Nobel Laureate in Physics Roger Penrose (Oxford) speculates on what others are saying - and not saying - about his groundbreaking theory.

Astrophysicist Scott Tremaine (Institute for Advanced Study) describes the intriguing relationship between galaxies and the enormous black holes at their cores.

Nobel Laureate in Physics Anthony Leggett (Illinois) describes the so-called Anthropic Principle that some invoke to answer the "fine tuning problem" of cosmology.

University of Chicago cosmologist Rocky Kolb describes the history of dark matter: how it was overlooked by most physicists for decades together with current hypotheses of what it might be and experiments to determine which one is valid.

This video is answering the question of how big is an iceberg.

The death of massive super giant stars creates neutron stars, let's learn how that happens!

This video will explain and illustrate how to describe and measure rotational motion.
