What happens when an object vibrates in space?

• It doesn't create sound waves because there are no molecules to carry the vibrations.

• It creates sound waves that travel through space.

• It creates electromagnetic waves instead of sound waves.

• It causes a chain reaction of explosions.

Why can you see an explosion in space but not hear it?

• Because light waves can travel through the vacuum of space, but sound waves cannot.

• Because explosions in space don't emit sound waves.

• Because the light from explosions is much stronger than the sound.

• Because sound waves are too slow to reach the observer.
