1G will get you anywhere in the solar system fairly fast.

https://space.stackexchange.com/questions/840/how-fast-will-1g-get-you-there

To travel half the distance to the moon would take about 1.75 hours. The other half distance spent decelerating would take the same amount of time.

Using Days and AU (astronomical units) we can see 3 days will get about 2.5 AU (halfway to Jupiter). 4.5 days will get you 5 AU (halfway to Saturn). 9 days will get you 20 AU (more than halfway to the Kuiper belt)

All of this is over my head except highways and manifolds. But are those manifolds intake, or exhaust?

They must be intakes, because stuff is always getting sucked in.................

Yeah, but somewhere along the way they’ll be doing roadwork if it’s anything like our interstate system.

So, a gravity assist?

I am imagining that their statements refer to movement between planets “without” propulsion.

Obviously we can leave the solar system in a couple dozen years. Voyager has done that already.

As long as they aren’t aluminum. Poor design.

I remember Kip’s exclamation in Have Spacesuit, Will Travel about some BEMs with a sustained 1G acceleration: “Those monsters have star travel!”

That answer is as good as any, better than most.

It’s not star travel until we have some way to deal with encountering objects while traveling at a significant percentage of light-speed.

Which WILL happen over a journey of several light years, regardless of how “empty” interstellar space is on average.

Nice answer, and caveats are always welcome.

They employed a tool called the fast Lyapunov indicator (FLI), usually used to detect chaos. Since chaos in the Solar System is linked to the existence of stable and unstable manifolds, on short timescales, the FLI can capture traces of manifolds, both stable and unstable, of the dynamical model it's applied to.

Wow. My first thought when I saw the picture that it really looked very fractal in nature. Then they mention the above. Lyapunov are a class of fractals easily generated with a program like 'fractint'. Very cool.

A lot of stuff in nature is fractal. Noise in digital transmission lines is very closely tied to the classic Mandelbrot set.

Fractal systems are a very compact way of storing incredible amounts of information and complexity. I would not doubt that there are large fractal structures in the universe, just like there are small ones.

Stargate command found cosmic ‘Superhighways’ for fast travel through the universe.

Not quite hyperspace tunnels or slipstream portals, are they ;?
