Have Mirror Planets Been Observed?
Over the last few years, several close orbiting (∼ 0.05 AU) large mass planets (M ∼ M Jupiter) of nearby stars have been discovered. Their existence has been inferred from tiny doppler shifts in the light from the star. We suggest that these planets may be made of mirror matter. We also suggest that some stars such as our sun may also have a similar amount of mirror matter, which has escaped de...
متن کاملHave mirror stars been observed ?
Observations by the MACHO collaboration suggest that a significant proportion of the galactic halo dark matter is in the form of compact objects with typical masses M ∼ 0.5M ⊙. One of the current mysteries is the nature and origin of these objects. We suggest that these objects are stars composed of mirror matter. This interpretation provides a plausible explanation for the inferred masses and ...
متن کاملHave mirror micrometeorites been detected ?
Slow-moving (v ∼ 15 km/s) ‘dark matter particles’ have allegedly been discovered in a recent experiment. We explore the possibility that these slow moving dark matter particles are small mirror matter dust particles originating from our solar system. Ways of further testing our hypothesis, including the possibility of observing these dust particles in cryogenic detectors such as NAUTILUS, are a...
متن کاملHave Orbitals Really Been Observed?
1492 Journal of Chemical Education • Vol. 77 No. 11 November 2000 • JChemEd.chem.wisc.edu The purpose of this article is to comment on the pedagogical ramifications of the recently claimed observation of d orbitals and the way in which these results were first announced and subsequently reported (1–6 ). Atomic orbitals—their use in writing electronic configurations and as a means of rationalizi...
متن کاملWhy have parasites promoting mating success been observed so rarely?
Host manipulation by sexually transmitted parasites which increases host mating rate and thus parasite transmission rate has long been viewed as a plausible parasite adaptation. However, empirical evidence for it is rare. Here, using an adaptive dynamics approach to evolution, we explore conditions under which such disease-induced mating enhancement is (or is not) likely to occur. We find that ...
