No, ordinary conversation isn't possible in space because sound requires a medium like air to travel. However, astronauts use radio communication to talk, as radio waves can pass through the vacuum of space.

FAQs & Answers

  1. Why can’t sound travel in space? Sound needs a medium like air or water to travel through, but space is a vacuum with no medium, so sound cannot propagate there.
  2. How do astronauts communicate in space? Astronauts use radio communication systems that send radio waves, which can travel through the vacuum of space, allowing them to talk to each other and mission control.
  3. Can radio waves travel through space? Yes, radio waves are electromagnetic waves that can travel through the vacuum of space, enabling communication between spacecraft and Earth.
