The Interstellar Wormhole

The astronauts in the movie are able to travel billions of light years in a few seconds because of a wormhole. A wormhole is when two singularities form in two points of space and they connect forming a hole which allows travel between the connection. Unfortunately the typical shape of the wormhole is a simple cylinder with space bent around it which allows it to collapse in on itself. If the wormhole would be shaped like a sphere it would be able to stay open.

The Technology In Star Trek

The teleporter in Star Trek is a necessity for the crew and the famous Captain Kirk to get back and forth from the planets. Since the ships that are used for travel are built in space with out and gravity acting on them the ship would not be build to handle gravity. Nor would it be able to leave the atmosphere. The warp drive is a necessity for the Star Trek universe since the expanse of space is so huge. The time it would take for any ship to go between any star would take so a large amount of time that all of the crew would have died.

The Bomb

The atomic bomb that was used on Hiroshima and Nagasaki was an extremely destructive force that has caused many debates since about the use of it. Some of the moral quandaries are why the bomb was even used since it is so destructive and kills so many indiscriminately. People call for the use of the bomb as a necessary evil. I believe that it is necessary because of the fear of the weapon is a deterrent to those who try and disagree with the one with the weapon.

Global Warming

The Rising Tides

Global warming is a climate phenomenon that is gradually changing the climate. It is causing warmer summers and colder winters. In the movie "The Day After Tomorrow" the film tries to show the affects of Global Warming. A polar ice cap that broke away from the Antarctica ice shelf. It raised the water so much it warmed up the water causing another ice age. This happened in an extremely short time of several weeks. In real life the water would slowly raise after years of warming causing changes in climate. The water would raise from the addition of freshwater from glaciers would cause a slight increase in ocean temperature which would expand the ocean causing flooding of all costal cities. Every year that people put carbon dioxide into the atmosphere it blocks more heat raising temperatures causing more ice to melt.

2001 A Space Odyssey

2001 may have been a critically acclaimed movie and considered one of the best movies of all times, but I simply get the feeling the director did not know how to edit a movie of empty scenes. Oh did you fall asleep? You did, well you did not miss anything the monkies are still sitting around the dirty puddle drinking. The movie is great I loved it but I think it has more empty scenes then it needs to. The movie is long by all accounts, almost three hours, it simply does not need them for example it cuts to Dave jogging around the ship for three minutes that is it nothing else happens it is just him jogging for three minutes. Besides the empty time the movie has many great aspects.

The film "2001 A Space Odyssey" is considered one of the greatest films of all time. The classical music score fits the films slow and delicate pace. One of the best scores in the film is when a space shuttle is coming in to dock with the space station. The process is very delicate and precise where an error would be a disaster, so the ship is carefully brought into dock with multiple checks and in the background throughout this process is a slow and soft piece of music. Not only then but when the astronaut Dave is having his trip near the end of the movie he is assaulted by strange and unfamiliar images and we hear a disharmonious screeching music that also makes the watcher uncomfortable. The music in this movie is very fitting and could not have been done better.

The movie has been lauded as one of the most scientifically correct movies of all time. One great example is the way gravity is provided on the space station. To create the feeling of gravity centrifugal force needs to be exerted on the objects in question which creates a normal force which is the gravity in question. The ship has a center axel which is turning at a speed that creates the force of gravity for the astronauts. Another great example is when the interview is broadcasted to the space station it takes sometime to reach it because the signal for the satellite is at light speed while extremely fast is not instant still takes time to reach the astronauts headed to Jupiter. Although it has mostly great physics one bad example is when the astronauts are on the moon they are not bouncing from the lighter gravity they are experiencing.

I love the movie it is a great film. I found the end the most disappointing at first. Once I go back and rethink it maybe he did find the beings that sent the monolith. Maybe the very trippy lights were Dave's journey through a wormhole following the higher beings. The time he spent in a room is when the put him there to make him comfortable thought out the rest of his life  like an exhibit. This may just be me trying to validate a very different ending for a movie.

