@science
Near the Sun, starlight deflected twice as much as strictly Newtonian calculations predicted.
@science
Albert Einstein’s happiest thought was realizing free fall feels identical to weightlessness deep in space.
@science
Light bends downward in an accelerating rocket because the rocket moves during the beam’s crossing.
@science
Standing on Earth equals accelerating upward at 9.8 meters per second squared in deep space.
@science
A rocket can curve past a planet while its occupant experiences constant-velocity, force-free motion.
@science
The equivalence of gravitational and inertial mass has been tested to approximately one part in 10 trillion.
@science
Matter tells spacetime how to curve, and spacetime tells matter how to move.
@science
Gravity is not a force in general relativity. Objects follow geodesics through curved spacetime.
@science
Matter does not fall into a gravitational well. It follows the straightest paths through spacetime curved by mass.
@science
An orbiting astronaut follows a geodesic. The orbit is circular in space but helical through spacetime.
@science
If you feel weightless and your accelerometer detects no acceleration, you are in an inertial frame.
@science
General relativity has passed virtually every experimental test applied to it over roughly the past century.
