The equations of physics suggest time should be able to go backwards as well as forwards. Experience suggests, though, that it cannot. Why? And is time travel really possible?

What caused the Cambrian explosion?

What caused the Cambrian explosion?

For most of the Earth's history, life consisted of the simplest organisms; but then something happened that would give rise to staggering diversity, and, ultimately, life as complex as that which we see today. Scientists are still struggling to figure out just what that was.

Life in the universe

Life in the universe

Does life exist anywhere else in the universe? And how did it get started? Scientists are seeking the answers in the cosmos, our solar system and right here on planet Earth.

What is the universe made of?

What is the universe made of?

The Earth, the sun, the stars, and everything we can see, only comprise five percent of the universe. But what about the other 95 percent? Scientists are puzzling over dark matter and dark energy, the mysterious components that make up the rest.

Why are women paid less than men?

Why are women paid less than men?

The gender pay gap is not caused by women earning less than men for the same job. It is largely because women choose different careers and suffer a “motherhood penalty”’.

What on Earth is Wrong with Gravity

What on Earth is Wrong with Gravity

Particle physicist Dr Brian Cox wants to know why the Universe is built the way it is. He believes the answers lie in the force of gravity. But Newton thought gravity was powered by God, and even Einstein failed to completely solve it. Heading out with his film crew on a road trip across the USA, Brian fires lasers at the moon in Texas, goes mad in the desert in Arizona, encounters the bending of space and time at a maximum security military base, tries to detect ripples in our reality in the swamps of Louisiana and searches for hidden dimensions just outside Chicago.

The Pleasure of finding Things out

Richard Feynman was one of the most brilliant theoretical physicists and original thinkers of the 20th century. He rebuilt the theory of quantum electrodynamics, and it was for this work that he won the Nobel Prize in 1965. In 1981, he gave Horizon a candid interview, talking about many things close to his heart.
