The Manhunt For Raoul Moat | True Crime Story | Real Stories The summer of 2010 saw one of the biggest manhunts in modern British history as police attempted to track down Raoul Moat, who had gone on the run after shooting his former partner and her new boyfriend, then firing on police officer David Rathband. This documentary draws on the testimony of eyewitnesses, experts and those who knew him best to examine the chain of events that culminated in a six-hour stand-off in the Northumbrian countryside.

We know trips in space will take a long time. Can we go to sleep for the journey and then wake up when we arrive? Support us at: http://www.patreon.com/universetoday More stories at: http://www.universetoday.com/ Follow us on Twitter: @universetoday Like us on Facebook: https://www.facebook.com/universetoday Google+ - https://plus.google.com/+universetoday/ Instagram - http://instagram.com/universetoday Team: Fraser Cain - @fcain / frasercain@gmail.com Karla Thompson - @karlaii Chad Weber - weber.chad@gmail.com We’ve spent a few episodes on the Guide to Space talking about just how difficult it’s going to be to travel to other stars. Sending tiny unmanned probes across the vast gulfs between stars is still mostly science fiction. But to send humans on that journey? That’s just a level of technology beyond comprehension. For example, the nearest star is Proxima Centauri, located a mere 4.25 light years away. Just for comparison, the Voyager spacecraft, the most distant human objects ever built by humans, would need about 50,000 years to make that journey. I don’t know about you, but I don’t anticipate living 50,000 years. No, we’re going to want to make the journey more quickly. But the problem, of course, is that going more quickly requires more energy, new forms of propulsion we’ve only starting to dream up. And if you go too quickly, mere grains of dust floating through space become incredibly dangerous. Based on our current technology, it’s more likely that we’re going to have to take our time getting to another star. And if you’re going to go the slower route, you’ve got a couple of options. Create a generational ship, so that successive generations of humans are born, live out their lives, and then die during the hundreds or even thousands of year long journey to another star. Imagine you’re one of the people destined to live and die, never reaching your destination. Especially when you look out your window and watch a warp ship zip past with all those happy tourists headed to Proxima Centauri, who were start enough to wait for warp drives to be invented. No, you want to sleep for the journey to the nearest star, so that when you get there, it’s like no time passed. And even if warp drive did get invented while you were asleep, you didn’t have to see their smug tourist faces as they zipped past. Is human hibernation possible? Can we do it long enough to survive a long-duration spaceflight journey and wake up again on the other side? Before I get into this, we’re just going to have to assume that we never merge with our robot overlords, upload ourselves into the singularity, and effortlessly travel through space with our cybernetic bodies. For some reason, that whole singularity thing never worked out, or the robots went on strike and refused to do our space exploration for us any more. And so, the job of space travel fell to us, the fragile, 80-year lifespanned mammals. Exploring the worlds within the Solar System and out to other stars, spreading humanity into the cosmos. Come on, we know it’ll totally be the robots. But that’s not what the science fiction tells us, so let’s dig into it. We see animals, and especially mammals hibernating all the time in nature. In order to be able survive over a harsh winter, animals are capable of slowing their heart rate down to just a few beats a minute. They don’t need to eat or drink, surviving on their fat stores for months at a time until food returns. It’s not just bears and rodents that can do it, by the way, there are actually a couple of primates, including the fat-tailed dwarf lemur from Madagascar. That’s not too far away on the old family tree, so there might be hope for human hibernation after all. In fact, medicine is already playing around with human hibernation to improve people’s chances to survive heart attacks and strokes. The current state of this technology is really promising. They use a technique called therapeutic hypothermia, which lowers the temperature of a person by a few degrees. They can use ice packs or coolers, and doctors have even tried pumping a cooled saline solution through the circulatory system. With the lowered temperature, a human’s metabolism decreases and they fall unconscious into a torpor. But the trick is to not make them so unconscious that they die. It’s a fine line. The results have been pretty amazing. People have been kept in this torpor state for up to 14 days, going through multiple cycles. The therapeutic use of this torpor is still under research, and doctors are learning if it’s helpful for people with heart attacks, strokes or even the progression of diseases like cancer. They’re also trying to figure out if there are any downsides, but so far, there don’t seem to be any long-term problems with putting someone in this torpor state.

World s Most Dangerous Roads: Deadliest Journeys in Congo in 2009 Years of war have left Congo’s infrastructure in ruins. In a country with no airport, no viable rail system and where the roads are almost totally unusable, transporting goods has become a serious problem. We’ll follow Eugene and Domingo through their journey which will soon become a nightmare. Slippery or eroded roads are common and often truck get bogged down. Drivers and passengers have to find solutions to free the lorry. Digging holes, pushing the truck with a trunk or tow it, all ways are good. Sometimes the vehicle can stay stuck in the mud for several weeks. The risk is also the mechanical breakdown since the trucks are second-hand materials from Europe and are in really bad state. ▬▬▬▬▬▬▬▬▬ Subscribe Free Documentary Channel for free: https://bit.ly/2YJ4XzQ Join the club and become a Free Documentary Patron: https://www.patreon.com/freedocumentary Facebook: https://bit.ly/2QfRxbG Twitter: https://bit.ly/2QlwRiI ▬▬▬▬▬▬▬▬▬ #FreeDocumentary #Documentary #MostDangerousRoads ▬▬▬▬▬▬▬▬▬ Free Documentary is dedicated to bringing high-class documentaries to you on YouTube for free.

This is the second part of our exciting Mars special. Immerse yourself in the interesting world of the planet Mars. Mars counted from the Sun, is the fourth planet in the solar system and the Earth s outer neighbour. It is one of the Earth-like planets. Its diameter of just under 6800 kilometres is about half as large as that of Earth, and its volume is a good seventh of the Earth s volume. This makes Mars the second smallest planet in the solar system after Mercury, but it has a diverse geology and the highest volcanoes in the solar system. With an average distance of 228 million kilometres, it is about 1.5 times as far away from the Sun as the Earth. In this documentary you will see the most beautiful facets of the planet Mars. ---- This channel offers you full episodes of high quality documentaries.

Could We Have a Second Home on Mars? – Second Thought SUBSCRIBE HERE: http://bit.ly/2nFsvTS Planet Earth has been our home for millennia, but we now understand that the future of the human race cannot be guaranteed if we re all cramped on one planet. As we set our sights on the stars in search of a second home, we consider our celestial neighbor, Mars...would it be a good candidate for Earth 2.0?
