SAMPLE ALL THE FLAVORS!Increasingly, Vanderbilt instructors are incorporating blogs into their course design. Course Blogs at Vanderbilt is a mash-up of live feeds representing a wide variety of Vanderbilt courses that use blogging to help students reflect on, comment about, and introduce new ideas to course material. Click on the blog title to view the originating course blog. You can also click on the Participating Blogs tab for links to each blog.

The existence of dimensions beyond the three spatial and one temporal we experientially inhabit in our current model of spacetime has been a longstanding discussion touched on by various physicists and the scientific community. It has been suggested that gravity would propagate throughout these other dimensions, a thought brought about in attempts to somewhat unify … Continue reading Gravitational Waves and Extra Dimensions → Continue reading → Continue reading
Picture: Artist depiction of gravitational waves at work Gravity has long been one of the most transfixing ideas in our universe. For centuries, we have tried to crack the code of what exactly lies beneath our 9.8 meters per second squared. Since the apple first dropped on Newton’s head, we’ve been pining to understand … Continue reading gravity.wav → Continue reading → Continue reading
Up until recently, the only way we have been able to gather information about stars, galaxies, and the universe around us has been through the study of light. However, as of the last few years, the discovery of gravitational waves provides a new method of collecting information about the universe. Although gravitational waves were first … Continue reading Gravitational Waves → Continue reading → Continue reading
Gravity is a fascinating phenomenon of physics that is integral to understanding the universe. Gravity keeps Earth in orbit around the sun, and the Moon in orbit around Earth. Any object that has mass, also has gravity. Moreover, the gravitational force between two objects is caused by two factors: mass and distance. The gravitational force … Continue reading Gravity → Continue reading → Continue reading
A gravitational lens is an observed image of light that is bent into a circle around the gravitational objects. The general relativity theory or the curvature of the space time is used to explain this amazing phenomena. When there is a sufficiently large gravitational objects such as stars, black holes and celestial bodies in the … Continue reading Gravitational Lens by astronomical objects. → Continue reading → Continue reading
Could I really claim to be interested in astronomy whatsoever if I didn’t express my overwhelming fascination with dark matter? Seriously though, I get the feeling that most people without a solid background in astronomy don’t grasp how much of a real phenomenon dark matter is. The name itself sounds like something made up from […] Continue reading → Continue reading
Have you ever wondered what the speed of gravity is? Were you under the assumption that the force of gravity was immediate? Like everything else in the universe, gravity has a finite speed. In fact, gravity travels at precisely c, the speed of light in a vacuum. This was first theorized as a result of Einstein’s […]Continue reading → Continue reading
A very appropriate post for Valentine’s Day. NASA’s Spitzer Space Telescope has discovered a unique quality of a star and its orbiting planet that are some 370 light years away. The gravitational interaction between the two cause some vibrations in HAT-P-2 when its orbiting planet HAT-P-2b gets close. HAT-P-2b is a planet with a mass … Continue reading Blog #2: HAT-P-2’s HeartContinue reading → Continue reading
Videos of astronauts floating around inside space shuttles have led many to believe that gravity does not exist in space. However, this is simply not true. While the force of gravity affects, for example, astronauts who are orbiting the Earth in the International Space Station differently than it affects us, it still exists in space, […]Continue reading → Continue reading
The red planet is orbited by two moons, Phobos and Deimos (Greek for Fear and Panic respectively), and given the predicted fate of Phobos, the small moon has good reason to be afraid. Both moons may have originally been asteroids that were captured by Mars’ orbit, however in time, Phobos may become a ring around… Continue reading Phobos is Doomed and Should be AfraidContinue reading → Continue reading
