Ok, folks, let's assume the mEMe Drive does NOT break the laws of Physics, and actually works.

What significance will it have for society, politics and economics on Earth, and in the Solar System?

What difference will it make for mankind over the next few hundred years?

>>55446305
Easier exploration perhaps, which could lead to finding aliens, or lack of them and fermi paradox depression.
>>
>>55446305

Potentially unlimited* acceleration, as long as it is powered even with a minimum charge (while in space).

Probably, using it to harvest asteroids for precious metals.

Potentially using it to get to the nearest solar systems in < 10 generations of humans.

It'll make space exploration a little easier. Once we get something up there, traditionally we've needed extra fuel to take it wherever. Now, we don't need the extra fuel, and we can actually accelerate for an indefinate amount of time. So we can reasonably fly anywhere

If it's for real, it'll make asteroid mining a possibility within our lifetime.

Although this institution has be be gotten rid of so society will have enough wealth to pay the bill.
>>
Bunch of dumb sh*ts in this thread. The acceleration is so slow (if it works), that a solar sail would be faster, cheaper and more reliable. Asteroids and star travel..... what a bunch of hooey.
>>
>>55446616
No. Remember that aside electricity it still requires inexpensive gasses in order to ionize and generate thrust.
>>
It's just one step into direction of space exploration and asteroid mining... however it brings even bigger problem with power generators.

Current power generators are RTGs that burn Pu-238 to produce electricity... And to have ~500W power source (not that much if you use it for propulsion) you'd need at least 1kg of Pu-238. (There's probably less than 30kg of usable Pu-238 in the world right now)

And solar power is useless after about 3Au from the sun... solar sail might go a bit further, but energy of the solar wind is losing strength as well...

So, until we also discover new ways of power generation, EM drive (if it works) is really limited...
>>
>>55448976
That is an ion drive, which it is not, because it requires no fuel.

How exactly do EM drives break the laws of physics?

Electromagnetic radiation is a form of energy after all.

well a new space race would be for sure.

>>55449429
Conservation of momentum. They generate thrust without expelling anything backwards somehow.
>>
>>55449429
>How exactly do EM drives break the laws of physics?
Well, that's the thing, even if it works, it doesn't break the laws of physics... it just breaks our understanding of them because it creates thrust without anything being thrown out the rear.

Essentially, it throws Newton's Third Law of motion out the window and pisses on it.

Intersteller space travel is worthless until we solve the problem with women. We can't let these walking parasites infect other star systems.

Em drive makes you able to travel to other planets within this solar system. The means to travel to other stars comes after we colonized mars.

Every "law" is an imperfect understanding, ever-refined. So hopefully this will lead to an improved theory, one way or another.

What's the point of actually making it work? As far as I understand the space isn't completely empty, there are stray asteroids and rocks that could damage any ship, and dust that will fuck with them in the long term. There's also cosmic rays and other kinds of radiation that are harmful to humans.

We still need at least 100 years of research to start with manned space exploration.

There's some theorizing that the thrust is produced by ablation of material from the inside of the engine. The microwaves are heating up and knocking off tiny particles of the very metal it's made of and kicking it out the back, producing thrust. We won't know for sure until someone throws the thing in a vacuum chamber with some really elaborate detectors; weighing of the engine before and after firing, even with some pretty sensitive scales and care to avoid even the settling / removal of dust, hasn't turned up discrepencies.

But there's also the possibility it's popping energy out of quantum interactions with space itself, which is far more exciting.

>>55450568
>stray asteroids
Asteroid belts aren't like the movies. There's a 1km rock over here, and then there's a 1km rock several hundred thousand miles over there on a "bad" day.
Micrometeorites aren't a huge problem once you get Whipple shields and self-healing materials involved. You could also evaporate them with lasers. There's no way to hide anything in space, so a sufficiently sophisticated detection and fire control system could be clearing the space in front of a ship with ease. "Dust" can be wiped off.
All this, on top of the fact that space is overwhelmingly empty.

Cosmic rays can be shielded against. Storing water and waste in the hull surrounding living and working quarters provides enough hydrogen-rich shielding. The far greater threat to extended duration space travel isn't radiation (especially as you get further from the sun or other radiatin-spewing celestial bodies), but the effects of micro- and zero gravity on the human body.

As for why we should do it, it's insurance against our annihilation and there's sweet shit out there we can snag for back home. Why go through the trouble of moving mountains for a paltry bit of platinum when you can wrangle a tiny space rock that has more of the shit than humans have ever mined + ever will mine in the next hundred years combined?
>>
>>55451217
/sci/, as with just about every new discovery or upcoming technology, is smart enough to know they should be skeptical, but not smart enough to know they should also be excited and considering possibilities other than "nope". Any time NASA has said DICK for the last few years, /sci/'s response has been "who cares". It's a homework help board more than anything.

They're either afraid of getting hurt or just want to show their intelligence by trying to rain on everyone's parade.

Not really.. Lunokhod used solar power.

However russians tested a bit different approach than RTG.

No clue how safe this is though... on the other hand Pu-238 RTGs were even used as cardiac pacemakers (some of them even run to this day inside of patients)

Some laws are more rigid than others, but there's a reason they're called laws and not approximations.

The principles of conservation and thermodynamics for example seem to have universal validity. These laws are hard and fast and are deeply connected to symmetries of nature.
>>
>>55446305
Well, it means satellites can station keep for as long as the parts work. That is - engine, solar panels, circuitry, etc.

That allows them to stay in orbit permanently, instead of only 5-15 years.

And it also allows them to be safely de-orbited without having to compromise on mass for extra 'de-orbit' fuel. Which in turn frees up space in orbit for newer and better satellites.

Would also allow for the first interstellar probes to be built.

Oh boy, bring on the technojesus memes. This drive wouldn't produce anywhere near enough thrust for that shit. You'd need maneuverability. This drive is only good for incremental acceleration over vast distances, and we already have drives that do that.

You people are all retards.

My thought is this: alright, you've accelerated it to a speed that's actually relevant in terms of the speed of light, like even something along the lines of .25c... You are nearing your destination; how the fuck do you slow down?
>>
>>55456319
turn it around and accelerate in the other direction?
>>
>>55448976

It's a completely fuelless drive. It (supposedly) generates thrust via microwaves alone. It doesn't use any fuel of any kind besides electricity.
>>
A bit easier to send probes to pluto.
>>
>>55456399
But then you have to apply the same amount of force over time (minus your desired entry speed). You'd have to start decelerating 60% into the trip to slow down from .25c to .001c

propellant, not fuel.

VERY important difference. Why?

For every action there is an equal but opposite reaction -- for rockets, you have to throw something in one direction to go the other direction. So, in your average rocket, you have to have huge amounts of propellant to just THROW OUT THE BACK LIKE TRASH to change velocity. And each pound of propellant costs some extra propellant just to move around. That's why rockets are so goddamned huge if they want to get anywhere.
