Top Ten Examples of Bad Astronomy vs. The Martian

Image
     The film industry is notorious for defying the laws of physics, especially the laws of space physics. In  an effort to make scenes more action filled or possibly due to lack of physics knowledge, film makers will give space certain properties and characteristics that it does not possess. Philip Plait, also  known as "The Bad Astronomer", wrote a list named "Top Ten Examples of Bad Astronomy in Major Motion Pictures" which lists the ten most common mistakes that Hollywood movies make in displaying the physics of space.      I put the movie "The Martian" to the Bad Astronomy test and chronologically noted each time the movie tested an example that Philip Plait provided in his list. The first Bad Astronomy example that the movie tested was the fourth one, which speaks about the properties of light and lasers in space.      Philip Plait claims that movies wrongly show light propogating space as though space is filled with...

The Twin Paradox vs. Contact

Image
     The movie Contact makes an effort to display a realistic representation of the Twin Paradox, but the fundamental concept of time dilation was displayed incorrectly. The time dilation in the twin paradox is a result of the point of view of a stationary observer seeing a clock move slower as it moves with a constant velocity past them. This can be portrayed in the diagram below:      Keep in mind that light in a vacuum will always travel at the speed of light [c], which represents the second postulate of special relativity. The second section of the illustration above represents the actual motion of a photon in both a moving inertia frame and a stationary inertia frame. The third section of the illustration represents what a stationary observer would see as the clock moves by them at a constant velocity. Notice how the distance that the photon actually travels (2d) is shorter than the distance that the stationary observer sees. To the stationary obs...

Avengers: Infinity War Movie Analysis

Image
Avengers: Infinity War is another classic superhero movie that involves action scenes made more epic by violating the laws of physics. That being said, it took some time to find scenes that involved spotty physics. Here are a few that caught my eye.  Scene One - Cull Obsidian's Hammer Throw In the battle scene between Black Order and the Avengers in New York City, Cull Obsidian's hammer seems to be resistent to Newtons first law when it is in contact with a concrete wall, but abides by it when interacting with the ground. Newtons first law states that a body will remain at rest or move in a straight line at a constant speed unless acted upon by a net outside force.  1:38-1:42 Notice how the hammer travels straight through the building without slowing down whatsoever. Comparing this to newtons first law, it seems that the hammer is resistent to any outside forces. Now look at this scene where the hammer is slowed down dramatically by the ground. 1:55...
