Great Aussie group! Shame I'm not into there type of music or anything post '80's. My Son has told me I'm stuck in a time warp from '50's/60's music Here's an old Aussie rock n roll singer: One I actually went to school with, and who like me got sacked from the Altar boys union after being caught drinking the Altar wine.

Here is there first public TV appearance ever on Australian Bandstand in the year of 1963....

This was a joke told by the then Aussie PM, Bob Hawke in 1983 after we won "the never before lost", America's Cup for 12 mtr Yacht racing........ https://www.youtube.com/watch?v=H5awwRWLbGY

Here's some more "cavemen"style music from a long ago era......

And here's my favourite Greek Angel again, singing a beautiful number called "Only Time will tell"

Here's that Greek Angel again singing country.......

Here is an associated article...... https://phys.org/news/2017-12-fracking-earthquakesweighing-dangers-south-africa.html Fracking and earthquakes—weighing up the dangers in South Africa December 20, 2017 by Andrzej Kijko And Surina Esterhuyse, The Conversation, The Conversation The South African government is looking into fracking to reduce the country's huge reliance on coal for energy. Fracking involves pumping high pressured fluids into rock formations to release reserves of oil and gas. Estimates for gas deposits in the main Karoo region of South Africa range widely. A few studies have been done for government on the potential for shale gas in the country. These include a report on the technical readiness for a shale gas industry, a strategic environmental assessment on shale gas and a multi-authored academic book on hydraulic fracturing in the Karoo. Government must now integrate this information into policy and develop regulations for the fracking industry. Environmental groups and landowners are concerned about the negative environmental and the social impact of fracking. They say that it could have an impact on water quality and quantity, and could also cause habitat fragmentation and loss. They are also worried about possible increased seismicity associated with deep well waste water injection and fracking operations.

https://phys.org/news/2018-02-man-made-earthquake-fracking-895m-faults.html Man-made earthquake risk reduced if fracking is 895m from faults February 27, 2018, Durham University The risk of man-made earthquakes due to fracking is greatly reduced if high-pressure fluid injection used to crack underground rocks is 895m away from faults in the Earth's crust, according to new research.The recommendation, from the ReFINE (Researching Fracking) consortium, is based on published microseismic data from 109 fracking operations carried out predominantly in the USA.Read more at: https://phys.org/news/2018-02-man-made-earthquake-fracking-895m-faults.html#jCp ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: THE PAPER: https://link.springer.com/article/10.1007%2Fs40948-018-0081-y Abstract: Induced earthquakes and shallow groundwater contamination are two environmental concerns associated with the interaction between hydraulic fracturing (fracking) operations and geological faults. To reduce the risks of fault reactivation and faults acting as fluid conduits to groundwater resources, fluid injection needs to be carried out at sufficient distances away from faults. Westwood et al. (Geomechanics and geophysics for geo-energy and geo-resources, pp 1–13, 2017) suggest a maximum horizontal respect distance of 433 m to faults using numerical modelling, but its usefulness is limited by the model parameters. An alternative approach is to use microseismic data to infer the extent of fracture propagation and stress changes. Using published microseismic data from 109 fracking operations and analysis of variance, we find that the empirical risk of detecting microseismicity in shale beyond a horizontal distance of 433 m is 32% and beyond 895 m is 1%. The extent of fracture propagation and stress changes is likely a result of operational parameters, borehole orientation, local geological factors, and the regional stress state. We suggest a horizontal respect distance of 895 m between horizontal boreholes orientated perpendicular to the maximum horizontal stress direction and faults optimally orientated for failure under the regional stress state.

