Your support is needed...
SpaceTime is an independently produced podcast (we are not funded by any government grants, big organisations or companies), and we’re working towards becoming a completely listener supported show...meaning we can do away with the commercials and sponsors. We figure the time can be much better spent on researching and producing stories for you, rather than having to chase sponsors to help us pay the bills.
That's where you come in....help us reach our first 1,000 subscribers...at that level the show becomes financially viable and bills can be paid without us breaking into a sweat every month. Every little bit helps...even if you could contribute just $1 per month. It all adds up.
By signing up and becoming a supporter at the $5 or more level, you get immediate access to over 280 commercial-free, double, and triple episode editions of SpaceTime plus extended interview bonus content. You also receive all new episodes on a Monday rather than having to wait the week out. Subscribe via Supercast (you get a month’s free trial to see if it’s really for you or not) ... and share in the rewards. Details at Supercast - https://bitesznetwork.supercast.tech/
