Observations and computer models are now pointing to an explanation that would have seemed outlandish 30 years ago: most red giants have a much smaller companion star hiding in their gravitational embrace. This second star shapes the transformation into a planetary nebula, much as a potter shapes a vessel on a potter's wheel.
Until the Hubble Space Telescope launched in 1990, "we were pretty sure we were on the right track" toward understanding the process, says Bruce Balick, an astronomer at the University of Washington. Then he and his colleague Adam Frank, of the University of Rochester in New York, were at a conference in Austria and saw Hubble's first photos of planetary nebulae. "We went out to get coffee, saw the pictures and we knew that the game had changed," Balick says.
Astronomers had assumed that red giants were spherically symmetrical, and a round star should produce a round planetary nebula. But that's not what Hubble saw – not even close. "It became obvious that many planetary nebulae have exotic axisymmetric structures," says Joel Kastner, an astronomer at the Rochester Institute of Technology. Hubble revealed fantastic lobes, wings and other structures that weren't round but were symmetric around the nebula's main axis, as if turned on that potter's wheel.
The other option was that most planetary nebulae are formed not by one star, but by a pair of stars – what Orsola De Marco, an astronomer at Macquarie University in Sydney, named the "binary hypothesis". In this scenario, the second star is much smaller and thousands of times fainter than the red giant, and it might be as far away as Jupiter is from the Sun. That would allow it to disrupt the red giant while being distant enough to not be swallowed up. (Other possibilities also exist, such as a dive-bombing orbit in which the second star would approach the red giant every few hundred years, peeling off layers from it.)
The binary hypothesis accounts very well for the first stage of metamorphosis of a dying star. As the companion pulls dust and gases away from the primary star, they do not immediately get sucked into the companion, but form a swirling disk of material known as an accretion disk in the orbital plane of the companion. That accretion disk is the potter's wheel. If the disk has a magnetic field, it will propel any charged gases out of the plane of the disk and toward the axis of rotation. But even without a magnetic field, the material in the disk impedes the outward flow of gases in the orbital plane, so the gas will take on a bilobed structure, with faster flow toward the poles. And that's just what Hubble saw in its images of planetary nebulae. "Why look for a really complicated explanation when a companion star explains it really well?" says De Marco.
Right to the end they faked it, look at the image below supposedly taken a few days before they announced the Queen officially "dead", Its the “Historic Moment” photo opportunity when new UK Prime Minister Liz Tress met the Queen. The Queen was supposed to be 5ft 4 inches tall , and Liz Truss is 5ft 7inches.Mansur wrote: ↑Sat Jun 11, 2022 9:39 pmThough it is a few seconds only in the video, the crowd outside the window, the fake enthusiastic crowd (more evidently CGI) seems to be the really important feature.kickstones wrote: ↑Thu Jun 09, 2022 8:30 am But PEOPLE has learned that the video was filmed in March at Windsor Castle, with Paddington added later by CGI techniques.

Now, it seems you Brits have a fake monarch (or a one playing herself as an actor, which would be still nastier I think) with her being faked to be dead 'or who knows', probably in a faked palace with an actor butler and fake enthusiastic subjects outside – but a real Paddington Bear.
A recurring thought: propaganda in general tends to focus mainly on women. They are the consumers who are most important.
Yup.
It is possible that these things could be planned in advance?Mansur wrote: ↑Sat Sep 10, 2022 2:33 pm On the sixth of September the new Prime Minister is inaugurated, on the eighth the Queen dies (the media announce that her death has been officially announced), today is the tenth and a host of ceremonies have already been performed, which normally take weeks or even months to plan. I don't think anyone believes that sort of thing. New king, new PM, new era. In any case, tomorrow is the 11th of September.
I couldn’t agree more.This paragraph is particularly telling…
I have a BSc in Biology and spent many years in IT jobs and I'm highly skeptical of this stuff being able to actually do anything realistic other than burn through a sh*t ton of money. AI is dramatically over-hyped, I believe this has been covered on the forum variously. Scientists don't know as much about DNA et al as they pretend. You should take anything to do with biotechnology with a very large grain of salt.Flabbergasted wrote: ↑Thu Sep 15, 2022 4:57 pm Unelected POTUS Biden just signed an executive order intended to advance biomanufacturing innovation, opening up the floodgates for genetic experimenting on humans.

I tend to find that the more I think know about a complex system the more I realize that I don't really understand what's going on and it simply raises more questions. So often I walked out of a biology lecture with my head spinning trying to imagine how a human body hung together and actually managed to work. It's beyond mind boggling when you get into the details. As for how human consciousness is a thing...
Indeed. It's both unsettling and refreshing when we become honest with ourselves about how little we actually know and how much of our reasoning that is based on assumptions that actually aren't well founded.kalliste wrote: ↑Fri Sep 23, 2022 1:33 am I tend to find that the more I think know about a complex system the more I realize that I don't really understand what's going on and it simply raises more questions.
