Gravitational waves are a fascinating concept. The thought starts from the idea that gravity moves at the speed of light. Now, at the start this sounds like a silly idea. Doesn’t the force of gravity always act on people? Yet take this example. Say the sun were to simply disappear. Not explode or change, butContinue reading “Gravitational Waves” Continue reading → Continue reading
What a ride this class has been! The sheer amount of new topics and discoveries I learned about is ridiculous, but my favorite has definitely got to be regarding the unknowns and potentials for life in our universe, or even our own Solar System! Learning about worlds such as Europa and Titan, and the liquid … Continue reading The End of a Course, But The Start of a Passion! → Continue reading → Continue reading
Tidal forces on Earth are caused by the uneven gravitational pull from the moon (and less from the sun) on opposite sides of the planet. But what are tidal forces like for objects near a black hole, a celestial object we are unable to see or explore? The information scientists have collected on black holes … Continue reading Tidal Forces and Black Holes → Continue reading → Continue reading
For many years now, the astronomy community has believed that there must be a single super-massive black hole at the center of our galaxy, but new research done by astronomers at Columbia University may have changed that belief. According to their research, data from the Chandra X-ray Observatory has shown that there are at least … Continue reading Black Holes Discovered in Milky Way Center → Continue reading → Continue reading
In a black hole, spacetime is curved infinitely. Light cannot escape. Black holes have fascinated mankind for years, but what would happen if you actually reached the event horizon? What would happen if you fell into a black hole? It’s likely you would be pulverized by other objects, burn via light radiation, experience spaghettification, or … Continue reading Blog 8: What If You Fell In A Blackhole?Continue reading → Continue reading
While the concept of black holes has become a cultural phenomenon thanks to movies such as Interstellar, it still seems like the general public knows very little about them. In order to help clarify any misunderstandings, welcome to a brief introduction on black holes. In essence, a black hole consists of a massive amount of mass […]Continue reading → Continue reading
The movie Interstellar makes more and more people curious about what black hole is. The special effects team working on Interstellar no doubt make the movie undoubtedly wonderful and also it end up advancing people’s knowledge of black holes at the same time. According to Wikipedia,A black hole is a region of spacetime exhibiting such […]Continue reading → Continue reading
Astronomers have recently discovered a supermassive black hole in a region of space that is sparsely populated. The black hole is 17 billion times bigger than the Sun (by mass), making it one of the larger black holes ever discovered. The strange part is that scientists had only ever found supermassive black holes at the […] Continue reading → Continue reading
Astronomers have discovered an enormously massive galaxy, NGC 1600, 209 light years away. NGC 1600 is an elliptical galaxy that is 17,000,000,000 billion solar masses. There are many massive black holes in the Universe (Source). In fact, there is a black hole at the center of every galaxy. It is thought that perhaps black holes […] Continue reading → Continue reading
An article by Christopher Crockett in ScienceNews came out 5 days ago that stated the amount of power output by the merging of two black holes. This was the same event detected by the Laser Interferometer Gravitational-Wave Observatory, the first detection of observational gravitational waves. The power of merger was apparently 3.6 x 10^49 watts! […] Continue reading → Continue reading
