Armageddon-How To Save The World

Image result for earth blowing upIn the movie Armageddon, a team of misfit oil drillers become world's last hope for survival. After an asteroid, the size of Texas, comes barreling towards Earth, humanity is given only 18 days to come up with a solution. Teaming up with NASA, the drillers plan to fly to space. Their goal is to land on the asteroid, drill an 800 ft hole in it, then plant a nuclear bomb inside. The objective is to blow up the asteroid into 2 pieces, projecting them on path to that is out of harms way. This plan would not work because the two pieces would not have enough time to separate, and they would still crash into our home planet, destroying everything. Since this catastrophe is bound to happen at some point, I have thought of a solution that might be a little more effective.

Since the asteroid is made of iron, a very magnetic material, my plan would be to use the strongest, non-destructive, electromagnet to slowly decrease it's velocity, then deflect the asteroid back into space. The worlds strongest, non-destructive magnet has a strength of 100 teslas. This is 500,000 times stronger than Earth's gravitational pull. The side of the asteroid that is facing earth would need to be determined either positive or negative, in which then the electromagnet would face back the same magnetic pole; since corresponding magnetic poles repel each other. To add to the strength of the magnetic forces, multiple electromagnets could be strategically placed to help contain and slow the asteroid. With the massive asteroid traveling at 22,000 mph, the opposing magnetic forces would hopefully be strong enough to slow down the asteroid completely, and force it back into space, ridding earth of danger. As stated in the movie though, there always needs to be a back up plan. So in addition to using magnetic forces to counter the velocity of the asteroid, governments could also aim multiple nukes at the giant space rock. With nukes having a potential energy of 1 megaton, multiple nuke hits to the asteroid would substantially help the slowing and redirection of it.

    Well... that's an interesting idea. Iron is not technically magnetic, but rather is ferromagnetic. That means it doesn't normally have a magnetic field of its own, but if placed in a magnetic field can have a magnetic field induced in it. This induced magnetic field will always be such that the piece of iron is attracted to the source magnet (iron filings always cling to a magnet; they are never repulsed from it). That point aside, I also have a question as to how you are going to keep your magnet (or magnets) in place while they are pulling on this asteroid. Remember, the asteroid is traveling at 22,000 mph. Where are the magnets going to be. Finally, you didn't do much to demonstrate that your plan would actually work. You gave a strength for the magnet, but that was about it.

Fast and Furious 7: The Skyscraper Jumps

Image
      If you have seen any of the Fast and Furious movies, then you would know that they are filled with ridiculous stunts. If you have seen the whole franchise, though, then you have probably noticed that the group of thuggish street racers, inexplicably become somewhat of trained, super-agent-like, fighting machines. By the seventh movie in the series, of course, the crew basically goes from street racing for money, to becoming a super team, pulling off insanely ridiculous missions.   In Fast and Furious 7, Dom( Vin Diesel) and his crew take a trip to Abu Dhabi to recover a speeddrive. The only problem is they have to steal it from a billionaire's skyscraper penthouse. They gain access to the billionaire's house by attending his party, but like always, things go wrong. A commotion of fist fighting, and gunfire errupt, and  Dom and Brian( Paul Walker), who are in desperate need for an escape plan, figure their only option is to drive out of the skyscraper into another.

Climate Change

The source I read is the Climate page of the NASA website. It lists tons of ways how climate change is shown to be happening. It starts off by saying the satellites orbiting Earth and other technological advancements have allowed scientists to see climate on a global level, and how there is clear evidence of it. Global temperature rise is one of them. The surface temperature of earth has risen about 2 degrees Fahrenheit since the 19th century, and continues to rise today. Most of this warming has occurred in the past 35 years. This can be directly related to the advancement of technology and its use of fuels that emit carbon dioxide and other greenhouse gases. Sixteen out of the seventeen warmest years occurred since 2001. Along with warming surface temperature is the warming ocean temperatures. The earth’s oceans have absorbed much of this heat increasing its temperature by 0.302 degrees Fahrenheit since 1969. With the earth’s surface and ocean temperatures rising, it has caused glac

Mission Impossible III

This was the first Mission Impossible movie I have actually sat down and watched. Overall I was entertained the whole time and enjoyed the over-the-top action stunts. While these stunts were exciting to watch, there is always the question of if they are possible or realistic. The first scene I will be analyzing is the scene where Ethan Hunt goes to save his wife and calls Benji to find out where she is. Benji tracks her location to learn that she is in a building 1 mile away, or about 1609 meters. The time it takes Ethan to get there is roughly 110 seconds. This would mean Ethan would have had to been running at an astounding 14.62m/s, or 33mph. This is an absurd measurement due to the fact that Olympic runner, Usian Bolt, who is considered the fastest man on Earth, peaks at around 28 mph. The next scene I will be analyzing is the moment when secret agent, Ethan Hunt, decides the only way to retrieve the "rabbits foot", is to swing across from one skyscraper to another in
