Thread: Thoughts on expanding life under the sea?

We have seen it in video games, TV shows, and movies but what are your thoughts on actually doing it in real life?

I feel like this is something that should be explored more because our technology can evolve to allow people to actually live, work, and thrive underwater which would expand livable space as the world's population continues to grow. I think starting this could lead to oceanic subways that are safer and less damaging to the planet as say planes are as well.

What do you think about it?

I'm pretty scared of the ocean and fish so that's gonna be a no for me dawg. I get that it may be suatainable or make better use of the square footage we have access to on Earth but i'll remain on good old dry ground like a Boomer.

Not that I haven't been on cruise ships or flown over the ocean & stuff like that but if I have to confront deep water too directly then I lose it.

Edit: Oops, I lazily misread the OP. My actual reply is further below but I may as well keep this here anyway.

Yikes. The terrors of the deep in VR! Only for true and honest men!

But anyway, I am 110% for exploring the deepest depths of our oceans. Why? Well, it's been argued that we know less about those places than space. Pretty crazy, huh? Look at how amazing these creatures in the midnight zone look:

But yet, the midnight zone is far from the bottom in many cases. We've already been to the deepest of the known deep (there may be areas far deeper):

Well, if it's anything like Bioshock then my initial thoughts are



Although realistically I'm not sure how feasible that would be

Depths scare the pants off me more than heights I think but I never had an issue swimming. It is what I can't see that scares me. Even still, I feel safer with people living underwater Bioshock style vs people moving to mars but that is just me! lol

I actually think oceanic subways are a great idea, even if they're just going from one land mass to another, because like you said it's safer and much less harmful to the environment than ships and jets.

Damn, I guess I was really tired when I replied to the OP because it seems I misread the title's "expanding" as "exploring". Actually reading the OP changes a lot of things...

I think it's a great idea if done right. It'll be a long time until we can colonise another planet or moon. I already have experience travelling underwater.

Of course, we finished the (to my knowledge) first successful underwater tunnel in the 1990s, the Channel Tunnel. I've taken the Eurostar to visit Paris in the past.

Despite not having a view it was easy to forget that I was travelling underwater. I think an actual society could exist underwater too. Surely it would be inexpensive compared with space colonisation.

One of Saturn's moons, Titan, could actually be the best candidate for space colonisation. But think about how long it would take to get there. You'd be spending a significant amount of your life just going to visit family on Earth. Then there's the return journey. We're talking years. Unless there's no intention to visit Earth this will never be realistic without light-speed travel. I'm no expert but I doubt that will go beyond science fiction. I said Titan is a good candidate, but that isn't saying a lot since it's still a lethal environment.

On the other hand I can imagine a visit to the surface of Earth being a rather short journey. Inexpensive too when you consider the cheap (compared to flying) cost to visit another country with Eurostar. I think an underwater city would have both trains and lifts.

I like the idea and it's something that will in my opinion happen long before space colonisation. The world's population is at around 7.8 billion now. By 2030 it'll likely have grown to over 8.5 billion. By 2050 we'll have almost reached 10 billion. Underwater cities are simply an inevitability.

Because of the increased population, do you think this will actually happen in our lifetimes? Like seeing underwater places of business, public transport, and even housing? I feel like it will eventually get there but I still think we are a ways out from it. I think there will be a lot of mistakes before it gets perfected.
