What would happen if everyone in the world were to go to the same place and jump at the same time?
First off, it would be travel hell, with 7 billion people all trying to get to the same place in the world. Assuming that everyone would be doing this in Rhode Island, they would have to come through TF Green Airport. That in itself would take many years.

Now, if everyone were to jump at the exact same time, nothing would really happen. When the masses of everyone are added up, it does not even come close to the collective mass of the earth. Although we have 7 billion people already on the planet as is, we would need much more people to actually have an impact on the earth. The only thing that would happen if everyone were to jump, is the earth would move a very small amount. If everyone were to jump in the same place at the same time, everyone would go deaf, as the sound would be 200 decibels. The force would also cause an earthquake, and if everyone jumped on the coast in a place like Rhode Island, it may cause a tsunami.

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...
