Greeting Kerbals Reading stuff about space is kinda a passion for me, be it actual science discoveries, or sci-fi. A little while ago, I was tidying my house, and stumbled upon a 38 year old book, called "GREAT MYSTERIES: Mysteries of the Universe" By Stemman, Roy, Published by Aldus Books in 1978. Mind you, the book is 12 years older than me (it was a gift from my grand-ma) and while I strongly suspect it to be mostly "popular science" with some sci-fi toward the end, rather than actual science publication, it is still a great read. In this book, they relate theories about black holes, and one in particular caught my attention, be ready : "Scientist could possibly create tiny black holes within a terrestrial laboratory. However, If they happens to succeed, the result would be catastrophic; According to the British professor, John Taylor : "A black hole with a mass of 1600tonnes, if left alone, would quickly sink toward the center of our planet, eating it rather swiftly, and us with it. And for good measure, Taylor added :" Even if there is a single black hole in our galaxy, then our futur is really dark, as it'll end up devouring us all." (Please excuse me if it's not the exact same text, as mine is translated in french, so I had to re-translate in english for the forum ) (We of course know this is partly wrong, as we had unknowingly a supermassive black hole in the center of our galaxy for billions of years, and by today's knowledge, it IS a fact, probably he meant on the long run, but we also do know that our sun will die out waaay before the milky way's black hole swallow us, sooo not really a problem, we also know that there is millions of smaller black holes everywhere in the galaxy, remnant of collapsed giant stars if I'm not wrong) They also suggest that if a spaceship could go through the Schwarzschild radius of a Black Hole without being reduced to space dust from the tidal forces, the spaceship would end up in a different universe. If the spaceship went through the same black hole he came from, it would end up in yet another universe, and another, and another, without being able to ever come back to it's origin. Keep in mind the following : "Our readers will understand that 'Black Holes' are purely the result of mathematical speculation, and is not based on any sort of evidence." which was probably true when the book was published. Given today's standard and knowledge about these mythical beasts, do you think a black hole weighting less than a Frigate class warship, could survive hawking radiation and eat through the earth ? (hmm, let me rephrase : What if a proton suddenly weighted 1600tonnes, would it become a self sustainable black hole ?) How about black holes being wormholes toward another universe ? (no this isn't another OMAGAD LHC IS GONNA DOOM US ALLL!!!1111)
