I mentioned Tuesday of this week that Francis Halzen won the Nobel Prize this year for work capturing neutrinos at the South Pole. Why does that matter? As background, consider that neutrinos (unlike, say, electrons) have no electric charge and virtually no mass. They are everywhere, passing quickly through us and anything else with little interaction. This justifies the nickname "ghost particles". They exist because supermassive black holes (and certain other bodies) create them and fling them out. Again: what do we learn from catching such a ghost in polar ice? We learn in what direction and how quickly it is moving when it hits the ice. Furthermore, whatever line it has been moving on when it did so, we know that it has been on precisely that line, without any swerving or bouncing about, for a looooooong time. Detect one, as Astronomy mag says in its treatment of the Nobel, and it points right back to its origin. Scientists will often b...
Continuing my train of thought from yesterday. (Please look back at yesterday's post before telling me this one makes no sense.) So: Suncor wants the Supreme Court of The United States to find that climate change policy must be federal policy, so Boulder has no business bringing a state law based suit against Suncor or ExxonMobil. That understood: how did arguments go? Chief Justice Roberts expressed skepticism about the preemption argument. He said it is not uncommon to base state law litigation on actions taken in whole or part in other states. He wanted to know: what makes this case special? Sarah Harris, the solicitor general for the US (here because the administration is taking Suncor's side) replied that if Boulder prevails it would ban the production of fossil fuels anywhere in the country. Roberts appeared unpersuaded. "That's a question of relief" to be raised in the context of the lawsuit if the lawsuit is allowed to proceed, not an argument agai...
