Do we currently have the means of creating a generation ship?
What about one for bacteria only?

Rockets can't propel in the vacuum of space, so no.

See, when you use logic, reason, and actual real science (real physics - not math, which, if you rely too much on makes you extremely gullible and limits your understanding), then you realize rockets only work (definition of work: to propel themselves forward) inside an atmosphere.

They don't and can't work in a real vacuum (space).

So will a rocket which "works in space" (propels the craft forward) ever be invented? No. No such technology can ever exist. Any claims of such tech existing is a fraud and a lie. You want to believe in a fraud and a lie?

>inb4 you parrot "newtons 3rd law!" like an NPC without any thought involved
That law isn't in dispute here. Quoting it to "prove" rockets "work in space" shows you don't grasp the fundamental problem here. The 3rd law is 100% correct but has nothing to do with this. When asteroids floating in the vacuum of space crashes into each other, the 3rd law applies. Likewise, the law applies to objects interacting on the ground on Earth, underwater, and in the sky. Not out in space.

You see, the atmosphere gets thinner at higher elevation until it disappears completely (out in space). That's the issue is here! And you can't get around that issue. Parroting "newtons's 3rd law!" or throwing math equations around, doesn't magically make the issue go away. That's just you avoiding to deal with reality. Man up and stop avoiding reality :)

If you're currently under the "rockets work in space! xd!" spell they cast on you through the entertainment industry and educational system (the indoctrination system), and you want to break free from that spell and shatter the illusion - then see these two educational videos (they play inside your browser):

Second (also important): https://files.catbox.moe/so2rrt.mp4

Once you know that stuff - then you know beyond any doubt rocket technology will never be viable outside of Earth.

>"Not out in space."
I ended up wording that wrong, due to the character length limit. To clarify, I mean it of course applies in space (hence my example about asteroids), but the 3rd law isn't what's at issue here. The absolute vacuum is the issue.

>It is not necessary for the rocket exhaust to push against anything except the ship itself. You see, when the combustion of fuel takes place inside the rocket the exhaust gasses produced expand quickly in all directions. The molecules slam into anything in their path exerting a small force each. Thus some molecules push against the 'right' side and some push against the 'left' side, and all these sideways forces cancel each other out. Some molecules slam against the 'top' of the cylinder, but since there is no bottom of the cylinder, there is no force to cancel this out! Therefore the net force will be in the 'up' direction.
