Robert Navarro, Blog Post 05 FUN FACTS ON PLUTO
Pluto’s as a planet is very intriguing. Despite being located far from the Sun; Pluto has seasonal changes due to its tilted axis (just like earth!) and highly elliptical orbit. When Pluto is closer to the Sun in its orbit, the frozen nitrogen, and methane on its surface can temporarily sublimate, creating a thin atmosphere. […] Continue reading

Composition -The solar system is primarily composed of the Sun, which makes up about 99.8% of its total mass. The Sun is primarily composed of 74% hydrogen and about 24% helium with some amounts of heavier elements. Planets in our solar system are divided into two main groups based on their composition: the terrestrial planets […] Continue reading
Understanding Auroras: The Physics of Earth’s Magnetic Light Shows
The Northern Lights The northern lights, or aurora borealis, is a display of natural light that occurs in the Earth’s sky. What you might not know is that there is another light show on Earth called aurora australis, which occurs in the southern hemisphere. So, what causes these natural and captivating lights? Solar winds are […] Continue reading
The Role of Radioactive Decay in Earth’s Internal Heat
Image: Cross Section of Earth As we have learned, the cause of seasons is the directness of sunlight a particular region of the Earth receives. What you may not know is that the sun is not the only source that heats up the Earth. The Earth actually internally generates its own heat through radioactive decay. […] Continue reading
Nature’s Closely Guarded Secret – Nuclear Fusion
We are, quite literally, made of stardust. Stars are the birthplace of many of the elements that make up our physical reality as we know it. Heavier elements (heavier than Iron, specifically) were created in a Supernova — a violent explosion of epic proportions at the end of a massive stars life. Inside of every […] Continue reading
Blog 4: Explaining Relativistic time dilation
Time seems to be one of the only immutable aspects of the universe, besides death and taxes. Many people believe that the passage of time is altogether unstoppable and unyielding. And for most intensive purposes, they are right. Indeed, time is our most precious resource and one that many of believe we have an extremely […] Continue reading

Blog 3: Equilibrium and the stability of earth
The formation of Earth and its current sustainability as they only known life-sustaining body in the universe have been caused by a number of extremely specific conditions which combine to make our planet the only one on which life is known to thrive. In this post, I will survey two of the specific conditions on […] Continue reading

The Universe’s Greatest Mystery That Threatens the Fabric of Physics
Wikipedia The foundational aspect of science is that a scientific theory that explains something about the natural world must be repeatedly tested and confirmed. If it cannot apply to every situation that meets the requisite parameters, then it is not a theory. Some information or calibration is missing, and the theory will be refined. Dark […] Continue reading

Intelligent Life Isn’t About Blind Luck. It’s About Probability.
ARS Technia The thought of other sentient life existing in the universe is one that comes up often. Among the religious crowd, many will argue that Earth’s existence is a perfect result of divine influence, that if just a few things were a bit different, we wouldn’t have evolved as we have done. Yes, we […] Continue reading
