If we sow the seeds now, we may have other worlds to move to in a few million years - long before we may need it - such as in five billion years when the Sun has expired into a Red Giant. Whimsical Notions or Planning With Foresight? Unless we cause our own demise by inadvertently engineering our downfall, as often discussed here, or are struck by a statistically unfortunate large asteroid impact, Life is here on Earth for the long haul - it has been durable for billions of years, albeit with significant setbacks, and one can expect it will be here for billions more to come. We can get caught up in the concept that preservation of Human Life as the ultimate goal, in how do we colonize other worlds as soon as possible - but perhaps the most honorable pursuit is the propagation of Life itself - we should be introducing bacteria or simple xerophytic plants to Mars, algae to Europa and such worlds, in the anticipation that if a foothold can be taken, evolution could take hold - and we may not live to see it - but we have then passed on the gift of life to another world. I understand NASA want to explore Mars for signs of Martian life - but which is more important - to explore whether Life almost evolved on Mars, or to induce the whole process and allow it to occur? It is with great bewilderment that I read the precautions that NASA rovers are sterilized to, to ensure that Life does not infect the Martian environment. Crane & Westmoreland were presenting an academic exercise to pose “many interesting problems for classical and quantum relativity”.Ĭontinue reading “Debunking the Black Hole Interstellar Drive” » Whatever the other merits of our proposal, we are confident it will pose many interesting problems for classical and quantum relativity.” The conclusion we reach is that it is just on the edge of possibility to do so, but that quantum gravity effects, as yet unknown, could change the picture either way… Many questions which arise in this program lead to calculations in general relativity which have not been done. “The purpose of this paper is to investigate whether it is possible to build artificial BHs of the appropriate size, and to employ them in powerplants and starships. To give them credit, they stated that this is at the “edge of possibility” and would only be possible in the very distant future: Louis Crane and Shawn Westmoreland co-authored the paper Are Black Hole Starships Possible? ( ) that suggested that one could use Small Black Holes to propel starships close to the velocity of light for interstellar travel.
