Evidence layer

Claim by claim

The source study was found, but the study's evidence could not be profiled, so these claims couldn't be checked.

Claim 1 of 5Not checkedA paper being released by Physical Review D provides what might be a potential explanation for the discrepancy: flavor-changing neutrinos.View evidenceHide evidence

As statedpotential explanation

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 2 of 5Not checkedNeutrinos play a key role in current models of supernovae, and those models do not take into account neutrinos’ ability to change identity.View evidenceHide evidence

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 3 of 5Not checkedObserved supernova statistics may indicate that the core-collapse model is seriously incomplete, with a mismatch between star formation rates and observed supernova frequency.View evidenceHide evidence

As stateda much higher frequency of supernovae than we actually observe

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 4 of 5Not checkedIn progenitor-star studies, too few red supergiants have been identified as supernova progenitors, which may contribute to the discrepancy.View evidenceHide evidence

As statedtoo few red supergiants

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 5 of 5Not checkedGravitational-wave observations of black-hole mergers suggest a mass gap in black-hole formation, although the conditions for when a neutron star becomes a black hole remain uncertain.View evidenceHide evidence

As stateda ‘mass gap’ in black hole formation

Not checked

The source study was found, but this claim couldn't be checked against it.
