Let There Be Light!

The binary system V404-Cygni 8,000 light years from earth is a microquasar that contains a black hole more than nine times the mass of our own sun. The best evidence of the existence of black holes comes from binary systems where visible stars orbit an unknown mass, and a recent find has shown V404-Cygni rapidly rotating and pulling gas from the nearby star and ejecting the spiralling plasma in different directions back out into space rather than straight along the axis.

It has been suggested that this new find could be applied to systems much larger than V404-Cygni and particularly how these black holes can affect time and space, especially when the ejected plasma reaches the speed of light that then channels into much larger regions of space. But, how can the governing gravitational and kinetic energy transfer – as seen similarly with astrophysical jets spewing out from the centre of galaxies -communicate the relativistic effects on physics at a large-scale?

Saolré: The Cycle of Life

As I prepare for my trip to beautiful, mythical Ireland in a few months, I am excited about visiting Newgrange (Gaelic sí an bhrú), which is a prehistoric 6,000 year old megalithic in County Meath. What is unique about this monument is that during the Winter Solstice, the sun rises over Boyne Valley and the beams of light strike into the passage chamber. It has been suggested that it was designed to observe solar and lunar cycles as well as that of Venus, but the attachment to astronomical and calendrical cycles with ancient mythological lore is clear, such as Aengus and Caer (I will be writing more about Irish myths and legends at a later date). What is more obvious is the understanding of the importance of cycles that exist in nature and our universe. Read More
