You're all kind of blowing this out of proportion. Yes, it's interesting that the EMDrive can break a law of physics, but I didn't see anything about FTL or a warp field.

They confirmed the entire drive works in a vacuum. Previously when it was not in a vacuum, it generated thrust and created a warp field. They observed that the drive works exactly as expected in a vacuum (at least from the previous tests, not from known laws of physics), so there's little reason to suspect the warp field effect won't be observed here as well.

They still need to have the photon path-reading device perform the same detection in the vacuum, which is coming in the next few weeks, but there's little reason to suspect the same results won't appear again.

Yes, I'd like to reserve my Millennium Falcon please.

I am not even going to pretend I understand this, so basically they have created a field where time is sped up, so anything moving through the field looks like it is moving faster when in actuality it is just experiencing time at a faster rate? Can it be used to age cheese and wine at a faster rate?

 

They have an electromagnetic propulsion drive that they tested in vacuum conditions and it defied what physics would lead you to believe, thrusting within vacuum without anything to explain how the hell its happening. Physics says it should not theoretically be possible, yet it happened.

 

Basically the idea is that this could be used to move things through space without the need for traditional propellant sources, getting things around easier and MUCH MUCH faster. Earth to Luna in four hours with a spaceship? Doable a few decades from now with the right resources put towards it.

 

So the EM Drive was tested under vacuum conditions and led to the discovery of propellant-less thrust force that is currently unexplained, now leaving people wondering, "HOW!?"

On that subject- how do I know you're even real Jimmy? Or anyone here for that matter? For all we know we could be a tree branch blowing in through the open window in a suburban house and the wind leads the branches to hit keys in such a way that we are lead to believe the tree is a human being with articulate thinking and well thought out posts.

What if you're the tree?

[LPPrince]

What if you're the tree?

 

Thats what I'm saying.

 

What if WE'RE ALL TREES!?

 

The EM Drive will bring us self-awareness

 

Or the God Particle

 

Or the God Particle in the EM Drive tested in vacuum

 

OH MY GOD PARTICLE

You need to accept the fact that the future is now and I will not let you take away my Millennium Falcon.

 

I can dream!

It is pretty much guaranteed to happen.

 

Once humanity reaches the point where space travel has become as regulated and easy as travel is today, some starship manufacturer is bound to purchase the rights to create a real life consumer version of the Millennium Falcon.

So what is the deal with the Warp Field?

True. Still, even assuming "worst case scenario," this is JUST an EM drive that defies all known laws of physics... the applications of a device that can provide more thrust than it consumes is an age-old dream. It's free, unlimited power if developed correctly. It's a solution to the vast majority of humanity's problems.

Mr. Joosten and Dr. White stated that “a one-way, non-decelerating trip to Alpha Centauri under a constant one milli-g acceleration” from an EM drive would result in an arrival speed of 9.4 percent the speed of light and result in a total transit time from Earth to Alpha Centauri of just 92 years. 

 

However, if the intentions of such a mission were to perform in-situ observations and experiments in the Alpha Centauri system, then deceleration would be needed.

This added component would result in a 130-year transit time from Earth to Alpha Centauri – which is still a significant improvement over the multi-thousand year timetable such a mission would take using current chemical propulsion technology.

The speeds discussed in the Alpha Centauri mission proposal are sufficiently low that relativity effects are negligible.

So what is the deal with the Warp Field?

 

A group at NASA’s Johnson Space Center has successfully tested an electromagnetic (EM) propulsion drive in a vacuum – a major breakthrough for a multi-year international effort comprising several competing research teams. Thrust measurements of the EM Drive defy classical physics’ expectations that such a closed (microwave) cavity should be unusable for space propulsion because of the law of conservation of momentum.
 
JUMPING AHEAD-
For the last three years, Dr. White’s team has been conducting experiments to find out whether it is possible to measure, with an interferometer, a distortion of spacetime produced by time-varying electromagnetic fields.
 
The ultimate goal is to find out whether it is possible for a spacecraft traveling at conventional speeds to achieve effective superluminal speed by contracting space in front of it and expanding space behind it.  The experimental results so far had been inconclusive.
 
During the first two weeks of April of this year,  NASA Eagleworks may have finally obtained conclusive results.  This time they used a short, cylindrical, aluminum resonant cavity excited at a natural frequency of 1.48 GHz with an input power of 30 Watts.
 
This is essentially a pill-box shaped EM Drive, with much higher electric-field intensity, aligned in the axial direction.  The interferometer’s laser light goes through small holes in the EM Drive.
 
Over 27,000 cycles of data (each 1.5 sec cycle energizing the system for 0.75 sec and de-energizing it for 0.75 sec) were averaged to obtain a power spectrum that revealed a signal frequency of 0.65 Hz with amplitude clearly above system noise.  Four additional tests were successfully conducted that demonstrated repeatability.
One possible explanation for the optical path length change is that it is due to refraction of the air.  The NASA team examined this possibility and concluded that it is not likely that the measured change is due to transient air heating because the experiment’s visibility threshold is forty times larger than the calculated effect from air considering atmospheric heating.
 
Encouraged by these results, NASA Eagleworks plans to next conduct these interferometer tests in a vacuum.

Hopefully this means a manned Mars mission in the near future.

Hopefully this means a manned Mars mission in the near future.

 

Far more ambitious applications for the EM Drive were presented by Dr. White and include crewed missions to Mars as well as to the outer planets.
 
Specifically, these two proposed missions (to Mars and the outer planets) would use a 2 MegaWatt Nuclear Electric Propulsion spacecraft equipped with an EM Drive with a thrust/powerInput of 0.4 Newton/kW.
 
With this design, a mission to Mars would result in a 70-day transit from Earth to the red planet, a 90-day stay at Mars, and then another 70-day return transit to Earth.

[Queen Skadi]

I take it you don't understand this stuff either LPPrince?

We have yet to do anything significant with Luna yet, focus on colonizing it first before they even attempt a mission to Mars.

 

Honestly why are Mars One so keen on setting up a colony on Mars when it hasn't even been tested on Luna? Gotta learn to crawl before you can walk, once we have a kicking Luna resort set up with blackjack and nightclubs then we can attempt Mars.

The Moon is boring quite frankly. It's a dead world.

 

Mars may have had life.  It might even still have life, in microbial form. And while rovers are fantastic, I don't think they've quite supplanted humans yet. That isn't to say that there shouldn't be any manned missions to the Moon, just that the prospect of a manned mission to Mars is much more exciting. I also don't think we should wait to explore worlds outside of our own moon until we've first colonized it, so long as we have the means. 

 

On that note I also think some of Jupiter and Saturn's moons are much more interesting than our own.

That would be because Mars One is a scam...

Hence the need for blackjack and nightclubs, GAWD it's like you haven't read a word ive said

 

But that being said I can't imagine Mars would be that much more exciting, sure they might find evidence of life or actual life but then again they might find a hidden alien research station under the surface of the moon, the question is is there any evidence to suggest that such a discovery is likely?

[Jehuty]

Tell you what. Find me and beat me and I'll allow it.

Mars is easier to terraform.

In fact, I don't know of a single plan to terraform the Moon, it probably can't be done. Mars on the other hand can probably be terraformed with present day technology. Economically unfeasible though.

There is a lot more likelihood of finding evidence of life, past or present, on Mars than of finding some hidden alien cache on the Moon. Mars once had rivers and seas, and may have had an ocean. It also had a thicker atmosphere and a global magnetic field, and might have been warmer than it is now. A lot of the conditions for life to develop may have been there.

 

By life of course I'm not referring to little green men. But maybe there was primitive life like there was on Earth a billion years ago.
