How can solar radiation travel through a vaccum ?

I'm learning 8th grade science. No other molecules can travel through a vaccum, but solar radiation can.

How does solar radiation travel through a vaccum?How can solar radiation travel through a vaccum ?Electromagnetic radiation (light) is a magnetic field at right angles to an electric field that propagates through a vacuum at a right angle to the electric and magnetic fields. Em radiation is not like sound waves, which travel by pressing molecules of air together and apart. Sound needs a medium to travel through and transmit it (molecules) Light doesn't need molecules to transmit it..

These web sites will probably make a lot more sense than I do:

Edit:ROFL!!! at the thumb down. Thanks for the confirmation that I'm correct. Are you going to add this answer to the violation list as the 22nd violation? ROFLOL!!!! Oops! TOO LATE, AGAIN. It's after midnight. LOL!!! It's finally cooled down, a little bit. I'm going out to get beer.How can solar radiation travel through a vaccum ?
I was preparing an in depth A to your Q, but when I was ready to post it, you鈥檇 already picked 鈥楤est Answer鈥? only 3 hrs after posing the Q. Anyhoo, since you may still find it useful, here鈥檚 my A:

How can solar radiation travel through a vaccum ?Light is an electromagnetic wave and travels through a vacuum and the atmosphere easily. Visible light is only the part of the solar radiation your eye "sees". You don't see the infra rad (but it feels warm, right) and you don't see the ultra-violet (but you get a sun-burn). Solar radiation extends above the ultra-violet into the gamma rays and below infra-red into the radio wavelengths.



Go find a wall-chart of the electromagnetic spectrum -- it is very interesting.
Because light moves, and there is no friction or gravity to stop it. Science class over.

Also, light isn't molecules. It's photons and electromagnetic radiation waves. Gute Nacht!

And molecules can move through vacuum, if they didn't, we would have seasons, months, years, weeks, and possibly even life, or planets, or stars, or galaxies, or the universe.

Also, someone decided to be a troll and thumbs down all the answers...How can solar radiation travel through a vaccum ?cause its not a molecule, its a particle, no electrons, no bonds, no messy charge separating, just smooth flowin dots flying through space, the problem is traveling not in a vacuum if your a particleHow can solar radiation travel through a vaccum ?
Light can travel anywhere,even through the vacuum of space.
all molecules can travel through a vacuum...why do you think there is matter in the universe...? You learning your science in Texas? lolHow can solar radiation travel through a vaccum ?
light has motion, 8 minutes from the sun to the earth. and, uh, it radiates...
