Cheap Astronomy - Dear CA Ep. 100: Some Impossible Things Before Breakfast

Oh, nothing… Dear Cheap Astronomy – Is there really no way to do FTL travel? Well, no – but there’s no harm going through the options again. - Just doing it. - Quantum stuff. - Send information. But, faster than light? Given photons can’t even manage it, it’s seems highly unlikely we’ll ever get spacecraft to do it. Dear Cheap Astronomy – Is cosmic expansion just the tail-end of early inflation? Cosmic expansion – that is, the ongoing expansion of the Universe – is something we can readily observe. Indeed, since the further our we look the further back in time we are looking, it’s apparent that varying rates of expansion has been going on since the cosmic microwave background was released.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
