Made me think of this Futurama scene.

It is much more complicated and difficult to explore the depths of the ocean than going into space, given that in space there is no need for vehicles that must withstand these enormous pressures. In space they only have to withstand an air pressure of 1 atm and not a thousand atm in the depths of the seas. A simple crack in the hull and you’re dead before you can say sh…

Wait till we get far enough in space.
The voids will prove harder than the oceans.

No, space is hard because of radiation and great distances, but a hole in the hull of the ship, for example due to a micro meteorite, can even be covered with a piece of duct tape. A hole in the hull of a submarine however is a catastrophe, if it does not directly cause the hull to implode, the water that enters has enough pressure to cut you in two.

The current “space” we go into, tends to have a tinny amount of atmosphere. (1.322×10^-11^ Pa according to some random top result on Google)
So if you want to keep inside conditions at around 1 atm for a human to stay, that’s all the difference you need to keep, and a duct tape might work.But the void I refer to, is very different.
Think:- Vaporising metals
- Theoretical quantum bubble formation
Normal spacecrafts made for “space”, might even have their outer surface constantly being diffused in the void.
Disclaimer: I’m not a space nerd. The above is just speculation

Sure, but doesn’t the outer surface diffusing apply to the friction of water against a submarine’s hull too? No clue about theoretical quantum bubbles, but it doesn’t seem like anything that would affect spaceships in particular.

Just like how we explore moon/mars, we been using remote controlled submarine for quite a while now

The challenge of deepsea is not pressure, it’s the limited visibility and range they can get with the submarine drone. On moon and mars, everything on the horizon is visible once the sun hit the surface, but deepsea doesn’t have that perk, and water block any radiation so well the submarine need to be tethered in order to receive signal and send video feed.
