Intersteller Wormhole Blog

In Interstellar, out main characters use a wormhole to go from one star system to another in order to find a planet which can sustain life as Earth is dying.  In order for a wormhole to be traversable, it would need to have a negative energy.  This type of matter is called "exotic matter" and it can exist.  This means that out hero's would have been able to get through.  In a wormhole, light if shown in a circular pattern, would have its cross-sections shrink as it got towards the "center" of the wormhole.  As it started to leave, it would then increase in its cross section.  Exotic matter can miraculously exist but that is not what we are talking about on this blog.  A wormhole is made by two singularities connecting.  Once the two points connect, there is a tunnel through the next dimension which is created.  In a non-traversable one, light cannot be sent through as the wormhole will collapse before the light can make it through.  These wormholes will increase in diameter and after hitting a certain point will start to shrink until it collapses on itself.  If you can go through a wormhole, it can take you to a distant place in which seems like a smaller distance.  If one were to open in our solar system it may be able to take us to another galaxy or just the next star system over.  We do not know enough about wormholes to accurately tell how far it will take you as we have not only never seen one, but never have been through one.  In a wormhole which you can go through, we do not know what the entrances look like.  Because of this there are only predictions.  One of the predictions is that it will look like a crystal ball.  In the natural world, wormholes cannot exist without something putting it there.  In the see-able universe, we do not see anything which will turn into a wormhole as it ages.  Astronomers are able to see objects which will turn into black holes but nothing with the possibility of a wormhole.  This may be because the wormhole requires two locations to connect through another dimension.  This would be very unlikely.  We can also not see if one were to form because we cannot peer into the next dimension.  As of right now I see no way that we can create a wormhole nor can I fathom a being which exists in the next dimension, as I cannot picture the next dimension.  All in all, wormholes are crazy things which contain matter which has a negative energy and also can take you from point A to point B in a short distance even if they are 100's of light-years away.

Star Trek

The movie Star Trek has many technologies which are just impossible to create at this point in time.  In the movie Star Trek there are a lot of them.  Two which I will be explaining is Warp Drive and also Teleportation.  Both of these things were required for the movie to work.  Teleportation was probably the second most important false technology they had.  Without teleportation, Kirk would have been stuck on the ice planet with no way of getting back onto the Enterprise.  Without a way back onto it, there is no way that he would have been able to take Spock's place as the captain of the ship and Earth would have been destroyed by the mining ship and red matter.  The reason that we cannot create teleportation is because we do not have a way to take the molecules that make up a person and move it to a completely different place which is over thousands of miles away.  Not only would we need to be able to get these molecules from point A to point B fast, but in the same position as they were when they were sent.  If the molecules were not in the same place as they were sent, then it could lead to catastrophic results, such as death and other things which we have no idea about because we haven't tried teleportation.  The technology I feel that is more important is Warp Drive because without warp drive, the ships would have taken way too long to get from planet to planet and there would be no way for Spock to save the elders and also no way for the Enterprise to get back to Earth.  This would also slow the movie down.  Without warp drive we are not even sure how far apart the planets are so it could not be feasible for the same people to leave from Earth and arrive at Spock's home world because they would have aged to a point where they could be dead or much much older.  Warp drive would be going faster than the speed of light.  That is not possible at this time because we cannot make anything travel faster than the speed of light due to Einstein's theory of relativity.  While Einstein's theories still hold, warp drive is not achievable.

