1.For example, my computer's wireless network card and the wireless receiver connected to my other computer both have a maximum distance of 1 mile. This means that if I moved the computers more than one mile apart from each other, I would not be able to send a file from one computer to another. However, if I had a stronger receiver on my other computer, would I be able to increase the distance the computers could be apart, or would the radio wave transmitted by my computer completely disappear after one mile? Everything should have limits,even radio-waves... So,I was wondering, is there a limit on how far radio waves can travel in OUTER SPACE OR ON OUR PLANET EARTH? Is there ever a point where a radio wave signal disappears and cancels completely, and can't be recovered no matter how powerful the receiver is? Why radio-waves can't be destroyed?Is it because of magnetic fields that "keep" integrity of radio-waves(that's why they're called electromagentic waves,since they both have electrical charges/fields and magnetic fields,so if there are no magnetic fields the integrity of the radio-wave and infomration inside of it(inside of the radio-wave) would dissipate,get destroyed without an possibility of coming back? How quasars send extremely powerful radio-waves 12 billion light years away,on which frequency and how do quasars do it?Is it because quasars are extremely powerful mediums for sending radio-waves?How are magnetic fields supported(what gives the energy to magnetic fields) all the time so the information in the radio signal doesn't get destroyed? Does anyone knows a website which explains that in details? Big thanks!
