You might think you've seen it all via live stream. Whether it's historic rocket launches, the strawberry moon, or the introduction of a revolutionary videogame console, it's easy to take our ability to see things unfold in real-time over the internet for granted.

And yet, there's one live-streaming frontier we've yet to fully breached — the deep sea. Communication through water isn't quite as simple as through air and space.

Now, a new study shows that a type of aquatic internet can send data through light beams to allow divers to instantly stream footage from under the sea to the surface.

With our current technology, divers use hand signals, radio, or acoustic or digital light signals to communicate. While these allow fairly effective communication, they have their limitations.
