and the meter is defined as the length light travels in 1/299792458th of a second. Perhaps reconciling QM and SR/GR will yield a quantum unit in the space-time fabric. Or perhaps not. I do firmly believe that a quantum unit in time or distance will mean that a quantum unit exists for the other, as they are inextricably linked. Aside: has anyone made a black hole mod for KSP yet? Imagine the science points for sending a probe in! Oh wait, it wouldn't be able to transmit home...

Your idea is more practical and near future, but it has the con of the object not appearing to materialize in thin air.

It might take a little fine tuning, but here is my idea: Fire a tiny piece of metal at the target location with extreme accuracy. Upon impact, some of the kinetic energy will be converted to heating the tiny metal particle and parent metal. At the precise moment of impact, focus enough laser beams on the target area to instantly weld the metal particle. A billionth of a second later, focus precise and timed lasers on the area to instantly laser cool the weld. IT may not be fast, but you could build up 3d parts out of metal and the metal would also be amorphous. Laser cooling is an actual thing. One of my profs does it.

Is there a single vehicle requirement, or can i park several vehicles nearby and then swap between them?

Gasoline burns slowly, which is why we use it in conventional engines. A slowly expanding fireball that the steel container can survive.

It's pretty accurate. Einstein discovered that our universe is actually 4 dimensional with time being the fourth dimension. Hence the idea of 4d "spacetime". You are always moving through spacetime. If you come to rest with respect to the spatial dimensions, you will move through the time dimension at maximum possible speed. However, if you move rapidly through the spatial dimensions, you will find that your travel through the time dimension slows. If you manage to propel yourself to the speed of light (unfortunately impossible since it requires infinite kinetic energy), your travel through time will stop.

I think that in the very near future the benefits of human astronauts will begin to disappear... What I am talking about is better robots and post singularity. A human body is better at walking around on a surface and collecting rocks, doing science, etc. A robot is better at being cheap to send and expendable. What if we had true androids that could accomplish human tasks?... their creative thinking would obviously be limited, so we'd still need to communicate. I think that the argument "humans do better science" will melt in our lifetime. However, manned spaceflight is absolutely crucial for long term colonization purposes. Unless we are willing to accept the inevitable extinction of all life on Earth, it is absolutely critical to escape the confines of our current rock and star.

I am on board with the Queen's date convention (dd/mm/yy), but nobody outside of math,compsci, and physics circles seems to agree. How does everyone feel about Tau? (ie 2pi). It seems like a more natural constant to me.

Kaboom, I am going to try to answer your questions succinctly, but in a different order. 3) Space and time are both dimension in our four dimensional universe. You are usually moving through this universe in some combination of a high speed along the time axis and a low speed along the 3 spatial dimensions. It turns out that if you treat time as a dimension, stick the appropriate constants in front, and add it quadrature to your 3 spatial dimensions like you would for any vector sum... everything's speed through spacetime is the same. If you move faster through space then your travel through time slows down to accommodate and vice versa. The relationships are obviously not linear but this is a good way of verbalizing it. 2) This one defies logic for low-speed, low energy, mass based critters like us. It turns out that if you have no rest mass, the rules are different. Actually, they aren't. All the relativistic effects fall out at low velocities. At speeds closer to c, the universe preserves the cosmic speed limit in different reference frames. This means that if we are flying towards eachother at 0.6 C, we won't see the other ship approaching at 1.2C. Velocity transformations from SR prevent that and we end up seeing the other ship approach at a subluminal velocity. Light is just a special case of these maths where it has no rest mass and subsequently sits on the light speed asymptote. 1) Once you accept that space-time is four dimensional and light moves at C for any reference frame, the consequences of time dilation and length contraction fall out quite naturally in order to preserve these relationships. 4) We don't understand gravity. Sorry.

Ah, sorry. I was all stock.

Here's my entry (Advanced Harrier V2): 7:22 I had originally designed my VTOL entry as a bomber, so here's a bombing run on the island complete with landing on the control tower, just for fun. This plane can land pretty much anywhere and has significant payload capacity. It's fairly easy to fly with a little bit of practice. I'd be happy to share the craft file with anyone who's interested.

Equation still doesn't hold.

Containment and dispersal are indeed big problems for directed plasma, so why not try a diffferent approach? I expect plasma grenades will exist in the near future.

2/(3-2.00069)=2.001381 does not precisely equal 2.0014, but does approximately. What your relationship is saying is two divided by almost 1 almost equals 2. The error is 6th order, not 7th and your values are reported to 6th order. I'd say to the accuracy of the reported values, your equation does not hold.

Interesting, I always thought those numbers were exact. Probably a tidal effect similar to how the moon is gradually escaping Earth. Anyway, with the new more precise values of A & B your equation doesn't hold.
