There is much more dark matter than normal (visible) matter in the universe. According to (this source) roughly 68% of the universe is dark energy. Dark matter makes up about 27%‚ while everything else in the universe (physical matter like the atoms that make up planets and stars) makes up less than 5% of the universe. According to (this source) the universe is actually 96% of dark matter and dark energy. With 73% being dark energy and 23% being dark matter but the implications of this much

Second Chances Carl Band once said‚ “Though no one can go back and make a brand new start‚ anyone can start from now and make a brand new ending.” Growing up‚ I’ve learned to believe in second chances. Throughout my lifetime‚ I have noticed that every person makes mistakes at various points in their lifetime. As humans‚ we tend to hold grudges‚ but what we really need to try is to forgive and forget. Giving people second chances is a great thing to do; but what you do with your second chance is your

Analysis Questions: Cycles of Matter 1. Explain the role of decomposing bacteria in the carbon and nitrogen cycles. In the carbon cycle‚ decomposing bacteria release carbon from the decaying bodies or waste into the atmosphere. Without them‚ it won’t be able for any organism to access the carbon stored in dead bodies. In the nitrogen cycle‚ decomposing bacteria breaks down animal waste‚ which creates ammonia and nitrate products rich in nitrogen. Although no animals or plants cannot directly

Dark Matter Astronomy Samuel Research Topic Topic: Dark Matter‚ Astronomy Saul Perl mutter‚ 2011 states “The Universe in made mostly of dark matter and dark energy‚ and we don’t know what either of them is.” The above statement by Saul Perl mutter suggests that astronomers at this age have found this unknown substance by the name of Dark Matter. We chose this topic on Dark Matter as it intrigues us what is beyond our atmosphere and what is it made off. We want to know how Scientists realized

One fine day‚ as I was going through the library shelf‚ I noticed a book named “the Steve Jobs way” saying iLeadership for a new generation. As I started imagining about leadership‚ I came across a most important thing called positive change. To me‚ positive change means transition and improvement in one’s own thoughts‚ ideas‚ acts and applying those in everyday life to bring the society together for a known cause. When the society gets together‚ working towards one direction‚ a certain positive

States of matter Four fundamental states: Solid - In a solid the particles (ions‚ atoms or molecules) are packed closely together. As a result‚ a solid has a stable‚ definite shape‚ and a definite volume. Solids can only change their shape by force‚ as when broken or cut. Liquid - A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. The volume is definite if the temperature and pressure are constant

Changing Leadership Styles: Flexibility Matters Introduction The articles for this week represented views of leadership theories that are based on behaviors that reveal the underpinnings of a shift in leadership styles. These studies presented empirical evidence of some intricacies of work relationships that do not follow a prescriptive outline that always leans toward favorable outcomes. Problem solving and adaptive leadership are key components to the decision making process‚ according to

States of matter are the distinct forms that different phases of matter take on. Historically‚ the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions
