Space Travel I am still trying to decide whether my admiration for Elon Musk is because of his electric vehicles (S-3-X-Y) or his passion for space exploration. The topic of space exploration leads me to a scientific field I would like to talk about briefly, Astrobiology. Wikipedia defines Astrobiology as “an interdisciplinary scientific field concerned … Continue reading Astrobiology, The Future. → Continue reading → Continue reading
The black hole is one of the most amazing and mysterious object in our universe. In 1916, Karl Schwarzschild first provided the solution to general relativity that characterize a black hole. Black hole is the remnant of super massive star’s explosion, and it has such a strong gravitational pull that nothing can escape, not even … Continue reading The Mysterious Black Hole → Continue reading → Continue reading
The path of Mars, as viewed from the Earth. Retrograde motion is the apparent backward motion of a planet caused by its being lapped by another planet, or vice-versa.1 These two planets are usually on two different orbits, a larger one and a smaller one, and they move around the sun … Continue reading Retrograde Motion simplified. → Continue reading → Continue reading
Albert Einstein was one of the most influential thinkers regarding the fabric of the universe. Einstein’s major contribution to modern physics was his theory of relativity. The first part of this revolutionary idea was his special theory of relativity. Published in 1905, it established two major points: the laws of physics are the same in … Continue reading Blog #2: Special Relativity → Continue reading → Continue reading
In the grand scheme of the Universe, mankind has been around for an almost unfathomably short amount of time. Condensing the span of the universe into one calendar year we see clearly how our mark on the universe has barely just happened. All of what what we consider “modern” history takes place on December 31st, … Continue reading The Cosmic Calendar: Humanities Brief Reign → Continue reading → Continue reading
It’s been known for a while now that the universe is expanding, but the real question is, what is it expanding into? Well, the answer is no body really knows. Einstein’s theory of relativity makes it possible for the universe to be expanding into anything, including into itself. Because of the vast size of the … Continue reading Infinity into infinity OR an edge never to be discovered? Continue reading → Continue reading
Since the inception of ride share companies like Uber and Lyft, environmental critics have argued that these companies simply put more cars on the road, leading to increased carbon in the atmosphere. They claim that this would lead to greater air pollution. Also, many complained that an increase in these services would lessen the amount … Continue reading Lyft Making a Transition to Carbon-Neutral rides → Continue reading → Continue reading
The basis of the Fermi Paradox is that the probability of another intelligent civilization existing in the universe is so high considering the number of stars and the fact that each star has on average one planet, but this means that the probability of us finding evidence for such is also so high. The Drake … Continue reading The Fermi Paradox → Continue reading → Continue reading
A little over a month ago, astronomers in Western Australia detected the signals of stars that formed within the earliest epoch of the Universe. This discovery marks the detection of the oldest signals ever to be received, and with it, evidence for the presence of dark matter at a time when the lights of the … Continue reading Primordial Stars and Dark Matter → Continue reading → Continue reading
Halley’s Comet is named after the English astronomer Edmond Halley who first believed that there were three separate comets during the years from 1531 to 1682. He then discovered that all three of these appearances were the same comet. Edmond was the first to prove that comets could orbit the sun. It travels around … Continue reading Halley’s Comet → Continue reading → Continue reading
