[Q&A+]Smoking Gun Biosignatures, Dyson Spheres vs Warp Drives, Adopting the Metric System | Q&A 319

Heck yeah, fully metric! Except too much feet and inches here in Canada.

As we get more solar panels on earth and in space, given that space is bigger, what year would you estimate that our solar collecting in space will be bigger than (half the) earth?

I agree with “point lights down.” I read that sideways light pollution can be worse than upward, as it goes through more atmosphere and hits more particles etc. So you shade the top and sides, pointing down like Fraser says. Our local university now has a Dark Skies minor.

Fraser, did you continue your efforts to be able to read scientific Chinese papers?

"Belt Road Initiative". First time I hear of it. Had to look it up on wikipedia. Interesting. China is becoming what the US has been for the last few decades. I don't disagree.

Re: evidence for life. I know this isn't what you meant, but nothing could happen that "no one would question it." Some people don't believe the earth is round. :-0

Great episode, always weird realising that we indeed already begun the dysonswarm . Yeah lightpolution is Bad in my area, i think belgium used to be the "most-lit-country" because every highway had full lighting and Many streets too. Its a but better now but in my specific area the port/industry blocks the sky so hard i can only see about 100 stars in my sky.

I'm in the UK and we're mostly metric. We measure distance in miles and sell beer in pints but I think that's it. I'm 59 and was brought up using metric. I've had to retro-learn imperial to understand my parents. I still don't understand fahrenheight and can't estimate distance in miles.

The US going metric, how about pilots and mariners giving up knots?
