Exotic Energy Concepts
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

Hello Powehi
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
Hypervelocity Stars
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

The Mysterious Black Hole
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
Blog 8: What If You Fell In A Blackhole?
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

Death by Black Hole
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

Black Hole!
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
And It All Leads Up To The Now
This semester we have studied everything from the creation of the universe to black holes to microscopic bacteria living on the bottom of the ocean floor. The range of topics covered in this class has helped round my view of the beginnings of time up until now and clarified many common misconceptions ranging from tides […] Continue reading

A Black Hole’s Diet
Source Incredible! While studying a distant galaxy, astronomers noticed a bright flare of X-rays coming from another galaxy that happened to be in their field of view. Upon closer look, they discovered that it was actually a black hole ‘eating up’ what they believe to be either an extremely large planet or a smaller brown […] Continue reading

Trous Noirs And trous noirs
For an explanation of the title, see the link at the end. If you are seriously, irreconcilably frustrated by your significant other (or lack thereof) and you never want to see your significant other (or yourself) ever again, please accept a sincere piece of advice from me: Do not- I repeat: DO NOT throw them(or yourself) in […] Continue reading
