How can the decay of muons produced in the Earth’s upper atmosphere provide evidence for the Special Theory of Relativity?
What is relativity all about? Relativistic velocity: When 1 + 1 = 1 Why can’t you go faster than light? Relativity: how people get time dilation wrong Relativity’s key concept: Lorentz gamma Einstein’s clocks Twin paradox: the real explanation Length … Continue reading

Special Relativity Part 1: From Galileo to Einstein Special Relativity Part 2: Time Dilation and the Twin Paradox Special Relativity Part 3: Length Contraction Special Relativity Part 4: Mass-Energy Equivalence or E = mc² General Relativity: The Curvature of Spacetime
How can just two rules of Einstein’s 1905 theory of special relativity lead to seemingly paradoxical changes in the perception of time?
Einstein’s classic thought experiment involves sitting on a train travelling at the speed of light. If you hold a mirror in front of your face, will you see your reflection in a mirror? How could light from your face reach … Continue reading
