How did physicists even come up with this bizarre idea?

We expect the most fundamental machinery to have the fewest possible moving parts – or free parameters. This is why the standard model of particle physics is considered incomplete. Its equations predict many things with stunning accuracy, but they first require us to tune many mathematical knobs and dials. We need to use physical measurement to fix 19 free parameters like the masses of particles. And then there’s gravity, which doesn’t fit into the standard model at all. So surely there exists a deeper set of cogs and wheels – a theory that brings all observable phenomena into the same mechanical framework. That would be a theory of everything, and this is the great hope of string theory.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangJustin LloydAnton LifshitsCoolAsCatsDavid NicklasFabrice EapJuan BenetQuasarDean FuquaJames FlowersMark RosenthalRoman PinchukTambe BarsbayVinnie FalcoHypernovaChuck ZegarDan HarrisDonal BotkinEdmund FokschanerJohn HofmannJordan YoungJoseph SalomoneMartha HuntMatthew O’ConnorRatfeastThanks to our Patreon Gamma Ray Burst Supporters: Alexander RodriguezAlexey EromenkoBrandon CookBrandon LabonteDaniel LyonsDavid CraneFabian OlesenFauzan ArdhanaGreg AllenGreg WeissJack FroschJames HughesJJ BagnellJon FolksJoseph EmisonJosh ThomasKevin WarneMalte UblMark VasileNathan LenizNicholas RoseNick VirtueScott GossettShannan CatalanoShawn AzmanTommy Mogensenسلطان الخليفي Learn more about your ad choices.

The attention has been on Space-X and Blue Origin with their reusable rockets. But there’s one private space program that’s been doing things a little differently. Richard Branson’s Virgin Galactic isn’t building rockets at all – it’s building spaceships. And I got to sit down and talk to him about it.

And then, on February 22nd, the VSS Unity, reached space in a sub-orbital flight carrying the first-ever passenger-astronaut on a private spacecraft.
