We are all at the mercy of the Sun. Its glowing disc sustains nearly all life on Earth. But the Sun also holds a dark secret: someday, our aging, expanding star will bathe the Earth in a fiery holocaust. Everything we know will turn to hot, bubbling, plasma.

When Did Time Begin

We float along the river of time. But does that river have a source? Where did time come from? Some believe time and space are one thing, and the Big Bang started the cosmic clock. Others believe the universe existed for almost half a million "years" before light could move and time began. Still others say time is older than our universe. But what if time itself is an illusion? Incredible new experiments may hold the answer. One groundbreaking experiment gives us the power to punch holes in time…and another may create a machine that operates outside time’s boundaries!

Is Gravity an Illusion

We feel it every moment of our lives but for physicists, gravity is the longest running unsolved mystery of the universe. Why do all objects that have mass pull on one another? Cutting-edge theories are proposing unexpected answers.

Can We Survive the Death of the Sun?

Can We Travel Faster than Light?

It's called the speed limit of the universe. Einstein blew all of our minds when he worked out the Theory of Relativity, and showed that space and time were malleable substances. He also theorized that we as humans can never travel faster than the speed of light, which leaves the stars and other galaxies almost impossibly out of our reach. But the dreams of Star Wars and Star Trek are not dead. In fact, there could be ways to travel faster than the speed of light - and some of them are already being tested in labs around the world.

Physics

Is Reality Real?

Do we live in the "real world" or is it all in our mind? Our perception of reality is controlled by society. Thanks to "the optimism bias", we make unrealistic assessments about our own reality. Human senses capture only a small part of nature.

Science

How Does the Universe Work?

Quantum theory, the best explanation of how atoms and anything smaller behave, is so weird even scientists who have mastered it find it baffling. But bit by bit scientists are finding maybe it's not so weird as comparable behavior is discovered in our every day world. It's just that no one noticed before.

Will Sex Become Extinct?

Every single person who has ever lived was created from the genes of one man and one woman. But human sexual reproduction, unchanged for millions of years, is about to undergo radical change.

Do We Live in the Matrix?

Our universe seems real. But what if it’s a videogame? Scientists in a variety of fields are taking seriously the possibility that we live in a virtual reality. Maybe the Big Bang was just the moment someone flipped the switch and turned on our universe. Maybe what looks random has already been programmed to happen. If some advanced civilization did design and program our universe, would we ever know? Scientists are looking for glitches in the laws of the universe that may uncover its hidden code.

Can Science Make Me Perfect?

Anatomist Alice Roberts embarks on an audacious scientific stunt - to rebuild her own body from scratch, editing out errors left behind by evolution; to create the perfect body. With the help of one of the world's best virtual sculptors, Scott Eaton, and top SFX model maker Sangeet Prabhaker, Alice creates a life-size model of the perfect human body, to be revealed in front of 150 people at London's Science Museum. Through natural selection, animals have evolved incredible biological designs, from supersharp senses to superpowered limbs. Alice is on a hunt to find the very best designs the natural world has to offer and use them to fix the flaws in our own human anatomy. By meeting leading medical and animal experts, Alice finds out what the body's biggest problems are, and how amazing adaptations in the rest of the animal kingdom could provide inspiration for her perfect body. Using incredible CGI to morph her existing body into new forms, she demonstrates how rethinking our bodies could overcome millennia of natural selection. Finally, in an epic reveal, Alice unveils the life-sized model of her perfect self in the Science Museum. There, in front of an audience, Alice meets the 'perfect human' version of herself for the first time. Ambitious, audacious and packed with cutting-edge science, Can Science Make Me Perfect? With Alice Roberts challenges everything you thought you knew about the perfect body.
