Dark Energy Vs Dark Matter

Several hundred thousands years after the Big Bang, the stars began to light up the dark universe. As the universe expanded, it got colder and darker and less like a place that might produce things like heavier chemicals, plants, and animals. This period of the history of the universe was called the Dark Ages. During the Dark Ages, a lot of atoms was flowing through space, which contained 75% hydrogen with one portion and about 25% helium with two protons. Some areas in the universe were just slightly hotter and denser than others, and gravity magnified those differences. As gravity increased, the whole thing was clumping faster. At the center of each of those clouds of atoms, atoms began to bang into each other more violently and heat up particularly

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.

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.

The particles include photinos, neutrinos, gravitinos, axions, and magnetic monopoles, among many others. Of these, researchers have detected only neutrinos -- and whether neutrinos have any mass remains unknown. Experiments are under way to detect other exotic particles. If they exist, and if one has a mass in the correct range, then that particle might pervade the universe and constitute dark matter.

Dark Matter is revealed in many ways and one example of dark matter in action is how it holds our galaxies together. This is known because even though dark matter does not emit or absorb light or electromagnetic radiation, it does exert a gravitational force upon other galaxies, stellar clusters, and many other substances through the universe. One example of how amazing dark matter is is how it exerts a gravitational force upon stellar clusters. Stellar clusters are clusters of individual stars that move at rapid speed that are gravitationally bound. But it has been scientifically proven that the individual stars are moving too fast to be held together by the gravitational attraction of other stars. In this case dark matter provides the extra vigor that is needed.

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

The universe is said to have begun with a cataclysm that generated space and time, as well as all of the matter and energy that the universe will ever hold. For an incomprehensibly tiny fraction of a second, the universe is – theoretically – an infinitely dense fireball. At 10-35 to 10-33 seconds, a runaway process called "inflation" is said to have caused a vast expansion of space filled with energy. The inflationary period is stopped only when this has converted into the matter and energy we know of today.

Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive. When you look at really large masses, like the Earth and Moon, the gravitational pull becomes very impressive. The gravitational force between the Earth and the molecules of gas in the atmosphere is strong enough to hold the atmosphere close to our surface. Smaller planets, that have less mass, may not be able to hold an atmosphere. This can be related to the gravity force lab because you can make the person with either magnet bigger or smaller. When you made both bigger they were harder to pull apart but when you make them both smaller they were easier to pull apart.

This has led to new theories such as modified Newtonian dynamics, a modified law of gravity, which tries to explain the gravitational discrepancies seen in the motions of galaxies [7]. However researchers have made measurements of the influence of gravity in our solar system which fits our current understanding of gravity. Consequently the modified gravity law would have to preserve the observed behaviour of gravity in our solar system as well as explain the gravitational discrepancies and no such solution have been found. So dark matter can be considered the most viable solution to this problem as evidence of its gravitational effects is enough to indicate its

Many people have heard of dark matter, however most will admit that they do not have a clear understanding of its existence. To most, dark matter remains a mystery or just a science fiction term. Dark matter is a matter—simply meaning that it has mass. Many people find it hard to comprehend the term dark matter because it cannot be seen. It is not visible because it does not interact with light (meaning it does not give off light or absorb light). Therefore, if we cannot see it, how can we believe that it exist. Experiments and observations have been conducted to build evidence that dark matter exists. The information and explanations gathered present convincing evidence for dark matter. This evidence is found within the speed of galaxy

Essentially, it is the undetectable matter that influences the gravity of galaxies and the way we perceive light from distant galaxies. This gravitational effect is the only way we know that dark matter is there. This is because without a considerable amount of matter in addition to the regular matter in the universe, large galaxies would not be able to the forces of gravity and makes up more of the universe than dark matter and regular matter combined (about 68% of the universe)

one big scientific discovery of the 20th century was of the equation e=mc2 which states thaat energy has mass. the m is mass or matter and c is the speed of light. nuclear reactors convert only a small fraction of the total mass of their fule to energy however if we were able to convert all mass to energy the output would be huge. the energy in all matter is encomprehensibly vast. there has to have been intellegance behind creation.

Dark matter makes up about 27 percent of our entire universe (Dark Energy, Dark Matter - NASA Science), and another 75 percent of all matter (Dunbar). Dark matter forms in giant, unevenly spread clumps around celestial bodies, mostly galaxies. One theory of how the clusters of dark matter form is the Weakly Interacting Massive

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.

Dark Matter is an unidenti ed form of matter that is present in our universe along with visible (baryonic) matter, radiation and dark energy. It makes up around 26.8% of the whole universe (from
