This invisible shield that we live in is weakening in a region over the South Atlantic, leaving it exposed to potentially lethal radiation. Is the Earth losing its magnetic field and doomed to a fate similar to Mars? Many scientists believe the answer lies in paleomagnetic data, and that this weakening may be a precursor to a magnetic field reversal; scientists know Earth is long overdue. However, humans were not around when the last reversal took place, so what does this mean for life?[/size][/quote][/td][/tr][tr=,][td=1,row1,border: 1px solid #A7BAC5][code]Video Codec .....: XviD ISO MPEG-4 Video Bitrate ...: 1951 kbps Resolution ......: 704x400 (1.760:1) Framerate .......: 25 FPS Audio Codec .....: 0x0055 MPEG-1 Layer 3 Audio Bitrate ...: 128 kbps (2 ch) CBR[/code][/td][/tr][tr=,][td=1,row3,border: 1px solid #A7BAC5][img][/img][/td][/tr][tr=,][td=1,row1,border: 1px solid #A7BAC5][url=][img][/img][/url] [url=][img][/img][/url] [url=][img][/img][/url] [url=][img][/img][/url][/td][/tr][tr=,][td=1,row3,border: 1px solid #A7BAC5]  [701.02 Mb][/td][/tr]
