The same is true for radio waves when you beam them underground. They have to be powerful, because the waves have a long way to travel to get to the good stuff. Hundreds of metres.

I say, enough of fear-mongering about radio waves. If you don't like smart meters, fair enough. But find other reasons to oppose them, and get off the "radio waves are dangerous" soapbox.

When it comes to space, there's a lot of exotic phenomena out there. Among the most mysterious are fast radio bursts. These are immensely powerful bursts of radio waves that come from the depths ...

Dubbed GLEAM-X J0704-37, it produces minute-long pulses of radio waves, just like other long-period radio transients. However, these pulses repeat only once every 2.9 hours, making it the slowest ...

And we’re not just talking about a little blip of radio emission. Every 22 minutes, it emits a five-minute pulse of radio wavelength energy, and it’s been doing that for at least 33 years.

A cosmic enigma Now, researchers are trying to figure out the source of ASKAP J1832-0911’s radio waves and X-rays, which don’t fit into a neat box for categorization, and whether it’s truly ...

This object emits radio pulses that last a minute, like other transients, but at a slower rate—once every 2.9 hours, making it the slowest one discovered so far.

A battle is raging in Ukraine in the invisible realm of electromagnetic waves, with radio signals being used to overwhelm communication links to drones and troops, locate targets and trick guided ...

Slowly repeating bursts of intense radio waves from space have puzzled astronomers since they were discovered in 2022. In new research, we have for the first time tracked one of these pulsating ...
