Title: Cheap Astronomy – Dear CA #100: Some Impossible Things Before Breakfast

Organization: Cheap Astronomy


Description: Cheap Astronomy once again establishes that we can’t travel faster than light and that we still don’t know why the Universe is expanding.

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.

Bio: Cheap Astronomy offers an educational website where you’re only as cheap as the telescope you’re looking through.
