Edgar Nernberg est un militant crรฉationniste trรจs actif au Canada. Faisant preuve dโun enthousiasme sans failles afin dโimposer la thรฉorie de la ยซย Terre jeuneย ยป dans les รฉcoles, il fait รฉgalement partie du conseil dโadministration du premier musรฉe crรฉationniste canadien. Bref, Edgar Nernberg nโest pas ร proprement parler un ami des sciences. Et pourtant, lorsquโil trouve des fossiles de poissons dans son jardin alors quโil creuse une cave ร la pelleteuse, notre crรฉationniste nโenvoie pas pour autant un coup de godet rageur dedans.
"When Europe's Large Hadron Collider (LHC) started up in 2008, particle physicists would not have dreamt of asking for something bigger until they got their US$5-billion machine to work. But with the 2012 discovery of the Higgs boson, the LHC has fulfilled its original promise โ and physicists are beginning to get excited about designing a machine that might one day succeed it: the Very Large Hadron Collider. The giant machine would dwarf all of its predecessors (see 'Lord of the rings'). It would collide protons at energies around 100 TeV, compared with the planned 14TeV of the LHC at CERN, Europe's particle-physics lab near Geneva in Switzerland. And it would require a tunnel 80-100 kilometres around, compared with the LHC's 27-km circumference. For the past decade or so, there has been little research money available worldwide to develop the concept. But this summer, at the Snowmass meeting in Minneapolis, Minnesota โ where hundreds of particle physicists assembled to dream up machines for their field's long-term future โ the VLHC concept stood out as a favorite."
How life came about from inanimate sets of chemicals is still a mystery. While we may never be certain which chemicals existed on prebiotic Earth, we can study the biomolecules we have today to give us clues about what happened three billion years ago. Now scientists have used a set of these biomolecules to show one way in which life might have started.
