From collapse to solar system

Once upon a time, there was a huge interstellar cloud of cold, low-density gas called the solar nebula. This solar nebula came about from billions of years of galactic recycling, and consists of about 98% hydrogen and helium and 2% other random elements. The solar nebula collapsed under its own gravity, and BOOM! the Sun […] Continue reading

Blog 4: Explaining Relativistic time dilation

Time seems to be one of the only immutable aspects of the universe, besides death and taxes. Many people believe that the passage of time is altogether unstoppable and unyielding. And for most intensive purposes, they are right. Indeed, time is our most precious resource and one that many of believe we have an extremely […] Continue reading

Gravitational Mysteries

by me The idea of gravity, the fundamental force that controls how objects move in the universe, is both intriguing and mysterious. Gravity is a force that pulls objects toward each other; it controls everything from an apple falling from a tree to a planet’s orbit around a star. It’s a force that operates over […] Continue reading

Understanding Gravity

There are many different ways to visualize how gravity functions. However, one of the best way I have found to visualize gravity is with strings and using the center of mass. Gravity is the weakest force of the four fundamental forces, however, it works over an infinite amount of distance. I put this in perspective […] Continue reading

Fun Fact About Gravity

One thing that has always fascinated me is how gravity and time are interlocked. Specifically, people at higher altitudes experience time relatively faster than people at sea level. This is due to a concept called gravitational time dilation. Time dilation comes from Newton’s theory of relativity. Basically, the more gravity you feel, the slower you […] Continue reading

How Gravity on the Space Station Actually Works

Chris Hadfield Juggling Tomatoes on the ISS (2013) As we have all observed, astronauts on the space station experience what appears to be zero gravity. You might think this is because the space station is far from Earth, and the force of gravity diminishes with the square of the distance, according to Newton’s Law of […] Continue reading

Blog Post 2 – Gravity

“Animation vs. Physics “ by Alan Becker on Youtube Before we get started, the video linked above is phenomenal. If you have any interest in physics, astronomy, astrophysics or anyting related, I cannot recommend this video enough. It encompasses all of these topics in a fun animated way that also gives Interstellar vibes with its […] Continue reading

Gravity holds the universe together

Gravitational force, why planets have orbits, and how we know that black holes exist When you think of gravity, you might think of the force that makes apples fall on people’s heads (talking about you, Newton!). But it’s also why planets have orbits! Any two objects in space have a gravitational force between them. Kepler’s […] Continue reading

Tides During a Superstorm

As we know, the moon controls the tides, but what happens when the perfect circumstances come together and a storm is involved? This is part of what happened during Hurricane Sandy. In my Introduction post, I shared with everyone I am from New Jersey and love going to the beach, so back in 2012 when […] Continue reading

Escape Velocity and Space Exploration

In our generation, space exploration has been an extremely valuable way to learn more about our solar system and our galaxy, the Milky Way. It is astounding that humans have been able to set foot on the moon, and that astronomical research centers have sent probes to a variety of astronomical objects within our galaxy, […] Continue reading
