Cheap Astronomy - Dear Cheap Astro #117: The Dark Side

Hosted by Steve Nerlich.


Stumbling around in the dark again.


What is the latest on dark matter?


Well, there’s not much new to report here. The nature and
composition of dark matter remains unknown, but the likelihood
that there is vast amount of non-interacting, invisible and
gravity-inducingly material remains high.


Are black holes the source of dark energy?


To give you the full story, someone sent a link to an article
that claims that black holes are the source of dark energy, along
with their actual question which was 'this is just bollocks isn't
it’?


And yes, it would seem so. Firstly, to properly unravel the
story, we should start by acknowledging that Cheap Astronomy
thinks the whole dark energy concept is a bit meh. But leave that
all to one side…
