Synopsis
Hosted by Steve Nerlich. Dear Cheap Astronomy – Why do further way galaxies moving faster mean the Universe is expanding? It is all a lot to take in – not only is farther away stuff moving faster, also the Universe is expanding faster now than it was in the past and there’s standard candles and red-shift and much room for confusion. Dear Cheap Astronomy – Is there such a thing as a dead planet? To start with it’s probably unreasonably biocentric to define spherical objects that orbit the Sun and have cleared their orbits, as either alive or dead. We can redefine the question in terms of being geologically-active or not, but there it gets difficult to draw a line between what’s active and what isn’t.
