Zero Gravity Rooms on Earth: Last week, I had the opportunity to visit the Ashton Graybiel Spatial Orientation Lab at Brandeis University. While I was there, one of the team members mentioned that they also have an artificial gravity laboratory. This caught my attention because artificial gravity is often associated with science fiction. But it turns out, it’s a real thing, and there’s a good reason why I’m keeping my head straight and forward in this room.
The artificial gravity facility, also known as the rotating room, is a research prototype designed to study how humans adapt to a strange gravitational environment. The idea is to simulate the effects of gravity on astronauts during long-duration space flights. If we ever send astronauts to Mars, we would need a way to generate apparent gravity to keep them healthy. One way to achieve this is by spinning up the spacecraft and using centrifugal force. The rotating room at Brandeis University serves as a testbed for studying artificial gravity and preadapting astronauts to its effects.

When you first enter the rotating room, the first thing you should do is push yourself off the wall and align your body with the direction of the resultant force. This helps you stand upright in the rotating environment. Walking is not recommended, as it can be dangerous due to the unusual gravitational forces.
It takes time for the human body to adapt to the rotating environment. At first, you may feel disoriented and weird when you move your arms. But with time, you can adapt and even perform specific movements without feeling the force anymore. However, sudden head movements can still cause problems due to the inner ear’s inability to adjust quickly.
The artificial gravity lab
To demonstrate the effects of the rotating environment, the team at the lab threw a tennis ball across the room. As the ball moved into slower-moving areas, it maintained its sideways speed, causing it to appear to move in a curved path due to the Coriolis force. This force is not real but appears real in the rotating environment.
The Artificial Gravity Facility at Brandeis University
The rotating room creates a unique visual experience. The circumference of the room is longer on the outside than on the inside, causing objects on the outside to move faster than those on the inside. This creates a distorted perception of speed and motion.
The lab at Brandeis University aims to answer important questions about human adaptation to artificial gravity and the time it takes for individuals to readapt to normal gravity after leaving the rotating environment. The research conducted in this facility will contribute to our understanding of how to keep astronauts healthy during long-duration space flights.
