Oh, growth needs to be faster than that, because our modern system of feeding people, replacing infrastructure, etc. is unsustainable. Efficiency buys you time, but growth is what's needed to create new ways of feeding people, building infrastructure, etc.

I guess there might not really be too much disagreement between our two positions. In the end my position is that sustainability needs to be kept in mind, as opposed to fully discarded as a thought, so that you can focus on growth "no matter what", which I consider dangerous and reckless, unless you own a small business that sells shoes or something, and your dream is to expand across the country. Your footprint isn't that great, so in this case growth doesn't matter so much. But say you're a billionaire who owns the world's 2nd largest shoe company, that's when "growth no matter what" becomes a danger.
I'm watching tonight's ep. He were just talking about the 'standard candle' type of supernova. My question is, how do they know that that type of supernova is always the same size?

What I always wondered is how they factored in redshift into those candles. IIRC, we found out about redshift and universal expansion after we started using those candles. I mean, it's an obvious objection, so I imagine it's been handled. I just don't see how to do it.
I assume the light curve can be used to identify it... Though there was more to read about it, so I might be giving an erroneous answer.
I just watched the final episode, and I must say that all in all, I really enjoyed the show! The cartoons were a little bit annoying at times, but most of them were good too. A great sequel to an awesome show!
The cartoons annoyed me more than a little, but it was interesting to learn some stuff I hadn't known about the history of various scientific discoveries.
