Money matters

During the Early Middle Ages, a common practice of feudalism began. Knights formed a relationship with a local king in order to receive protection, fief, and justice. In return, knights had the duty to stay true and serve their lord unconditionally, whether on the battlefield, in a council, or wherever the king goes. Likewise, the knights under a lord were called to fight alongside one another unto death. If death grasped ahold of one of their fellow companions, the vassals were called to avenge

Ways To Use Landscaping Rocks In Your Yard Rocks are attractive landscaping elements. They come in a variety of shapes and colors, so they add nice visual appeal. Plus, they're natural and may be more appealing to you than shredded rubber or dyed bark. Rocks also last for a long time because they don't decay like wood does. Here are some of the ways you can use landscaping rocks. Mulch For Plants And Flowers You may think if shredded wood, leaves, or straw as forms of mulch, but rocks make good

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

Despite its invisible interior, the presence of a black hole can be inferred through its intersection with other matter and with electronic radiation such as visible light. Matter that falls into a black hole can form an external accretion disk heated by friction, forming some of the brightest objects in the universe. If there are other stars orbiting a black hole, their orbits can be used to determine

astronomers first discovered them. The astronaut said “he saw a blob of black matter and black holes are made when a star burns out or explodes but the astronaut never truly saw the actual thing. Black holes absorb light particles that are close enough to it so that it can thrive and continue. When a black hole goes away the light that it absorbed is turned into a new star. When an astronomer found a black sphere shaped cloud of matter in space he didn't really see it but he saw it pulling in large amounts

either a  solid or a liquid- or perhaps even both? To begin with, discussing the essential knowledge of solids, liquids and even gases, clarifies any unknown concepts of these three states. Solids, Liquids, and Gases… What Are They? First of all, matter (mass, or anything that takes up space) stays in three state, which is solid, liquid, and gas; the fourth state is plasma (however this notion is more complex, and shall be learned later). Water follows the same theory as well.  A solid is considered

“Dark energy comprises 69% of the universe, dark matter makes up 25%, and ordinary atomic matter only makes up 5%,” (Spergel). For centuries, scientists have been gathering innumerable amounts of information to comprehend the elaborate universe. A handful of these observers have detected invisible forces comprising space. Countless amounts of astronomers have tried to explain this dark mystery. In 1917, Albert Einstein was able to add the cosmological constant to his general theory of relativity

Dark Matter: The Number One Mystery in Our Universe Dark matter is a mystery in astrophysics that could not be explained until the 1970s. Even now, with the understanding of space we have, cosmologists do not know a plethora of knowledge about dark matter. Dark matter is non-baryonic matter that cannot be detected in normal ways and was not discovered until the 1930s, but is one of the main components of our universe. Dark matter makes up about 27 percent of our entire universe (Dark Energy, Dark

The sixty-symbols website has quite the collection of intriguing astronomical theories and interviews, but I specifically chose that of the black hole that contains interviews by Omar Almaini, Ed Copeland, Tony Padilla, Meghan Gray and Mike Merrifield from the University of Nottingham. The video began by a man revealing to his audience that he is often questioned about his personal opinion on black holes, which he informs us that “of course” he sees them as frightening and intimidating but goes on

Here I was, going to Chabot Space & Science Center judging the place would be basically empty on the raining day, but once I rushed inside I heard childrens laughing, I saw all the people crowding around, and oddly, the smell of the delicious fragrant of food. At that point my perspective on the observation just got brighter. Since this was the first time I had been at Chabot or any science centers, I was astonished by the sheer number of people, especially kids walking around at Chabot. When I went
