    Thanks, Sidey, I will try to get it. There's book by Michael Talbot (RIP) also, just called Holographic Universe. He makes the work of people like David Bohm more accessible to dimbos like me. Bohm's 'Wholeness and the Implicate Order' is great but has a lot of maths!

    Then there's the theory about 11 dimensions. My brain hurts, doctor. I take Andrew's point about the 'entity'. Dawkins says any such being in the universe - no matter how great - would have evolved somehow and therefore cannot be the Creator. This is true but not the point. God cannot be 'a being' but should be thought of as 'being'. This means we cant visualise Her/him /It as a giant pulsating orb at the centre of the galaxy. But I always do because I am thick.

    Yeah, of course. Physics for me is such a complex subject and find dense books hard to absorb sometimes. Like you say, when done right in song explanations can be conveyed and as above in a fun kind of way.

    Students probably. The astrophysicist is Victer Federov and the girl depicting dark matter personified is Aimee Zambrana. From the Bronx in New York. https://www.youtube.com/watch?v=kCcyK8OcCiA Check this one out..

    Gravitational Waves confirmed today in an announcement from Washington.

    https://www.theguardian.com/science/...of-the-century

    This is another confirmation of the general rightness of Einstein's theory of Spacetime.

    “This is transformational,” said ProfAlberto Vecchio, of the University of Birmingham, and one of the researchers at Ligo. “This observation is truly incredible science and marks three milestones for physics: the direct detection of gravitational waves, the first detection of a binary black hole, and the most convincing evidence to date that nature’s black holes are the objects predicted by Einstein’s theory.”
    The scientists detected their epoch-making event using an instrument so sensitive it could detect a change in the distance between the solar system and the nearest star four light years away to the thickness of a human hair.
    Prof B S Sathyaprakash, from Cardiff University’s school of physics and astronomy, said: “The shock would have released more energy than the light from all the stars in the universe for that brief instant. The fusion of two black holes which created this event had been predicted but never observed.”
    The finding completed the scientific arc of prediction, discovery and confirmation: first they calculated what they should be able to detect, then decided what the evidence should look like, and then devised the experiment that clinched the matter. Which is why on Thursday scientists around the world were able to hail the announcement as yet another confirmation of their “standard model” of the cosmos, and the beginning of a new era of discovery.

    Astronomers have already exploited visible light, the infrared and ultraviolet, radio waves, x-rays and even gamma-rays in their attempt to understand the mechanics of stars, the evolution of the galaxies and the expansion of the universe from an initial big bang 13.8bn years ago.

    Star babes spotted emerging from Black Hole.

    Infant stars have been discovered inside raging streams of material spewed into space by a monstrous black hole, according to a new study.
    The rather resilient star babies were found in jets of material ejected into space by a monster black hole at the center of a galaxy 600 million light-years away from Earth. As is the case in many other galaxies, the incredible force of the black hole's gravity accelerates the gas and dust around it, before eventually funneling the material into two jets that flow in opposite directions away from the black hole.
    Inside one of those cosmic "fire hoses," researchers found a population of stars that is "less than a few tens of millions of years old," and most of which are being swept along in the outflow at a rapid clip, according to a statement from the European Southern Observatory, home to the Very Large Telescope (VLT) that made the observations possible. The jets appear to provide a rich environment for the stars to form in; the scientists found the stars appear to be brighter and hotter than stars that form in "less extreme" areas of the galaxy, according to the statement.
    The jet where the star formation was detected is coming from the center of one of two galaxies currently merging together, collectively known as IRAS F23128-5919. To detect the baby stars, the research team used the MUSE and X-shooter instruments on the VLT. The researchers initially made an indirect detection of the stars inside the thickly obscured jets. Later, they were able to directly observe the baby stars.
    "Astronomers have thought for a while that conditions within these outflows could be right for star formation, but no one has seen it actually happening, as it’s a very difficult observation," Roberto Maiolino, head of the team that made the discovery and a professor of experimental astrophysics at the University of Cambridge, said in the statement. "Our results are exciting because they show unambiguously that stars are being created inside these outflows."
    The fate of stars


    While the black hole jet apparently provides a fertile star-producing region, it may ultimately subject the stars to a turbulent fate.
    "The stars that form further out in the flow experience less deceleration and can even fly off out of the galaxy altogether," Helen Russell, a researcher at the Institute of Astronomy in Cambridge, said in the statement. But Russell said that stars forming closer to the galaxy's center "might slow down and even start heading back inwards."
    If cosmic jets are ejecting stars into space across the universe that could help explain how the region between galaxies becomes enriched with "heavy" elements, the statement said. Stars fuse light elements, like hydrogen and helium, into heavier elements, including carbon, nitrogen, oxygen and many others. The explosion of very massive stars can produce even more heavy elements. Once the ejected stars die, they could spew these heavy elements into the intergalactic medium.
    Stellar formation inside the flows is considerable — the new study finds that a star about 30 times the mass of the sun is formed in the flow about once per year.
    "This accounts for over a quarter of the total star formation in the entire merging galaxy system," according to the statement.
    That's a significant-enough contribution that the fate of these stars could help determine the shape of a massive galaxy, the statement said. Elliptical and spiral galaxies have different structures suggesting different formation processes, but both types are surrounded by a halo of stars. Studying stars formed inside black hole jets could help explain how those features form.
    "If star formation is really occurring in most galactic outflows, as some theories predict, then this would provide a completely new scenario for our understanding of galaxy evolution," Maiolino said in the statement.
    The new study appears today (March 27) in the journal Nature.

    Yea, a great piece of detective work. There are several highly techie articles on Arxchiv about it.

    Good one, my question about all this is the assumption that the laws of physics are universal. How or why do we assume that?

    If, as is referrred to in the video, there is another universe "on the other side of the black hole" so to speak, then does it have the same laws?
