A star can burn its hydrogen for millions or even billions of years. But when the party s over, black holes form in an instant. How long does it all take to happen.

You’re right next to a black hole that’s starting to form. In the J.J. Abrams Star Trek Universe, this ended up being a huge inconvenience for Spock as he tried to evade a ticked off lumpy forehead Romulan who’d made plenty of questionable life choices, drunk on Romulan ale and living above a tattoo parlor. So, if you were piloting Spock’s ship towards the singularity, do you have any hope of escaping before it gets to full power? Think quickly now. This not only has implications for science, but most importantly, for the entire Star Trek reboot! Or you know, we can just create a brand new timeline. Everybody’s doing it. Retcon, ftw. Most black holes come to be after a huge star explodes into a supernova. Usually, the force of gravity in a huge star is balanced by its radiation - the engine inside that sends out energy into space. But when the star runs out of fuel to burn, gravity quickly takes over and the star collapses. But how quickly? Ready your warp engines and hope for the best. Here’s the bad news - there’s not much hope for Spock or his ship. A star’s collapse happens in an instant, and the star’s volume gets smaller and smaller. Your escape velocity - the energy you need to escape the star - will quickly exceed the speed of light. You could argue there’s a moment in time where you could escape. This isn t quite the spot to argue about Vulcan physiology, but I assume their reaction time is close to humans. It would happen faster than you could react, and you’d be boned. But look at the bright side - maybe you’d get to discover a whole new universe. Unless of course Black holes just kill you, and aren t sweet magical portals for you and your space dragon which you can name Spock, in honor of your Vulcan friend who couldn t outrun a black hole. Here we ve been talking about what happens if a black hole suddenly appears beside you. The good news is,supernovae can be predicted. Not very precisely, but astronomers can say which stars are nearing the end of their lives. Here’s an example. In the constellation Orion, Betelgeuse the bright star on the right shoulder, is expected to go supernova sometime in the next few hundred thousand years. That’s plenty of time to get out of the way. So: black holes are dangerous for your health, but at least there’s lots of time to move out of the way if one looks threatening. Just don’t go exploring too close! If you were to fall through a black hole, what do you think would happen? Naw just kidding, we all know you’d die.

Oasis of Peace: Amidst the chaos of the Israel Palestine conflict, a community based on hope has formed Subscribe to journeyman for daily current affairs and science: http://www.youtube.com/subscription_center?add_user=journeymanpictures For more on the Isreal Palestine conflict watch our playlist: https://www.youtube.com/playlist?list=PL0F3E4174CED2859C For downloads and more information visit: http://www.journeyman.tv/?lid=68006&bid=2 For years, the state of Israel and Palestine has been riddled with violence. But less than an hours drive from the heart of the conflict in Gaza, a Jewish-Arab community is working together for peace. With a seemingly endless stream of rocket attacks, bombing campaigns and revenge killings, the state of Israel and Palestine can often seem devoid of any hope of reconciliation. In the village of Neve Shalom/What-al-Salam however, Arabs and Jews are working together to create a world separate from the world of violence and chaos that surrounds them. "We live the model where we share the land, the power and the everyday life and administration, and this is our message" says Evi, a village resident. Children from both communities come from miles around to share an education in peace and mutual understanding at the local school-the only one of its kind in Israel in its pioneering approach of teaching Arabic and Hebrew lessons alongside each other. Families live along side each other and as Nadine and Tali testify, children, who would otherwise most likely be enemies, become best friends: "we grew up together and for high school classmates it was difficult to understand that this is our reality whereas for them it’s the first encounter". But as Tali s father, Cobi insists, the village is not a Utopia: "it s not that we will all think alike, it’s not that we are all the same, we are different and the issue is how to coexist in spite of the differences." But still the village exists in peace. And the example it sets has sparked the imagination of their fellow compatriots and the waiting list to live in the village is long. With the influx of new inhabitants questions about the peace they all cherish arise: "does community come first, or do we have to step outside and try to change things even when we know there’s little chance of success?"

One of the biggest mysteries in the Universe is the fact there there s matter, and not antimatter. Where did it all go?

For every type of matter from electrons, protons and quarks there is a similar type of matter known as antimatter. So why aren t there piles of antimatter rocks, cars and chocolate bars just lying around? Why does Scotty always have a little extra kicking around in his liquor cabinet? And where do I get mine? The primary difference between matter and antimatter is that they have opposite electric charge. Which seems pretty mundane. The negatively charged electron has an antiparticle known as the positron, which has a positive electric charge. Anti-protons have a negative charge, and are just flat out grumpy. We’ve been able to create these particles in the lab, and have even been able to create small amounts of anti-hydrogen consisting of a positron bound to an antiproton, when examined closely there’s were shown to have a goatee and a little colorful sash or dagger. When we create particles in accelerators such as the Large Hadron Collider, we seem to get equal amounts of matter and antimatter. This suggests that when particles were formed soon after the big bang, there should have been equal amounts of matter and antimatter. But the universe we observe is only made of matter, and… here’s the best part… we have no idea why. Why didn t the matter and antimatter completely annihilate each other? How come we ended up with a little more matter? This delightful mystery is known as baryon asymmetry. We do have a few ideas, and by we, I mean some giant brained crackerjacks have come up with a few plausible options. The most popular is that somehow antimatter behaves a little differently than matter. This could cause an imbalance between matter and antimatter. After particles collided in the early universe, there would still be matter left over, hence the matter we observe. Another idea is that the observable universe just happens to be in a region dominated by matter. Other parts of the multiverse could have observable universes dominated by antimatter. Baryon asymmetry is one of the big mysteries of modern cosmology. There is an even crazier idea. Antimatter might have anti-gravity. In other words, an atom of anti-hydrogen would fall up instead of down. If that is the case, then matter and antimatter would repel each other, and you might have matter universes and antimatter universes that are forever separate. There have been some initial experiments to test this idea, but so far there have been no conclusive results. What do you think? Where’s all our antimatter and how do we track it down?

But that was before a 2004 EU ban forced Malaysia s snake hunters underground. Pandian and his cousin Ganesan have been professional Python hunters for over 15 years, but they increasingly face a battle to make a living. "Before, we could catch ten a day", Pandian explains. "Now we just get one or two". Fears of extinction lead to the EU ban on Malaysian python skins. But it s proved ineffective and contraband skins still find their way to Europe. According to a CITES official, "they ve simply re-routed the trade from Singapore". There might yet be alternatives to hunting and a few enterprising Malaysians have opened up pioneering farms to save both the trade and the wild species. But is it too little too late for the python?
