We’re all attractive (by gravity!)
We like to think science has everything figured out—and it has in fact come very far to that end. But there are still many things in the world and the universe that has researchers scratching their heads. One of these phenomena is gravity, the force that attracts all objects. Sure, we know how to calculate […]

Gravity is Working Against Me
Gravity is arguably the most important aspect of our study of the universe and our solar system. Isaac Newton, famous for his three laws of motion, determined that the force of gravity could be expressed mathematically. This led him to create his universal law of gravitation. His law contains three key statements about the … Continue reading “Gravity is Working Against Me”

Blog #3
For this week’s blog, I’ve decided to talk a little bit about the intuition behind the idea of gravity. I find this theory really interesting because it makes so much sense when you think about it. As history moved along, Einstein and other physicists managed to explain the reasons why gravity acts upon objects. Gravity is due to the […]

The Consequences of the Interaction of Light and Gravity
It is astonishing the extent that gravity and light interact with one another. This is of course very fortunate for us humans when trying to understand the basic force that is known as gravity. After Isaac Newton proposed his Law of Universal Gravitation in 1687 is was generally thought that gravity was understood even though […]

Tides+Moon…Relationship?
If you spend an entire day at the beach, it is pretty obvious to notice that the tide changes throughout the day. Sometimes it comes up all the way to your feet while you lay in your beach chair, while other times the tide can be so low it seems like the water is a […]

Hearing the Universe
One of the most groundbreaking theories in astronomy has just been proven with the announcement last week that gravitational waves have been detected. Einstein had predicted these waves in 1916 in his theory of general relativity, and they were only just found today using lasers, which Einstein also laid the foundation for one year later in 1917. These […]

Space Movies – Fact or Fiction?
Our in class discussion about some space movies had me venturing down a rabbit hole about Hollywood’s misconceptions about space. The most entertaining aspect for me is how movies portray character deaths in space. Movies always find creative and dramatic ways for their characters to die in space – none of which are accurate. In […]

An Ode to Gravity
Oh, gravity. You have kept me grounded my whole life. Where ever I have traveled you have kept my feet on the ground and my head out of the clouds. I can not see you but feel your presence in all aspects of life. While some look to defy your laws, I look to embrace […]

The Potsdam Gravity Potato
Source: Universe Today The above picture is a rendering of the Earth’s gravitational field produced by the German Research Center for Geophysics’ Helmholtz’s Center in Potsdam, Germany. Known as the “Gravity Potato,” it shows that the Earth’s gravity is not as uniform as one would think. In fact, the gravitational force is a dynamic surface that […]
