Musings of an amateur astronomer

"The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself." - Carl Sagan  The Mystery of Dark Matter and Dark Energy: An Amateur Astronomer’s Journey Introduction In the last week, while reading, I came across an interesting thought: if we changed the theory of gravity as proposed by Newton, it would no longer be required to explain dark matter. This came as an astounding realization to me. Suddenly, I realized that because of one theory and one assumption, we are dealing with an unexplainable anomaly. We are doing more and more experiments, but the explanation for dark matter is just not within grasp.  Newton's Theory of Gravity Newton's theory of gravity has been a cornerstone of physics for centuries. It explains how objects attract each other with a force that is proportional to their masses and inversely proportional to the square of the distance between them. This theory has helped us understand the motion of planets, the ...