Moral Consequences of Science

Both the movie "Gojira" and "Fat Man and Little Boy" had scientists which did not want to use the work they had created.  In "Gojira" it is clear what the position of the scientist is.  The scientist who created the Oxygen Destroyer did not want to use it because he was afraid of what the spectators would do about it.  He did not believe that the world would be safe after its use because other countries would work towards having their own oxygen destroyer and leading to wars which use it.  The scientist said that if it was weaponized it could lead to complete annihilation of any life on Earth.  This relates to the scientists working on the nuclear bombs because what actually ended up happening is other countries started working hard on making their own nuclear bombs and eventually the Cold War started which could have ended in total annihilation of most of the United States and Russia and other places.  In "Fat Man and Little Boy" most of the scientists only had a limited view on what they were doing at the start.  They only looked at it as a way to end Germany and the war.  As they got closer and closer to the end of the project, that was when scientists started to realize the impact it would have.  They were worried about the effect it would have on the people in Japan.  The head scientist, however did not think of the consequences but was thinking of the fame he would have for ending the war.  The scientist in "Gojira" was like the scientists at the end of "Fat Man and Little Boy" because they both did not want to release their creation on the Earth in fear of who else might try to recreate it and use it.  If I were on the Manhattan Project, I would not be able to finish it after realizing what the radiation would do.  I would feel responsible for any lives lost and also for what happened to Michael when he touched the core.  I would not feel right in developing a weapon which can make the area it affects uninhabitable for a period of time and also affects the innocents who are just trying to live.  This would cause me to feel responsible for ruining generations of lives and also people who were not involved in the war.  This would not be something I could bear.

Global warming: the silent killer

There are a lot of people who believe that global warming does not exist.  These people are all wrong.  Global warming does exist and can change this world tremendously.  While global warming may not affect us, it will affect our descendants.  According to www.livescience.com, the world will have the average temperature change by 1.4-5.8 degrees Celsius by the year 2100.  This may not seem like much but it would cause for the polar ice caps to melt.  If the polar ice caps melt, sea levels will rise because the ice on land will melt and add more water to the water bodies.  This would also make the animals on the polar ice caps and on the coasts lose their habitat and may cause some animals to become extinct.  This would also affect the coastal cities because the water will rise which recedes the coastline so there will be different coast lines and there will also be massive damage from this due to the destruction of the water and needed evacuation.  Since the temperature will increase, the water temperature in the polar ice caps will also increase.  There is a King Crab which has now migrated close to a continental slope.  Within a few decades the water will be warm enough for the crabs to live on the shelf.  The current wildlife has not had to live with predators such as the King Crab. When the crab moves onto the shelf, it will be like an all you can eat buffet which won't end well for the likes of the Sea Urchins and mollusks.  If the waters were not warming up, the crab would not be able to live so close to the shelf already and would have stayed at the warmer waters.  So global warming will not only affect us, but the wildlife which is around us.

2001: A Space Odyssey

2001: A Space Odyssey is a movie which I despise.  The entire film was way to drawn out with each scene taking forever.  While some say that this is a masterpiece, I say that the angles are good, but each scene was too long and also there were many unnecessary parts to each scene which drew the movie out longer than it needed to be.  That's enough about the cinematic scenes, let's get into the physics.

The physics in this movie were pretty much spot on.  They had the spacecraft rotating so that there was centripetal force holding the astronauts to the place they wanted to make the floor (the outside of the circle).  This was the first time that a method like this was used to explain artificial gravity.  There very few scenes in the movie which the physics were poor.  One such scene is when the scientists were on the moon.  During the scene where they walked towards the obelisk, they were walking normally.  This would not have been what happened because the moons gravity is weaker than the Earth's gravity.  This would cause them to have the weird walk where they bounce.

One other scene where physics was good was during the space plane flight.  The pen was floating around because the plane was not rotating.  The flight attendant also had to wear Grip-Shoes in order to walk down the aisle.  Everyone in the plane also had a weightlessness type of look (especially the professor who was sitting).  This was showing the effects of not spinning and creating a centripetal force.

Another scene which was showing good physics was when the spaceship was shown.  There was no noise except for outside added tracks.  This is showing good physics because sound has no medium to travel through in space since space is a vacuum.

Superman? Or Hoaxman?

