During Gamescom 2014, Sean Murra, co-founder of No Man's Sky, was interviewed with IGN. According to the rough estimations, his universe exploration game from Hello Games reveals that it will take a player a time span of more than thousands of years to explore every planet in the game, given the player spends only a second on each one.

According to the developers, even if Hello Games were to share the exact number of world players' visit, it would be incomprehensibly big. What they have provided is a rough estimate of how long it is going to take to explore every planet in the game. It has turned out to be exactly five billion years and that's with no bathroom breaks.

He said, "Given that the Earth's sun has about 4.6 billion years of fuel left before it flickers out and dies, that pretty much ensures no one will ever see every planet in No Man's Sky".

The team earlier has used 32-bit architecture but it wasn't satisfied with the already massive cosmic scale ad that wanted to go further. So, they used a special method to generate all the planets in No Man's sky. They shifted to 64-bit to create an infinite universe but later on opted for 64-bit architecture to generate worlds.

When 32-bit numbers were being used, it meant that it would take several thousand years to visit each planet for one second. But after moving to 64-bit numbers, which can store the astronomical sum of 2^64 total values, Hello was able to ensure that it was even more difficult to comprehend just how many planets No Man's Sky has.

The open-world game was first revealed last December. Now it will be released in 2015 for PlayStation 4. A PC version is also under development.
