Dark Matter Essay

own to Einstein's field equations. The universes described by the different scientists varied. De Sitter's model had no matter in it. This model is actually not considered to be a bad approximation since the average density of the universe is extremely low. Lemaître's universe expanded from a "primeval atom." Friedmann's universe also expanded from a very dense clump of matter, but did not involve the cosmological constant. These models helped explain what happened to the universe shortly after its

demise of current life forms, forever changing our world. This is the effect of dark flow. Fortunately this appears to be occurring in distant galaxies, however observations have concluding our galaxy is too being pulled away in a specific direction. This highlights the essentiality of more research being conducted upon this unexplained force. Good Morning class, today my chosen topic is the term dark flow. Now dark flow is a basically a term used to explain astronomical observations,

Modern astronomical research often involves a substantial amount of work in the realms of theoretical and observational physics. Some areas of study for astrophysicists include their attempts to determine: the properties of dark matter, dark energy, and black holes, whether or not time travel is possible, if wormholes can form, or the multiverse exists, and also the origin and ultimate

Descriptions of the 8 planets including a dwarf planet: Mercury: Mercury is only slightly larger than earth’s moon and the sun is the closest to this planet than any other planet. This planet can reach 840 degrees Fahrenheit (450 Celsius). Its diameter is 3,031 miles (4,878 km), its orbit is 88 earth days and mercury’s full day lasts 58.6 earth days. Venus: Venus takes first place when it comes to the hottest planet. Venus is substantially hot with an atmosphere that is toxic. The diameter is

This difference can be explained due to the fact that some of the Data collected for the graph

The Big Bang Theory What exactly is the Big Bang Theory? I know before starting this essay I knew very little of what it consisted. I figured that the Big Bang Theory had something to with the era of a new generation. One in which started after the extinction of dinosaurs to be quite honest. As I learn more about astronomy, this topic struck an interest and technically the big bang theory isn’t something that occurred but rather something that happened. It started the beginning of what we now call

in a larger ring. (Richmond, 2015) Our universe is 85% dark matter, dark matter may be invisible but it still has mass and therefore when light travels towards it, it will bend around them matter causing gravitational lensing. All objects can bend light but usually the change is not measurable on smaller objects such as humans, for any substantial bend to occur it would take a huge mass and a light ray to travel extremely close to the matter. When the light bends it can alters the shape of the image

and a long-tailed companion, located almost 465 million light-years away within the constellation Ursa Major. The pair extends across 80 thousand light-years. The collision between the two parent galaxies produced a shockwave effect that first drew matter into the center and then caused it to propagate outwards in a ring. The elongated companion perpendicular to the ring suggests that Arp 148 offers a unique view of a collision in progress. What probably has been the core of the “target” galaxy can

begins with a cataclysm that generates space and time, as well as all the matter and energy the universe will ever hold. For an incomprehensibly small fraction of a second, the universe is an infinitely dense, hot fireball. At 10-35 to 10-33 seconds a runaway process called "Inflation" causes a vast expansion of space filled with this energy. The inflationary period is stopped only when this energy is transformed into matter and energy as we know it. After inflation, one millionth of a second after
