So, this is why the exotic matter has to be distributed over space-like distances i.e. it has to be distributed at superluminal speed.

but the space buble dosen't move at all in classic way v=0

oposit to what i stated

yes, seems "total bullshit"

thats the way to do science. It doesnt sound like something you understand, its bullshit.

this forum has a good lenghty discussion in the subject, including people OPPOSING it. It is serious research, so reading about it and opposing it with CALCULATIONS or physics is the way to do it, instead of just saying its bullshit. Most people on Talk Polywell know quite a bit of physics, so you should enjoy the argument, even if you side with the ones who argue against it. Paul March also posts there from time to time, and he works at NASA with Dr Sonny White.

Therefore is a good forum for you to say both Dr James Woodward and Dr Sonny White arguments are bullshit, and check the replies.

Dr James Woodward papers were already PEER REVIEWED btw, and his calculations were not opposed by phds in general relativity.

that just seems silly


considering that is where we discovered higgs bozon

[bitreaktor]

but i don't know much about physics

so i belive Dr. Richard Obousy and Dr. Eric W. Davis work as it seem to me quite reasonable

but i will chechk this white guy

butsonny is working on bran theory which you denied

they are not trying to find the Higgs Boson, so why would they need a particle accelerator?

there are PLENTY of important physics experiments in the world being run on simple looking devices as that, in important universities and elsewhere.

do not use the CERN as a comparasion.

CERN is about finding new particles using giant amounts of energy and WARP drive is something than needs both of that
i made assumption that you needed that complicated device just to find higgs boson and it is going to be much more harder to find exotic matter (ex.dark matter) and much more energy so they would need much more complicated devices even than cern to find it
and someone is suggesting you can find on a table size device from the other hand i heared they might have found something that might be to the dark matter (majorana or smth like this) in some nano created structures but again
this is niether gigantic nor hi tech nano and so
for me it is ridiculous like tesla crazy coil but i'm not phD
but also a lot of scientists are full of shit

but nothing to do with bending space time

THAT experiment is not trying to bend space time, but to cause very small fluctuations in the mass of piezoelectric materials. The experiment to bend space time is being done by Dr Sonny White at NASA, and they plan to bend it by something like a micrometer and will need an interferometer to measure it.

however, not only the experiment in the photo is NOT a warp drive, as you dont need huge amounts of energy to make very small 1 part in a million of a centimeter, bending of space time.

they dont want to create a warp drive at NASA. They want to test if they can bend space time. In MICRO amounts.

you would need huge amounts of energy to do a real warp drive to a ship, not to to make tests about the theory!

besides, the whole point of Dr Sonny White´s calculations is that the energy required is much smaller than what previously calculated as needed for the Alcubierre Drive... that decrease simply being a factor of different geometry and energy fluctuations. (like in lasers, where the laser energy fluctuates).

finally, the experiment in question is NOT (by orders of magnitude) strong enough to generate negative matter. It tries to create small FLUCTUATIONS in the mass of matter, tiny amounts. Negative matter is predicted as a consequence of Mach Theory, but to achieve it, yes, you would need experiments much more complex and energetic than a tabletop device.

i made assumption that you needed that complicated device just to find higgs boson and it is going to be much more harder to find exotic matter (ex.dark matter) and much more energy so they would need much more complicated devices even than cern to find it

wrong assumption, starting by the fact noone is trying to find dark matter. Exotic matter is a general term that applies to negative mass matter and other, but nobody knows if dark matter is negative mass matter or what, and as far as we know, dark matter may not even exist, for it is in fact just a filling of a gap.

[ramanujann]

What is Mach Theory? I've never heard about it and can't find nothing about it in google...

i mean the difference how it's actually works and the whole mythology behind it that it could revolutionize the world and send electricity wirelessly
great disconect between reality and expectations

y.

that is my point

even if they discover something there wont be WARP drive for at least 100 years

in a mean time we should concentrate on something that is totally doable and would revolutionize solar system travels :
Fusion drive means Mars in 1-or 2 days of travel or even less

Building a lunar base with 3D printing



Lunar base made with 3D printing.

