How The Universe Works S07e07

How the Universe Works is the greatest story ever told, the creation of everything. The programme investigates how the Universe came into existence out of nothing, and how it grew from a miniscule point, smaller than an atomic particle, to the vast cosmos we see today.

New discoveries reveal the power of microscopic alien organisms. The discovery of extraterrestrial life might face an impossible challenge: the physics of the universe itself.

Quasars are the brightest and most powerful objects in our universe, and though they have shaped the cosmos, they might ultimately destroy everything that exists.

New discoveries are causing astronomers to question if the Big Bang really happened, and using the latest science, they investigate if it wasn't just the start of our universe but many mysterious multiverses.

Dark matter is the biggest mystery of the cosmos. Scientists know that it has been vital to the universe since its birth, and new discoveries reveal that it could create black holes, cause mass extinctions, and might even shape life on Earth itself.

Spacetime is the secret structure that controls our universe, and this strange four-dimensional substance controls time, light, and energy. It will also determine how our universe will end.

Interstellar space is the space between the universe's stars and new discoveries reveal that it's not empty and unremarkable as previously thought, but filled with weird objects and strange phenomena that might hold the darkest secrets of our cosmos.

Black holes are not the violent monsters people think they are, and new discoveries reveal that they might have been essential to creating stars, giving light, and building the universe itself.

Discoveries of new planets have revealed countless worlds much stranger than Earth. Some of these strange worlds don't have stars; others are made out of diamonds. Will we ever find a planet like Earth, or are these distant worlds stranger than fiction?

Dead stars may be the key to understanding the cosmos. New research proves white dwarfs are one of the driving forces of our universe. They eat planets, they flare out in high-energy light Have scientists finally discovered how these small stars could be such massive galactic players?
