Just don't go getting in arguments about stuff that isn't Space pls. Thanks!

TrumpxClinton ships are just no
Is that Donald and Hillary, or... well almost any combo of (Malania/Ivanka/Barron/Junior/etc) x (Bill/Chelsea/Buddy/Socks/etc) fulfils the promise of a terrible punchline. Pick any pairing you want...



So, Space, eh...  Roundest astronomical object found? Slushy sea below Sputnick Planitia? Supermoon? Beagle 2 might actually still be working? Peggy Whitson? There'a got to be something spacey to talk about, now that I've crashed the mood...

(Ah, ninjaed about that.)

Well, NASA recently (last month, I believe) dumped a large amount of 3D models for public use.  Otherwise, the Chinese set a new national record for longest spaceflight at 32 days aboard Tiangong-2, landing today in Inner Mongolia.  While it's nowhere close to the duration of many Soviet Mir missions, it's a significant proof of their progress.  It'll also be the only manned mission to Tiangong-2 under current Chinese plans; everything else is going to be handled remotely (including tests of a fully-automated resupply/refueling craft).

NASA/Eagleworks just released an interesting paper on the EMdrive.

This time in a peer reviewed journal.

http://arc.aiaa.org/doi/10.2514/1.B36120

No anomalous thrusts on the null article, no significant indicators of evaporation of test article being the source of thrust.

Looks like some armchair physicists will get a steaming plate of crow.

I always liked Bohm, but it's disappointing that we're still discussing mN/kW.

Before it is scientifically sensible to experiment on improvements to design, it is important to establish empirical factuality of claimed effects.

This test article is not intended to be efficient. Only to demonstrate the effect reliably.
After the test article is replicated and tested in other labs, and subsequent findings are published, THEN research into improved cavity or driving system designs for improved thrust per watt figures are sensible research targets.

Patience grasshopper.

Still think it's gonna be an FTL neutrino situation. What are really the odds that we actually ran into the hole in physics with a practical macro phenomenon?

as much as explaining and truly understanding an Einstein Rosenberg bridge..

Yeah, the amusing bit here isn't whether it works well, but that it works at all. I guess now we should get actual research into why the hell this thing works.
It's probably extradimensional lag starting to affect the universe simulation.

Hmmm, they're trying to explain it as an analog of the Casimir effect, but the specific paper was paywalled.

I was partial to Bohm and de Broglie because of a kooky idea I had about trying to explain the effect of increasing mass as reducing the spread of the temporal portion of a pilot-wave type of interaction, as I was trying to work back from relativity to arrive at quantum mechanics. There are various problems there though, not least of which was the appearance that hidden-variables were disfavored in plausible explanations of reality.

Setting aside my kooky ideas though, assuming the theoretical explanation given is accurate that could be really exciting, like, we might end up discussing ways to arrange components based on this effect to produce a negative energy region without the requirement of handwavium exotic matter, and that leads to wormholes.

What effects do we get if we arrange a ring of these Q-thrusters?
What does reversing the orientation do, if anything?
If this isn't a quirk of the design itself, could we optimize it with metamaterials?
How does the effect vary when changing the size of the Q-thruster?
What is the smallest possible version which exhibits this effect?

The EM drive doesn't allow FTL, if it is a true violation it's a reactionless drive. The benefit of this is that it provides impulse at an extremely high efficiency and could be derived from just having solar collectors instead of carrying any form of propellant. While an utterly amazing, paradigm-shattering development, it would not change lightspeed or even manned flights.

The only benefit in that regard is learning that we have to burn our physics textbooks and start all over again, which might result in discovering different limits to lightspeed.
