How do we know how old the Earth is? The age of the Earth was a relatively contested figure for a while, with early scientists struggling to date it with any level of precision. The first and most-well known way to set a lower bound on the age of the earth is through radioactive dating.Continue reading “How do we know the age of Earth?” Continue reading → Continue reading
We all know that light travels fast – 299,792,458 meters per second, to be precise. Still, if the sun were to suddenly disappear into a mysterious void, you and I on Earth would not notice for about 8 minutes and 20 seconds. Or would we? Would we not immediately feel the sudden jolt of ourContinue reading “The Speed of Light and Gravity” Continue reading → Continue reading
One of the coolest videos I have ever seen is the Powers of Ten video. In 1977 Charles and Ray Eames—the inventors of the Eames Office, a famous furniture company—in collaboration with IBM, created a video beginning in Chicago and gradually zooming out, transporting the viewer to the outer edges of the universe. Every tenContinue reading “Zooming Out” Continue reading → Continue reading
The Cosmic Calendar is created by shrinking the life span of the entire universe down into the length of the Gregorian Calendar. In this time, a human life is less than a second long and modern humans have been around for about two minutes (The Cosmic Perspective). When I think about this, it is almostContinue reading “The Cosmic Calendar” Continue reading → Continue reading
What is the Cosmic Calendar? Carl Sagan, a famous astronomer, promoted this idea of the cosmic calendar, that essentially is a tool used to help people visualize and understand how far apart events in the Universe are. Sagan has chronologically arranged the hallmark events of the Universe’s 13.8 billion year life span into just aContinue reading “The Cosmic Calendar” Continue reading → Continue reading
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
