Cosmological constant

Buffers are substances that help reduce the changes in concentrations of ions which are known as hydrogen ions and hydroxide ions. The composition of a buffer in an acidic aqueous solution is combined containing a weak acid and salt of conjugate base of the weak acid. (Importance of Buffers, 2013) The composition of a buffer in a basic aqueous solution is combined containing a weak base and a salt of conjugate acid of weak base. A buffer solution resists the changes in pH therefore resisting…

With this experiment intend to prove Salem Lakes ability to buffer chemicals used in the water treatment process versus that of the Yadkin River. Using a jar test machine, simulated the addition of an acid in the form of Al2SO4, and a base NaOH to the coagulation process. Salem Lake does show a preferred buffering at higher acid doses, though Yadkin River is more efficient at the low to mid-range dose. INTRODUCTION There is a distinct difference in the buffering capacity of Salem Lake versus…

Special relativity came first and is based on the speed of light being constant for everyone. This was showed by experimental evidence that the speed of light did not alter as the earth spun around the sun. General Relativity simply supports the evidence that acceleration is found to distort the shape of time and space, and…

John Sinclair Dr. Philip Carlson General Physics I 11/28/2015 Physics Worldview Paper 6.67408 × 10-11 m3 kg-1 s-2. This number is the universal gravitational constant. It is an empirical physical constant denoted by the capitol letter G. The gravitational constant was first used in Newton’s law of universal gravitation [1] which states that any two bodies attract one another with a force which is directly proportional to the product of the two masses, and inversely proportional to the square…

such philosopher, and created 5 intriguing arguments for the existence of God. Each argument is compelling and interesting; however, it is only the first four that are known as the cosmological arguments. Although the fifth argument, the teleological argument, is worth reading, we will be giving the four cosmological arguments our attention. In this essay, not only will we will discuss the arguments from motion,…

that questions the existence of God, which he also has expressed in his article (McCloskey). The arguments were meant to be used together to provide some insight on the subject matter. The first argument that is presented in the article is the Cosmological argument. This argument attempts to infer the existence of God from the existence of the universe. In McCroskey statement…

measured by the cosmological constant, the constant states that if it is equal to zero then no dark energy exists in the universe; however, if the constant is above zero dark energy exists and the universe is expanding and below would imply a collapsing universe. The concept of dark energy is only an idea Einstein voiced and he was not proud of the construct of this concept calling it the “greatest blunder” of his life. Even so, scientists today still consider the cosmological constant, as it is…

Albert Einstein was one the most important scientists of his time. Mostly because of his discoveries and theories.Two of his theories have caught my attention: the theory of relativity or the theory of gravitation. I have found his works to be entertaining and educational while also being realistic and inspirational. Albert Einstein was a brilliant mind in his time. Well into the 21st century, he still continues to teach and give insight on important matters such as studies on gravity and…

Plato, Aristotle, the Stoics, and Aquinas each have their different views about the way our world was constructed and what is truly real, however, some of the concepts and ideas are reflected throughout one another's belief system. Plato believed in a theory he called Platonic Dualism which is the idea of resistance between spirit and matter, spirit being the higher, purer principle and matter being the lower and imperfect form of being, capable of change and corruption. He believed our world is…

component in it which exerted a negative pressure and countered the attractive force of gravity. This belief was so strong, in fact, that even Einstein, upon finding that his equations were predicting an expanding universe, arbitrarily added a cosmological constant to keep the universe static. A few years after GR was published, however, Hubble found that the universe was, in fact, expanding. Not only that, but by plotting the distances of several galaxies against their measured red-shifts, he…
