If light waves required particles to transfer their motino, as sound waves do, would we still be able to see the sun, moon, and stars? How would the conditions on earth dffer?

see its not in my book and i dont know we have to think about it and like the book isnt clear about the ligh waves and the quantom theory or whatnot

No, we wouldn't be able to see anything in "space." While space is not empty, it's nearly so -- and the particles there (mostly gas molecules) are very widely seperated -- so light would not transmit in space if it required particles.
If that were the case, there would be no life on earth, as we would not see the sun nor receive energy and warmth from it -- it would be constantly dark everywhere in the universe except where there was an atmosphere or a thick concentration of gas or dust.

Is there enough matter between us and the sun to transmit sound waves? Interplanetary space is silent, isn't it? So, if light needed the same conditions as sound does to be transmitted, would light be transmitted from the sun to us? From the stars? From the moon? How much light would there be on earth? Would plants be able to grow? What would animals eat, if there were any?
Bonus point: The sun is powered by nuclear reaction, like atom bombs. By all accounts, a nuclear explosion on earth is very loud, though much tinier than the sun. Why can't we hear the nuclear activity of the sun.

You would not see anything beyond the earth (sun, moon, stars) because there are no particles in space. You would see things on earth because of the particles in the atmosphere

We couldn't see the stars because we would not be here. The earth (if it would form at all) would be at zero degrees absolute. The radiation of the sun would have no way to travel to us.
The light from the sun give us the heat required for us to exist.

if u have clear understanding about light waves you can say that light requires no medium to propagate... or in your words these are particles....
you can change the property of a wave as light waves are transverse waves and sound is a longitudinal waves....
i mean there is no necessary in making light to travel if and only if there is some sort of medium.. and to add up light can travel thro' medias which are opaque and transparent.......
is that u r ques..... if i didn't answer yours .. kindly mail me....

earth will be cpmletely dark. as sun's light couldnot reach earth.
and there would bno plants only soils no creatures but some exceptions.

Check in your book. I am not that sure but I would say no. If it is not in your book guess. If it is graded, try and get it off one of your classmates

If that happenned, nothing would exist as we know it.
