This “mind-wandering” describes a common phenomenon in which a wide range of self-generated thoughts emerge spontaneously.

Q&A: What’s Next for IceCube’s Hunt for ‘Ghost Particles?’

The IceCube Neutrino Observatory, or IceCube, is a massive cubic-kilometer detector embedded deep in the Antarctic ice at the South Pole that explores fundamental questions in physics and astronomy. For the first time since its inception in 2010, IceCube has just completed an upgrade consisting of adding over 600 new detectors to the existing 5,160 which were installed more than 15 years ago. This upgrade, along with the continued collaboration of Physics faculty and students from Drexel University, should lead to more information on neutrinos, or “ghost particles” as they are sometimes referred to, and pave the way for more cosmic discoveries.