Super Heroes Are Fun

(In Physics)

Super heroes are great and they normally make great movies (the Fantastic Four movies do not count). One of my favorite heroes of all time is Superman. I mean who wouldn't want to be able to fly or have super strength. Going back to the original Superman Comics he was not as strong as he is today only able to jump a measly 660 feet in the air, but that is still incredible. I was wondering just how much force it would take to allow Superman to jump like that. After some research I found this book titled "The Physics of Superheroes: Second Edition." It has a plethora of different examples of physics of superheroes and one of the chapters has my personal favorite Superman. The talks about how Superman jumps. The author, a physics professor himself, goes on to imply even superman follows the basic principal that force equals mass multiplied by acceleration. Then the author goes on to talk about the original Superman's jump of 660 feet saying that gravity is the main cause of the jump stopping ( Chapter 1 TPofSH). After some math the author says that to achieve the amazing jump height his starting velocity needs to be squared from his takeoff acceleration which is 200 feet a second which is equal to 140 miles per hour. Then to get the force applied to the ground he assumes Superman is 100 kilograms. The time assumed to jump off the ground is about a fourth of a second so he multiplied the 200 feet a second to account for time which equals 250 meters per second squared after also converting to the metric system. So multiplying Superman's mass by his acceleration gives a whopping 25000 meters a second squared. When Superman jumps he applies a whopping 5600 pounds of force to the nearby ground.

How to avoid giant flying rocks

(and the movie)

The Plan

First do not watch the movie. Well the movie it self is not bad its actually quite good. The whole premise of protecting the Earth is flawed because the asteroid would still hit the Earth. Now the real plan NASA has is suppose to work. The current plan is to launch nuclear warheads at the asteroid to gradually deflect it away from Earth. The nukes would detonate off the surface because if it actually hit the surface of the asteroid it would cause unwanted debris that would rain upon Earth. In the case of an asteroid we have a chance of preventing Armageddon.

Rail Guns the Unrealized Killer

In the movie the "Eraser" Arnold Schwarzenegger is a Witness Protection Agent. In the movie a company has developed a portable  railgun and is planning on selling it to foreign powers. An employee, Lee Cullen, of the company decides to turn them into the government for treason. Following the events of the movie Arnold eventually gets ahold of one of the railguns. Now the question is what would have happened when he fires the rail gun.
Well when he first fires the gun the recoil caused by firing it produces 26549 kilometers a second of force which would slice through Arnold killing him instantly.

The victim on the other hand receives a much lesser force of only 3745 kilometers a second. Which is still enough to kill him instantly. In conclusion the railgun in this movie is simply unrealistic because it would kill any person instantly.

Mission Impossible III

Swinging to the Finish

In the movie Agent Ethan Hunt (Tom Cruise) needs to get to the roof of a building to infiltrate it and steal a high tech weapon. Agent Hunt soon discovers the only way for him to get in the building is to come in on the roof. He decides to swing on to the other building with a rope. The question is whether or not he would be able to swing from one roof to the other. The building he starts on is 226 meters tall and the one he is swinging to is 162 with a 48 meter gap between them, so in order to make it between buildings he has to have enough rope to swing between the buildings.

The Impossible Leap

In one scene of the movie Agent Hunt needs to jump across a gap in the bridge to catch the escaping villain. So Hunt begins to run and he manages to narrowly catch onto the ledge of the other side of the gap, but is it even possible for him to make it across the gap. From my guess the gap appears to be about 10 meters wide, and to clear that gap Agent Hunt is going to need some amazing long jumping skills.

The Running Man

In one of the last scenes of the movie Agent Hunt is running through Shanghai to rescue his wife. He is being directed by his friend back the agency is directing him on where to go. He is told that he needs to go a mile and a half which is about 2 and a half kilometers through a busy city. In about one minute and 10 seconds Agent Hunt arrives at his destination after running through the city. Now is it even possible to run that fast well if you figure out his speed which is around which means Agent hunt had to run over 30 kilometers a second.
