 Extropist Philosophy

Endless eXtension - Extropists seek perpetual growth and progress in all aspects of human endeavor. We are, as a species and as a culture, never finished or in any essential way complete. Instead, we continually pursue knowledge, we constantly experiment, we forever continue to develop techniques that improve our minds, our bodies, our culture and our environment. Extropists affirm this belief and take it to its logical conclusion. We desire the technology and understanding that allows us to...

 Einstein's "Biggest Blunder"

For much of the modern era, scientists followed Nicolaus Copernicus, Galileo Galilei, and Isaac Newton in believing the cosmos to be eternal and unchanging. But in 1917, when Albert Einstein applied his theory of relativity to space-time as a whole, his equations implied that the universe could not be static; it must be either expanding or contracting. This struck Einstein as grotesque, so he added to his theory a fiddle factor called the "cosmological constant" that eliminated the implicatio...

 Origins of the Big Bang Theory and Evidence For It

That the universe is expanding was news to Einstein. But the possibility that the galaxies are moving away from each other had been proposed a few years before Hubble's papers on theoretical grounds arising from Einstein's own equations. In 1922, Russian physicist and mathematician Alexander Friedmann investigated what would happen in a model universe based upon two assumptions that greatly simplified the mathematics: that the universe looks identical in every direction, and that it looks tha...

 The plural of anecdote is not data

A common way anecdotal evidence becomes unscientific is through fallacious reasoning such as the Post hoc ergo propter hoc fallacy, the human tendency to assume that if one event happens after another, then the first must be the cause of the second. Another fallacy involvesinductive reasoning. For instance, if an anecdote illustrates a desired conclusion rather than a logical conclusion, it is considered a faulty orhasty generalization.[10] For example, here is anecdotal evidence...
