On a SpaceX rocket. 😳

The company says I'd defies known physics.

Limitless power from (a) sun. Even if it works, it will be limited to travel around our solar system, but utterly useless for inter-stellar travel. Nonetheless, I do hope that it proves to work as the developer's hope!

I won't be around, but whenever scientists finally manage to crack the secrets of gravity plates, that will be even more exciting!

Well they are taking about Newtons laws of motion here which are not universal. There may very well be universal physical laws but as soon as something demonstrably defies the physical laws we think are universal then we know what we have only approximates what those laws would be.

I predict the first truly successful replacement for ICE in personal transpertation will be hydrogen. It's portable and you can carry around spare fuel in tanks. Shutting down the grid for a week will not bring cities to a halt due to the spare tanks everyone can store. The only gases released during consumption is water. Like batteries, hydrogen is not a fuel but only an energy storage system, you have to make it with solar, wind, or burning hydrocarbons. But it's volatile and tends to float things away, like the Wizard at the end of the Oz movie.

Not sure why you mentioned that. Nothing to do with propulsion in space, but no, ships lorries maybe, but not for what we drive, batteries are miles ahead with 1000 mile batteries and all manner of tech incoming in a few years. There is hardly any of the complex, expensive infrastructure for hydrogen in place and almost all hydrogen is made from fossil fuels. 

Can we stay on topic though, or moderators will tell us off.

This quantum drive experiment is said to be about quantized inertia, which is controversial.

It will be launched on a SpaceX rocket in a matter of hours, so it will be interesting to see what transpires. According to the company involved, they carried out all manner of vaccuum chamber tests and verified it worked. So testing in space is the next step.

This technology is based on a hypothesis that is hardly discussed at all among researchers. Having said that, I am looking forward to the test. Experimental verification is precisely what a scientific hypothesis needs to succeed (or fail), so they are following scientific standards with this launch.

A shield 4cm thick would be enough to protect the spacecraft from cosmic impacts at 50% the speed of light? I assume that they are only expecting hits from dust grains?

The launch. I'm presuming its on board. Its not been mentioned in the video. 

9 landings, same booster, So impressive.

That landing looked at bit dodge when one leg on the left when down smoothly but two of the others looked like they got stuck for a second. Is that typical?

Re: the Mike McCulloch video.

The DARPA grant was given in 2018 for a four year study. The video presentation was in September 2021 with interim results from Madrid so now, in November 2023, we should expect final results, including those from Dresden.

Here is a 2021 paper from Dresden. Are the results on page 20 relevant?

Yeah I noticed that. A bit more precarious than usual.

Some ground crew forgot to lube them with WD40... 😂
