Where it stands

DisputedOne piece of evidence for, two against. It needs two reviews to be accepted.

What it predicts

  • Hydrogen sublimation proportional to sunlight reproduces the acceleration's fall-off with distance.
  • Hydrogen-ice bodies can form in the coldest molecular-cloud cores and survive to reach the Sun.

What would rule it out

  • A demonstration that a hydrogen-ice body of the required size cannot survive the travel time from any plausible birth site.
