I deleted this:
"Other examples of space woo are scary stories about comets or asteroids which are going to smack into the Earth at any minute. However, just like earthquakes, rocks in space are subject to the law of the numerous small. Before we should expect to see a single world-destroying rock (or earthquake) hit us, we should see a number of country-destroying ones. And we should expect to see an even greater number of city-destroying ones. To scare people with stories that the next disaster will end the world, one must assert a major statistical spike, an outlier of extraordinary dimensions. And that's where the woo comes in, with Mayan calendars and the like."
from the article for being irrelevant and, to an extent, scientifically moribund. "city-destroying ones"??? Rocks crash into the earth with regularity (big ones, far less often than small ones), and the ones that leave any impact tend to leave a global impact (dust in the sky, etc.) more than a local-only impact. Also, why would they hit cities, when most of earth's surface is "not city" - even the land surface? And "country-destroying" is just bizarre - countries range in size from continental to tiny in extent, and, again, in the sphere of astrophysics/geography/geology have no meaning. In the end, I couldn't figure out what the point of this addition was, so I deleted it. SusanG reminded me to copy it here for discussion. ħuman 23:33, 30 September 2008 (EDT)
Should it be called "Scientific woo" or "Woo in science" instead of "Science woo"? Thieh 15:06, 3 May 2009 (UTC)
- Before silver, I'd certainly like to to see the "Cryonics, transhumanism, the Singularity" section summarize the beliefs of this group a little more, rather than just saying what we can't do and what is impossible. I've read all of our articles on it, but know no more... so if someone wants to to it, great. I'll come back in a week and do it if nobody else wants to. EXTERMINATE 13:40, 23 November 2010 (UTC)
Energy from the spinning Earth
This is actually not as difficult as the article currently states, because we're fortunate enough to have a "conveniently" placed large mass in space that we can use as an angular momentum sink: the moon. [Tidal power] ultimately comes from the rotation of the Earth-Moon system. — Unsigned, by: CronoDAS / talk / contribs (signed by bot) 21:34, 19 August 2014 (UTC)
