Actually it may not be necessarily natural. There are two extremes to this spectrum. One end is believing that scientist know it all and that this is all "natural" whilst the other end of the spectrum there is believing every uneducated conspiracy theory out there. Obviously Terral is horribly flawed. He is too assured that it's Elenin (which he thinks isn't a comet) is causing all the problems in our solar system. It's too early to be "sure" about anything.
