Morgoth: The Origins of Melkor | Tolkien Explained
In this first of three parts, we look at Morgoth's origins as Melkor, the mightiest Vala created by Ilúvatar, who rebels in the creation of the world and goes on to wreak havoc upon the Valar, the world, and its elf, man, and dwarf inhabitants. Today, we cover everything from his discord during the Music of the Ainur to his destruction of the Two Trees with the giant spider Ungoliant...

This Paradox Proves Einstein's Special Relativity
A muon is a fundamental particle with an average lifespan of around 2.2 microseconds, belonging to the family of fermions and the group of leptons, and having a spin of 1/2. Muons are created at an altitude of about 15 kilometers from the Earth's surface due to the effects of cosmic rays on the Earth's atmosphere. They travel towards Earth at speeds around 99% of the speed of light, but given their short lifespan, based on their speed, they should not be able to travel more than 660 meters before decaying. However, ...

Object So Bright That It Shouldn't Be Physically Possible...Explained
Ultra-luminous X-ray sources (ULXs) are astrophysical objects that seem to shine much brighter than what our current understanding of physics suggests they should. These objects are up to 500 times brighter than the Eddington limit, a balance where the force from emitted light counteracts the gravitational force pulling matter in. Many such ULXs have been identified, with one prominent example being SS433 in our own Milky Way galaxy. Another, M82 X2, is even more intense, emitting X-rays about 10 million times as bright as the sun, surpassing the Eddington limit by at least 100 times.

The Most Misunderstood Consept in Physics
This video is about entropy, The video begins by discussing the energy exchange between the Earth and the Sun. It explains that the Earth receives a certain amount of energy from the Sun each day and radiates the same amount back into space. This balance is crucial for maintaining the Earth's temperature. The video then delves into the history of thermodynamics, focusing on Sadi Carnot, a French physicist who studied heat engines. Carnot developed an ideal heat engine model, which led to the understanding that the efficiency of a heat engine depends on the temperatures of the hot and cold sides. This model also introduced the concept of entropy, a measure of how spread out energy is...
