Neutrino Dark Matter

Of the 4 Types of Neutrinos existing, the right handed sterile neutrinos are now strong candidates for the missing mass solution to dark matter.
The guitar nebula fast rotation rate is a classic example of pulsars kick started thousands of kilometers per second into spin by sterile neutrinos from supernova explosions.

Experiments at Fermilab will be able to confirm whether the decay of sterile neutrinos were responsible for the ionisation of Hydrogen in creating the first stars.

Sub Trillionth Trillionth of a Second Cosmology

The Wilkinson Microwave Anisotropy Probe WMAP has refined the COBE data from the previous century, and given additional bounce to inflation theory.

So what provided the false vacuum energy during phase transition during the phase transition at inflation.

Was it the mysterious dark energy?

Ekpyrotic Universe

I remember studying advanced stellar structure under Professor Ian Roxburgh from QMW, especially one of those guest lecture visits by his academic grandfather Fred Hoyle(ie Hoyle was The PhD Supervisor of a professor who himself was The Phd Supervisor of my professor). Fred Hoyle's lecture was his celebrated yet controversial Steady State Theory as an alternative to the Big Bang Theory.

I wonder what he would have made of the Ekpyrotic Model of the Universe?

Are we in a 4 dimensional spacetime bounded by an infinitely sized dimension existing as a brane wall within an 11 dimensional universe(yes forget 26 dimensional bosonic string theory!). This could be the ekpyrotic model which is an alternative to big bang theory. How about a parallel universe bounded by its own brane wall that bounced against our universe's brane wall 14 billion years ago?

So what is the current issue with inflationary cosmology? How does one explain away that the radius of the universe at that inflationary time increased faster than the speed of light?

Mathematics though D-Brane theory (for Dirichlet boundary condition)states that we exist in 11 dimensions. We are already aware of 4 of them, the rest are either curled up into strings(via Professor Michael Green's String Theory, also from QMW ) which are vibrational modes of energy at the sub-planck scale 10-^34m or infinite as our bounded brane wall.

Galactic DNA

A higher order of stellar structure 80 light years long has just been discovered by NASA's Spitzer Space Telescope within our own galaxy 300 light years from our central supermassive black hole, in the form of magnetically confined twisted doublex helix structures of stars formed over the last 10000 years in relation to its rotation about the center of the black hole.

Furthermore it is receeding at roughly 1000 km per sec, running perpendicular to the black hole within magnetic field lines 1000 times stronger than those on earth.
