# Spotlights on relativity

### Special relativity

The basics and some applications of special relativity: Relativistic nobel prizes, the concept of relativity, E-equals-m-c-squared, time dilation and the (in)famous twins.

### General relativity

Foundations of Einstein’s theory of gravity: Einstein and soap bubbles, what is a source of gravity, the equivalence principle and free fall

### Gravitational waves

More about gravitational waves, how they are produced and how they will hopefully be detected: a survey of current detectors, how to make gravitational waves audible, the space-borne detector LISA, Einstein@Home

### Black Holes & Co.

Black holes, neutron stars and supernovae: Flight into a black hole, the black hole in the center of the Milky Way, how many different kinds of black hole are there, how black holes light up their neighbourhood

### Cosmology

The big bang and all the rest: The geometry of the universe, the formation of the first light chemical elements, cosmology and quantum gravity

### Relativity and the Quantum

Relativistic quantum theory, string theory, loop quantum gravity and other attempts to unify Einstein’s gravitation with quantum theory; the uses of extra dimensions; quantum gravity and the big bang
