Answer 2

Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Astronauts are so far from the Earth that gravity is so small. There is no atmosphere in space, therefore propagation of sound is not possible there. Sound needs a material

medium for their propagation. In the

space, there is no material medium so

astronauts cannot listen to each other.