Am I allowed to make an observation here? OK, we have the good old USA, who have had their war of Independence and as a result their bill of rights and this second ammendment, allowing anyone to bear arms...1791 wasn't it? Just three years after Australia received its first European settlers in the form of convicts from old Mother England. So why can't this second ammendment formulated in 1791 be changed or scrapped to reflect changing conditions and values in the year 2018? Some observations of mine; The US has risen to be the so called "leader of the free world" since WWII. Australia as a relatively small nation, has fought many wars including both world wars, on the side of the US. Our people are fairly similar in many ways, yet Australia had no qualms about enforcing strict gun laws and implementing a gun buy back scheme, after our worst ever gun massacre in 1996....It worked and is still working with no one disadvantaged. We also implemented change in the mid sixties with regards to the metric system of measurement and money: That wasn't easy, particularly for the oldies, but again it all worked and worked well to no disadvantage to anyone. The US also failed to follow this new innovation: Why? I do remember them losing a Mars probe due to a mix up of imperial and metric data sent to the probe for orbital insertion. So, could one conclude that the US is just totally adverse to change? Do they as the leaders of the free world, see any sort of " reduction of status" in implementing change either as an example from other free world nations, or to any supposed shame in changing what was accepted in 1791? Or are they clinging to the macho wild west image, so often portrayed by Hollywood in film...the cowboy mentality shown in many western films, along with the gun fights, Indian massacres etc. Let me say that my own country has nothing to be proud of in that regard, and with relation to the indigenous people, but we are attempting to make amends and progress is obvious with our country's original inhabitants. My Son just got a new car, and guess what? It has no bloody cd player in it! I was mortified!! But he explained to me with the advent of MP players and other devices for holding music, the old cd is just out of date!!! In my opinion the bottom line is guns were made to kill...the less of them about, the better for all of society. And while we are only a small populated country of 25 million people, we implement change when it is needed. Perhaps, just perhaps, your politicians could learn from us down under.

And my welcome also! And congrats on the pregnancy...your Mrs actually. As an old bastard, I've been through it all and now have a grown up young man in IT, who looks after his aging dad and Mum, and is a joy to be still living at home!

A BH has what is known as a "Photon Sphere" that is a region where light/photons can actually orbit and exists at 1.5 Schwarzchild radius. eg: If you were at this position, and you shone a torch directly ahead, it would orbit and hit you on the back of the head! Stars that we see, and accretion disks actually orbit outside the photon sphere and matter is spiraled in towards the BH. For any body to maintain an orbit at 1.5 Schwarzchild radius, it must be travelling at "c" therefor any orbit within 1.5 Schwarzchild radius is impossible. A great site for knowledge, facts about BHs can be found at http://casa.colorado.edu/~ajsh/ The difference being of course is that we have evidence for the BB, and the evolution of space and time, (spacetime) from t+10-43 seconds. Plus then we are able to reasonably speculate before that 10-43 seconds, and show how it could be possible for the BB to arise from nothing...https://www.astrosociety.org/publication/a-universe-from-nothing/ or http://www.phys.hawaii.edu/~dumand/post/dumandexternal/1990/HDC-3-90.pdf The point is that the universe is here, and while the above links cover speculative elements as to how it arose, I find it far far more reasonable then any magical supernatural being that supposedly is eternal.

I recently found this old tune from 1955, and damn! now I can't stop humming and singing it... Rusty Draper - The Shifting, Whispering Sands I know we have heard it all before, but really, they don't make-em like this anymore!

Here is that adorable Greek Angel once again, sing a Spanish number "Granada' and a delightful Greek song...... And this French number called Perdoname

Agreed: I do though accept the scenario, that humanity, given the time, may well achieve all that the laws of physics and GR allows.

Most lovers of classical music would be familiar with the great voice of Luciano Pavarotti singing Nessun Dorma..... Listen to this rendition by Sarah Brightman......

The best book I have ever read and I recommend anyone with any interest in science should read it, is "The Making of the Atomic Bomb" by Richard Rhodes. Not so much about what the title says, but more a complete history of late 19th century, and 20th century physics, from Curie, Bequeral, Rhotegen and Rutherford, through to Mitner, Fermi, Szillard, Bohr and Einstein, up to the Manhatten project and the likes of Feynman and Oppenheimer and culminating of course in the dropping of Little Boy and Fat Man and a vivid account of the results. A truly inspirational read.

Apparently spacetime, the universe, stars, planets, us, are just a fortuitous hicup or fluctuation in the pre BB quantum foam.
