I watched avatar 2 and got hard when this showed up

need to mine some unobtonium for that

Realistically, Starship is probably a stepping stone to something closer to this. If Mars habitation/colonization takes off, we'll probably see something similar to Avatar where a fleet of giant, exotically-powered, space-optimized ships are built that can do the trip in a fraction of the time that the methalox Starships can, and as a result, aren't necessarily limited to the biennial synods either. Build 20-30 of them and have them more or less constantly doing the round trip, while getting refueled and resupplied by Starships/New Armstrongs/whatever the Chinese cook up at either end.

It is better for interstellar spacecraft to use a tractor configuration due to some materials are stronger when applied with tensile stress than compression stress.

So at this point, if we end up getting to Mars in the 2020s with Starship and New Armstrong, and things keep accelerating from there, what are the odds of us seeing an IRL version of pic related before the end of the century?

Fusion's taking so long that at this point I'm convinced we're going to leapfrog past fusion space propulsion and go straight to Avatar-style directed matter/antimatter reactions.

Face it, we are not going to Mars in next 50 years. We need ship that can get there in one month.

In all seriousness is there any logic in trying to colonize poisonous wastelands like Mars instead of building large space stations?

If BFR really works and can put giant loads on orbit for peanuts why not put together a larger ship on orbit that could take landing pods from Earth to Mars and back much faster?

Okay, so how exactly is Mars colonization possible with 100-150 days travel time one way?

If just one ship has an accident the entire plan goes to hell. With no way to help your colonists.

Where does the desire for knowledge come from? What made science and math? Most living things seem to just go on about their existence day by day, yet we try to accumulate information, refine it, for the sake of obtaining newer information. How do we do this? It seems so absurd compared to everything else around us. Was it a survival mechanism? Was reality so horrifying that our assumptions about how thunder and lightning was formed was no longer enough? did a handful of people born with god like brains just said "wait a minute there's a trend here, lets see if i can reproduce it by utilizing some symbolic representations."? how? where do you go from a number system built from just symbolizing objects to shit like continuity, smoothness, infinity, precision, and structural things like symmetry? the concepts seem to be born from basic things like realizing a reflection can retain the original objects detail, but we went so far off from this. I just can't understand what direction our brain takes with memory, intuition, and logic. I mean even with logic there are issues like definition negation or a statement in nature. I can't figure out how the transformation is physically, or if it has to be physical. I mean physical as in the representation was something we extrapolated from nature as old age humans, and built on it some more advanced concepts, but is it all just an amalgamation of basic ideas that deceives people into thinking it's highly advanced, or is this naive? The distinction from a really detailed model of the world, versus a model that is potentially capable of such a thing but is more mathematically succinct for grander generality, makes me question what compels our minds differently from other living organisms. why is there such a disparity? what weight factor exists such that we are isolated in this ability to not just symbolize, but optimize our symbols, representations, and even now realize that our models are incomplete...

will people 100s of years from now look at us and think of us as we think of people who thought shit like the earth was flat and that heavier than air flight was impossible? how do you cope knowing that someone in the future will think you're a retard?

Yeah, I was thinking more intense war.

Civil wars would be very interesting if it actually was forced into a more low key planet occupation.

How do you attack? Moving troops/killbots over such a massive distance would cost stupendous amounts of time and effort. The defender on the other hand can just pump out troops and defences non-stop. The attacker would need a massive technological advantage or just be so much larger they actually can move the amount needed to win in a single operation. You could never win an attack with an even enemy aside from outside manipulation (political ect.)

Even if the attack was willing to use limited orbital bombardment it would be a nightmare.

Why are we so obsessed with warp drives, wormholes and other sci-fi stuff that most likely will remain sci-fi for centuries when there is over a dozen of star systems within 10 light years? They are within reach even without FTL drives.

Yes, it will take years to reach them, but our probes are also taking years to reach destinations right now. New Horizons was flying to Pluto for 9 years.
