The Martian and Bad Astronomy

The Martian and Bad Astronomy

Philip Plait is the author of Bad Astronomy and in Chapter 24 he gives 10 examples of bad astronomy in major motion pictures. While some of these are not directly correlated to the movie The Martian some of the examples do apply.

The first example has to do with the fact that there is no sound in space. As you may or may not know is that there is no sound in space, and in most movies you can hear ships as they go passing by or maybe even explosions. Unfortunately The Martian is one of these movies that have sound in space when it is not physically possible because sound cannot travel in space. For example, when they try to save the main character and through out the entire scene there is sound from thrusters and other objects that the characters are interacting with. The second example that he list does not apply to the movie and it has to do with asteroid fields which you do not see in the movie.

The next example that is listed is about banking in space and changing directions suddenly. This scene I believe is somewhat represented within the movie when Mark is in his pod flying into space to be saved by his team mates. When he was taking off into space and started getting flung around in different directions and he blacks out is when this example is truly shown. The next example however has to do with laser beams  and being able to dodge them but in the movie there are no lasers being fired.

The fifth example that is talked about is the distance between stars and other objects in space and how long it would take to travel between these objects. In the movie I believe that this is shown relatively well because it does take a long time to travel in space. In the movie it takes the stories crew over a year to make the trip to Mars and back which is an incredible amount of time to be traveling in space. Compared to some distances this may be small but the movie does a good job of showing it takes time to travel in space. The next example has to do with aliens stealing water from planets and the lack of water in our galaxy. This is somewhat shown in regards to there not being a lot of water besides here on earth. Even in the movie Mark Watney talks about there being no water on Mars and the fact that he has to make his own to survive.

The next example talks about objects trying to escape Earth's gravity but being caught in mid air and not moving. This is not shown at all in the movie and does not have any connection to what is going on. The eighth example however is very clearly shown and gotten wrong in this movie. This example talks about the fact that if you are traveling in space that the stars that you see around you will not go passing by but rather they will most likely stay fixed in the same position the entire time that you are traveling. This is violated in a couple of scenes that show the main ship flying in space. As you look out into space through a window or as they travel the stars in the background pass by which is not what would actually be happening.

The ninth example talks about explosions in space and the shape and features of the explosion once it does happen. In most cases you would not get some cool explosion that you might see in some movies like star wars. While some movies have explosions that go out in a ring at the center of the explosion that is not the case and the explosion would most likely have a spherical shape to the explosion. In the movie this is shown in a good way as far as I am aware of due to the fact that the explosion happens and there is nothing special that happens after and it just disappears. The last example talks about the phase changing of the moon and how the phases are inaccurately portrayed over time. However, in the movie we do not get to see the moon very much and therefore it does not really apply.

    One difference between a blog post and normal writing is that it gives you the opportunity to incorporate different media (like scenes from movies) into your writing. You should take advantage of this.

Nuclear Weapons

Morality of Nuclear Weapons A lot of people talk about the morality of creating and using nuclear weapons. Most people have agreed on not using nuclear weapons and other weapons of mass destruction, but the creation of weapons is another discussion entirely. Most people are against the creation of these weapons of mass destruction however, I am not one of those people. I support the creation, not the use of these weapons not because I want to see the world burn, but because you need a way to protect yourself. If we are not the first to create a new weapon or able to make these weapons then that leaves us vulnerable and at the mercy of others who have created these powerful weapns. This was the case when we created the atomic bomb during world war 2. A lot of people were against the creation of the bombs because of the destructive potential and the fear that others would learn how to create the same weapons. However, there were those who supported the creation to set us up on top a

Interstellar

Black Holes In the movie Interstellar there are a lot of different physics topics to talk about but the most interesting is probably the black hole Gargantua. What makes black holes so interesting is that there is so little that we actually know about them yet there are some effects that we do know. What we do know about how black holes work is that they exert a large gravitational acceleration so strong that nothing can escape from it. It also has the ability to exert a very strong gravitational force on any nearby object such as planets that are nearby. This is especially important when the group of astronauts land on the ocean planet that is nearby. On this nearby planet there are these very large waves that reach towards the sky. These waves are caused by the pull of the gravitational field of the nearby black hole. The pull of black hole would rock the planet back and forth relative to the black hole. This occurrence causes the planets tidal gravity to reach towards the b

Final Blog Post

Nuclear Protection Lots of people love to watch action movies, where there is exploration, action, and most importantly explosions. In the movie Indiana Jones and The Kingdom of The Crystal Skull, there is all of these qualities and more. The movie in fact starts out with a fight scene and the goes on and shows our hero survive a nuclear explosion. Now you may ask, how did our hero survive the explosion? The answer to that is that he climbed inside a lead lined refrigerator and was sent flying off into the distance. The problem that I am looking at has to deal with projectile motion and how Indiana Jones was sent flying while hiding in this refrigerator. There are a couple of aspects that we should take into account when it comes to looking at our problem. The first aspect is how high does the refrigerator travel after being hit by the explosion. We can find the answer to this by using the equation y=1/2(Vyi+Vyf)t ,but there are parts of this equation that we need to
