The Moon and The Tides
Did you know that tides are caused by the Moon’s gravitational pull? (Photo from The Business Insider) Usually about every 12 hours coastal places around the world experience high and low tides in a constant cycle. This is due to the subtle pull of the Moon’s gravitational forces on the Earth’s water supply. Along the […] Continue reading
Gravity on Earth versus other planets in our solar system
Exploring how gravity on different planets in our solar system is different. Gravity definition: Gravity is the force that attracts items to a planet or other body’s core. Gravity keeps the planets in orbit around the sun. Since all the planets weigh differently, and have different radius this causes the gravitational pull of each planet […] Continue reading
Gravity & General Relativity
You throw something up in the air and it falls down. Why? Gravity, obviously, everyone knows that. But what really is gravity? By most common knowledge, gravity is one of the four fundamental forces, and has a lot more to it than just making things fall. Gravity actually works as an attraction between two masses, […] Continue reading
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
