What is everyone in the world jumped at once?

http://mentalfloss.com/article/54836/what-would-happen-if-everyone-jumped-once

In the scenario posed by this "What if" website, everyone in the world would stand as close as they could to one another. In this proposed scenario, the crowd is the size of the entire state of Rhode Island.



At noon, everyone jumps. This does not affect the Earth since the Earth outweighs the entire population by about 10 trillion. Humans can really only jump about half a meter high, so the Earth would only really move about half an atom.The increase of mass to the center of the Earth would increase the rate of rotation. Huge earthquakes only increase the earths rotation by 100,000ths of a second. However, the current population of the earth would need to increase by seven million times what it is now to even make that much of a difference. The collective mass of the population of the world is not enough to make a whole lot happen, and is very little compared to the Earth.

When everyone landed back on the ground, a lot of energy is delivered into the Earth. However, since it is spread out so far, only a slight pulse of pressure would go through the continent and quickly go away. There is a loud, drawn out sound from the sound of everyone's feet hitting the ground that could last for seconds.

 Everyone's cell phones would have no signal since the load caused some networks to collapse. 

The T.F. Green Airport in Warwick could handle thousands of passengers a day at a rate of 500% capacity for years without even making a dent in the crowd. Ships and rail systems fits millions, but having sufficient food and water is hard. People use their cars and back up the highways with the largest traffic jam ever. The few cars that make it out of the traffic mess only make it until about Boston or New York before running out of fuel. 

People are not very friendly. Everyone is hungry and thirsty and there are almost no resources left after a while. Soon, Rhode Island is nothing but a graveyard.The orbit of the Earth is pretty much unaffected, but the people on it definitely were.

The Physics of Spiderman

Over this past weekend after I finished working on my homework, I decided to relax and watch a few movies before going asleep. Among the movies I watched was Spider-Man 3 from 2007 and despite the movie flaws I was interested by the scenes that showed Spider Man shooting through the sky with the use of his webs that come out of his wrists. Due to this, I decided to make my blog post about the physics of Spider-Man's slingshot. After doing some research, I discovered just how much information there is on the physics of Spider-Man and how elements of Spider-Man can be used as examples for most topics learned in mechanics. For this investigation, I will not be using the horrible cliche and terrible CGI infested mess that Spider-Man 3 is but instead the all around superior Spider-Man movie of Spider-Man 2 to investigate the physics of Spider-Man's web propelled slingshot.  I want to talk about what happens in terms of physics when Spider-Man launches himself across a dista...

Physics of Black Holes...Or Lack Thereof

Isabella Jacavone To comprehend how the universe works, we must dwell into the most basic building blocks of existence; matter, energy, space, and time. NASA's  Physics of the Cosmos program involves cosmology, astrophysics, and fundamental physics intended to answer questions about the elusiveness of complex concepts such as black holes, neutron stars, dark energy, and gravitational waves. In this blog post, I'd like to elaborate on a subject that is very intriguing  to me; Black holes. And more specifically, what would happen if we got near one. A black hole is anything but a hole, but rather an immense amount of matter compacted into an extremely small area. A black hole is caused when, hypothetically, a star four times more massive than our sun collapses into a sphere no bigger than 600 square km. To put that in perspective, that's about the size of New York City. B lack holes were predicted by Einstein's theory of general relativity, which showed that when a...

Physics of Sound Dampeners and Active Noise Cancellation

Physics of Sound Dampeners and Active Noise Cancellation Sound dampening foam panels in a recording studio. ANC headphones worn by pilots and/or passengers in consumer aviation aircraft.  Acoustic treatment of soundscapes has grown alongside the sound production industry. Whether through absorption panels, diffusors and cloud panels to treat a space or headphones placed directly over the ears of listeners, acoustic treatment comes in many forms. Environments are treated acoustically to absorb excess sound to prevent sound levels from crossing a threshold above which the desired goal cannot be had. Before getting into sound dampening, we must discuss sound. Sound is produced when an object vibrates (a form of oscillation) and temporarily displaces nearby air molecules causing a wave effect as the displaced molecules collide with their neighboring molecules. Sound waves are fluctuations in pressure as the initial displacement of molecules experiences collisions that in ...
