Horizon: Is Everything We Know About The Universe Wrong?

Investigating the discovery of what is ominously being called 'dark flow', a phenomenon which could mean scientists might have to find a new way of understanding the universe

There’s something very odd going on in space – something that shouldn’t be possible. It is as though vast swathes of the universe are being hoovered up by a vast and unseen celestial vacuum cleaner.

Sasha Kashlinsky, the scientist who discovered the phenomenon, is understandably nervous: ‘It left us quite unsettled and jittery’ he says, ‘because this is not something we planned to find’. The accidental discovery of what is ominously being called ‘dark flow‘ not only … Ler mais

Horizon: How Big is the Universe?

This episode follows the cosmologists who are creating the most ambitious map in history - a map of everything in existence

It is one of the most baffling questions that scientists can ask: how big is the universe that we live in?

Horizon follows the cosmologists who are creating the most ambitious map in history, a map of everything in existence. And it is stranger than anyone had imagined, a universe without end that stretches far beyond what the eye can ever see.

And, if the latest research proves true, our universe may just be the start of something even bigger. … Ler mais

Living in a Parallel Universe

Parallel universes have haunted science fiction for decades, but a surprising number of top scientists believe they are real

In many cases, reality is weirder than any science fiction fantasy. Parallel universes have haunted novels and movies for decades and at the beginning of the 21st century in the labs and minds of theoretical physicists, parallel universes are being seriously explored as never before. Long since scientists believe that there is far more to the cosmos than we can currently detect. Particularly, quantum mechanics has made it very hard for them to ignore the idea of parallel universes.

Cosmic Dawn: The Real Moment of Creation

Horizon investigates the cosmic dawn, the moment one hundred million years after the big bang when the first stars were born

Forget the big bang. The real moment of creation was the cosmic dawn – the moment of first light. This is the scientific version of the story of Genesis.

The big bang gets all the credit for creating our universe. But in fact, the universe it gave was dark and boring. There were no stars, no galaxies, just a vast, black fog of gas – the cosmic dark ages.

But, after a hundred million years of nothing, … Ler mais
