With the pressing concerns regarding climate change, alternative sources of energy have been a prevalent topic of discussion. These sources range from feasible ideas such as nuclear power to ideas a bit more far fetched, such as harnessing energy from waves. While the alternative energy sources in question are all relatively feasible, there are someContinue reading “Exotic Energy Concepts” Continue reading → Continue reading
In the center of the galaxy M87, stars seem to orbit an invisible object. By observing the path of the stars, scientists concluded that there is a supermassive black hole that is dense enough to cause these motions. Although the black hole itself is invisible, we can still observe the ring of light bended by … Continue reading Hello Powehi → Continue reading → Continue reading
In 2005, the first hypervelocity star (HVS) was discovered by Smithsonian astronomers. These objects are defined as stars with very high velocities compared to normal star velocities in a galaxy. Some of them have velocities that exceed the escape velocity of the galaxy. They are thought to originate from encounters of binary stars with the … Continue reading Hypervelocity Stars → Continue reading → Continue reading
The black hole is one of the most amazing and mysterious object in our universe. In 1916, Karl Schwarzschild first provided the solution to general relativity that characterize a black hole. Black hole is the remnant of super massive star’s explosion, and it has such a strong gravitational pull that nothing can escape, not even … Continue reading The Mysterious Black Hole → 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
Unfortunately, astronomers and physicists are pretty sure you can’t just go through a black hole and pop out the other side – you will, in fact, die. The real question is, how exactly will you die?Continue reading → Continue reading
A black hole is a mathematically defined region of spacetime exhibiting such a strong gravitational pull that no particle or electromagnetic radiation can escape from it. (Definition from Wikipedia) General relativity indicates that a sufficient density can deform spacetime to form a black hole. The boundary of the region from which nothing can escape is called the event horizon. It has no detectable features when observing something traveling across an… Continue reading → Continue reading
