Radio Waves Employed in Space Construction

CDeity writes "Researchers at the Georgia Institute of Technology claim that radio waves could be used to shape and fuse debris in space to form massive structures according to this article. Scientists have in the past employed sound and light waves to position small particles, and every expectation indicates these techniques could work on a large scale. One engineer estimates " it would take approximately one hour to form a rubble cloud into a 50-meter long enclosed structure.""

sound waves?

[GoatPigSheep]

how can you use sound waves in space? I thought that in space there is no sound. With no atmosphere, how would sound travel at all?

Maybe there is sound in space on tv but it's not so in the real world.

This has been a fallacy that has urked me for a while.... now tell me how the hell do we use RADIO telescopes to do research on extraterrestrial phenomenae?

No sound in space huh?! Well, maybe nothing you or I could hear, WHILE in the VACUUM of space.

The only reason we can't hear in a vacuum is that OUR ears need a media such as air or water to carry the sound waves to them. Radio waves which BTW != "sound waves" can travel though space or a vacuum just fine. Again this is why we can 'listen' to natural events like supernovas via our radio telescopes.
