It merges gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. It is chiefly noticeable in the autumn, when the apples are falling off the trees. It is by far the weakest force known in nature and thus plays no role in determining the internal properties of everyday matter. Gravity, it’s actually a real thing and we’re used to that but keep in mind people didn’t always think that. That we do not have a theory of quantum gravity is currently one of the biggest unsolved problems in the foundations of physics. Note: Although the term centre of gravity is widely used, the same imaginary point in a body may also be called the centre of mass, since weight and mass are proportional in an uniform gravitational field. The Centre for Gravitational Physics (CGP) was founded to undertake research and development for instrumentation for the detection of gravitational waves.
