In all sincerity, maybe rocket ships aren’t the answer here. Theoretically you might be able to establish a “pathway” so to speak, of entangling particles that would create a wormhole. But I assume you’re going for practical answers and not the uninformed ponderings of a sandwich slinging stoner.

This navigation menu is absolut garbage. I was at the "basic" rocket design page. They're just beating around the bush.
They sort the rocket designs by propulsion. Is there a specific rocket design you are looking for?
Oh. Well in that case, just wait. It’ll collide with us eventually.

It’s basically just deciding whether to fold space, or use solar sails
I am not certain our solar system will drift closer to the Alpha Centauri system over time. I will look it up. Solar sail may be workable, but decelerating at your destination star system with just solar sails is tricky.

When you said "folding space", did you mean an Alcubierre drive or an Einestein-Rosen bridge?

Oh. The problem with wormholes is that most proposals, if not all, call for you having exotic matter, usually widen and wedge open the wormhole 'mouth'. Plus, most physicists feel exotic matter is as real as fairy dust.

Idk like paper lol. I don’t think there’s really any “good” conventional method to reach a distance that far, but this might be a start

We should see first if we can transmit any information at all in a fast and efficient way.

Seems to me like someone needs to test the theory and just take one for the team. Just throw some science at the wall and see what sticks.

Btw I’m totally volunteering here

Quantum entanglement could yield an method for unbreakable communications encryption, but if you talking about using the quantum entanglement phenomenon for transmitting data, that is not physically possible due the Heisenberg Uncertainty Principle.
Atomic??????? This site says atomic rockets!!!!
That is just the title for the site. The creators wanted a retro-futuristic funny title.

Small amounts of it have been produced through the casimir effect, but still barely any.
Wait, what? Even one particle of exotic matter, particularly the kind needed for wormholes and warp drives, would be a guaranteed Nobel Prize. That doesn't even fit in the standard model yet.

I can't contribute anything aside from 2001: A Space Odyssey's sequel "2010" will give you an ENORMOUS nerd erection in the theoretical space travel department.

On 4 June 2013 it was reported[52] that a conglomerate of scientists from Hong Kong University of Science and Technology, University of Florida, Harvard University, Massachusetts Institute of Technology, and Oak Ridge National Laboratory have for the first time demonstrated a compact integrated silicon chip that can measure the Casimir force.[53]
If we truly are going to jump down the wormhole, I suggest we read this:

In physics, exotic matter is matter that somehow deviates from normal matter and ... exotic matter is the region of pseudo-negative -pressure density produced by the Casimir effect.
Exotic matter - Wikipedia
That's not "producing small amounts of exotic matter", that's just a speculative interpretation of an analogous phenomenon. Hence the "The closest known real representative" part, which you should have added in that quote.

There is also this book I have which states it in

That's great, but the point is that the Wiki article you linked talks about the casimir effect itself being a hypothetical negative-mass quasi-particle, an analogue of one or something in that vein.

So while interesting speculative thought experiment that might go somewhere one day, it is not as you put it "producing small amounts of exotic matter".

Eh, I couldn't be asked to read it that much before linking :p
I would send a picture of the page in the book but I can't find it right now

I’ll point out that the term “quasi-particle” is extremely important here. That puts these in the same category as electron holes and phonons. They’re typically mathematical constructs that make aggregate stochastic calculations easier and aren’t actually matter. For example, when dealing with a shit ton of electrons in a P-type semiconductor, it’s way easier to model a hypothetical positive particle moving through the substrate rather than all of the electrons. If I understand correctly, the Casimir Effect results from “filtering” the zero-point fluctuations of the electromagnetic field. You can have a negative differential, but the field to my knowledge has a strictly positive energy. Modeling the experiment as a negative energy quasi-particle in a zero-valued field might make calculations with a negative differential easier just like a positive quasi-particle did, but that is very different from producing a negative energy particle.

Right but the solution for landing would be inverting the sail to make a more solid landing. I think? XD

Nuclear "pusher plate" drive and a bi-generational starship. at a quarter the speed of light, it would take about 80 or 90 years to get there.

antimatter is a great theoretical fuel but it is nearly impossible to produce sizable quantities of the stuff, and storing it is another issue.
solar sails would be impossible to slow down.
we don't even really have cold fusion down yet, let alone an idea of how it could be used to power a spaceship in the future. that's
not to say it couldn't be done though.
