Basic Understanding Of Dark Matter

Dark matter and dark energy are two entities that have very little known about them, except that they make up about 95 percent of the universe. Even though this is a large part of the universe, it wasn’t even thought about until the 1960’s or the 1970’s. This is because of the fact that it is very hard to detect and almost impossible to see. Although it is impossible to see, we can see the effects of them both in our galaxy.

The visible universe- including Earth, the sun, other stars, and galaxies is made of protons, neutrons, and electrons bundled together into atoms (National Geographic, 2012). Astronomers use the term ‘baryonic’ to refer to all objects made of normal atomic matter, essentially ignoring the presence of electrons (Swinburne University, 2015). Baryons interact with each other through gravity, nuclear forces and the electrostatic force. These interactions are what allow baryonic matter (such as stars) to emit light (Grocutt, 2012). One of the most surprising discoveries of the 20th century was this ordinary, or baryonic, matter makes up less than 5 percent of mass of the universe. The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent) (National Geographic, 2012).

Little is known about the mysterious force called dark matter and dark energy. The information that is known about dark energy, is that it is causing a more accelerated expansion of the universe. This is why dark energy is so fascinating, because it makes up seventy five percent of the universe, yet we don't even know that much about it.

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

To discover what the universe is made of and how it works is the challenge of particle

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

The author of Dark Matter, Blake Crouch, develops the idea of assimilation throughout the book because as Jason Dessen is having to go through all the different multiverses, he is having to adapt to what is happening in that particular world at that particular time. Jason is constantly going into different versions of Chicago trying to return back to his original world, but there are many obstacles that he has to overcome in order to do that. If Jason was not able to adjust to the changes he was experiencing, he could not survive all of the worlds the box was taking him to. Jason is first faced with the tragedies of the box when he is kidnapped by a guy in a geisha mask. This guy forces him to drive to a destination, where he then wakes up next to a metal box, oblivious to what had just happened the previous night.

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.

Unimaginable numbers of earth-like planets, beacons on the outer edge of our solar system, a constant presence in space; these ideas seem as if they have been taken straight

Suggested in his 100 advice for a human, “87. Dark matter is needed to hold galaxies together. Your mind is a Galaxy. More dark than light. But the light makes it worthwhile.”

Since the dawn of civilization, humans have always wondered if they are alone in this extensive collection of galaxies called the Universe. Perhaps, they are not alone. Is there intelligent life among the cosmos? The Milky Way galaxy is just one of nearly a hundred billion galaxies. With such a vast number of galaxies that are billions of light years away, the idea of contacting another form of intelligent life seems impossible. After the invention of the radio in the early 20th century, researchers began to detect unexplained signals.

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.

In the grand scheme of things, the Milky Way galaxy is just a microscopic portion of one single galaxy in the universe. The Sun that the Earth rotates around is one out of hundreds of billions of stars in out galaxy alone, and more than that our galaxy is but one of around 50 billion to 1 trillion galaxies, and that is just in the known universe. Nearby stars are separated from the Earth by light years, and relatively close by galaxies are so much father away even than that, with the most distant galaxies from our planet being almost 14 billion light years away. As time has passed, we as a species have learned so much about our own galaxy and those that stretch beyond us into the unknown universe. The following paragraphs will go in depth
