Why Hearing a Loud Roar from an Exploding Spaceship in Outer Space is Unrealistic?

Question:

Suppose an audience watching a science fiction movie hears a loud roar as a spaceship explodes in outer space. Why is this unrealistic?

a) Sound travels in space.

b) Spaceships don't make sounds.

c) Audience imagination.

d) Special effects error.

Final answer:

Answer:

A loud roar from an exploding spaceship in a science fiction movie is unrealistic because sound cannot travel through the vacuum of space, requiring astronauts to use radio waves for communication.

Explanation:

The reason why hearing a loud roar from an exploding spaceship in outer space in a science fiction movie is unrealistic is because sound cannot travel through a vacuum. Space is a near-perfect vacuum and thus provides no medium through which sound waves can propagate. In several scenarios, whether astronauts on a moon orbit or those outside the International Space Station, they can see visual events like explosions but cannot hear any sound from those events.

For communication, astronauts use alternative modes such as radio waves, which can travel through the vacuum of space.
