Crunch, Rip, Or Freeze, The Universe Will Cease To Exist

The rule of threes always prevails.


It's innate in human nature to contemplate on our long-term objectives in life: "What career path do I wish to follow?" "Do I want kids?" "What house do I want to live in?" For some, these objectives are within the cusp of their fingertips, while others still have a long road ahead to accomplish them. What we all share is a sense of fate, of the inevitability of the trajectory to which we ceaselessly travel.

Each path we take as humans indubitably leads to an inevitable demise: death. Just as we contemplate what happens when we die, scientists hope to ascertain an understanding of the fate of the vast universe long after we have acquiesced to the void. The uncertainty of if the soul transcends to another realm to meet judgment, or if the soul even exists, science has served as an outlet to theorize the fate of this heavenly realm.

The first modern humans appeared in Africa at approximately 200,000 BCE, but the fact of the matter is our existence is a mere grain of sand to the dune formed at the bottom of the universe's hourglass; the three theories regarding what happens once that final granule falls to the bottom are The Big Rip, Crunch, and Freeze.

The Big Bang is believed to have occurred about 13.7 billion years ago, where the entire mass of the universe began to disperse from an astronomical explosion. The Big Rip is theorized to occur 22 billion years from today and developed by Marcelo Disconzi, assistant professor of mathematics in Vanderbilt University. Collaborating with Thomas Kephart and Robert Scherrer, they discuss the nature of cosmic viscosity and current beliefs of an elusive substance composing the observable universe: dark energy.

Although it was once believed that the universe was infinite, observations have been made of it expanding at an accelerating rate! The vector driving the acceleration of the universe's expansion is coined the term dark energy, yet it is unknown what physical state this is believed to exist in. However, this undetectable substance is believed to comprise 70 percent of the entire universe. Cosmological viscosity—the tendency for the universe to resist contraction and expansion—revolved around Disconzi's as he studied fluid mechanics in neutron stars and supernovae. This led to evidence that the expansion of the universe will be infinite and that cosmic viscosity and dark energy will drive the splicing of all atoms, ripping the universe apart.

Another theory pertaining more towards our understanding of thermodynamics is the Big Freeze, also known as the "Heat Death." Believed to be the most probable and sound in modern physics, it is believed that the entropy or disorder of the universe will continue to increase until it reaches a certain value. This is in concordance with the Second Law of Thermodynamics, stating that the entropy of a system increases with spontaneous processes. The maximum entropy would result in an equal distribution of heat across the universe, making it impossible for viable energy to exist. Matter would be spread so thin the universe would simply become a desolate void.

The most optimistic theory is The Big Crunch, involving the overcoming of gravity in its strife with dark energy. As dark energy has a tendency to accelerate expansion, gravity has a tendency to pull things closer based on mass. Eventually, the force dark energy applies to expand will be overpowered by gravity, resulting in the reversal of the Big Bang as the mass of the entire universe will return to one singularity. In theory, the Big Bang and our universe can simply be one of many iterations of expansion and contraction.

These ideas are of such an incomprehensible scale that it may feel as though your personal goals are at an arbitrary scale. In comparison to the universe, they may seem to play a small role in the gears that grind the cosmos. However, while we're granted the conscious mind, we should make the most of that one grain of sand and feel liberated to raise the stakes in accomplishing our aspirations.

For as long as I can remember, I have been listening to The Beatles. Every year, my mom would appropriately blast “Birthday” on anyone’s birthday. I knew all of the words to “Back In The U.S.S.R” by the time I was 5 (Even though I had no idea what or where the U.S.S.R was). I grew up with John, Paul, George, and Ringo instead Justin, JC, Joey, Chris and Lance (I had to google N*SYNC to remember their names). The highlight of my short life was Paul McCartney in concert twice. I’m not someone to “fangirl” but those days I fangirled hard. The music of The Beatles has gotten me through everything. Their songs have brought me more joy, peace, and comfort. I can listen to them in any situation and find what I need. Here are the best lyrics from The Beatles for every and any occasion.

19 Lessons I'll Never Forget from Growing Up In a Small Town

There have been many lessons learned.

Small towns certainly have their pros and cons. Many people who grow up in small towns find themselves counting the days until they get to escape their roots and plant new ones in bigger, "better" places. And that's fine. I'd be lying if I said I hadn't thought those same thoughts before too. We all have, but they say it's important to remember where you came from. When I think about where I come from, I can't help having an overwhelming feeling of gratitude for my roots. Being from a small town has taught me so many important lessons that I will carry with me for the rest of my life.

I can't say "thank you" enough to express how grateful I am for you coming into my life. You have made such a huge impact on my life. I would not be the person I am today without you and I know that you will keep inspiring me to become an even better version of myself.

Waitlisted for a College Class? Here's What to Do!

Dealing with the inevitable realities of college life.

Course registration at college can be a big hassle and is almost never talked about. Classes you want to take fill up before you get a chance to register. You might change your mind about a class you want to take and must struggle to find another class to fit in the same time period. You also have to make sure no classes clash by time. Like I said, it's a big hassle.

This semester, I was waitlisted for two classes. Most people in this situation, especially first years, freak out because they don't know what to do. Here is what you should do when this happens.
