The Martian Review

By: Maverick Raymundo The MARTIAN's Astronomy ( PGP ) From this week's featured film, the Martian was a really entertaining movie at a considerable dramatic pace. Against the ten cliches (that Hollywood presents) described by Philip Plait, there were a few that were played out and some that were not. Here are the points used by the author that will be compared to the movie. Sounds In Space Sounds for most of the movie (conversations and sound effects) were on a planet. When the crew was talking to each other they had spacesuits that was filled oxygen where sound can propagate. However, when Mark cuts a hole in his suit and air was released it shouldn't have made any noise at all. It should've been as quiet as Captain Lewis's assistance navigation pack. Dense Asteroid Field There weren't any encounters with any asteroids as the whole movie was about the rescuing of an abandoned man on Mars. It would've been interesting but pushing the lim...

The Day After Global Warming

The Day After Global Warming (RP) G lobal Warming Source: https://climate.nasa.gov/evidence/ NASA begins by describing Earth’s varying orbit attributing to the amount of solar energy entering would determine glacial cycles since the last ice age. However, NASA claims that the current warming trend upon the globe is caused by the growing rate of human activity in the modern climate era. By comparing the atmospheric CO2 levels from 800,000 years ago to the present (graph) shows the irregular trend increase since the beginning of the Industrial Revolution. By using ancient evidence such as tree rings, coral reefs, ocean sediments, and layers of sedimentary rocks would show how global warming consequently is occurring ten times faster. Some evidence for rapid climate change listed by them are: Global Temperature- Results portray that average surface temperature rose around 2 degrees Fahrenheit since the late...

Twin Paradox ("Contact")

Twin Paradox Portrayal In the final minutes of the movie, "Contact", displays Ellie travelling through a wormhole for hours and returning back to Earth quickly as if she had never left. The movie wants to make an argument that the astronomer underwent a twin paradox when the video capture recorded 18 hours of film. However, common misconception in movies about special relativity is when an individual experiences time different than . Relativity Postulate states that laws of physics are the same in every inertial reference frame. This would mean any observer that is not affected by an outside force or acceleration. Many would argue that since there are no absolute time and velocities, observers experience them relatively. Both observers from Earth and space can validly argue that time was running normally around them and that they are at a standstill as everything moves around them. This physical portrayal is actually not a paradox since one obse...
