The Universe’s Greatest Mystery That Threatens the Fabric of Physics

Posted on March 2, 2024 by Landon Peaden

Wikipedia The foundational aspect of science is that a scientific theory that explains something about the natural world must be repeatedly tested and confirmed. If it cannot apply to every situation that meets the requisite parameters, then it is not a theory. Some information or calibration is missing, and the theory will be refined. Dark […] Continue reading →

Interstellar Travel using Warp Drives

Posted on April 4, 2022 by isaiandrade01

Perhaps the most challenging obstacle between humans and interstellar travel is the distance it would take to traverse the light-years of distance to even the closest stars. The closest star to Earth, besides the Sun, is known as Proxima Centauri, at about 4.25 light-years. For reference, the fastest a human spacecraft has traveled was a […] Continue reading →

White Holes

Posted on March 19, 2022 by evang914

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 →

Warping the 4th Dimension

Posted on March 17, 2022 by isaiandrade01

The concept of time dilation is one of the direct results of the theory of general relativity proposed by Albert Einstein, and it explains the effect of gravity on time. The theory of general relativity describes space as a three-dimensional space with time being the fourth dimension through which space is moving, creating the spacetime […] Continue reading →

How a Solar Eclipse Revolutionized Our Understanding of the Universe

Posted on January 19, 2020 by Dan Pitagora

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 →

Newton’s Law of Gravitation and General Relativity

Posted on February 10, 2019 by richardficek

Isaac Newton’s law of universal gravitation first appeared in the Philosophiæ Naturalis Principia Mathematica in July 1687. It describes why that apple fell on Newton’s head (as some stories would have it), why we stay rooted to the ground (without drifting off into space), and why the Earth is locked in orbit around the Sun (among … Continue reading Newton’s Law of Gravitation and General Relativity → Continue reading →

The Consequences of the Interaction of Light and Gravity

Posted on February 16, 2016 by 2016spaceodyssey

It is astonishing the extent that gravity and light interact with one another.  This is of course very fortunate for us humans when trying to understand the basic force that is known as gravity.  After Isaac Newton proposed his Law of Universal Gravitation in 1687 is was generally thought that gravity was understood even though […] Continue reading →

Smiling Galaxy Cluster Found in Space!

Posted on February 13, 2015 by agiantchicken

That’s some intense gravitation lensing! A cluster of galaxies was recently discovered by the Hubble Telescope (AKA, uber relevant to class!) that appears to take on the shape of a bright smiling face. The galaxy cluster, known as SDSS J1038+4849, recently had the above picture taken by said telescope. While it may appear to us that […] Continue reading →

Trous Noirs And trous noirs

Posted on March 19, 2013 by ibrahim2016

For an explanation of the title, see the link at the end. If you are seriously, irreconcilably frustrated by your significant other (or lack thereof) and you never want to see your significant other (or yourself) ever again, please accept a sincere piece of advice from me: Do not- I repeat: DO NOT throw them(or yourself) in […] Continue reading →

Relativistic Doodles

Posted on March 19, 2013 by ibrahim2016

This post explains how my illustration of general relativistic time dilation works. This is the parent post. Here is an image of a simple classical timeline: There are 2 observers: green and red. They have their own watches. The red observer shoots an arrow towards the green observer. The position of the arrow vs. the […] Continue reading →
