Jeff Bezos has revealed what it felt like to float in zero gravity.
The billionaire founder of Amazon was speaking on the Lex Fridman podcast, and described the sensations he had felt while weightless above Earth.
Bezos has previously announced he will be stepping back from Amazon to focus on Blue Origin, an aerospace and defence company which also pushes further space exploration.

Bezos has since personally been on a launch of the Blue Origin rocket, which saw him enter a zero-gravity situation before descending back to Earth.
Now, Bezos has revealed what it felt like for him to be in a weightless environment.
Speaking to the Lex Fridman podcast, he said: "I'll tell you something very interesting: zero gravity feels very natural. I don't know if it's because it's like a return to the womb."
He added that he had not felt 'nervous' during the flight, saying: "It was an incredible experience and we were laughing inside the capsule, and were not nervous."
But what about the philosophical impact of such a flight?

The multi-billionaire described how it would be enough to make someone an environmentalist.
He said: "You see how fragile the Earth is. If you're not an environmentalist, it will make you one."
Bezos has stepped back from Amazon in recent years, instead focusing on Blue Origin.
"Most of my time is spent on Blue Origin and I'm so deeply involved here now for the last couple of years," he said.

Among the people to have flown on Blue Origin is billionaire Hamish Harding, who was one of the five people killed when the Titan submersible imploded on its Titanic expedition.
The Amazon founder also shared his vision for what the future might look like for humanity in space.
This was very different from that of fellow billionaire and space enthusiast Elon Musk, who himself is more focused on putting together a successful human expedition to Mars.

As for Bezos, he seems to be more of a fan of the 'hive ship' idea, where people live on self-sustaining space ships.
He said: "The only way to get to that vision is with giant space stations. The planetary surfaces are just way too small unless you turn them into giant space stations."
This is one theory about how humans can traverse the enormous distances in space without going at the speed of light.
Generations of humans would live and die on the spaceship before it finally arrived at the destination.
