on galaxy
formation and growth. It creates regions of high density and allows
normal matter to come together under the influence of gravity. It triggers the accumulation of normal matter
in these dense regions, and this accumulation initiates galaxy formation. The gravitational effect of dark matter can
shape the different structures of galaxies, such as disks, centers and clusters. It also plays an important role in explaining
the rotation rates of galaxies. Observation
s show that the rotation speeds
of galaxies are higher than expected based on the visible matter they contain. These velocities are explained by the additional
gravitational effect of dark matter. Dark matter contributes to the growth of galaxies
by ensuring their rapid rotation. Additionally, it plays a critical role in
the formation and growth of galaxy clusters. Galaxy clusters are defined as structures
containing large amounts of galaxies. The gravitational effect of dark matter enables
the
formation of galaxy clusters and the growth of these clusters. Galaxy clusters are the regions where the
concentration of dark matter is most evident. Large-scale structures in the universe are
formed by the presence and influence of dark matter. Cosmic filaments are known as long fiber-like
structures that connect galaxy clusters and where the concentration of dark matter is
most prominent. The gravitational effect of dark matter supports
the formation of these filaments . Large voids are areas
where dark matter is less abundant. The gravitational influence of dark matter
affects the evolution and growth of galaxies. Galaxies can accumulate more matter and grow
in regions where dark matter is concentrated. The gravitational effect of dark matter ensures
that galaxies stay together and maintain their structure. Dark matter has indirect effects on hot gas
and star formation. The pull of dark matter promotes the condensation
of gas and the collapse of clouds of hot gas. This collapse pro
cess initiates star formation. Thus, dark matter has a decisive influence
on the formation of stars and the development of galactic disks. Dark matter and dark energy are two important
components that play a decisive role in the expansion of the universe. The expansion of the universe is generally
based on the big bang theory, and this expansion process is affected by dark matter and dark
energy. Dark matter has a different structure than
the normal matter found in the universe and therefore can
not be observed directly. However, dark matter is a component that interacts
through the gravitational force. The gravitational effect causes dark matter
particles to come together and form regions of density. These density regions also trigger normal
matter to come together and support the formation of galaxies. Dark matter holds galaxies together under
the influence of gravity and contributes to the formation of galaxy clusters . This creates
a resistance to the expansion of the universe. In o
ther words, dark matter has the effect
of slowing down the expansion of the universe. However, the most dominant influence on the
expansion of the universe is provided by dark energy. Dark energy is a component that accelerates
the large-scale expansion of the universe. Dark energy is a mysterious form of energy
that is distributed homogeneously throughout the universe. This energy accelerates the expansion of the
universe by increasing the rate at which it is receding. Dark matter and dark ener
gy together have
a decisive influence on the expansion of the universe. Dark matter slows down the expansion of the
universe, while dark energy accelerates the expansion of the universe. These two components allow us to understand
the dynamics of the expansion of the universe and are an important source of information
about the evolution of the universe. Dark matter is a substance commonly found
in the universe, but cannot be directly observed because it does not interact with electromagnetic
ra
diation. In contrast, we observe that dark matter has
significant effects on normal matter and light through its gravitational effect. Various theories and hypotheses have been
proposed regarding the content and composition of dark matter. According to the Cold Dark Matter theory,
dark matter consists of cold and slow-moving particles. One of the most common theoretical candidates
are particles known as weakly interacting gravitational particles. These particles may have different properties
tha
n the particles described in the standard model and may be resistant to electrical or
nuclear interactions. Hot Dark Matter theory is another important
topic. These substances consist of fast moving and
low mass particles. These particles, like neutrinos , are candidates
for hot dark matter. However, neutrinos are not thought to be sufficient
to fully explain dark matter. According to the Extreme Cold Matter theory,
dark matter particles consist of particles at very low temperatures and moving e
xtremely
slowly. It is not yet known exactly what these particles
are and what interactions they have. The Accidental Matter theory is a theory put
forward on the composition of dark matter. According to this theory, interactions can
occur between dark matter particles. These interactions can affect the behavior
and distribution of dark matter. This theory could help explain observed phenomena
of dark matter. To obtain more precise information about the
composition of dark matter, scientists con
duct research using laboratory experiments and
observational data. Important experiments and observation projects
