This was a cool design. Deserved a better movie.

We’ve known how to create “gravity” in space for a long time, spinning the craft and living in the outskirts. Is it not obvious that getting close to 1g is optimal? Do we need to have people in bed for 60 days to figure this out?

Never mind. Answered my own question.

[Telepathic Intruder]

According the General Relativity, there is no distinction between acceleration and gravity. Spinning a spacecraft will produce the same thing using centrifugal force, except for local effects such as gradients. But tidal force plays the same role in actual gravity. The real danger in space is cosmic rays and solar radiation.

60 days in bed. My teenager would volunteer for this.

Volunteers at the German Aerospace Center will spend 60 days in bed ... at an incline that will send blood away from their heads. Once a day, a "selection" of the subjects will take a spin in the Center's short-arm centrifuge in a bid to send blood back toward their legs.

Anyone else see a problem with these sentences?

Doesn't the incline do the same thing as the centrifuge? Shouldn't they be investigating the opposite?

Didn’t thecGermans already do these experiments a few decades ago?

You would think that it would be easier to spin a section of the craft.

If the feeling of spinning bothers them, tell them to keep one foot on the floor when they try to sleep.
