Can nothing really be nothing? Can empty space really be empty? Could the entire cosmos really have simply emerged from ... emptynothing? Scientists are peering into the void, searching for an answer which may hold the key to knowing whether the universe is fated to expand into oblivion - or contract again like an enormous, beating heart. The quest to understanding "nothing" promises to uncover the very fabric of the universe - and, perhaps, our own eventual fate.moreless
What is it that makes you, you? Are we born with an innate sense of self - or can our identities be altered? Can our deepest, most traumatic memories be changed, or erased - and would that change who we are? To find out, scientists are probing the brain - and peering into the mind. But is it perhaps the soul which holds the key to who we are? As we evolve over time, our appearance transforms, our ideas and ideals sometimes change - but seldom does our inner sense of self. We spend our life trying to understand who we really are - but should we have known all along? Do we ever really change?moreless
Could the key to understanding the universe be biology and not physics? Could it be that the universe is actually alive - a self-replicating super-organism with a heartbeat and a mind? Is it conscious of us - or does it only exist because we are conscious of it?moreless
What do aliens look like? Planetary Scientists and Biologists use what we know of evolution on our own planet combined with information from newly discovered planets that could theoretically support life, to theorize on how an extra-terrestrial might look. Morgan Freeman narrates.moreless
Is death inevitable? Scientists are searching for ways to extend human life and some of the results are startling. Could immortality really be on the horizon?
Negative energy, cosmic strings, wormholes, warp drives, waves of space-time - can any of these things help get us to out into the cosmos by traveling faster than the speed of light? Physicists speculate as to whether "Einstein's universal speed limit" can be broken - and if perhaps Einstein might have been wrong, that the speed of light may not be a universal constant all across the cosmos. All over the world, physicists are attempting to warp, bend, fold or distort space-time in an effort to go faster and faster - and in a universe where the nearest star is 25 trillion miles away, the need for speed is real if we're ever going to get "out there".moreless
The Universe. It's sheer size and mystery are mind-boggling even to the most seasoned Cosmologists. Quantum Physicists are trying to unlock it's greatest mysteries. Will they succeed? And will we gain a greater understanding of ourselves in the process?moreless
What happens when a blind eye is shown a picture? Does the mind still register the image? Are we all connected through a massive universal nervous system? Neuro-scientists take on the challenge of proving there really is a sixth sense.moreless
Is a fourth dimension possible? How about a fifth? What about several dimensions, invisible but all around us? Molecular Biologists may have the answer.
Is time merely another dimension, like the dimensions of distance and space which we're more familiar with? Is it woven into the fabric of the Universe or merely a dream state, an illusion created in our mind to help us organize and sequence events? Top physicists offer their fascinating takes on the mysteries of time.moreless
Recent groundbreaking cosmology and state of the art science suggests that the Universe is not infinite - rather it may have a finite size and a unique shape.
Recently, scientists realized that there may be five times as much "dark" matter in the Universe as there is "regular" matter. And we don't even yet know what dark matter is made of - except that it's not made up of atoms or anything else which we're familiar with. And far stranger than dark matter is a newly discovered force called dark energy - which may well be the ultimate determinator of our universe's destiny.moreless
We have found that there's more that we don't know about what makes up the Universe than there is that we do know - and, based on recent discoveries made with the help of the world's most powerful atom smasher, the Large Hadron Collider, our understanding of matter, and of reality itself, is on the verge of another seismic shift.moreless
Are we alone in the universe - or do aliens actually/certainly exist? If so, why haven't we met any yet - or have we? What would intelligent beings from elsewhere even look like? How would we communicate with them? Are we ready for "first contact" or should we remain safely hidden away until we are more advanced?moreless
How did the Universe come to create life as we know it? Random chance? Cosmic seeds? Alien manipulation? What is life? We find it everywhere here on Earth, will we find it elsewhere in the Universe as well?moreless
We currently believe that the Universe is 13.7 billion years old and that we can peer back to the very first moments of its creation. But what happened before? If the Universe was born, where did it come from? What happened before the beginning of time?moreless
Is it possible to break the speed of light? Einstein's Theory of Relativity claims that time travel is possible if you're going forward in time, but that in order to go back in time one would have to break the speed of light - which has seemed to be impossible. But newly discovered quantum effects are now opening up "impossible possibilities" - possibilities which could prove dangerous to the very fabric of space-time and even the universe itself.moreless
Nothing in the known universe is more powerful than black holes - not even light can escape them. As astronomers discover more and more and bigger and bigger black holes, the question becomes not only whether or not they are the eventual destiny of all matter, but whether or not three-dimensional space itself could be merely an illusion. Is our existence taking place within a two-dimensional hologram at the edge of an enormous black hole?moreless
Is our Universe the result of random chance - or did some higher power create it? Recent research is revealing that the forces governing our universe are so finely tuned that someone, or something, must have created or at least calibrated them. Could it be that we are nothing more than some alien gamester's ultimate SIM game?moreless
