Zak and Derek discuss the "controversial" value of Newton's gravitational constant G. They cover the history of its measurement and how the value (and confidence in that value) has changed over time.

Zak and Derek discuss the big question: why is the future different than the past? Why do we remember the past but not the future? Much the discussion comes from Sean Carroll’s book, “From Eternity to Here: The Quest for the Ultimate Theory of Time“The podcast lives at https://www.thehyperfine.com/ Join our listener community on Reddit: https://www.reddit.com/r/TheHyperfine/ Follow the show on Instagram @thehyperfine: https://www.instagram.com/thehyperfine/ Derek on Instagram (and Twitter) @liketortilla: https://www.instagram.com/liketortilla/ Zak on Twitter @phyzaks: https://twitter.com/phyzaks
