Why haven’t we encountered aliens yet? The answer could be climate change. Enrico Fermi, when asked about intelligent life on other planets, famously replied, “Where are they?”
Any civilisation advanced enough to undertake interstellar travel would, he argued, in a brief period of cosmic time, populate its entire galaxy. Yet, we haven’t made any contact with such life. This has become the famous "Fermi Paradox”. Various explanations for why we don’t see aliens have been proposed – perhaps interstellar travel is impossible or maybe civilisations are always self-destructive. But with every new discovery of a potentially habitable planet, the Fermi Paradox becomes increasingly mysterious. This impression is only reinforced by the recent discovery of a “Mega-Earth”, a rocky planet 17 times more massive than the Earth but with only a thin atmosphere. Finding ET So why don’t we see advanced civilisations swarming across the universe? The Earth has had 4 billion years of good weather despite our sun burning a lot more fuel than when Earth was formed.
Don’t Believe the Hype – 10 Persistent Cancer Myths Debunked. Google ‘cancer’ and you’ll be faced with millions of web pages. And the number of YouTube videos you find if you look up ‘cancer cure’ is similarly vast. The problem is that much of the information out there is at best inaccurate, or at worst dangerously misleading. There are plenty of evidence-based, easy to understand pages about cancer, but there are just as many, if not more, pages spreading myths. Live From The International Space Station! The International Space Station (ISS) is a habitable satellite that was launched on October 31 2000 and has had continued human occupation ever since, the longest on record.
It's an observatory and research laboratory in low Earth orbit with crew conducting experiments in Biology, Physics and Astronomy, amongst other things. The station orbits the Earth every 90 minutes, and in 2010 it had racked up almost 60,000 orbits, accruing a whopping 1.5 billion miles. To give you an idea of its size, in total it's about the area of a U.S. football field, and weighs over 400,000 kilograms. You can see the ISS without a telescope; the best time is the few hours after sunset or before sunrise. If you want to take a look at what it's doing and have a sneaky peek at the crew whilst they're on duty, check out the live ISS stream here! If the stream displays a black/blue screen, there has been a temporary loss of signal. La page de l'islam - La genèse de l'Univers et de la terre selon l'Islam. Ainsi, il semblerait que toute la création était à l'origine compressée en un élément unique, qui a éclaté pour donner naissance à l'Univers; cette notion est exprimée dans le verset suivant du Coran: "Ceux qui ont mécru, n'ont-ils pas vu que les cieux et la terre formaient une masse compacte ?
Ensuite Nous les avons séparés et fait de l'eau toute chose vivante. Ne croiront-ils donc pas ? " (Verset 30 / Sourate 21) Un autre verset du Coran laisse supposer que l'Univers, depuis sa création, en en perpétuelle expansion, et ses dimensions ne cessent de grandir.
