Gravitational Field Propulsion

[Marcel]

Here's a link to a paper I stumbled across. If I understand this correctly, it may be possible to create a linear repulsive gravitational field by spinning a torus of the proper mass at the proper velocity, and placing an extremely powerful electromagnet beneath it. It would fall up. Now picture placing a dome shaped cockpit above and what do you get? A freaking flying saucer!
Wondered what you folks think of this, 'cause it's mostly over my head.

Here is a quick summary - from what I gathered (It's over my head a bit too...)

He's basing his hypothesis on the fact that the Universe is expanding at ever increasing speed.

Traditional physics, particulary gravity, would dictate that as the universe aged the speed at which the universe expands would slow down due to the constant tug of gravity of all the matter in the universe.

What scientific observation has found is the opposite - the expansion of the universe is accelerating.

Many scientists theorise that there must be some misunderstood force contributing to the increased rate of growth of the universe. (Often referred to as Dark Energy)

Drocher and Hauser state that this force is a property of Gravity (essentially repulsive gravity, rather than attractive gravity, or antigravity) Based on th fact that all the other forces (Strong, Weak, Electromagnetic) have both an attractive, and repulsive component.

HPCC (Hauser is sitting at the applied university just 15 minutes away from my work place) is basing their papers on the Heim Quantum Theory (HQT), which is pretty insular in the scientific world (Burkhard Heim developed his theory alone because of a lab accident and published it only shortly before his death), but strangely have experimental data confirming their sometimes extravagant theories.

The HQT also has gravity as result of at least 4 different individual forces of gravity, which they base their calculations on.

For working with HQT, you need to know a mathematical feature behind it, which other physical theories don't have: Discrete differential operators. Instead of infinitesimal small numbers for a integration or differentiation, there is a minimum quantum unit for each mathematical operation.

This means, the same formula in HQT will behave pretty different to string theory or standard physics, who try to fit classic math around quantum physics.

The HPCC stuff is pretty nice and really fascinating, but while I would consider myself fan of it, I don't recommend reading their papers without some amount of skepticism. It is sometimes hard to see, where they start to leave information out or guess.

Sounds suspiciously like a Dean Drive ( http://en.wikipedia.org/wiki/Dean_drive ) or other magical thrust method.

I'll believe it when they have a working model.

One thing I noticed was the test data showed a minute change in gravity. With the amount of energy they threw at the experiment for such a small difference - what kind of energy density would be required to generate a usable gravity (antigravity) field for momentum?

AFAIR, they used already pretty optimistic magnetic field strengths in their propulsion system concepts. I remember something like 9 Tesla, the strongest we have produced is 26 Tesla (or 2,000 when allowing destruction of the magnet), but still...

Not to get off-topic, but this space music artist wrote an album as a tribute to Heim. I saw him perform it at the University of Pennsylvania a few months ago. Since you're talking about Heim, you know, I just thought you might like to hear this and all...

They will stop building them, when they started laughing again. :thumbup:
