Evidence of WIMPs, Higgs bosons, supersymmetry, gravitons?????
A rather dark perspective, but I do see your point.Axel wrote:The visual impact of this photo is fantastic, combining the eeriness of Piranesi's Carceri with the sharp, symmetrical perspective of some modern action comics.
Interesting how often the 'thought' of space aliens pervades our culture today... of course this 'outer alien' (sometimes referred to as Gods) 'imagining' goes back to ancient times as is indicated by some of our ancestor's artistic and engineering habits.DavidLeodis wrote:I was intrigued by the following text in the explanation to the APOD:- "...the Large Hadron Collider (LHC), the most powerful particle accelerator yet created by humans".

) in this thread about particle accelerators. I mean, really, who thinks about particle accelerators??? Ask anyone on the street... What is a particle accelerator? and if you don't get an 'I don't know', you will likely get something like 350Z or MX2050. But ask that same person about 'space aliens' and you are apt to get a dissertation on the comings and goings from the planet Zorbo (that no one else knows about)... http://www.pbs.org/wgbh/aso/databank/en ... p31cy.htmlemc wrote:Larger accelerators have historically revealed more information… I can't help but wonder what an 'earth sized' accelerator would uncover???

The March 2008 National Geographic article where the picture appeared is a good place to start.Indigo_Sunrise wrote:Anyone subscribe to the "National Geographic" Magazine? This same image is featured in their March issue, in the story on the particle accelerator in France. I haven't finished reading it yet, but so far it's interesting.
Thanks very much for the link!!! What a well written and interesting article...bystander wrote: The March 2008 National Geographic article where the picture appeared is a good place to start.

Indeed. The "temperatures" generated by collisions are similar to those expected to be present something like a few microseconds after the big bang went boom. Among the questions they try to answer by smashing things together at high energies are how the first particles formed and why there appears to be an imbalance of matter and anti-matter.emc wrote:I was hoping to get some comments/discussion regarding the implications of cosmology from particle accelerators.

Powerful particle accelerators may be a natural phenomenon somewhere in space, but they aren't useful for us trying to detect new particles here on Earth, so we humans create a 'small' (=smaller than star-size) particle accelerator that we can control. That is, we hope to be able to control it.DavidLeodis wrote:I was intrigued by the following text in the explanation to the APOD:- "...the Large Hadron Collider (LHC), the most powerful particle accelerator yet created by humans".

research has been advancing our technical/social environment since the first cyclotron (thanks neufer). The LHC is exciting for its potential to uncover even more hidden information. The fact that science has been developing a relationship between stars and accelerated subatomic particles on our planet is so fascinating... my imagination reels.I very much like the way you wrote about star travel so matter-of-factly... very encouraging! ...Where's my galaxy cruiser "after-light" switch???starnut wrote:One thing I hope that discoveries from the LHC and other future particle colliders will lead is better understanding how the gravitational force is created. Until we learn if this fundamental force can be controlled by some artificial means, long-term space travel will remain very difficult to attain. We need to find a way to neutralize the gravitational force around a spacecraft on a planet or moon so it can lift off the surface without so much energy and to create artificial gravity inside the spacecraft for people on long space travels. Otherwise, long space voyages will remain just a pipe dream.
...maybe it should be called "after-gravity" switch! ...what a load that would be off my mind! In nature high energy cosmic rays daily collide with the earth at far greater energies than the LHC will achieve. Unfortunately, it's not enough to merely have an event...it takes a really complex instrument to study it.Case wrote:Powerful particle accelerators may be a natural phenomenon somewhere in space, but they aren't useful for us trying to detect new particles here on Earth, so we humans create a 'small' (=smaller than star-size) particle accelerator that we can control.
