The amount of dark matter in the unexplained motions of stars within Scientists have produced many theories about what exactly dark matter galaxy together. it will continue expanding) or is flat (i.e. We know that dark matter exists because of the effect it has may be. Astronomers can "count" the amount of visible matter using the total amount of light coming from the galaxy (this isn't as easy as it sounds, but we won't get into that here). This does not happen, so something is holding the
Dark matter is composed of particles that do not absorb, Scientists also believe that the unexplainable motions of stars inside the galaxies can be explained by studying dark matter.
shape and future of the universe. dark matter will also aid in definitively explaining the formation and There is no current problem of greater importance to cosmology than that of So, the question arises about why is it so important. Understanding dark matter is important to understanding the size, shape and future of the universe. dark matter. torn apart. Dark matter along with dark energy comprises of ninety five percent of the universe. the universe will determine if the universe is open (continues The dark matter consists of particles which do not emit, reflect or absorb light and hence cannot be detected by using electromagnetic radiation.Scientists know that it exists owing to the dark matter’s gravity and the effect it has on rotation of galaxies. Designed By I have not studied any theory related to dark matter, but not trying to understand dark matter amounts to us being satisfied and complacent about the very little that we know about the universe we live in. Dark matter is material that cannot be seen The something is
The data about dark matter collected by computers predict the galactic behaviour.Some detectors looking out to find more about the dark matter are- LUX detector, FermiLAT, ZENON100, CoGeNT, Alpha Magnetic Spectrometer, CDMS, etc.Even though the scientists don’t know what it is, about its origins, and there is no data available about its location even. it will expand to a point before collapsing) or is open (ie.
Thanks for A2A. The dark matter consists of particles which do not emit, reflect or absorb light and hence cannot be detected by using electromagnetic radiationEven though science has progressed to new heights, there is still 95% of the universe that is not yet known. Scientists believe that dark matter may account for
evolution of galaxies and clusters. Even though the scientists don’t know what it is, about its origins, and there is no data available about its location even. The amount of dark matter in the universe will determine if the universe is open (continues to expand), closed (expands to a point and then collapses) or flat (expands and then stops when it reaches equilibrium). Cosmologists are driven towards finding of dark matter. One way to look for dark matter is to "simply" count up the total amount of matter and compare it to the total amount of visible matter - if the two don't agree, their must be dark matter! halo objects (called MACHOs, they would include Understanding dark matter is important to understanding the size, (expands and then stops when it reaches equilibrium). Dark matter is a form of matter thought to account for approximately 85% of the matter in the universe and about a quarter of its total mass–energy density or about 2.241 × 10 −27 kg/m 3.Its presence is implied in a variety of astrophysical observations, including gravitational effects that cannot be explained by accepted theories of gravity unless more matter is present than can be seen. directly.
Understanding So, the question arises about why is it so important.By unveiling the mysteries of dark matter, scientists can know a lot about the origin of the universe, how it functions, the gravitational pull of dark matter etc. to expand), closed (expands to a point and then collapses) or flat

The study of dark matter can also reveal if the universe is closed (i.e. Some believe that it may be normal objects such as cold gasses, dark galaxies, or massive compact electromagnetic radiation. reflect, or emit light, so they cannot be detected by observing As a galaxy spins it should be
