Why do you not hear explosive sounds produced in the sun?

Answer 1

Sound needs matter to propagate. There's not much matter between us and the sun.

Even if there were matter enough, the sound wave is not unidirectional and spreads out. A lot of spreading can be achieved in a distance that takes light 8 minutes to traverse.

Indeed, it would spread spherically. It's worth pointing out that although sound cannot reach us from the Sun, the electromagnetic radiation (heat, light, etc) that does reach us is subject to the same inverse-square spreading rule, rather neatly because despite the Sun's size, it is far enough away from us and anything else of significant obstruction to be treated as a spherical source in an infinite volume.

Answer 2

Acoustic vibrations cannot pass through a vacuum. Otherwise we would be able to hear the sun make noise. I'm not sure we could hear the fusion, however. Fire is a chemical reaction--it is the combustion of wood. Oxygen in the air combines with carbon in the wood (or material being burned) to form carbon dioxide gas. The sun does not burn via this chemical reaction, but instead burns through a nuclear reaction--the fusion of hydrogen nuclei.

Answer 3

Well think about it - "In space no one can hear you scream" (It's true) Light can travel through a vacuum but alas sound can't as it needs a medium to travel trough.

But get a detector and you can.

Answer 4

because sound dont transfer in space. sounds need medium to transfer throuh.As in the earth it transfer through the air,,but in space there is no air or any medium

Answer 5

The space between the earth and sun is a vacuum, sound cannot travel through the vacuum but light can
