First Black Holes May Have Incubated in Giant, Starlike Cocoons
'The first large black holes in the universe likely formed and grew deep inside gigantic, starlike cocoons that smothered their powerful x-ray radiation and prevented surrounding gases from being blown away, says a new study led by the University of Colorado at Boulder.'
Dark power: Grand designs for interstellar travel
'No one disputes that building a ship powered by black holes or dark matter would be a formidable task. Yet remarkably there seems to be nothing in our present understanding of physics to prevent us from making either of them. What's more, Crane believes that feasibility studies like his touch on questions in cosmology that other research hasn't considered.'
Splitting Time from Space—New Quantum Theory Topples Einstein's Spacetime
'Was Newton right and Einstein wrong? It seems that unzipping the fabric of spacetime and harking back to 19th-century notions of time could lead to a theory of quantum gravity.'
NASA to develop haptic air-typing spacesuit gloves
'NASA is considering plans to integrate haptic vibro feedback and Halting State style
air-writing accelerometer capability into spacesuit gloves.'
(Why not just use chip-enhanced mindpower?)
