Everybody Jump

I'm not quite sure where people got the idea that something cool would happen if everybody jumped at the same time. Logistically speaking it is pretty crazy to even think something like this could be possible, but when you allow yourself to imagine a little bit, it can seem pretty cool. The writer(s) of the book What if? Serious Scientific Answers to Absurd Hypothetical Questions, have an interesting take on how the scenario would play out.

First, the entire Earth's population takes up an area roughly the size of Rhode Island, and to provide a clearer visual, the writer(s) suppose that everyone actually is in Rhode Island. Somehow, everyone manages to jump at exactly the same time, despite being crammed together, and there is a brief moment of dramatic suspense. However, nothing happens. There is a rather loud stopping noise from the combined impact of everyone's feet, but the impact is spread out and too insignificant in the context of the weight of the Earth to actually do any damage. 

Now, the people of Earth are faced with the problem that everyone is in one place and nobody except for a small fraction know where they are. People would try to use their cell phones and maybe attempt to locate friends or family, but nobody in the crowd would get any bars because Rhode Island's cell towers would not be able to deliver reception to that many cell phones. Even if T.F. Green airport somehow managed to get people on flights back to their homes, it would take them several years to even make a dent in the crowd. So if people wanted to leave immediately, they would have to steal a car and hop on either I-95, 195, or 295. The number of people leaving simultaneously would cause a massive traffic jam, and eventually people would run out of gas and be forced to abandon their cars and steal new ones. Law enforcement would cease to exist, so this would not be a major issue. Over time, people would spread out throughout the northeast, but most would stay stuck in Rhode Island, and food would become scarce. People would slowly begin to die of starvation, and the population would be reduced significantly. Those who made it out of Rhode Island would have to start a new civilization, however this would be very difficult because any two people who meet would be unlikely to speak the same language. Overall, Earth's population would be significantly reduced if everyone were to jump in one place at the same time, but the Earth it self would be largely unaffected.

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...

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...

2017 Physics Nobel Prize - Capturing Gravitational Waves

 2017 Physics Nobel Prize - Capturing Gravitational Waves Gravitational Waves Captured by LIGO Who?  Rainer Weiss, Barry C. Barish, and Kip S. Thorne - LIGO/VIRGO Collarboration What?  Observation of gravitational waves for the first time using LIGO (Laser Interferometer Gravitational-Wave Observatory. Where?  Two locations in the US - Hanford and Livingston. (See figure 1) Figure 1: LIGO in the US When?  14 September 2015 HOW?  The scientists captured gravitational waves by using an interferometer. The LIGO interferometer is a more glamorous interferometer than the original Michelson interferometer. It works through using light waves to measure gravitational interference (i.e. waves). First, one needs to understand the parts of an interferometer. The LIGO interferometer (and most) is shaped as an L. It has two 4 km vacuum tunnel arms with a mirror at each end. At the center of the arms, there is a beam splitter. Th...