can help us understand the nature and composition of dark matter. The way dark matter interacts is also not
fully known. Since it is closed to electromagnetic interaction,
it is thought to be a component that does not interact with light and does not leave
a trace in the electromagnetic spectrum. However, it is observed that it has effects
on normal matter and light due to the effect
of gravity . It is thought that dark matter
promotes the formation of galaxies, enabling normal matter to come together and affecting
galaxy movements. The nature of dark matter and the ways it
interacts are still active research topics. Scientists are trying to detect dark matter
particles in high-energy experiments such as the large hadron collider. Dark matter and dark energy are two different
components that have different roles and effects in the universe. Although it is difficult to say t
hat there
is a direct relationship between the two, they are interconnected in understanding the
expansion and structure of the universe. Dark matter is a component of normal matter
found in the universe that interacts with gravitational effects and does not interact
with observable light. Dark matter ensures the formation and cohesion
of galaxies, is effective in the formation of large-scale structures spread throughout
the universe, and has a slowing effect on the expansion of the universe. On
the other hand, dark energy is a form of
energy that accelerates the expansion of the universe. Dark energy is distributed homogeneously throughout
the universe and has a positive energy density. Therefore, dark energy acts as a driving force
against the expansion of the universe and increases the rate of expansion. Dark matter and dark energy are generally
considered together, although they have different effects on the expansion and structural formation
of the universe. Due to its effects on
the expansion of the
universe, dark energy determines the large-scale structure of the universe, while dark matter
enables the formation and cohesion of galaxies. However, the relationship and interaction
between dark matter and dark energy are still not fully understood. Scientists are conducting further research
into the nature of these two components and their effects on the expansion of the universe. These studies aim to provide more information
to help us understand the structure, formation
and expansion of the universe and to solve
the mystery of dark matter and dark energy. The nature and properties of dark matter remain
largely a mystery. However, future new discoveries and developing
research methods are promising for understanding dark matter and elucidating its nature. The sensitivity of detectors used in direct
detection experiments and data analysis methods are constantly being improved. Thanks to more sensitive detectors and advanced
data analysis techniques, there may be
a better chance of directly detecting dark matter particles. Next generation experiments aim to examine
the nature and interaction properties of dark matter in more detail. Observational data are an important resource
for understanding the effects of dark matter in the universe. Advancing technologies and telescopes will
allow us to observe the motions of galaxies, the distribution of galaxy clusters, and the
cosmic microwave background radiation more precisely. This could help us study the dis
tribution
and effects of dark matter in more detail. Scientists are investigating the nature of
dark matter and its effects on the expansion and structural formation of the universe through
simulations and theoretical models. More realistic simulations can be achieved
thanks to developing calculation methods and supercomputers .
Big data analysis and artificial intelligence methods play an important role in dark matter
research. Future research will leverage these techniques
to more effectively
analyze more complex data sets. Artificial intelligence algorithms can be used to identify signatures of dark matter,
map its effects, and detect dark matter particles. It is important to combine various observation
methods to better understand the nature and effects of dark matter. For example, cosmic microwave background radiation,
galaxy motions and gravitational More comprehensive information about the distribution and effects
of dark matter can be obtained by combining different observation
techniques such as lensing
. In addition to existing theories about the
nature of dark matter, it is also important to develop new theoretical approaches. These approaches may focus on alternative
models and hypotheses to explain the properties of dark matter. New theoretical approaches may help us understand
the nature of dark matter and confirm its existence. Future space missions may offer new ways to
observe and understand dark matter. Telescopes and sensors with more advanced
technologies
in space may allow us to collect more data about dark matter. Scientists conduct studies in underground
experimental facilities to discover possible particle components of dark matter. Future experiments may increase the chances
of directly detecting or interacting with dark matter particles. Future telescopes and observatories may be
capable of observing dark matter more precisely. These observations can provide more detailed
information about the distribution, motion and interactions of dark m
atter. These potential advances could offer the chance
to expand our knowledge of dark matter and take a significant step toward better understanding
the role of this mysterious substance in the universe. Don't forget to subscribe for brand new documentaries