(Phys.org)—Setting up a lunar base could be made much simpler by using a 3D printer to build it from local materials. Industrial partners including renowned architects Foster + Partners have joined with ESA to test the feasibility of 3D printing using lunar soil.

"Terrestrial 3D printing technology has produced entire structures," said Laurent Pambaguian, heading the project for ESA. "Our industrial team investigated if it could similarly be employed to build a lunar habitat." Foster + Partners devised a weight-bearing 'catenary' dome design with a cellular structured wall to shield against micrometeoroids and space radiation, incorporating a pressurised inflatable to shelter astronauts. A hollow closed-cell structure – reminiscent of bird bones – provides a good combination of strength and weight. The base's design was guided in turn by the properties of 3D-printed lunar soil, with a 1.5 tonne building block produced as a demonstration.



Multi-dome lunar base being constructed, based on the 3D printing concept. Once assembled, the inflated domes are covered with a layer of 3D-printed lunar regolith by robots to help protect the occupants against space radiation and micrometeoroids.

"3D printing offers a potential means of facilitating lunar settlement with reduced logistics from Earth," added Scott Hovland of ESA's human spaceflight team. "The new possibilities this work opens up can then be considered by international space agencies as part of the current development of a common exploration strategy." "As a practice, we are used to designing for extreme climates on Earth and exploiting the environmental benefits of using local, sustainable materials," remarked Xavier De Kestelier of Foster + Partners Specialist Modelling Group. "Our lunar habitation follows a similar logic."



The UK's Monolite supplied the D-Shape printer, with a mobile printing array of nozzles on a 6 m frame to spray a binding solution onto a sand-like building material. 3D 'printouts' are built up layer by layer – the company more typically uses its printer to create sculptures and is working on artificial coral reefs to help preserve beaches from energetic sea waves. "First, we needed to mix the simulated lunar material with magnesium oxide. This turns it into 'paper' we can print with," explained Monolite founder Enrico Dini.

"Then for our structural 'ink' we apply a binding salt which converts material to a stone-like solid. "Our current printer builds at a rate of around 2 m per hour, while our next-generation design should attain 3.5 m per hour, completing an entire building in a week." Italian space research firm Alta SpA worked with Pisa-based engineering university Scuola Superiore Sant'Anna on adapting 3D printing techniques to a Moon mission and ensuring process quality control. The effect of working in a vacuum was also assessed.



For ESA's 3D-printed lunar base concept, Foster+Partners devised a weight-bearing ‘catenary’ dome design with a cellular structured wall to shield against micrometeoroids and space radiation, incorporating a pressurised inflatable to shelter astronauts.

"The process is based on applying liquids but, of course, unprotected liquids boil away in vacuum," said Giovanni Cesaretti of Alta. "So we inserted the 3D printer nozzle beneath the regolith layer. We found small 2 mm-scale droplets stay trapped by capillary forces in the soil, meaning the printing process can indeed work in vacuum." Simulated lunar regolith is produced for scientific testing by specialist companies, typically sold by the kilogram. But the team required many tonnes for their work. "As another useful outcome, we discovered a European source of simulated lunar regolith," added Enrico. "Basaltic rock from one volcano in central Italy turns out to bear a 99.8% resemblance to lunar soil." "This project took place through ESA's General Studies Programme, used to look into new topics," Laurent commented. "We have confirmed the basic concept, and assembled a capable team for follow-on work." Factors such as controlling lunar dust – hazardous to breathe in – and thermal factors will require further study. 3D printing works best at room temperature but over much of the Moon temperatures vary enormously across days and nights lasting two weeks each. For potential settlement, the lunar poles offer the most moderate temperature range.

I wish I was born in 2030's

[Atmosphere]

Ah yes, the big question of every sci-fi fan/futurist. Was I born too early?

Our generation did/does see the rise of the computer, which is also a very important step in our development. But yeah, for real space exploration I think we are born to early.

only if we won't see radical life extension in our times
and it's almost not possible that it won't happen in next 30-50 years
i don't believe immortality will be possible but 150 years should be easily achievable in next few decades that gives me 130 years of life

that is my optimistic prediction
