Behemoth black hole found in an unlikely place
Watch out, Earth! Scientists have discovered a massive black hole in our universe, one that weighs the equivalent of 17 billions suns! While the size of this black hole is very significant, something that makes it even more unique is it’s location in our universe. According to astronomers, black holes this size are almost always […]

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 […]

Gravitational Redshift
Most of us know about redshifting, a phenomenon of the Doppler effect. This is the change in frequency of a wave, both mechanical and electromagnetic, for an observer when there is relative motion between the source and the observer. For example, when an observer is moving closer to a wave source, each successive wave front […]

Travel Inside a Black Hole
Although we usually think of black holes as extremely massive objects, anything in the universe with mass can theoretically become a black hole. As this video discusses, it is mathematically possible for a black hole to form with the mass of the earth, or even Mount Everest. However, the object’s Schwarzschild radius, the size it […]

Supermassive Black Hole at the Center of Our Galaxy
Sitting at the center of our galaxy, a supermassive black hole weighing four million times the weight of our sun waits. After the class discussion on black holes, I began investigating local black holes, and discovered that there is a gigantic black hole in our very own milky galaxy. Scientists first located this black hole…

A Young Black Hole?
As viewed from Earth, most black holes are about 17,000 to 21,000 years old. Recently, however, NASA scientists discovered what may be an infant black hole (pictured below). This black hole is only about 1,000 years old as seen from Earth and is located 26,000 light years away. It is left over from the supernova […]

Destination: Black Hole
I like black holes. I like them a lot. They are in the top ten of my bucket list of destinations if I live for a thousand years. Black holes in popular culture are notorious for being very dark objects. I will try enlighten the readers about their shady origins, and hope that people see […]
