yet another game changer?

...... no ........

Oh, there's a lot more than this...

[spuggy]

When, in the late 1980s, the aerospace engineer Dr Ron Evans went to his bosses at BAE Systems and asked if they'd let him attempt some form of gravity control, they should probably have offered him a cup of tea and a lie down.

Google "Project Greenglow".

[sammyg2]

Wait, what was that? I think we actually moved.

Naw, it was just a breeze.

No, we actually moved a tiny, tiny bit. Quick, check the sensors.


Nope, they say it was BS, we didn't move.


Well I'm still optimistic that someday, after spending $millions in tax payer's money, we'll eventually prove that this theoretical process can produce thrust, even if it's so small it's nearly impossible to measure.

Yeah, we'll show em!

[Hawkeye's-911T]

Here is an interesting piece I cobbed from an article on the as yet to be verified or completely debunked process of 'cold fusion' & how it may apply to the subject matter of Doc's thread:

"Fifty years ago, Thomas Kuhn taught us that this is the usual way for science to deal with paradigm-threatening anomalies. The borders of dominant paradigms are often protected by reputation traps, which deter all but the most reckless or brilliant critics. If cold fusion, or low-energy nuclear reaction (LENR) were an ordinary piece of science (or proposed science), the challenge posed would promise fascinating spectator sport for philosophers and historians of science – a Kuhnian revolution waiting to happen, perhaps, with threats to the stability of the reputation trap now clearly in view. We could take our seats on the sidelines and wait to see whether walls fall – whether distinguished skeptics end up with egg on their faces. 'Pleasant is it to behold great encounters of warfare arrayed over the plains, with no part of yours in the peril,' as Lucretius put it."

Seems almost infinitely improbable.

[DanielDudley]

The infinite improbability drive is a wonderful new method of crossing interstellar distances in a mere nothingth of a second, without all that tedious mucking about in hyperspace. It was discovered by lucky chance, and then developed into a governable form of propulsion by the Galactic Government's research centre on Damogran. This concept was developed by Douglas Adams in the Hitchhiker's Guide to the Galaxy.


The principle of generating small amounts of finite improbability by simply hooking the logic circuits of a Bambleweeny 57 Sub-Meson Brain to an atomic vector plotter suspended in a strong Brownian Motion producer (say a nice hot cup of tea) were of course well understood — and such generators were often used to break the ice at parties by making all the molecules in the hostess's undergarments leap simultaneously one foot to the left, in accordance with the theory of indeterminacy.

Many respectable physicists said that they weren't going to stand for this, partly because it was a debasement of science, but mostly because they didn't get invited to those sorts of parties.

Another thing they couldn't stand was the perpetual failure they encountered while trying to construct a machine which could generate the infinite improbability field needed to flip a spaceship across the mind-paralyzing distances between the farthest stars, and at the end of the day they grumpily announced that such a machine was virtually impossible.

Then, one day, a student who had been left to sweep up after a particularly unsuccessful party found himself reasoning in this way: If, he thought to himself, such a machine is a virtual impossibility, it must have finite improbability. So all I have to do in order to make one is to work out how exactly improbable it is, feed that figure into the finite improbability generator, give it a fresh cup of really hot tea... and turn it on!

He did this and was rather startled when he managed to create the long sought after golden Infinite Improbability generator. He was even more startled when just after he was awarded the Galactic Institute's Prize for Extreme Cleverness he was lynched by a rampaging mob of respectable physicists who had realized that one thing they couldn't stand was a smart-arse.

As soon as the ship's drive reaches infinite Improbability, it passes through every conceivable point in every conceivable universe simultaneously.

I expect there will a gravitic drive, one of these days. There might even be a space-time bubble warp drive. The main issue is it will still have to work with the law of conservation of energy. You have to add energy as you move out of the gravity well. The energy has to come from somewhere.

[M.D. Holloway]

Just got to get to a stable atomic number of 139 and hit it with neutrinos, bends space time and you just ride the wake. I don't see what the issues are here folks. Come on, work with me!

As long as Zoe is my copilot I'm fine with that.

I'd prefer Trillian

Three is more analog and spectrally positive.
All possibilities are fruitful.

Anybody got a spare widget for an em-drive that I am restoring. The wizard that sold it to me, told me that every part was in the boxes that I bought. I really should should have seen it running before I transferred over the bitcoin.

[techman1]

Just a thought, please chime in and discredit, or just discuss.

What is black matter? In all the discussions, i do not see any way of measuring it, just theories.
Thought one: equal / opposite reaction. If black matter exists, can you push on it and get a reaction?

How do you push on something that is theoretically there, but not quantifiable?

Dark matter is unaccounted for mass in the universe for things to be doing what they are doing based on one of the theories. It's called "dark" because you can't see it.

[techman1]

Yep. Unaccounted mass. The train of thought is: What is the makeup of dark matter? Still not quantified?

Cave man probably looked at birds flight as amazing. They did not realize the bird was "Pushing" on air, cause they could not see it.

Earlier in the thread Scotty was quoted about physics. Not thinking about changing the laws, just pointing out, as an example, if you can't quantify black matter, how do you know the EM drive is not pushing against it?
