Known Universe: The Biggest and Smallest

Violent Universe offers something for everyone.

The shape of the universe is determined by a struggle between the momentum of expansion and the pull of gravity. The rate of expansion is expressed by the Hubble Constant, Ho, while the strength of gravity depends on the density and pressure of the matter in the universe.

What’s the hottest place in the universe? What’s it like inside a Black Hole? This video climbs the power scales of the universe, from the coldest and bleakest reaches of our galaxy on out to the hottest and most violent places known.

A discovery of historic significance was made while searching for planets beyond our Solar System. It was a planet a little larger than Earth and it was seen orbiting a red dwarf star known as Proxima Centauri.

Some of the most extraordinary discoveries in Science are explained by the work of one man— Albert Einstein. Even after 100 years of announcing his Theory of Gravity / General Relativity, Science continues to be moved by it.

Cosmology, the study of the universe as a whole, has been turned on its head by a stunning discovery that the universe is flying apart in all directions at an ever-increasing rate.

Each of us, in the immortal words of the American poet Walt Whitman, “…are the journeywork of the stars, no less than the leaves of grass.”

“So, the universe is absolutely huge. Imagine yourself driving down a road…” Thus starts this playful and information-packed four minute journey through the universe.

Our Solar System has a mysterious zone that holds the clue to our origins. NASA has been trying since 2006 to gain access to this zone aboard the biggest rocket yet.
