Plans have been submitted to build the world's deepest pool in England.

The proposal is to build a pool that is 40 metres wide and 50 metres deep in Cornwall. That's nearly as tall as Nelson's Column in Trafalgar Square in London.

It would also be the world's largest pool in terms of volume. That means it could contain the water from 17 Olympic-sized swimming pools.

Known as the Blue Abyss, the pool would be used for researching extreme environments.

It could also help develop underwater robotics and train astronauts.

What will the £150 million pool actually be used for?

The company which wants to build it. Blue Abyss, says it would be used for underwater film sets, to test remotely-operated vehicles and train deep-sea divers.

It believes the site could also mirror some sections of the International Space Station so it would be ideal to train astronauts.

British astronaut, Major Tim Peake, said: "This project will help us to widen our knowledge of how humans and technology can function in extreme environments, for the benefit of people and the planet."

What will it look like?

The pool would have a sliding roof and a 30-tonne crane.

The crane would enable large and heavy objects to be lowered into the pool.

Blue Abyss says its project could create up to 160 jobs and would bring in around £8 million a year for the local area.
