An Engineer Claims a Gravity-Defying Breakthrough — What It Would Mean for Space Travel
What the claim is really about Reports circulate about an engineer who asserts he has developed a device that can overcome Earth’s gravity without expelling propellant. In space exploration, propulsion typically relies on Newton’s third law: to move, a system must push against something. Most engines eject propellant to generate thrust. The idea of producing…

Time on Mars: Why Clocks Tick Differently on the Red Planet
Introduction: A Crucial Twist in Relativity on Mars Albert Einstein’s theory of relativity tells us that time isn’t a universal constant. The rate at which a clock ticks depends on gravity and motion. In practical terms, clocks tick more slowly in stronger gravity. Earth’s gravity is greater than Mars’s, so, all else being equal, time…

Quantum Gravity Calculations Reveal Leading Order Dimension-6 Operators
Introduction Understanding gravity at the smallest scales remains a central challenge in theoretical physics. Recent calculations in quantum gravity have highlighted the prominent role of leading order dimension-6 operators within the framework of effective field theory (EFT). These operators capture the first, and often most consequential, quantum corrections to classical gravity when energies approach the…
