Monster Black Hole: The First Image
For the first time, an image of black hole has been revealed, and experts show how they did it, what they saw, and the incredible significance of this groundbreaking discovery.
Is There a Creator?
Did our universe come into being by chance or was it created by a God? The latest science shows that the four forces governing our universe are finely tuned, leading many to believe that something must have calibrated them.

The Riddle of Black Holes
They are the most powerful objects in the universe. Astronomers now think there are billions of them, swallowing planets and stars in violent feeding frenzies, and that reality may take place on a two-dimensional hologram at the edge of the universe.
Is Time Travel Possible?
Einstein's Theory of Relativity says time travel is possible if you're going forward in time. But finding a way to travel backwards requires breaking the speed of light. Now strange-but-true phenomena like quantum nonlocality may make this a reality.
What Happened Before the Beginning?
Cosmologists agree: our universe is 13.7 billion years old. Using cutting-edge technology, scientists can take a snapshot of the universe a mere heartbeat after its birth. But if the universe was born, where did it come from?
Everywhere we look on Earth, in the most hospitable environments and in the most extreme, we find life. Yet we have only ever found life on our planet. How did the stuff of stars come together to create life as we know it? What do we mean by 'life'?
Aliens almost certainly do exist. So why haven't we yet met E.T.? We're only just developing instruments powerful enough to scan for them. One astronomer believes she may have heard a hint of their first efforts to communicate.
What Are We Really Made Of?
Our understanding of the universe has drastically changed over the last 100 years. It's on the verge of another seismic shift from LHC findings. What we find could validate theories about how the world works and what we're made of.
Beyond the Darkness
What is the universe made of? Not just stars, planets, gas, and dust! Scientists think there must be five times as much dark matter as regular matter, but they have no idea what it is; only that it's not made of atoms we know of.
