because sound waves cannot travel through space
In most cases, the sound of an explosion will be heard before it is seen. This is because sound waves travel slower than light waves, so the sound reaches a person's ear before the light reaches their eyes.
Because empty space cannot propagate sound.
Kids are both to be seen and heard
Music or sound is something that can be heard but not seen.
Yes, technically, every star is a nuclear explosion, including our sun. Apart from that, you would be able to see a nuclear explosion if one were to occur out side the planet if it was close enough. Out in the country, in the night sky, you can see satelittes that are the size of homes only reflecting the light of the sun flying around. A nuclear explosion could make a flash that is anywhere from the size of a few cities blocks to a mile across or more emitting vast amounts of light from them.
Sound is the vibration of matter and since there is no matter in space it can't transmit the vibrations. However, if hypothetically the sound could travel through space it would reach earth in 137,000 hours, unfortunately, the light of the explosion would reach earth in about 8.5 min that is not applying Newton's law of instantaneous forces, which says that the earth would instantly be released from orbit before anything at all reached earth and this release from orbit would delay the time the light reached earth. then the actual explosion (explosive energy and matter) would reach earth in about 22 hours. so all life would be dead and the planet will have been vaporized 15 years before any "sound" reached earth.

Water is possibly the only thing that can not be caught but can be seen and heard.
It's seen & NOT heard- It means they should not interfere in adult conversation.
It isn't ! A flash of lightening is seen BEFORE a peal of thunder is heard.
