Galactic 'geographic' features, how could they impact galactic colonization efforts?

STL travel is limited to shielding concerns. Do the figures about how much heat you have to get rid of per square meter, punching through vacuum at 10% of c, with a typical gas density of 1 atom of H ...

How would a spaceship not affected by gravity navigate between planets?

Fuel consumption will make your math more complicated... but the technology is still worth exploiting If you have a rocket ship in a perfect state of null gravity, and try to launch it, it will ...

How would a spaceship not affected by gravity navigate between planets?

Please do NOT do this. It's trivial to show that any kind of anti-gravity thingy is in fact a infinite energy source (i.e. even worse than a perpetual motion machine). If you recall basic General ...

How would a spaceship not affected by gravity navigate between planets?

LaGrange points aren't just a gravitational phenomena. They're based on both gravity and momentum. L1 would still exist as a quasi-stable null gravitational node, but for all of the rest, momentum and ...

How would a spaceship not affected by gravity navigate between planets?

Hmm... Interesting. You could use X-matter's antigravity to get out of the Earth's atmosphere, I suppose, but I don't think there'd be much point. X-matter is probably expensive, so you wouldn't want ...

How would a spaceship not affected by gravity navigate between planets?

It would be utilizing Null matter to reduce fuel required on take off and/or reduce the hassles from landing process since less acceleration needed = less fuel required to do so(ie orbiting/creating ...

Galactic 'geographic' features, how could they impact galactic colonization efforts?

Just yawning stretches of emptiness. Perhaps civilisations like ours in the spiral arms can only really hop along the arms. Travelling large void areas would just take too long. Perhaps all the ...

Galactic 'geographic' features, how could they impact galactic colonization efforts?

Flipping Black-holes. They normally have predictable rotation, an accretion disk that behaves in a nice orderly fashion and an ejection of x-rays and very fast ions in regular and expected directions ...

Galactic 'geographic' features, how could they impact galactic colonization efforts?

That's a good start for space hazards. Even though humanity has only dipped our toes into space, we are still very concerned about radiation. Not only is there a cancer risk, but there as also a risk ...

Galactic 'geographic' features, how could they impact galactic colonization efforts?

Gravity and radiation might make them difficult to contend with, but who cares. Because if you're only moving to close stars you won't be getting anywhere near them. So they shouldn't be problems.

Day/night cycle and tracking celestial positions in S-type binary star system

A habitable planet orbiting an F5.5 main sequence star, 1.2 solar masses, at a distance of about 1.5 AU would have a day/night cycle similar to that of Earth. The secondary star, a K-type about 0.5 ...
