Why is the cosmological constant so "wrong compared to theory"
No evidence for supersymmetry yet at 10^-17cm via LHC
No evidence for WIMPs
How do we combine QM + GR?
Do black holes destroy information? How to solve the BH firewall problem?
> Speculation
Is there supersymmetry at higher energies than the LHC can probe?
Is spacetime doomed? I.e. is space-time a hologram on the boundary or some other emergent phenomenon
Is there a multiverse?
Is decoherence a solution, or does the wave function "collapse", or simply many-worlds?
Is perturbation theory sensible or is there a deeper more elegant way to calculate scattering?
Is time emergent or fundamental?
