Blog #8 – Black Holes and How to Find Them
Black Holes are quite a popular topic in astronomy, but I still would like to talk about them for my last post, since they are truly revolutionary. Black Holes, in short, are gravity’s ultimate victory over stars. After a star supernova explosion, the core of a star remains. But if this core weighs more than […] Continue reading
A Tiny Black Hole?
Black holes have always fascinated me, so here I am, writing a second blog post about them. I recently read a sci-fi novel that involved a man-made black hole. It was incredibly massive, but only the size of a pinprick. This led me to wondering, what are the smallest black holes we’ve discovered in real […] Continue reading
The Other Side of a Black Hole
Based on Einstein’s theory of relativity, black holes have a theoretical opposite know as “white holes”. Rather than it being impossible for matter to exit (as is the case with black holes), it would be impossible for matter to enter a white hole. Physically, it would look very similar to a black hole: the only […] Continue reading
Wrapping Up
Looking back at my first post on this blog, it’s cool to see that my first and last posts touched on black holes. I accomplished exactly what I set out to do: answer questions that I wouldn’t otherwise set the time aside for. The most exciting part of the whole process is that I have […] Continue reading
Black Holes
If you’re like me, you’ve heard plenty about black holes, but your only real understanding comes from a couple Interstellar screenings. The movie does a pretty great job being accurate, but even the excessively brilliant characters don’t know whats going on behind the scenes. This blog is an exploration of the phenomena, equal parts for […] Continue reading
Black Holes!
Black holes are regions of spacetime where gravity is so strong that nothing can escape. I have always found the idea of black holes because they can be hard to understand or conceptualize. A weird fact about black holes is how hot they are on the outside and how incredibly freezing they are on the […] Continue reading

Black holes and spacetime | blog post II
Black holes are areas in spacetime where the gravitational force is so strong that nothing can escape. This includes forms of electromagnetic radiation like light. Current general relativistic models depict black holes as a taking on spheroid shapes, with an interminably long “tail” leading to its point of singularity. Singularity is a geometric point where […] Continue reading

White Holes
You’ve heard of black holes, right? Well, how about white holes? White holes are theoretically the exact opposite of black hole, and scientists think that they could make up a large portion of the dark matter in the universe. Where nothing can escape a black hole’s event horizon, nothing can enter a white hole’s. It … Continue reading White Holes Continue reading
Milky Way Center Home to Thousands of Black Holes
Astrophysicists at Columbia University have discovered a dozen black holes surrounding Sagittarius A*, the supermassive black hole that lies at the center of the Milky Way. The prevailing theory rests that there are supposed to be tens of thousands of black holes filling areas just light-years wide, detectable only from X-ray bursts that originate as … Continue reading Milky Way Center Home to Thousands of Black Holes → Continue reading
