Gravity, Newton, Einstein, and the force shaping the cosmos
The Mini Page explains gravity as a fundamental yet weak force that draws objects together and governs planetary orbits. It traces Newton’s apple tale and notes Einstein’s view that gravity involves time as a dimension, linking time and space to describe massive-scale phenomena.

The Fabric of Spacetime and Gravitational Waves
Einstein described space time as a woven fabric curved by mass. Planets orbit Sun through this curvature while gravity is the bending of space time. Mass and speed influence gravitational waves, with fast moving massive objects like black holes generating waves detectable on Earth.

Gravity and Time The Facts of Gravity
A compact overview of gravity from basic principles to its effects and applications. It explains how mass and distance affect gravity, how gravity slows time, and how GPS and LIGO relate to gravitational phenomena with references to Earth, the Moon, GPS satellites, and two U.S. gravity detector sites.

Gravity waves open new view of the universe
Gravity waves pass through matter with little interference, unlike light. They could reveal conditions less than one second after the Big Bang, offering a distinct window into early matter formation. The Mini Page credits Dr. Pedro Marionetti of the NSF for guidance.
