The law of energy conservation may be the most fundamental law in physics. It says that overall energy is always conserved. It can never be created nor destroyed –...

Why does the speed of light change in different media? or Does it? How photons always travel at the same speed, but the speed of light changes. In 1905 Einstein proposed...
“Facts” that are not quite correct: 1) There is no gravity in space 2) Nothing can go faster than the speed of light. 3) Bees shouldn’t be able to fly...
“Do photons have mass?” in most textbooks, the answer is no. But is it proven that light does not have any mass? Has anyone every actually confirmed this in a...
What is Spacetime? Are space and time the same thing? Space was thought to be nothing, an empty void with no matter in it. In 1908, Hermann Minkowski postulated that...
The second law of thermodynamics states that overall entropy of any isolated system can never decrease. Entropy is a measure of the disorder in a system (roughly)...
The original paper by the authors who first performed the Delayed Choice Quantum Eraser implied retro causality. But retro causality is true only if you assume a...
Stars represent a celestial battle of two opposing forces, gravity trying to collapse the star, and radiation pressure trying to explode the star. But it comes to an end...
In 2012, the Higgs boson (the God Particle) was discovered. It’s responsible for giving mass to fundamental particles. But the scientists never measured the...
Most black holes are formed when a massive star at least 30 times the mass of our sun runs out of fuel. It then collapses uncontrolled against all other forces of nature...
