Sean Murray, co-founder of No Man's Sky, a randomly generated universe exploration game from Hello Games, explained the vastness of the game during Gamescom 2014.

Developers have given a rough estimate on how long it will take to visit each planet in the game: 5 billion years to be exact.

In the procedurally generated universe game, it will take an extraordinary vast amount of time to explore all the planets and not just one second to explore one planet let alone one minute.

In the demo shown during Gamescom, the game promises a massive space exploration spree where players won't run out of new worlds to explore and visit.

During the game's early development stage, the team used 32-bit architecture but later on opted for 64-bit architecture to generate worlds.

Murray said a 32-bit architecture means it will take a player 4,000or 5,000 years to explore every planet in the game, given the player spends only a second on each one.

The team obviously wasn't satisfied with the already massive cosmic scale so they shifted to 64-bit to create an infinite universe. There are those who challenge the game's technology (because all technology has its limits) as to whether it's truly possible to create a universe on that grand scale, infinite and colossal.

Now, it will take five billion years to explore each planet in No Man's Sky endless multiverse for every planet in the game.

It's the biggest game world ever created to date.

The open-world game was first revealed last December during the Spike Video Game Awards and will be out for PS4 early next year. A PC version is also in the works.
