How the Universe?

The universe is much, much, much bigger than you may think it is. I personally find it inconceivable – my finite brain does not register infinity. The observable universe, as we know it today, is 14 billion years old – this means that we can see 14 billion light-years into the universe. Within this universeContinue reading “How the Universe?” Continue reading

Wormhole Theory

Reading about the vast size of the universe, I started exploring the possibility of travelling through the it. One popular theory on the structure of space-time is a wormhole. It postulates a theoretical passage through space-time that could create a shortcut to a different spot in the universe. So far, we’ve thought about travelling inContinue reading “Wormhole Theory” Continue reading

The Cosmic Calendar

The Cosmic Calendar is created by shrinking the life span of the entire universe down into the length of the Gregorian Calendar. In this time, a human life is less than a second long and modern humans have been around for about two minutes (The Cosmic Perspective). When I think about this, it is almostContinue reading “The Cosmic Calendar” Continue reading

How Do We Understand the Size of Our Universe?

It is hard for us to truly fathom the sheer size of our universe, this is clear- the distances involved are simply too big to comprehend with just the human mind. But we have begun to understand the nature of this size, and order the magnitudes of the universe in ways we can understand. TheContinue reading “How Do We Understand the Size of Our Universe?” Continue reading

The Cosmic Calendar

Did you know that the current age of the universe is 13.8 billion years? A useful instrument for visualizing the chronology and age of the universe is the cosmic calendar. With this cosmic calendar scale, the big bang takes place on January 1 at midnight and there are 37.8 million years per day. This isContinue reading “The Cosmic Calendar” Continue reading

How Small We Are

I think that it’s absolutely fascinating to think and learn about the vast size and scale of the universe. Everybody’s been told that their problems aren’t important in the grand scheme of things and while getting a C on a test might ruin your day, your life probably isn’t going to change course because ofContinue reading “How Small We Are” Continue reading

How a Solar Eclipse Revolutionized Our Understanding of the Universe

Up until the early 20th century, the laws that our universe abided by were best described by Isaac Newton in his Philosophiae naturalis principia mathematica. Newton’s principles still hold true for the most part, as they are the basis of many introductory classical mechanics classes today. Despite being able to model the laws of ourContinue reading “How a Solar Eclipse Revolutionized Our Understanding of the Universe” Continue reading

Unfathomably Insignificant

It never fails to boggle my mind whenever I think about how vast and endless our universe truly is. Our cosmic address in the universe, beginning on Earth, to within our solar system, within the Milky Way Galaxy, within our Local Galactic Group, within the Virgo Supercluster, and within our Local Superclusters, is unbelievably microscopicContinue reading “Unfathomably Insignificant” Continue reading

And We’re Off, To the Past

Growing up, I fantasized time travel and if it would ever be possible. I watched cartoons and movies that made time travel seem so real. Of course, I got a little older and realized physical time travel would be a thing of the distant future, if it ever comes to fruition. I let the fantasyContinue reading “And We’re Off, To the Past” Continue reading

Tardigrades

Tardigrades are the toughest animals that we have yet discovered, not due to their physical strength, but rather their incredible ability to survive. People praise cockroaches for their ability to survive levels of radiation that would be lethal to humans, but the real heroes are microscopic “water bears” called tardigrades. Tardigrades are extremophiles, or micro-organisms … Continue reading Tardigrades Continue reading
