universe and showed the first document which becomes later a Hubble law as well as he presented the first observation of Hubble constant. In 1931, there was a meeting of the British Association in London to talk about the relationship between the physical universe and spirituality. Lemaitre talked about his observation that the universe had…

The following paper is on each of four subjects: black holes, dark matter, dark energy, and the multiverse theory. The first subject is black holes, which are regions of space having a gravitational field so intense that no matter or radiation can escape. Their existence is greatly debated over, and it still has not been determined whether they exist. The second subject is dark matter. Dark matter is a placeholder that cannot be seen. It accounts for 27% of the matter in the universe, but like…

For 13 years, the scientists of LIGO—the most ambitious, and expensive, project in the history of the National Science Foundation—had been waiting. LIGO, the Laser Interferometer Gravitational-Wave Observatory, has been twenty-five years and more than half a billion dollars in the making. It involves 900 scientists and engineers, including many whose entire careers have been spent designing, building, and preparing to analyze data streaming in to LIGO. Their goal: To confirm, once and for all,…

Examine the differences between religious and scientific accounts of the origins of the universe and the origins of the human life (30) Scientists and Theologians have been in disagreement for centuries over their views on the origins of the universe and the origins of human life. In this essay I will look at the differences of the opposing accounts. Theologians such as Arthur Peacock believe in Continuous Creation. This is the idea that God is present in the creation of the World that…

complicated questions that we to this day have no confirmed answer to but our history on this planet has lead to some clues that can possibly be the answer. Our history on this planet will be the reason why we answer these questions. The study of cosmology and modern science has lead to scientific theories that involve natural science it wasn 't just some created belief…

Gravitational theory is a theory that states any two particles attract each other with a force that is equal to the product of the two masses. Before Newton, the views on gravity and the motion of the planets, were quite different. Aristotle believed the universe never had a beginning and would never end; he believed it was eternal. Kepler’s view on gravity and motion was that the planets orbited around the sun and orbits faster the closer it becomes to the sun. Galileo believed if something…

John Kovac It’s amazing realizing where I’m sitting. Here I am right beside famous scientist John Kovac here in Wolbach Library at Harvard University. I’m astonished to see this magnificent library and I can feel the knowledge surrounding me. What’s even more impressive is that this library is mainly focused on astrophysics. As we are about to begin the interview John Kovac prepares himself my drinking a bottle of water and laying out a couple of awards he has won. What is your career? Well,…

The topic of my essay is dark matter’s importance on galaxy formation. I chose this topic because the notion of dark matter piqued my interest. It’s non-luminous so it cannot be directly observed by a telescope, which prompted me to learn more about the topic and understand it on a deeper level. Outline Introduction In this stage, the topic will be introduced, as well as a brief introduction of the subtopics that will be addressed. However the bulk of this stage will be dedicated to discussing…
