Though, astrophysicists say that this dark energy differs from anything in space, there are possible solutions to explain the existence of this energy; as well as dark matter. As stated above, astrophysicists know more of what dark matter is not than what it is. Many solutions to this mystery have been proposed, yet nothing is coming into comparison with this anomaly. Researchers find that dark matter is not sharing similarities with stars or planets, leaving physicists open to possibilities. These propositions are said to be black holes, antimatter and baryonic matter.
The Large Hadron Collider helps allow scientists see dark matter particles. The dark matter particles could disappear but they would leave energy and momentum that can be detected. Scientists use the amount of energy and momentum missing to infer that dark matter exists. The Large Hadron Collider can also determine the masses and cross-sections of dark matter.

The first on is “A) a planet is a celestial body that is in orbit around the sun B) has sufficient mass for its self-gravity to overcome rigid body forces so that is assumes a hydrostatic equilibrium (nearly round) shape and C)has cleared the neighbourhood around its orbit.” This definition helped determine what a planet is and is not, and also helps show that Pluto is not a planet. It seemed necessary for the IAU to create this list so that it was clear to the astronomers which objects in space and in the solar system could be classified as planets.

People question whether they manifest to be the same thing. Astronomers know very little about their constitution so they cannot assume they are related. Dark Energy is a mysterious force that drives the expansion of the universe. Astronomers states that the universe is expanding and the expansion is accelerating, so the unknown anti-gravity force at work is termed dark energy. Dark energy has important consequences for the evolution of the Universe and the structure within it.
Scientists know how black holes are made, how they affect objects around them, and how to spot them in space. Firstly, there are different types of black holes: Astrophysical, Supermassive, Mathematical, and Physical. A Physical, or regular, black hole is then categorized by its three properties: mass, spin, and magnetic field. A black hole with no spin and no magnetic field is a Schwarzchild black hole. A black hole with spin but no magnetic field is a Reissner-Nordstrøm.
Properties Black holes have many interesting properties. The most obvious from their name is the fact that they can't be seen since no light is emitted from them. One of the ways they can be detected is by the x-rays given off by the matter being pulled into them before it crosses the Schwarzschild radius. As the matter is pulled in, it gains kinetic energy, heats up, ionizes, and when it reaches a few million Kelvin, emits x-rays3. Black holes can also be detected by the way nearby objects are affected by their immense gravity.
IT is tempting to think of the universe before the Big Bang as being a vast, infinite, expanse of empty space, like the space between the galaxy clusters today. The Big Bang, then, would have flung matter into this nothingness, but this is not what happened. Space itself was created during the Big Bang. Einstein and all subsequent cosmologists have viewed space as being as real as matter. In fact, physicists now view empty space as a sea of “virtual particles”.
Even though this is the way in which most branches of science were pushed to the limits of rational thought and into the realm of science fiction, the argument between scientists is whether or not black holes exist. Once it is proven that black holes exist, scientists will argue about whether or not heavenly bodies, or matter such as a spaceship, can orbit a black hole and still return with data. Finally, once it has been proven that black holes can safely be orbited, they will want to know what lies just beyond the photon sphere. New technology will have to be developed in order for scientists to truly know what happens inside of one of these dark beauties. As of right now, there is no way to retrieve data once a spaceship has moved past the photon sphere because data moving at the speed of light would not be able to reach the scientists.
Currently, evidence astronomers have collected that supports the existence of dark matter and dark energy is highly controversial. Even though dark matter and dark energy presently can not be detected by sight, touch, or sound, many astronomers declare that they exist because of the evidence from the gravitational force dark matter exerts upon the galaxies in our universe, the fact that the universe is expanding at a rapid rate, and how dark matter and dark energy confirm the properties of space. Yet, some astronomers disagree with the existence of dark matter and think that MOND is a perfect replacement for dark matter. Other astronomers believe that dark matter is really antimatter, and some scientists think that dark matter could be baryonic matter. Many astronomers who are against the existence of dark energy think that the big bang is responsible for the expansion of the universe.
“Why is the night sky dark?” For thousands of years this question has been asked. Astronomers are continually growing closer to the answer but still no one has yet found an answer that is efficient enough. While scientists steadily collect data, they are hoping to find some clue as to realize that the answer may be because of something that is too mind blowing for us to comprehend. There is perhaps no current problem of greater importance to astrophysics and cosmology than that of "dark matter". The controversy is centered on the conception that there may exist an enormous amount of matter in the universe that cannot be detected from the light that it emits.
