Death and serious injury from dark matter

Preventing death and serious injury from falling trees and branches

Of 128 outdoor education related deaths examined since 1960, 14 have been due to falling trees or branches. This article examines the grounds on which death or serious injury due to falling trees or branches can be regarded as an inherent risk in outdoor education, and the extent to which such incidents can be regarded as preventible. It compares alternative approaches to prevention, and draws ...

Death of Stellar Baryonic Dark Matter

The nature of the dark matter in the haloes of galaxies is one of the outstanding questions in astrophysics. All stellar candidates, until recently thought to be likely baryonic contributions to the Halo of our Galaxy, are shown to be ruled out. Faint stars and brown dwarfs are found to constitute only a few percent of the mass of the Galaxy. Stellar remnants, including white dwarfs and neutron...

Death of Stellar Baryonic Dark Matter Candidates

The nature of the dark matter in the Universe is one of the outstanding questions in astrophysics. In this talk, I address possible stellar baryonic contributions to the 50-90% of our Galaxy that is made of unknown dark matter. First I show that faint stars and brown dwarfs constitute only a few percent of the mass of the Galaxy. Next, I show that stellar remnants, including white dwarfs and ne...
