Spooky interview on death stars and dead comets on Halloween - ABC Breakfast News TV

Alan Duffy

A spooky interview as an object (fittingly a 'dead' comet) will flyby Earth on Halloween just further than the Moon's is from us. I spoke about the furthest galaxies from us that Hubble has found (using a high-tech martini glass) and a dead star that is tearing apart the planets in its solar system that will likely happen to use in five billion years time.

Kip Thorne on Interstellar Blackholes

Alan Duffy

One of the best science lectures I've ever seen was at Monash University by Caltech's legend GR expert Prof Kip Thorne giving the Einstein Centenary lecture to celebrate a century since General Relativity was released to the world. Fittingly, he used the examples of Interstellar's Black Holes, time dilation and 5-dimensional (bulk) beings to make the topic all the more accessible to the (sold out) auditorium.

Light from a mysterious star blocked - aliens? No.

Alan Duffy

My thoughts on a mysterious star that has its light blocked as something huge passes between us and this star. It could be a swarm of comets blocking the light as a nearby star flew by and disrupted comets in the Oort Cloud and sent them spiralling inwards. Another option is that it could be a Dyson Sphere, essentially the natural extension of solar panels in space that surround the star and block its light.

Gravitational waves remain elusive

Alan Duffy

Einstein predicted ripples in the very fabric of spacetime itself from violent collisions by massive objects like Black Holes. The latest search to find those ripples, or gravitational waves, have come up with only limits. Was Einstein wrong about these waves or is it our understanding of merging black holes? My thoughts in Cosmos Magazine.

"The accretion history of dark matter haloes - III. A physical model for the concentration-mass relation" Correa et al. (2015c)

Alan Duffy

My student's third paper of a stunning 3-part series on the growth of dark matter structures. In this paper Camila finally demonstrated the long studied concentration of dark matter haloes was tied to the growth history of that halo and hence, through her other works, the basic cosmology of the universe. Reference: Correa, Wyithe, Schaye and Duffy 2015 MNRAS 452, 1217C

Are We Alone? The $100m question

Alan Duffy

Are we alone? It's a fundamental question that haunts us as we look up into a cold, dark sky and (so far as we know!) the answer is yes, but perhaps for not too much longer. With $100m from the Breakthrough Listen project Australia will be leading the search for ET's signals. This is something that everyone is fascinated by, including politicians! Myself and a group of distinguished scientists gave a briefing at Parliament House to, amongst others, then Minister for Industry Ian Macfarlane and Minister for Science Karen Andrews (seen above with me politely trying not to be bored by my awful ramblings).

You can watch the interview at the National Library of Australia hosted by 666 ABC Canberra's Genevieve Jacobs, Nobel Laureate Prof Brian Schmidt, Prof Naomi McClure-Griffiths, Laureate Fellow Prof Matthew Bailes, Prof Paul Davies and yours truly (completely out of my depth!) 

You can also listen to the earlier news briefing arranged by AusSMC (Australian Science Media Centre)
