A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

On the contrary, I'd recommend looking up the Fermi paradox. It exists because if we assume that ftl is impossible, both in a literal and effective sense, a civilization with the capability of long-range subluminal travel would still have the ability to colonize the galaxy within a few million years.
Now, you might be tempted to think, "okay, so a few million years from now is when we'll start seeing them", but that's assuming they took as long as we did to evolve intelligence. If I'm not mistaken, there's some speculation that dinosaurs were a significant contributor to delaying the rise of mammals, and those were around for over 100 million years. What if a civilization skipped the "oppressed by giant lizard-birds" stage? The result is that they'd potentially be millions of years ahead of us technologically.
Also, because I regularly see this question pop up in any conversation involving aliens,
"why would they come to our world? They've probably got everything they want!"
Why does a human want to explore the ocean? Why does a human want to explore space? Curiosity. Maybe they want to see it for themselves instead of looking at pictures that their friends posted on Spacebook. Maybe we're small and adorable to them. There are plenty of reasons why they might check our world out that don't involve conquest, genocide, slavery or other symptoms of rampant capitalism and authoritarianism.
Why would they send a probe to inspect ships from a visible distance? They could fulfill all their curiosity from lightyears away
No? If you think that's actually an option, then you need to go outside and touch grass; and I mean that seriously. If you really think that looking at something from so far away that it literally takes years to teach you is a suitable replacement for being there in person, then you desperately need to touch grass.
If an alien wanted to visit the Earth, they would actually die hundreds to thousands of years before they would ever get here.
It's simply just not worth the trip, when only your thousandth generation descendants would actually survive to make it.
Now, if aliens actually had warp drive technology, millions of years in the future from our technology, they probably aren't even going to bother visiting us because we're so archaic.
Not necessarily.
A) that's assuming they have similar lifespans to humans. They could be significantly shorter. They could be significantly longer. They could be artificially extended via medical science.
B) that's assuming they're travelling on a small ship and not a multi-generation colony ship. Such a ship would be designed for people to be born, live and die in space.
Not necessarily. First of all, humans nowadays aren't a whole lot more intelligent than humans 6,000 years ago. The reason why we seem to be more intelligent is because there is more which is known about our universe, we put more emphasis on knowledge, and because we have more ways of expressing that intelligence.
Secondly, I'm skeptical that it'd truly take millions of years to develop warp/warp-like technology. Tbh I think it's more likely that we're far closer to developing it ourselves than we realize, it's just that we have to be more active in space to see what we're missing.
However to connect this to my previous statement about intelligence, most scientists put ftl-like travel (I'm talking about the FTL-but-not-really technologies like warp or wormholes) a couple thousand years away. Now, again, I'm skeptical that it'd really take us that long, and I'm pretty sure they're just throwing out a really big number to make the point that you shouldn't hold your breath, but let's pretend that they really meant it. If ftl-like tech is really thousands of years in the future, that still potentially puts aliens in the realm of "near human-like intelligence".
At the end of the day though, this is all conjecture. None of it can be proven (yet), so it's all speculative. That being said, open your mind. Imagine other possibilities. There's so much stuff around aliens and future tech where people assume this, or assume that, but the truth is that we don't know shit. Aliens could be exactly the same as us. They could be so different that they can't be understood by us. They could be somewhere inbetween. They could be far more advanced than us. They could be less advanced overall, but got very lucky with a handful of technologies. We don't know.
The Fermi Paradox is based on our understanding of physics, largely based in a 3 dimensional universe/reality. If these things are inter-dimensional, do those same rules apply?
What if physical distance, as we perceive it, is something unique to us as beings that perceive and navigate the universe in only 3 dimensions?
