Black Hole
When I was a kid, I struggled to understand the meaning of a “black hole”. I was baffled how an object can suck in everything around it and never be full. In elementary school, my science teacher told us that “your chair were to contract indefinitely, it will become a black hole that will be […] Continue reading
The Event Horizon Telescope
We’ve spent the semester so far studying the greatest discoveries and breakthroughs in the history of astronomy, from as long ago as Copernicus to as recent as the New Horizons flyby of Pluto. Even more recently, however, an astronomical breakthrough was made that will surely be the subject of textbook pages and lecture slides in […] Continue reading

Black Hole Systems
Stars are capable of being pulled into the orbit of black holes due to their incredible mass. As the stars begin to orbit the black hole, mass from the star is pulled towards the black hole in the form of gas from the star’s atmosphere. NASA believes that the black hole collects the mass asContinue reading “Black Hole Systems” Continue reading
Black Holes: A great mystery of the universe
Black holes are one of the greatest mysteries of our universe. However, using just a few concepts that we have learned in class, we can understand the basic constructs of black holes. A black hole is the result of a single point in space containing extreme mass (this point is called a singularity). Similar to […] Continue reading

blog post 06
In 2019, researchers captured the first image of a black hole. They were able to do this by having all the major radio telescopes on Earth act together to simulate a radio telescope that was the size of Earth. Before this, we could only see indirect evidence of the existence of black holes. This particular […] Continue reading

Blog 4: Black Holes
Black holes have always been a topic that interests me, and this article gives some very cool insight to a possible cause for the formation of these black holes. Most black holes have been found to form as the result of stars collapsing, and then when matter in multiple black holes collides, these black holes […] Continue reading
White Holes
Most people by now are familiar with the term “black hole”- a body of high mass with a gravitational pull so strong that nothing which enters can escape from it. The idea of a black hole was born from Einstein’s general theory of relativity. Also born from Einstein’s mathematical equations, however, is the much lesser-knownContinue reading “White Holes” Continue reading

Black Holes and White Holes and Wormholes, Oh My!
They’re some of the most formidable entities in the universe: their strength is unmatched, they make their own rules, and if you get into a serious tussle with one, you’re almost guaranteed to lose. No, I’m not talking about moms. I’m talking about black holes, of course! Duh… If you’ve ever learned about astronomy, chancesContinue reading “Black Holes and White Holes and Wormholes, Oh My!” Continue reading

Blog1– the vast size of the universe
I am very excited to share this size comparison video of the universe, which I accidentally discovered last year. I watched this video for many times afterwards, and I could not stop myself gasping with astonishment at the vast size and the scale of the celestial bodies in the universe and the universe itself. ThisContinue reading “Blog1– the vast size of the universe” Continue reading

Gravitational Waves
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
