A film about Dark Matter – Dr Tara Shears explains why scientists think that most of the mass in the universe is made up of something we can’t see and how a new experiment called the Large Hadron Collider might finally tell us exactly what this “Dark Matter” is.

What is a strangelet?: Strangelets are theorized cosmological objects composed of an exotic form of matter known as strange matter or quark matter. This form of matter is created in the cores of particularly massively neutron stars. In neutron stars, the remnants of collapsed stars with masses between 4 and 8 times that of our sun, pressure and temperature is so intense that the protons and electrons in atomic nuclei fuse to become neutrons. The resultant matter is sometimes referred to as neutronium, a sea of neutrons packed far more densely than conventional matter. Sometimes the pressure and gravity in the centres of neutron stars is so massive that the neutronium collapses into its constituent particles, quarks. This results in agglomerations of so-called strange quarks bound to each other directly much in the same manner that the transition from conventional star to neutron star results in seas of neutrons bound directly together. The names physicists have given this type of matter are “quark matter” or “strange matter”. This may be regarded as a phase change, like changing from a liquid to a solid, only at densities many orders of magnitude greater than those occuring in this solar system. It has been hypothesized that strangelets (sub-stellar agglomerations of strange matter) may be able to exist independently from the quark stars which created them. If so, there may be many strangelets in this universe, a possible explanation for the dark matter problem. Since …

Equal amounts of matter and antimatter were created at the birth of the universe but there’s very little of it around today. Dr Tara Shears explains why this is one of the greatest mysteries in science and how it might be solved by the biggest experiment in history. To learn more, visit www.labreporter.com

alltimetv.net Become my friend on MySpace CERN is conducting an underground launch on Wednesday the 10th of September 2008 of their Large Hardon Collider to see if it will be successful. Now they have moved the launch date of the full experiment to October 21st of 2008. That is next month! Hope all goes well, and trust me a probability is a probability, just like the atomic bomb. Good luck to us all! . http blackhole cern on earth chaos dooms day stupid scientists physics matter science

Please join us on Facebook for the latest science news and videos: tinyurl.com Cosmic Visions: New ESA Space Science Missions Move Forward. Under its Cosmic Vision initiative, the European Space Agency has selected three medium-sized science missions to enter the definition phase. Spacecraft to study dark energy, Earth-like exoplanets and our own Sun now have to prove that they can be built within the allocated budgets. 2011, just two of them will be retained to go forward for launches no earlier than 2017. This movie describes the three missions Euclid, Plato and Solar Orbiter. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com — Since the early ’60s, ESA has excelled in pushing back the frontiers in space science: exploring the nearest planets and the most distant celestial bodies of our solar system; lifting the veil with powerful telescopes on galaxy and star formation and probing the most violent processes in the Universe; and better understanding its evolution since the Big Bang. The three selected missions are the finalists from some 50 proposals which were whittled down to just six in late 2007 and submitted for industrial assessment. In February, the Agency’s Science Programme Committee pared down the choice once more. The project called Euclid will investigate key issues in physics, cosmology and general relativity. Until about 30 years ago astronomers thought the Universe was composed of ordinary …
