How Stars Die, Anti-gravity, Doughnuts and Dumbbells.

I’m going to put this here. It go buried so damn fast on Facebook.  – ( Beep boop boop ) –

LET THE RECORD SHOW that I single-handedly came up with a hypothesis by which we might confirm one of the concepts of Burkhard Heim and also know how to witness natural anti-gravity at work in the universe; or as I prefer to think of it: ‘Invert Gravity’.

The concept occurred to me while reading the lead article in a New Scientist magazine about ten years ago. After reading about the recent interest in the theories of Herr Heim, I came upon a shorter piece about our collective and continuing puzzlement over what exactly propels matter out of a collapsing star. Scientists at the time couldn’t find enough horsepower in any of their pet theories. I don’t know if that has significantly changed.

Supernova: “a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.” I won’t go into the complex taxonomy of the types; suffice to say that anything bigger than about 10 solar masses will eventually blow.

Wikipedia:The extremely luminous burst of radiation expels much or all of a star’s material at a velocity of up to 30,000 km/s (10% of the speed of light), driving a shock wave into the surrounding interstellar medium‘.

That’s a lot of horsepower, people, but 10 years ago no-one could explain it. Nor could they explain why the stuff goes north and south as huge ‘dumbbells’ of high-energy star stuff. (There are many beautiful photos on the internets. Here’s one:)

Supernova

Back to Heim – he proposed that if we could build a big enough torus, packed with super-magnets that we spin up to an enormous rotational speed … VOILA: Gravity would be neutralised or even reversed, and the thing would start to hover. Or fly. Or something.

So I was left thinking: ‘Hmm… super magnets … spinning torus … So how exactly does a red giant collapse in upon itself? What are the moment-by-moment dynamics?

Over many hours or days I imagined the bloated Red Giant slowly shrinking inwards. But of course it always had spin and as we all know: Angular Momentum is Conserved. (Tie a weight on the end of a string and spin around with it at neck height. Suddenly stand still. You’ll soon be strangling on the concept.) The equatorial regions with the most angular momentum would speed up as they neared the core, hold position longer, and resist the collapse (think orbiting satellites), while the polar regions would collapse fastest.

At some point the star would briefly look like a flattened ball, and that outer rim – made of screaming hot plasma – could conceivably take its own adventure for a short time. Seething with immense magnetic currents it separates into a plasma doughnut about the width of Mercury’s orbit and maybe as fat as Jupiter. (Okay: some wild guessing here.)

Pulled inward, orbiting at ever higher speeds, our plasma torus could conceivably shrink down to a tight tube, bound by those speculative magnetic fields (After all, plasma can act as a mega-electrical current (think lightning). Maybe now it is a miniscule 20,000 miles thick with a doughnut hole about the diameter of our sun.

We’re now just milliseconds away from the kablooie-moment (sorry about the science-y jargon), faster, tighter … until at some key moment that torus perfectly replicates Heim’s proposed machine, but at a HUGE scale. … And then what?

If Heim (and Ged Maybury) are right, it acts as an epic-sized ‘gravity inverter’; blowing off mega-tonnes of star-stuff north & south (that “equal & opposite force” thing). Imagine if we reverse the polarity of the graviton flow (you heard that in Dr Who’s voice, didn’t you?) and 90% of the star’s mass is ‘blown away’ to become a dumbbell shape of supercharged particles flying away at a tenth of the speed of light.

Imagine the gravitational forces inside a star that has already shrunk smaller than our sun. Reversing that for –x– seconds would give things a decent kick, eh? Maybe the only thing left after that is the ‘doughnut’, which subsequently collapses into a tiny neutron star or gets eaten by Homer Simpson. After that the cosmic light-show is over.

Now remember: it’s not an explosion. There was nothing inside the star with enough physical or chemical energy to push the stuff away. It is merely a momentary inversion of the normal action of gravity. Well: an extreme case of said hypothetical inversion.

Wild guessing, or worth crunching some numbers?

The quickest test would be to get good data on the ejecta from a supernova, calculate its collective mass/velocity/temperature (its energy, effectively), run it backwards accounting for radiant losses, and see if that matches the thermal and gravitational energy it theoretically had during the collapse of its parent star. That bit will be easy. Running simulations on a collapsing star, especially of the magnet behaviour of my theoretical torus – that’s gonna take a few super computers. Anyone up to it?

 

They say that gravity sucks, but maybe sometimes it blows. Something has to explain how stars explode exactly the way they do.

Anyway, since I got fobbed off* all those years ago, I’m putting it here on record for the rest of the world to ignore if it so deserves. But could someone do the math first, please? And you never know – somewhere in the near-future you might just get the chance to say, “Hey, I knew the guy who first thought of this!” Do that for me, okay?

Thanks for following my explanation, and goodnight.

  1. Very interesting, and I’m glad you posted this here. I’m also glad you wrote it so clearly for those of us without an astrophysics background! Sadly, I think my lack of scientific knowledge is coming through again. I can follow most of what you say about the star spinning and collapsing as it does so into a disk. But I don’t follow how that ends up reversing gravity, if only briefly. To me it seems like “the star collapses, then some magic happens and gravity is reversed, blasting matter into into space”. Would you mind going into more detail on this process, or could you point me at a reference elsewhere?

    1. Sorry, it is a bit light on Heim and his theories. I tried to cover it with: “he proposed that if we could build something big enough, packed with super-magnets on a torus that we then spin up to enormous speed … VOILA: Gravity would be neutralised or even *reversed*, and the thing would start to hover.”

      Go here and read. It looks fairly digestible. Skip to “A New Kind of Engine” if you want to cut to the chase.
