"Lorentz symmetry might be broken but there doesn't really exist a glimpse of evidence or motivation why it should be broken. Such a breaking might be studied as a possibility, to some extent, but it would cause many problems, it would most likely return us philosophically before 1905, and the people who say that such a breaking is needed in quantum gravity are clearly wrong because string theory satisfies all the required properties of quantum gravity but it also respects the Lorentz invariance in flat space."

“According to polls, a majority opposes the radar base. But it's not necessarily the sensible part of the Czech population. The demonstrations against the base are usually organized by communists, Islamists, and "peaceful feminists" .”

“Your humble correspondent realizes that many readers are left-wing, anti-string-theory fighters. So they probably smoke marijuana and this is my modest attempt to help them.”

“Some extreme optimists argue that North Koreans won't know how to mount the bombs on their missiles. Maybe, they have completed the H-bomb but haven't invented the screwdrivers and ropes yet.”

“Greenpeace protesters who lived on the trees right above the planned radar location and who eat environmentally friendly roots, insect, excrements, and dirt.”

“You can't define whole disciplines of science to agree with random constraints that you invented. Instead, the purpose of disciplines of science is to decide whether your assumptions about the Cosmos and other things are correct. If there is a disagreement between the best theory and your assumptions, it's your assumptions that are wrong according to science.”

“I wonder how Feynman would feel if he had to be talking to not just a few nuts of this kind but e.g. to 2,500 similar nuts who would be moreover described by the media as good scientists, if not the best ones in the world. ;-) Good for him that he managed to die in time.”
