I remember someone posting something about how we woud only have a few minutes warning from SOHO if the sun went nuts... exploded...
But we would have no warning whatsoever. Say the sun explodes, boom,
and SOHO detects it. Wouldn't we be able to see for ourselves the destruction at the same exact time frame that SOHO could warn us?
Not that it would matter! Since we'd be gittin killed shortly after we could see the carnage.
But SOHO could only transmit at the speed of light, the same speed that the light of the explosion would travel in the first place.
