We are not going to the stars considering the distances involved. Mars, yes. Flybyes to Jupiter and Saturn. Probably. Neptune, Pluto (Yes, I’m old school), Uranus. No reason to go there. Satellites have done the job this year.

Venus - too hot. Mercury - Way to hot.

Moons around the planets. Some, yes. Some are dangerous.

This all assumes that mankind is still around in the near future. With No. Korea and Iran still unleashed, I’m not taking any bets.

Whether it works or not it won’t let us reach the stars. It might get us to Mars.

Well, it will let us reach the stars if it works, but not in an efficient time span.

Personally I don’t believe any human that will ever exist will feel the light of an alien star on their skin.

The way progress works, once we can cost-effectively mine the resources of the asteroid belt, it will create demand for technology to explore the Oort cometary region. Mastery of that stage will create technology for the next.

Thanks for posting. (In)credible science.

I’ve been following the EM drive for years and the only successful tests registered thrust below the margin for measurement error. It’s not real.

yep..as soon as the cost vs return maths work out, the world will change and fast. we are on the cusp of a change i think. we need the tech to remotely mine and return material at a price point that gives a return.

the new companies springing up will move space away from a govt run adventure to a profitable business. to be fair to the US government, the lack of funding to NASA has created these businesses. by dropping shuttles etc, they have created space for companies to thrive and push.

on the EM drive, at some point someone will build it and prove it works or doesnt. it seems kinda unbelievable to me but up until recently so was landing a rocket on a ship...

Reminds me of E-CAT from a few years back.

Agreed.

For a "science", it seems to have an abundance of naming and dubbing, re-naming and re-dubbing of effects and devices.

I thought the effect was well understood.

The effect appears to be the result of enthalpy conservation in a moving frame of reference.

In a vortex, the outer edges of the system moves at a higher velocity than at the axis.

In an EmDrive I would expect that radiation emitted from the wide end of the cone to transfer more kinetic energy from radiation pressure than the radiation emitted from the narrow end of the cone.

What do the Starship Enterprise and toilet paper have in common? The both search for Klingons around Uranus!

Back in the day I had a D&D Spelljammer ship that had a similar means of propulsion.

Magic from my youth becomes science of today.

the mysterious, "impossible" EmDrive propulsion system

Is it impossible or just highly improbable? Maybe a cup of really hot tea?

400 years ago out-of-control European explorers violated he rights of indigenous America. Now FReepers are excited to violate the rights of rocks and minerals on new frontiers. :)

Been ten years from commercial applications for 20 or 30 years now?

Get it right.

They both WIPEOUT Klingons around Uranus.

Forget the "EM Drive." What we need is the "Infinite Improbability Drive!"

The article tells us nothing. No new information is contained in it. We don’t know if this ‘drive’ works or not.
