CERN Love » train. Sorry about all the silence the last couple weeks.
These days our day jobs are getting pretty busy. Beam dump at Point 6 After the question “what is 7 TeV?” Came up in the comments on our imminent collisions post I though it would be fun to take a tour of some common quantities in energy physics. All of this appears in other sources such as “LHC: The Guide” (2008) and, many talks such as “LHC Status and Commission Plans”. First of all, let’s stay humble. 27 km in circumference,100 m underground,8 stories high,12,500 tons, etc. But all this huge equipment is just support for the diminutive stars: bunches of 1011 protons,each 7 cm long and 1 mm in diameter (about the size of a mechanical pencil lead). That really isn’t much stuff considering that macroscopic things contain around 1023 atoms. So, what about this 7 TeV thing?
A TeV is actually a very tiny amount of energy. Science News – Science Articles and Current Events. Home. Current News on Space, Animals, Technology, Health, Environment, Culture and History. Science and Technology News, Science Articles. The 6 Most Mind-Blowing Things Ever Discovered in Space. It's actually really easy to think of space as boring.
The planets in our own solar system all seem to be empty rocks or balls of gas, and you find a whole lot of nothing before you get to the next star. Meanwhile, Hollywood's most creative minds can't get past populating the place with planets that look a whole lot like Earth (and specifically, parts of California) featuring monsters, rapey aliens or Muppets. But real space is far, far stranger. You just have to know where to look to find things like ... #6.
Science fiction writers have this annoying thing they do where they can only think of like five different types of planets. But scientists have studied almost 700 real planets outside the solar system, and some of them are downright gaudy. Via Inewp.comIt's a wedding gem worthy of Jesus or the Sultan of Dubai.
How Is This Even Possible? Via Spaceflightnow.comWhat a dick! Carbon is just a shitload of heat and pressure away from becoming a diamond. Photos.com"Yeah, that's cute. . #5. . #4. Monster Storm Rages on Tiny Misfit Star. A small, dim star appears to be wracked by a mega storm more violent than any weather yet seen on another world, astronomers announced.
The star, called a brown dwarf, is more massive than a giant planet but much lighter than most stars. Over a period of several hours, the star exhibited the largest brightness variations ever seen on a cool brown dwarf. "We found that our target's brightness changed by a whopping 30 percent in just under eight hours," graduate student Jacqueline Radigan of the University of Toronto said in a statement. "The best explanation is that brighter and darker patches of its atmosphere are coming into our view as the brown dwarf spins on its axis.
" [Illustration of the storm-wracked brown dwarf] Radigan will present a paper on the findings this week at the Extreme Solar Systems II conference in Jackson Hole, Wyoming. The researchers submitted their paper to the Astrophysical Journal. Home. Waiting For New Universes : 13.7: Cosmos And Culture. How long is long enough when it comes to waiting for a new cosmology?
How long will scientists, and everyone else, wait for an exciting but speculative theory to find some basis in experiment? Sean Carroll's new column in Discover Magazine recently made its debut with a wonderful piece on the multiverse (a longer explanation of the ideas also appears here). If you have never heard the term before, the multiverse is a universe of universes. It's the idea that beyond the universe we can see (via light that has been traveling towards us for the last 13.7 billion years), lie other entirely distinct "pocket universes," each with their own histories and even their own laws of physics.
The multiverse has become a popular topic in cosmological circles. Now don't get me wrong, I would love for the multiverse to exist. Outer Space Flight Videos & Pictures. Welcome to the Multiverse. Theoretical cosmologist isn’t one of the more hazardous occupations of the modern world.
The big risks include jet lag, caffeine overdose, and possibly carpal tunnel syndrome. It wasn’t always so. On February 17, 1600, Giordano Bruno, a mathematician and Dominican friar, was stripped naked and driven through the streets of Rome. Then he was tied to a stake in the Campo de’ Fiori and burned to death. The records of Bruno’s long prosecution by the Inquisition have been lost, but one of his major heresies was cosmological. These days, cosmologists like me may be safer, but our ideas have grown only more radical. Also like Bruno, cosmologists are reaching far beyond what observational evidence can tell them. The extent of what astronomers can see is frustratingly limited by the speed of light: one light-year (about six trillion miles) per year.
