Scientists are developing an advanced quantum sensor for low Earth orbit that can detect the tiniest tremors in Earth's gravity.These barely perceptible shifts — caused by moving water, tectonic ...

Abstract: This paper uses a 42-country model of production and trade to assess the implications of eliminating current account imbalances for relative wages, relative GDPs, real wages, and real ...

Researchers from NASA's Jet Propulsion Laboratory in Southern California, private companies, and academic institutions are developing the first space-based quantum sensor for measuring gravity.

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used.

If we were living in a computer simulation, would we be able to tell we were living in a computer simulation? It's a question ...
