Nuclear fission of Uranium atoms

Slide 19

General Theory of Relativity (GTR)

General Theory of Relativity (GTR)

Principle of Equivalence

All objects experience the same motion in a given

gravitational field, irrespective of their mass

[Galileo's experiment at the leaning tower of Pisa]

Gravitational field <===> Accelerated reference frame

Gravity can be thought of as a distortion of space-time

Gravitational lensing:

Multiple images,

image distortion

Gravitational Redshift

[Extreme case: light is

trapped in a black hole]
