Amy Arthur. Published: March 27, 2020 at 1:03 pm. With commercial spaceflight on the horizon, scientists are racing to understand what being off-Earth will mean for the human body. Psychologist Dr Elisa Raffaella Ferrè wants to know how gravity, or a lack thereof, will change the way we think.
23 lut 2017 · Gravity is one of the four fundamental interactions that exist in nature and is essential for understanding the behaviour of the Universe, and all astrophysical bodies within it. Yet it remains puzzling.
By observing the motion of planets and other objects in the Solar System (e.g. comets, asteroids, moons, and man-made spacecraft), we can learn a great deal about the behaviour of gravity.
Gravitational waves are a new branch of astronomy, providing a complementary way to study astrophysical systems to the standard light-based observations. Researchers use GR to provide “templates” of many possible gravitational wave signals, which is how they identify the source and its properties.
2 mar 2016 · Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects. Image source: T. Pyle / Caltech / MIT / LIGO Lab.
12 maj 2020 · Philosophy of physics examines such concepts as the nature of space, time and causality, the reality of electric, magnetic and gravitational fields in relation to action-at-a-distance, and the ontological status of mass (Lange 2012).
13 lip 2004 · We understand that gravity is a purely attractive force – it can only pull, never push – and that it is generated by any object with mass.
