This is somewhat extended version of the talk given at the Gran Sasso Summer Institute: Massive Neutrinos in Physics and Astrophysics. It describes general ideas about mirror world, extra spatial dimensions and dinosaur extinction. Some suggestions are made how these seemingly different things can be related to each other.

SUPERNOVA EXPLOSIONS, 511 keV PHOTONS, GAMMA RAY BURSTS AND MIRROR MATTER
There are three astroparticle physics puzzles which fire the imagination: the origin of the "Great Positron Producer" in the galactic bulge, the nature of the gamma-ray bursts central engine and theExpand
MIRROR MATTER ADMIXTURES IN KS→γγ
The latest measurement of the KS→γγ branching ratio clearly shows an enhancement over the current theoretical prediction. As in other K and B meson decays, this invites to consider the possibility ofExpand
Evolutionary and structural properties of mirror star MACHOs
Abstract There can exist a hidden sector of the Universe in the form of parallel “mirror” world which has the same particle physics as the observable world and interacts with the latter onlyExpand
A mirror world explanation for the Pioneer spacecraft anomalies
Abstract We show that the anomalous acceleration of the Pioneer 10/11 spacecraft can be explained if there is some mirror gas or mirror dust in our solar system.
Mirror dark matter: Cosmology, galaxy structure and direct detection
A simple way to accommodate dark matter is to postulate the existence of a hidden sector. That is, a set of new particles and forces interacting with the known particles predominantly via gravity. InExpand
COSMOLOGY WITH MIRROR DARK MATTER
Mirror matter is a stable self-collisional dark matter candidate. If parity is a conserved unbroken symmetry of nature, there could exist a parallel hidden (mirror) sector of the universe composed ofExpand

Generalized mirror matter models
Abstract Non-minimal gauge models with exact unbroken improper space–time symmetries are constructed and their cosmological and astrophysical implications explored.
Dark matter detection in the light of recent experimental results
The existence of dark matter was suggested, using simple gravitational arguments, seventy years ago. Although we are now convinced that most of the mass in the Universe is indeed some nonluminousExpand
Mirror model for sterile neutrinos
Abstract Sterile neutrinos are studied as subdominant contribution to solar neutrino physics. The mirror-matter neutrinos are considered as sterile neutrinos. We use the symmetric mirror model withExpand

TeV scale quantum gravity and mirror supernovae as sources of gamma-ray bursts
Abstract Mirror matter models have been suggested recently as an explanation of neutrino puzzles and microlensing anomalies. We show that mirror supernovae can be a copious source of energetic gammaExpand
Gamma-ray Bursts Produced by Mirror Stars
I argue that cosmic Gamma-ray Bursts (GRB) may be produced by collapses or mergers of stars made of `mirror' matter. The mirror neutrinos (which are sterile for our matter) produced at these eventsExpand
Dark matter: the top of the iceberg?
We argue in favor of the existence of the LIPs, the least interacting particles, which would only interact with ordinary matter through gravitational field and could account for (at least) part ofExpand
The early mirror universe: inflation, baryogenesis, nucleosynthesis and dark matter
Abstract There can exist a parallel ‘mirror’ world which has the same particle physics as the observable world and couples the latter only gravitationally. The nucleosynthesis bounds demand that theExpand
Stabilization of submillimeter dimensions: The New guise of the hierarchy problem
A new framework for solving the hierarchy problem was recently proposed which does not rely on low energy supersymmetry or technicolor. The fundamental Planck mass is at TeV and the observed weaknessExpand
Matter-affected neutrino oscillations in ordinary and mirror stars and their implications for gamma-ray bursts
Abstract It has been proposed that the annihilation process ν ν →e − e + →γγ may be responsible for the generation of gamma-ray bursts (GRBs). The incipient neutrino–antineutrino pairs carryExpand
A quest for weak objects and for invisible stars
High quality spectra to be produced by SUBARU 8 meter telescope will be extremely valuable for numerous astronomical projects. Here I concentrate on two classical types of weak broad line objects --Expand
Deviations from the 1=r 2 Newton law due to extra dimensions
Abstract We systematically examine corrections to the gravitational inverse square law, which are due to compactified extra dimensions. We find the induced Yukawa-type potentials for which weExpand
Testing the nature of Kaluza-Klein excitations at future lepton colliders
With one extra dimension, current high precision electroweak data constrain the masses of the first Kaluza-Klein excitations of the Standard Model gauge fields to lie above $\simeq 4$ TeV. StatesExpand
Cosmic Gamma-ray Bursts. Lectures Presented at XXVII ITEP Winter School
The properties of the cosmic Gamma-ray Bursts (GRBs) are briefly summarized. A detailed bibliography is given with titles of the papers. Two fundamental theoretical problems are pointed out: theExpand
