How is zero gravity environment created on earth for astronaut training?
What is Zero Gravity club? Why aren't the astronauts pulled by our earth's gravity? What would happen if the Earth's gravity becomes zero for 2 seconds? What kinds of anti-gravity performance tests do astronauts need to go through? What would be the gravity in Mars? How could one reduce gravity in a room on earth? What is gravity on Mars? Where could a person feel the maximum gravity on earth? What does it feel like to masturbate in a zero gravity environment? Is there gravity in space? What are the application of specific gravity? What were the most important experiments done in zero gravity? How do different animals respond to zero gravity situations? What is the acceleration due to gravity on Mars? Can we artificially generate gravity? To terraform the interior of Mars using DUMB (Deep Underground Military Base) tech, what kind of turbine would I build to create additional gravity? What happens when we switch on elecrtical fan in zero gravity? What is the minimum required gravity to maintain the presence of any atmosphere? What do astronauts do in outer space?

How was the first astronaut suit designed if no man has ever been to space then? How is the gravity work? Is gravity of the earth constant? Is there gravity in mars? Lets say that gravity turned off for 5 minutes max. What would happen to earth and the people on it? What kind of training does astronauts go through? What is specific gravity? In astronaut training, astronauts ride on a huge centrifuge to make them experience high accelerations.  Is this only to test how their bodies react to such large g-forces?  In other words, does actual spaceflight also produce motion sickness? What happen when helmet of the astronaut are opened in the space?
