Evidence of Einstein's Theory of Relativity

This happened last year, and it seemed like a great time to reiterate this discovery!

Evidence of Einstein's Theory of Relativity

In the midst of the government attempting to censor scientific findings in the United States, I found it a suitable time to remind everyone that Einstein's theory of relativity was proven with substantial evidence last year. This was a groundbreaking discovery, solving the mysteries of the theory that have existed for over 100 years.

So what is the theory or relativity? It is very complex and hard to understand, but I am going to make it as understandable as possible. There are actually two parts to Einstein's theory. They are of Special Relativity and General Relativity. Special Relativity is a theory in physics dealing with the speed of light and the consistency of the laws of physics whether an object is moving or stationary relative (hence relativity) to something else. General Relativity has to do with gravity, acceleration, and spacetime, and how they are all related.

Many people will probably recognize the equation E=mc^2. This equation means that kinetic energy (energy of an object in motion in joules) is equal to the mass of an object (in kilograms) multiplied by the speed of light (3x10^8, or 300,000,000 m/s) squared. Now, the fist part of the theory being discussed has to do with the speed of light, c.

The theory of Special Relativity involves movement and the perception of what is actually moving. How is it that you know you are moving? Movement is entirely decided upon based on a reference frame. If you are flying in a space ship, is the space ship moving through space, or is this ship stationary and space is moving around it? This is entirely dependent upon the reference frame. For the theory to hold true, and the way that most people use it, is that you are the stationary object in the reference frame. Another example of relativity is of moving cars. Pretend that you are driving on the highway, and you are going the speed limit of 65 mph. Another person passes you, driving 75 mph. From your frame of reference in your car, the other car appears to be pulling ahead of you at a speed of 10 mph. From the reference from of a stationary bystander, that car still appears to be moving at 75 mph. Now with light, it doesn't matter if you are the moving or the stationary object in your reference frame, light will always move away from you at 3x10^8 m/s. To make this clear, if the car passing you at 75 mph was light, from your reference frame, the car would appear to be going 75 mph, not 10 mph; see how that works? Unfortunately for Star Wars fans, this is why achieving light speed is never possible. Now, this theory allows for concepts called time dilation and length contraction, but we will not get into those.

The theory of General Relativity has to do with gravity. People are familiar with gravity (hopefully) being the force that pulls you toward the ground. Einstein was able to show that the effects of gravity and acceleration were directly related, and so acceleration toward the ground as a result of gravitational pull, or standard acceleration, is always at a constant 9.8 m/s^2.

Along with this theory, Einstein attempted to prove the theory of a fourth dimension which he called "spacetime" (if you are a Star Trek fan, you will love this). Before this, we were able to explain nature and physics in three dimensions, or 3-D. These dimensions allow you to move side to side (1-dimension), forward and back (2-dimensions), and up and down (3-dimensions). What Einstein proposed was a fourth dimension in space, which is called time. What does this have to do with gravity as discussed before? With the introduction of spacetime, Einstein theorized that gravity was a bending or interruption of this spacetime dimension, resulting in depressions of this sheet-like dimension. For example, if your cat is sitting on a blanket, the blanket nearest and under the cat will depress with the cat's weight. This analogous spacetime equivalent is what Einstein proposed was gravity.

With his theory of gravity being depressions in spacetime, Einstein also proposed that disruptions in spacetime were also possible when two objects in space with massive forces of gravity collided. However, this part of the theory was never proven, until recently that is. In February of 2015, scientists observed, recorded, and documented the sound of two black holes colliding in space. A black hole is a gravitational "hole" (literally a hole, for lack of a better term) with no end in which things can enter, even light, and never escape because of the immensely strong gravitational pull. Two black holes were observed colliding, releasing an audible boom which can only be evidence of the existence of spacetime. Why is this exciting for Star Trek fans? The concept of warp travel in Star Trek has to do with fusion reactions that allow them to manipulate spacetime, and thus travel through space at incredibly fast speeds. With this proof of spacetime, it is theoretically possible to manipulate it, or fold it, so that you travel from one fold to the other, then stretch it out again to go that distance in a smaller amount of time. Whether this is possible or even realistic, I do not have the knowledge or expertise to say, but it would be something.

Now that you understand relativity, you can understand the magnitude of this discovery, and its implications for science and the universe as we know it. The censoring of scientific information can be detrimental, and could hinder scientific discoveries and advancements. It is crucial that we continue to release scientific findings uncensored, and continue to unrevel the mysteries that exist in the natural universe.

11 Songs That Will Hit You In The Feels, No Doubt About It

One of my favorite things to do when it comes to music is making different playlists on Spotify. I find it so fun to go back to old songs, find new ones, and categorize them into my different playlists. We all have that one playlist that we resort to when we are really feeling some type of way — also known as a "feels" playlist. If you have one of these playlists or feel ~inspired~ to make one, here are 11 songs that are a must to add.

The Boyfriends Of The 2000s

Thank you, J14, for the Posters

J14 magazine

Every girl remembers her first crush. Even if your first crush was the boy in your kindergarten class that ate crayons, your first true love will always be the one that holds the key to your heart. Growing up in the 2000s, everyone knew who your dream guy was. Your family probably still give you grief and your best friends probably still reminisce, so it is impossible to forget your first celebrity crush. You bought a Tiger Beat magazine every chance you could just to read up about what your favorite celebrity was doing. Your room was fully decorated with posters of them, and it wasn't unusual to have fights with your best friends over who was going to marry him. If you were a 90's baby, lucky you because the 2000s were full of boys that were easy to love. I hope you enjoy a walk down memory lane and quickly realize that Bieber was definitely not the first guy with that hair cut. Here are 15 90's baby's first boyfriends.

20 Things I Learned By The Start of My 20s

No one expects you to have your life together by the time you're 20, because honestly, they didn't either.

Allyson Foutty

We are all often faced with many life challenges throughout the time leading up to our 20s. Before this time, and throughout it, we often look back at the things we've learned and how they've influenced who we are as people today. Some of my biggest influences were some of the challenges I've faced, but they've taught me 20 important things by the start of my 20s.
