What we’ve realized since then is that it’s not flawed, but simply didn’t make sense until now (Moore’s law, 21cm application didn’t exist) T H E O M N I S C O P E R S

13 LSS 21cm tomography Our observable universe Last scattering surface
2019/2/17 Our observable universe LSS Last scattering surface 21cm tomography

14 Our observable universe
2019/2/17 Our observable universe LSS Spatial curvature: WMAP+SDSS: tot= 0.01 Planck: tot= 21cm: tot=0.0002 Mao, MT, McQuinn, Zahn & Zaldarriaga 2008 21cm tomography

15 Our observable universe
2019/2/17 Our observable universe LSS Spectral index running: Planck:  =0.005 21cm = 2-potential: 0.0007 4-potential: 0.008 Mao, MT, McQuinn, Zahn & Zaldarriaga 2008 21cm tomography

16 Our observable universe
Neutrino mass: WMAP+SDSS: m <0.3 eV +LyF: m <0.17 eV Oscillations m>0.04 eV Future lensing: m~0.03 eV 21cm: m=0.007 eV 2019/2/17 Our observable universe LSS Final punchline: we’ll be talking lots at this meeting about fascinating physics we’ve learned from current cosmology data. But let’s not become complacent and lose sight of small a fraction of our universe we’ve mapped, and how much better we can do if we map the rest.
