Cosmos : 10 - Edge of Forever -1/6

Cosmos: A Personal Voyage was produced in 1978-79, written by Carl Sagan, Ann Druyen and Steve Soter; along with Life on Earth and The World at War, it remains one of the landmark documentary series of its time, and had a lasting legacy in the popularisation of modern science.

Filmed around the world presenter and astronomer, Carl Sagan, takes the viewer from the hearts of distant Galaxies, through Black Holes and other dimensions, past Stellar Nurseries and ancient Stars to the Pale Blue Dot of planet Earth.

But in spite of this insignificance the series also celebrates the heritage of knowledge and civilisations, scientists and explorers whose shoulders we stand on.

And it delves into the stuff of life, the evolution and diversity of species that cover our world, and to the very atoms of existence itself; ultimately learning that all matter is Intrinsically linked to the Cosmos and the Stars.

Episode 10 : The Edge of Forever

"If you want to know what it's like inside a Black Hole, look around..."

The Ultimate Question: How did it all begin? How will it all end?

The questions that formed the basis of religion has been the scientific questions of the 20th Century. But answered by evidence.

From the observations of Edwin Hubble and Milton Humason the Red Shift of distant Galaxies showed the expansion of Space since the "Big Bang". To explain this phenomena Sagan takes us on a visit to the strange 2-Dimensional world of "Flat Land". And from there we can imagine the realm of the tesseract, the 4th Dimension.

But is there an end to the Universe?

The known universe contains about a trillion or so galaxies not including most of the dwarf galaxies. We are most likely sure that planets actually outnumber stars quite a bit. We now know of far more than 550 maybe closer to 560 planets around other stars. The unvierse is so vast though that most likely more than half the planets in our own solar system would not be detected if they were around the nearest star other than the Sun, that is huge.
