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...

Aerodynamics of a Golf Ball

One may wonder how a small golf ball can travel at incredibly high speeds for such long distances.  While the swing of the club is a major component, the structure of the golf ball is quite important.  Unlike a baseball or tennis ball, a golf ball has dimples all over it (usually 336 dimples).  These dimples allow the golf ball to travel without facing much air resistance.  This diagram shows how air travels around the golf ball. The dimples on the golf ball also prevent drag that would occur in the wake region, resulting in further distance.  Also due to the contact with the club during the swing, the golf ball has backspin during its entire flight.  This diagram shows the motion of the golf ball mid flight with the lift force of F. There are hundreds of different types of golf balls that a player can choose.  Some show little affect to a player's game while others can alter their performance completely.  Personally, I prefer Callaway Supers...

What Would Happen if Everyone in the World Jumped at Once?

Hypothetical and far out questions are what create great physicists and allow for us to discover and test things that have never been thought of before. Even as kids, we let our minds wander and ask questions that we never knew could be proved or disproved by physics. One question that I, as a young questioning child, and many other highly regarded physicists ask is simple; what would happen if every single person got together and jumped at once? This situation is completely unlikely to ever happen, so the only way we could ever know what would happen is through physics. Okay, so lets set the scene. Everyone, all 7 billion people, could fit into an area the size of Rhode Island, so lets assume that everyone did  travel to the smallest state in the US.  Finally, in unison, all 7 billion people jump. The push against the earth doesn't affect the earth at all, considering the Earth outweighs everyone by a factor of a mere 10 trillion. Even if the Earth were rigid and responde...
