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

The scale of supermassive black holes is mind boggling!

Crazy black hole video! They say learning about astronomy is a great way to feel insignificant, and nowhere is this more apparent than in the study of supermassive black holes. The amount of matter contained within these beasts is impossible to comprehend without visual aids. The black hole in the center of the Phoenix cluster […] Continue reading

A Big Snack

The physics major in me has always been incredibly interested in black holes. We haven’t spoken about them much in this course, but there are likely black holes at the center of each galaxy, and thus studying black holes can tell us a lot about galaxies in other parts of the universe. For the first […] Continue reading
