Is scuba diving really like being in space? Let’s find out! First, let’s take a look at the differences between scuba diving and outer space when it comes to similar feelings or sensations in relation to gravity (or at least similar ‘feelings).
Astronauts train in tanks with scuba diving equipment because it allows them to experience an environment of neutral buoyancy. Essentially, you’re sinking as much as you’re rising, or remaining almost neutral (or floating) as part of the environment around you.
Okay, so what are some of the main differences between diving and being in space?
The first difference is that your body is different when you’re in water than when you’re in space. And breathing while you are underwater presents a whole new set of challenges than breathing in outer space does. For one thing, it’s much more difficult to breathe through an oxygen tank when past a safe depth underwater because the pressure from the ocean squeezes down on your lungs. The second difference is how accessible air is in outer space. If there’s no air, you don’t have anything to breathe. When you go scuba diving, the tanks are filled with air and can be easily accessed at any time. Either way, you’re not going to last very long without breathing apparatus in both scenarios.
Another difference is that scuba diving instruments like gauges and computers which monitor important things like depth and oxygen need water and light to work properly. They also need power from batteries. In space, these instruments would not work because they wouldn’t be able to get power or use their screens and gauges correctly without the influence of Earth’s gravity. So if you were in outer space without a spacesuit on, you wouldn’t be able to monitor your oxygen levels, depth, or any other important information about your dive.
If you’re really intrigued, then get booked in at your local scuba diving center. It’s a peculiar feeling and one that is addicting once you get the hang of the ‘weightlessness’ – you really will feel free!
