Sinal astrofísico faz o que o LHC não pode: restringir a gravidade quântica e a teoria das cordas

Photons always propagate at the speed of light and obey the same rules of nature, regardless of... [+] their energy. If certain models of quantum gravity or string theory are correct, photons above a certain energy threshold should decay as they propagate through the Universe. The HAWC collaboration just tested this, and found that no…

Uma nova maneira de ajustar materiais exóticos: fino, elástico e grampo

Researchers from SLAC National Accelerator Laboratory and Stanford University made a super-thin, flexible membrane from a normally brittle oxide by growing it on a surface coated with a compound that dissolves in water.
