Well I heard long time before about some sounds found by scientists from a deep dig in somewhere (In think is Russia...). They think the sounds came from hell. And a radio station streamed the sounds. Listen the sounds from YouTube: [youtube]A6h2dZ51iy8[/youtube] But for skepticals like me I think we have 2 explains: fake sounds or mixed sounds that came from air and the record system channeled them... What do u think?!
