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.

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.

Is There a Shadow Universe?

It appears we live in a universe filled with light. But scientists are now certain there is far more matter in the dark portions of our universe.

Physics

Can We Survive the Death of the Sun?

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.

Science

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.

Is Luck Real?

Do you make your own luck or does luck make you? We find luck, good and bad, in casinos, basketball courts, genetics labs and the subatomic world. It's a journey that will radically revise your understanding of the laws of nature and the human brain.

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.

When Does Life Begin?

We can all trace our lives back to a beginning. But what defines the beginning? Is it the moment when two cells unite? Or does something have to know it is alive before its life can begin?

Nature

Can Our Minds Be Hacked?

Our minds store our entire lives, our memories and our deepest desires. Tell no one, and our thoughts remain our own. But our brains are biological computers. Computer hackers can tamper with our email. Could brain hackers someday be able to rewrite our thoughts?

Why Do We Lie?

Do you sometimes tell a lie? Why? Is it human nature to lie?

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.

Worried about black holes? Consider this: Every time you accelerate - you generate an event horizon behind you. The more you accelerate away from it the closer it gets. Don’t worry, it can never catch up to you, but the Unruh radiation it generates sure can.

Jupiter: Close Encounter

Can Jupiter unlock the secrets of Earth’s formation? How did a team engineer a spacecraft to endure a toxic mix of radiation and gaseous turbulence? After a five-year journey, the moment of truth is finally here. Jupiter: Close Encounter delivers a comprehensive, hour-long look at the unprecedented, amazing, and utterly extreme journey of NASA’s heavily armoured Juno Spacecraft on an odyssey to the largest planet in the solar system. Anchored by DAILY PLANET Co-Host Dr. Dan Riskin from the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California, Jupiter: Close Encounter follows NASA’s Juno Spacecraft mission as it attempts to enter a “polar orbit” around the king of the the solar system for the first time ever on July 4. The landmark mission will study the planet’s spectacular auroras, seek the inner-most core, and wade into Jupiter’s Great Red Spot. The gripping one-hour special introduces viewers to the dedicated and incredible team behind the high stakes-mission – scientists determined to provide new answers to the mystery of the solar system, Earth, and life itself.

Saturn

Saturn is the crown jewel of the solar system, beautiful and fascinating. It is a gas giant, and has a broad set of rings made of ice particles. Moons create gaps in the rings via their gravity. Saturn has dozens of moons, including Titan, which is as big as Mercury and has a thick atmosphere and lakes of methane; and Enceladus which has an undersurface ocean and eruptions of water geysers. While we are still uncertain, it is entirely possible that either or both moons may support life.
