Oh great ;-) So we can keep on looking for the magic placeholder material that matches unexplained gravitational effects until we have machines that can detect such low-levels--effectively not invalidatable. I think I prefer string theory at that point.
> the mass of ultralight bosonic dark matter must be more than 2 × 10^-21 electron volts (eV)
To put this in perspective, the current upper bound on the mass of a neutrino is around 0.1 eV, so 20 orders of magnitude higher.

Why does reality care about your aesthetic evaluation?
