Gravity behaves how Sir Isaac Newton described it: You jump up and gravity brings you back down to the ground. You reach the brow of a hill and gravity accelerates you down the other side. Simply put, gravity is a force that affects and changes the motion of things. Or at least that’s what it… Continue reading Gravity, or The Force That Makes Physicists Curse
Despite being unable to listen to it with our ears, the stars in the sky keep a melodious and constant concert. Large stellar bodies emit low and deep sounds, similar to those produced by terrestrial tubas and double basses. While small stars take pride in their high pitched voices, which resonate like heavenly flutes. But… Continue reading Stars and Their Universal Symphony
Time, as a philosophical concept, deals with thought (or the measure of how far back we can remember things). In a universe full of things, we perceive changes, and through them, time. For all we know, things have changed, have been changing and will change regardless of ourselves, which makes it necessary for there to… Continue reading Time: A Question of Infinite Speculation
Spoiler alert: we can’t. 😦 I don't know what kind of thoughts must cross through the mind of an individual who bothers pondering upon these questions, but since I like to take pride in my lack of judgement towards people and their mental processes, I will offer my opinion (as a "serious physicist") on the… Continue reading On Dark Matter: Can We Eat It?
Part II - The Neutron Star Found in the impressive constellation of Corona Australis alongside six other stellar bodies of great magnificence  lies the heroine of this story. Presently, she is the collapsed nucleus of a star, which means that she is a VERY small stellar body as well as a VERY dense one.… Continue reading Star Tales
To put it simply, complexity is a wonderful thing. Not only because it involves diversity, but also because it is indispensable. Don’t believe me? Well, just look your surroundings. Everything you see overflows in details that serve as a testament to this quality. After all, it is thanks to complex factors that we can account… Continue reading Simple or Complex: A Universal Approach
What happens when you see something? Say, for the sake of argument, this sentence you are now reading. Dismissing the whole business of how the brain processes visual stimuli, let’s set our focus on the travel time of the information you receive. And to simplify matters even further, let's also ignore how atoms absorb and… Continue reading The Physics of the Present
Part I - The White Dwarf About 120 million years ago or so, a small blue star joyfully moved in the vastness of the Cosmos. And this star, in spite of her small size of 5 solar masses, had a degree of vanity that surpassed in size even the biggest of stars. But why? It… Continue reading Star Tales
Come. Yes, you. Come. Take my hand. Come on. Just take my hand. Easy, right? Now, together we shall embark on a journey. Ah, but don't look at me with that face! Yes, I know you have responsibilities, a family, a job... yes, I already know that. But I'd like to steal just a couple… Continue reading Everything: A Story
What a question, right? In addition to personifying the Universe, this kind of interrogation exposes a premise that plays a lot with our human intuition. We can't be blamed for that, given how easy it is to assume that our sensory perceptions are right. But I do admit that cosmic complexity exceeds any common sense.… Continue reading Universe, Why so Dark?
When looking at the immensity of the known universe and imagining everything found in and out of it, to the proper mind one question becomes obvious: Why is there something instead of nothing? Yet, I am afraid that the answer to said question cannot be deduced by simple means given the laws of physics that… Continue reading Existing Makes No Sense (or so our Physics Say)
About 13.8 billion years ago, everything we know took shape right after one of the greatest events in universal history: a singularity we affectionately named the Big Bang. And what a bang it was! Although I am afraid that we were unable to appreciate such a tremendous occurrence, because, in the universal youth, we did… Continue reading We are Star Stuff
The astronomical objects we call stars are luminous spheroids whose matter is held together by gravity. And, except for our Sun, their visibility only becomes apparent during the darkness of the night. Being then that most of them look like bright spots fixed in the sky, lacking the abstraction of Van Gogh's paintings. But it… Continue reading The Marvel in Our Stars
We used to think that the Universe was made of small, invisible dots of energy, pushing, turning around and buzzing altogether. And that, through the particular arrangements these took and they way in which they'd bounce against each other, all sorts of physical matter could be produced. Artistic impression of an atom. Later on we… Continue reading A Look Into the Fabric of Space-Time
Everything we know started with a bang. Not the usual bang that we regularly associate with the firing of a gun or fireworks, given our limited perspective. Rather this was a cosmic bang. Which means that, instead of exploding, something began to expand. And boy, oh boy, did that something really expand! Graphic representation of… Continue reading The Something Before the Nothing
Throughout all my life, I have always been the kind of girl that would ask many questions. Some for genuine interest’s sake and some others for the sake of boggling the minds of adults. What can I say? I’m also quite the jester. However, this article is not going to expressly speak about said mannerisms.… Continue reading A Subversive Take on a Physics Mystery