Matt Hess

The Physics of Superheroes

The first chapter of this book was about Superman and the beginning of comics.  Superman was the first superhero to come from another planet and make it on Earth.  His original origin story was that the planet he came from was being destroyed so he was went on a spaceship by his Dad so that he may live.  Since he was from a different planet, he was a different being from humans.  The planet he came from, Krypton, has a stronger gravity which is what allowed him to have a few of his powers.  His muscles would be growing in accordance to the gravity on Krypton instead of Earth.  One of the first things Superman can do is leap over buildings and far distance.  The height he can jump is 660 feet.  His estimated mass would be 100 kilograms.  When calculating how much force his leg muscles have to exert to get up to 660 feet at the max height, they would need to push against the Earth at 25,000 kilograms meters/sec^2.  This is something that humans would never be able to do without enhancements.  This means that Krypton's gravity would be around 15 times as strong as Earth's gravity.  Superman has other powers which were introduced in later comics cannot be attributed to the difference in gravity so the comic writers had to come up with something new.  The reason that he has these powers in later comics is because of the yellow sun.  Using science this does not make much sense.

How to Avoid Armageddon: A 3 Step Process

In the movie Armageddon we witness an asteroid in a collision course with Earth.  This is bad news for anyone on Earth as it is planet-wide extinction.  In the movie they try to drill into the asteroid and blow it apart with a nuke.  After figuring out the physics of blowing the asteroid, the conclusion is that it would have still hit the Earth.  After doing some digging I soon found out about a real life plan that NASA has to deter an asteroid.  NASA is planning to capture and asteroid of a significant mass and put it into a lunar orbit (an orbit around the moon).  When it is in the lunar orbit it can be manipulated to alter the path of the asteroid which is on a collision course with Earth.  This can work because everything has a gravitational field.  If we have a large enough chunk of rock orbiting the moon, we can manipulate it so it comes close to the doomsday asteroid which will alter its course and hopefully save the Earth.  In order for this to work, the rock we use will have to be a quite large one and might have unseen consequences on the Earth by sitting out there.  The tides will be affected if the object is a large enough one when it orbits between the moon and the Earth.  The object may also affect the moons orbit around the Earth.  If we can figure out what size this rock would need to be and also figure out how to avoid the tides from becoming ruined, then this can also be used as a checkpoint on the way to Mars as well as an asteroid deterrent.

The movie Armageddon has the plan to blow the asteroid into two pieces so that it would miss the Earth.  When doing the physics and giving each value the most favorable one, we were able to figure out that the asteroid would still have hit the Earth, but in two places instead of one.  This might have been more devastating for Earth and still would lead to an awful scenario.

This guy's going to be erased

Eraser

When Arnold shot the gun, would he survive the shooting and how fast would the person who was shot go after being hit?  Here's the math:

At the speed that Arnold would be flying back, he would have either died instantly after shooting or his arm would have been torn off.  So Arnold would not be the one doing any saving in this film is real physics were applied.
The victim of this shooting would have flown back at a very fast speed so he would have instantly died and flown backwards.

Mission Possible 3

Mission Impossible 3

Agent Ethan Hunt (Tom Cruise) swinging from one building to another in Shanghai -
Could he make the jump? To find out we would need to know:
Building 1 height: 226 meters (Where he jumps)
Building 2 height: 162 meters (Lab)
X distance: 47.5 meters
Initial velocity x: -25 mph (-11.2 m/s)
Final velocity x: 15 m/s
Initial Velocity y: 0 m/s
Final velocity y: 10 m/s
Acceleration X: 0 m/s^2
Acceleration Y: -9.8 m/s^2
Time~ 18 seconds
To get the initial x velocity, I used the average human speed and took that because he runs backwards off the building.  To find the time I counted and subtracted 2 seconds for the slow motion time.  The heights were given in the movie and the x distance was too.

Drone Attack Scene
Ethan jumps a hole in the bridge.  Could he make the jump?
Hole width: 4 meters
Time: 1 second
Initial velocity: 5 m/s
Final velocity: 5 m/s
To get the holes width I used the car next to it as a guide.  The initial velocity was guessed because he started to run.  He never got to full speed so I took half of the average human velocity for his initial velocity.

Vatican City wall
Ethan repels off of the Vatican City wall.  My question is would he be able to stop that quickly and not hit his face on the ground and would it have needed more time for him to reach the ground or less time.
Y distance: 16.55 meters
Y acceleration: -9.8 m/s^2
Y final velocity: -29.4 m/s
Time: 3 seconds
