I, for one, have always wanted to know…


Readers will know the Large Hadron Collider, the massive particle accelerator built to answer such questions as “Is there a ‘God Particle” (Higgs Boson)?”  The LHC accelerates two counter-rotating beams of protons to nearly the speed of light and then brings them into collision inside giant, cathedral-sized detectors that study the subatomic debris that comes flying outward.  The folks at CERN, who operate the LHC, hold the world’s record for the highest energies ever achieved: the collisions of more than 10 billion protons per bunch at a total energy of 2.36 trillion electron volts, or TeV, per collision.

But the LHC raises as many questions as it hopes to answer…

Who hasn’t wondered, for example, what happens if one puts one’s hand in front of the beam?  Happily (if not conclusively), the folks at Sixty Symbols have gathered some answers:

As we think hard about wearing gloves, we might recall that it was on this date in 1969 that a number of meteor fragments fell near Murchison, in Victoria, Australia.  Analysis of the fragments has identified over 14,000 compounds in the carbonaceous chondrite; almost 100 of them, different amino acids, only 19 of which are found on earth…  encouraging proponents of “panspermia”– the proposition that life on earth was “jump-started” when key ingredients in the primordial soup dropped in from the Heavens.
