Dark Matter and Dark Energy

There is perhaps no current problem of greater importance to astrophysics and cosmology than that of "dark matter". The controversy, as the name implies, is centered on the notion that there may exist an enormous amount of matter in the Universe that cannot be detected from the light that it emits. The evidence of dark matter is from the motions of astronomical objects, specifically stellar, galactic, and galaxy cluster/supercluster observations.

With all our knowledge of everything around us, overwhelming as it may be, there are still a lot of aspects that are unknown to even the smartest scientists. Did you know that humans know only 5% of the entire universe? Yes, everything we know about the Earth, the Milky Way, and all the planets is barely even a fourth of what comprises the entirety of the universe. Knowing that, it would be illogical to say that the creatures on Earth are the only forms of life in the universe. Today I will tell you about unidentified object sightings, close

Astronomers believe there is enough dark matter in the universe to slow its expansion gradually toward a stop.

Dark Matter is a very interesting book that I would recommend you to read. The author of Dark Matter has both assimilation and tolerance in the book. In the book tolerance is used by Jason having to survive in different situations. At one point in the book he goes to a world that is covered in snow. He built tolerance to the cold and was able to carry Amanda to a cabin and survive. But also has assimilation sprinkled in. Jason had to adapt to his doppelgangers and their worlds.

The trace of energy was coming from the planet Earth. Orion flew to Earth to find the dark energy.

Simulations of galaxy formation based on the Lambda Cold Dark matter (ΛCDM) cosmological model predict that a large galaxy such as the Milky Way should have many (~ 200) dwarf satellite galaxies. However, only about 20 or 30 have been identified. Where are the rest? Warm dark matter, constituting of sterile neutrinos, is lighter and since dwarf galaxies consisting mainly of dark matter are so difficult to find by visible light, there could be enough of them to reconcile the large number of dwarf galaxies that simulations predict to exist with the small number actually observed. We are looking for a weak unidentified emission line at E = (3.55−3.57) ±0.03 keV in a stacked XMM-Newton spectrum of Dwarf galaxies, which are the satellite galaxies of our Milky Way.

Well think again!” Shagloom’s voice echoed through the empty streets of the town. Just then Shagloom jumped out of a rift beaten and battered. Shagloom started to form an orb of dark matter in his hand, which grew bigger and bigger.

Dark matter is a very mysterious concept and scientist are not sure what it is . Dark matter is a substance that we do not know exactly what it is. Dark matter is something that is matter but is invisible to the best machines.Some of them are x-ray telescopes and dark matter is too cold for the machines to see. Can you believe that you can't see dark matter with our technology?

M-Energy (Magical Energy) is the idea that the energy that a black hole emits millions of years after consuming an object is the “stardust” that humans are made of. Muggles call M-Energy Hawking Radiation; Stephen Hawking theorized that things that pass a black hole’s event horizon, “the point of no return,” do return with lots and lots of time. The accuracy of this claim about whether things can ever escape from a black hole is yet to be proven. But if it is true (and Hawking is literally a genius), the energy expelled from black holes is not what gives certain people the ability to do magic. In other words, M-Energy (Magic Energy) does not exist, although it is unknown if the same can be said for its Muggle name. One might argue that Hawking Radiation and M-Energy are two names for the same thing, so if one does not exist, the other cannot, either. But wizards created a cure for the common cold—the Pepperup Potion—while Muggles have not; why cannot the opposite be true? The events in Wizarding and Muggle

But studying these masses as well as other things in the universe helps us to understand the universe and its fate. Which is why a press release by the National Radio Astronomy Observatory (https://public.nrao.edu/news/pressreleases/brown-dwarf-jets)

Dark Matter and Dark Energy are important. They can help us know how the universe began. These two are the mysteries of the universe; they compose about 90% of the universe. They are mysteries because we believe that they exist but we can’t see them or detect them. People question whether they manifest to be the same thing. Astronomers know very little about their constitution so they cannot assume they are related.

Definition of matter was a big controversy in science. Approximately two and third millennium ago, the Greek philosopher Aristotle (384 BC -322 BC) wrote that matter consist of fire, wind, earth and water and that different compounds are obtained by different combinations of these elements (Laycock, 1979). Around 2000 years after that and through many contributions from many scientists, William Odin categorised the elements based on their atomic number and stated that these elements combine with one another to create different compounds (Scerri, 2007). At present, around 100 elements react with one another to form thousands of known and unknown compounds. However in the last century, it was found that these elements and compounds only represent 4.9% of the universe. The other 95% is dark matter (26.8%) and dark energy (68.3%) (Francis, 2013). This means that scientists spent more than two millennia trying to understand the smallest portion of the universe. Hence, scientists are new to the concept of dark matter and dark energy. So what is dark matter and dark energy that represent the majority of the universe and what are the theories that illustrates their behaviour in the universe, causing dark matter and dark energy be accepted hypothesis to explain the different observation?

A galaxy, also called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all bound to form a massive cloud in which we live in. Although it cannot be very well explained, dark matter makes up at least 90% of a galaxy’s mass.
